139-515: The Pacific geoduck ( / ˈ ɡ uː i ˌ d ʌ k / GOO-ee-duk ; Panopea generosa ) is a species of very large saltwater clam in the family Hiatellidae . The common name is derived from the Lushootseed name, gʷidəq . The geoduck is native to the coastal waters of the eastern North Pacific Ocean from Alaska to Baja California. The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but
278-453: A moment magnitude of 9.2 (more than a thousand times as powerful as the 1989 San Francisco earthquake ). The time of day (5:36 pm), time of year (spring) and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage. Alaska suffered a more severe megathrust earthquake on July 11, 1585, estimated at magnitude 9.25, which remains
417-423: A mutation–selection balance . It is predicted that a viral quasispecies at a low but evolutionarily neutral and highly connected (that is, flat) region in the fitness landscape will outcompete a quasispecies located at a higher but narrower fitness peak in which the surrounding mutants are unfit, "the quasispecies effect" or the "survival of the flattest". There is no suggestion that a viral quasispecies resembles
556-409: A territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959. Abundant natural resources have enabled Alaska— with one of the smallest state economies—to have one of the highest per capita incomes , with commercial fishing , and the extraction of natural gas and oil, dominating Alaska's economy . U.S. Armed Forces bases and tourism also contribute to
695-400: A "classical" method of determining species, such as with Linnaeus, early in evolutionary theory. However, different phenotypes are not necessarily different species (e.g. a four-winged Drosophila born to a two-winged mother is not a different species). Species named in this manner are called morphospecies . In the 1970s, Robert R. Sokal , Theodore J. Crovello and Peter Sneath proposed
834-424: A 'smallest clade' idea" (a phylogenetic species concept). Mishler and Wilkins and others concur with this approach, even though this would raise difficulties in biological nomenclature. Wilkins cited the ichthyologist Charles Tate Regan 's early 20th century remark that "a species is whatever a suitably qualified biologist chooses to call a species". Wilkins noted that the philosopher Philip Kitcher called this
973-428: A connected series of neighbouring populations, each of which can sexually interbreed with adjacent related populations, but for which there exist at least two "end" populations in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population. Such non-breeding, though genetically connected, "end" populations may co-exist in the same region thus closing
1112-399: A convoy to Valdez. On the advice of military and civilian leaders, President Lyndon B. Johnson declared all of Alaska a major disaster area the day after the quake. The U.S. Navy and U.S. Coast Guard deployed ships to isolated coastal communities to assist with immediate needs. Bad weather and poor visibility hampered air rescue and observation efforts the day after the quake, but on Sunday
1251-432: A different species from its ancestors. Viruses have enormous populations, are doubtfully living since they consist of little more than a string of DNA or RNA in a protein coat, and mutate rapidly. All of these factors make conventional species concepts largely inapplicable. A viral quasispecies is a group of genotypes related by similar mutations, competing within a highly mutagenic environment, and hence governed by
1390-508: A genetic boundary suitable for defining a species concept is present. DNA barcoding has been proposed as a way to distinguish species suitable even for non-specialists to use. One of the barcodes is a region of mitochondrial DNA within the gene for cytochrome c oxidase . A database, Barcode of Life Data System , contains DNA barcode sequences from over 190,000 species. However, scientists such as Rob DeSalle have expressed concern that classical taxonomy and DNA barcoding, which they consider
1529-465: A lineage should be divided into multiple chronospecies , or when populations have diverged to have enough distinct character states to be described as cladistic species. Species and higher taxa were seen from the time of Aristotle until the 18th century as categories that could be arranged in a hierarchy, the great chain of being . In the 19th century, biologists grasped that species could evolve given sufficient time. Charles Darwin 's 1859 book On

Alaska is more than twice the size of the second-largest U.S. state (Texas), and it is larger than the next three largest states (Texas, California, and Montana) combined. Alaska is the seventh largest subnational division in

Nearby, a 27-foot (8.2 m) tsunami destroyed the village of Chenega , killing 23 of the 68 people who lived there; survivors out-ran the wave, climbing to high ground. Post-quake tsunamis severely affected Whittier , Seward , Kodiak, and other Alaskan communities, as well as people and property in British Columbia, Washington , Oregon , and California . Tsunamis also caused damage in Hawaii and Japan . Evidence of motion directly related to
1946-492: A misnomer, need to be reconciled, as they delimit species differently. Genetic introgression mediated by endosymbionts and other vectors can further make barcodes ineffective in the identification of species. A phylogenetic or cladistic species is "the smallest aggregation of populations (sexual) or lineages (asexual) diagnosable by a unique combination of character states in comparable individuals (semaphoronts)". The empirical basis – observed character states – provides
2085-801: A much higher market value live, an additional $ 4.4 to $ 6.6 per kilogram or $ 2 to $ 3 per pound, this development has helped to stimulate the burgeoning industry. The COVID-19 pandemic disrupted the geoduck industry. Given the near-shutdown of restaurants and seafood markets across the country, demand for live geoducks plummeted. Divers in Southeast Alaska who typically see prices of $ 11 to $ 22 per kilogram or $ 5 to $ 10 per pound for live geoducks reported prices as low as $ 2.2 per kilogram or $ 1 per pound, leading many to stop fishing temporarily. Geoduck farming grow-out and harvest practices are controversial, and have created conflicts with shoreline property owners, and concerns from nongovernmental organizations. However,
2224-449: A particular species, including which genus (and higher taxa) it is placed in, is a hypothesis about the evolutionary relationships and distinguishability of that group of organisms. As further information comes to hand, the hypothesis may be corroborated or refuted. Sometimes, especially in the past when communication was more difficult, taxonomists working in isolation have given two distinct names to individual organisms later identified as
2363-400: A perfect model of life, it is still a useful tool to scientists and conservationists for studying life on Earth, regardless of the theoretical difficulties. If species were fixed and clearly distinct from one another, there would be no problem, but evolutionary processes cause species to change. This obliges taxonomists to decide, for example, when enough change has occurred to declare that

Ben Potter, the University of Alaska Fairbanks archaeologist who unearthed the remains at the Upward Sun River site in 2013, named this new group Ancient Beringian . The Tlingit people developed a society with a matrilineal kinship system of property inheritance and descent in what

It is sometimes known as a mud duck , king clam or, when translated literally from Chinese , an elephant-trunk clam ( Chinese : 象拔蚌 ; pinyin : xiàngbábàng ; Jyutping : zoeng6 bat6 pong5 ). Between 1983 and 2010,
2780-400: A short way of saying that something applies to many species within a genus, but not to all. If scientists mean that something applies to all species within a genus, they use the genus name without the specific name or epithet. The names of genera and species are usually printed in italics . However, abbreviations such as "sp." should not be italicised. When a species' identity is not clear,
2919-404: A specialist may use "cf." before the epithet to indicate that confirmation is required. The abbreviations "nr." (near) or "aff." (affine) may be used when the identity is unclear but when the species appears to be similar to the species mentioned after. With the rise of online databases, codes have been devised to provide identifiers for species that are already defined, including: The naming of

#17328595371733058-523: A species as groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups. It has been argued that this definition is a natural consequence of the effect of sexual reproduction on the dynamics of natural selection. Mayr's use of the adjective "potentially" has been a point of debate; some interpretations exclude unusual or artificial matings that occur only in captivity, or that involve animals capable of mating but that do not normally do so in
3197-400: A species as determined by a taxonomist. A typological species is a group of organisms in which individuals conform to certain fixed properties (a type), so that even pre-literate people often recognise the same taxon as do modern taxonomists. The clusters of variations or phenotypes within specimens (such as longer or shorter tails) would differentiate the species. This method was used as
3336-488: A species. All species definitions assume that an organism acquires its genes from one or two parents very like the "daughter" organism, but that is not what happens in HGT. There is strong evidence of HGT between very dissimilar groups of prokaryotes , and at least occasionally between dissimilar groups of eukaryotes , including some crustaceans and echinoderms . The evolutionary biologist James Mallet concludes that there
3475-685: A species. Generally the term includes the unknown element of a distinct act of creation. Many authors have argued that a simple textbook definition, following Mayr's concept, works well for most multi-celled organisms , but breaks down in several situations: Species identification is made difficult by discordance between molecular and morphological investigations; these can be categorised as two types: (i) one morphology, multiple lineages (e.g. morphological convergence , cryptic species ) and (ii) one lineage, multiple morphologies (e.g. phenotypic plasticity , multiple life-cycle stages). In addition, horizontal gene transfer (HGT) makes it difficult to define
3614-519: A taxonomic decision at the discretion of cognizant specialists, is not governed by the Codes of Zoological or Botanical Nomenclature, in contrast to the PhyloCode , and contrary to what is done in several other fields, in which the definitions of technical terms, like geochronological units and geopolitical entities, are explicitly delimited. The nomenclatural codes that guide the naming of species, including

The United States Lend-Lease program involved flying American warplanes through Canada to Fairbanks and then Nome ; Soviet pilots took possession of these aircraft, ferrying them to fight
3892-506: A traditional biological species. The International Committee on Taxonomy of Viruses has since 1962 developed a universal taxonomic scheme for viruses; this has stabilised viral taxonomy. Most modern textbooks make use of Ernst Mayr 's 1942 definition, known as the Biological Species Concept as a basis for further discussion on the definition of species. It is also called a reproductive or isolation concept. This defines
4031-447: A variation on the morphological species concept, a phenetic species, defined as a set of organisms with a similar phenotype to each other, but a different phenotype from other sets of organisms. It differs from the morphological species concept in including a numerical measure of distance or similarity to cluster entities based on multivariate comparisons of a reasonably large number of phenotypic traits. A mate-recognition species
4170-515: A variety of reasons. Viruses are a special case, driven by a balance of mutation and selection , and can be treated as quasispecies . Biologists and taxonomists have made many attempts to define species, beginning from morphology and moving towards genetics . Early taxonomists such as Linnaeus had no option but to describe what they saw: this was later formalised as the typological or morphological species concept. Ernst Mayr emphasised reproductive isolation, but this, like other species concepts,
4309-438: Is "an entity composed of organisms which maintains its identity from other such entities through time and over space, and which has its own independent evolutionary fate and historical tendencies". This differs from the biological species concept in embodying persistence over time. Wiley and Mayden stated that they see the evolutionary species concept as "identical" to Willi Hennig 's species-as-lineages concept, and asserted that

Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and
4587-400: Is a group of sexually reproducing organisms that recognise one another as potential mates. Expanding on this to allow for post-mating isolation, a cohesion species is the most inclusive population of individuals having the potential for phenotypic cohesion through intrinsic cohesion mechanisms; no matter whether populations can hybridise successfully, they are still distinct cohesion species if
4726-458: Is a set of organisms adapted to a particular set of resources, called a niche, in the environment. According to this concept, populations form the discrete phenetic clusters that we recognise as species because the ecological and evolutionary processes controlling how resources are divided up tend to produce those clusters. A genetic species as defined by Robert Baker and Robert Bradley is a set of genetically isolated interbreeding populations. This

A 2004 draft biological assessment, commissioned by three of the largest commercial shellfish companies in the Puget Sound region, identified no long-term effects of geoduck farming on threatened or endangered species. The large, meaty siphon is prized for its savory flavor and crunchy texture. Geoduck is regarded by some as an aphrodisiac because of its phallic shape. It is very popular in China , where it

Some modern researchers associate Kheuveren with Koyuk River . The first European vessel to reach Alaska is generally held to be the St. Gabriel under the authority of the surveyor M. S. Gvozdev and assistant navigator I. Fyodorov on August 21, 1732, during an expedition of Siberian Cossack A. F. Shestakov and Russian explorer Dmitry Pavlutsky (1729–1735). Another European contact with Alaska occurred in 1741, when Vitus Bering led an expedition for

Alaska's territorial waters touch Russia's territorial waters in the Bering Strait, as the Russian Big Diomede Island and Alaskan Little Diomede Island are only 3 miles (4.8 km) apart. Alaska has
5282-414: Is called speciation . Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book The Origin of Species . Speciation depends on a measure of reproductive isolation , a reduced gene flow. This occurs most easily in allopatric speciation, where populations are separated geographically and can diverge gradually as mutations accumulate. Reproductive isolation
5421-412: Is called the specific name or the specific epithet (in botanical nomenclature , also sometimes in zoological nomenclature ). For example, Boa constrictor is one of the species of the genus Boa , with constrictor being the species' epithet. While the definitions given above may seem adequate at first glance, when looked at more closely they represent problematic species concepts. For example,
5560-449: Is considered a delicacy , mostly eaten cooked in a fondue-style Chinese hot pot. In Korean cuisine , geoducks are eaten raw with spicy chili sauce, sautéed, or in soups and stews. In Japan , geoduck is prepared as raw sashimi , dipped in soy sauce and wasabi . On Japanese menus in cheaper sushi restaurants, geoduck is sometimes substituted for Tresus keenae , a species of horse clam , and labeled mirugai or mirukuigai . It

The largest quantities have come from Golden Bay in the South Island where 100 tonnes (110 short tons) were harvested in one year. There is a growing concern over the increase of parasites in the Puget Sound population of geoduck. Whether these microsporidium -like parasitic species were introduced by commercial farming is being studied by Sea Grant. Research to date does indicate their presence. The oldest recorded specimen

For example, the dandelion Taraxacum officinale and the blackberry Rubus fruticosus are aggregates with many microspecies—perhaps 400 in the case of the blackberry and over 200 in the dandelion, complicated by hybridisation , apomixis and polyploidy , making gene flow between populations difficult to determine, and their taxonomy debatable. Species complexes occur in insects such as Heliconius butterflies, vertebrates such as Hypsiboas treefrogs, and fungi such as
6394-726: Is hard or even impossible to test. Later biologists have tried to refine Mayr's definition with the recognition and cohesion concepts, among others. Many of the concepts are quite similar or overlap, so they are not easy to count: the biologist R. L. Mayden recorded about 24 concepts, and the philosopher of science John Wilkins counted 26. Wilkins further grouped the species concepts into seven basic kinds of concepts: (1) agamospecies for asexual organisms (2) biospecies for reproductively isolated sexual organisms (3) ecospecies based on ecological niches (4) evolutionary species based on lineage (5) genetic species based on gene pool (6) morphospecies based on form or phenotype and (7) taxonomic species,

One is forced to admit that Darwin's insight is correct: any local reality or integrity of species is greatly reduced over large geographic ranges and time periods. The botanist Brent Mishler argued that the species concept

Indeed, complex and unstable patterns of gene flux have been observed in cichlid teleosts of the East African Great Lakes .

In the 21st century, a genetic species could be established by comparing DNA sequences. Earlier, other methods were available, such as comparing karyotypes (sets of chromosomes ) and allozymes ( enzyme variants). An evolutionarily significant unit (ESU) or "wildlife species" is a population of organisms considered distinct for purposes of conservation. In palaeontology , with only comparative anatomy (morphology) and histology from fossils as evidence,

10425-406: The "cynical species concept", and arguing that far from being cynical, it usefully leads to an empirical taxonomy for any given group, based on taxonomists' experience. Other biologists have gone further and argued that we should abandon species entirely, and refer to the "Least Inclusive Taxonomic Units" (LITUs), a view that would be coherent with current evolutionary theory. The species concept
10564-465: The 29th the situation improved and rescue helicopters and observation aircraft were deployed. A military airlift immediately began shipping relief supplies to Alaska, eventually delivering 2,570,000 pounds (1,170,000 kg) of food and other supplies. Broadcast journalist, Genie Chance , assisted in recovery and relief efforts, staying on the KENI air waves over Anchorage for more than 24 continuous hours as
10703-656: The Alaska Division of Emergency Services to respond to any future disasters. The 1968 discovery of oil at Prudhoe Bay and the 1977 completion of the Trans-Alaska Pipeline System led to an oil boom. Royalty revenues from oil have funded large state budgets from 1980 onward. Oil production was not the only economic value of Alaska's land. In the second half of the 20th century, Alaska discovered tourism as an important source of revenue. Tourism became popular after World War II when military personnel stationed in
10842-661: The German invasion of the Soviet Union . The construction of military bases contributed to the population growth of some Alaskan cities. Statehood for Alaska was an important cause of James Wickersham early in his tenure as a congressional delegate. Decades later, the statehood movement gained its first real momentum following a territorial referendum in 1946. The Alaska Statehood Committee and Alaska's Constitutional Convention would soon follow. Statehood supporters also found themselves fighting major battles against political foes, mostly in
10981-573: The North Slope and of the Northwest Arctic seldom consider themselves to be one people. Southwest Alaska is a sparsely inhabited region stretching some 500 miles (800 km) inland from the Bering Sea. Most of the population lives along the coast. Kodiak Island is also located in the Southwest. The massive Yukon–Kuskokwim Delta , one of the largest river deltas in the world, is here. Portions of
11120-622: The Origin of Species explained how species could arise by natural selection . That understanding was greatly extended in the 20th century through genetics and population ecology . Genetic variability arises from mutations and recombination , while organisms themselves are mobile, leading to geographical isolation and genetic drift with varying selection pressures . Genes can sometimes be exchanged between species by horizontal gene transfer ; new species can arise rapidly through hybridisation and polyploidy ; and species may become extinct for
11259-573: The Pacific Northwest Coast , experienced smallpox outbreaks from the late 18th through the mid- 19th century , with the most devastating epidemics occurring in the 1830s and 1860s, resulting in high fatalities and social disruption. Some researchers believe the first Russian settlement in Alaska was established in the 17th century. According to this hypothesis, in 1648 several koches of Semyon Dezhnyov 's expedition came ashore in Alaska by storm and founded this settlement. This hypothesis
11398-595: The Pacific Northwest. In 1789, a Spanish settlement and fort were built in Nootka Sound . These expeditions gave names to places such as Valdez , Bucareli Sound , and Cordova . Later, the Russian-American Company carried out an expanded colonization program during the early-to-mid-19th century. Sitka , renamed New Archangel from 1804 to 1867, on Baranof Island in the Alexander Archipelago in what
11537-627: The Pacific Ocean. Some of these islands fall in the Eastern Hemisphere, but the International Date Line was drawn west of 180° to keep the whole state, and thus the entire North American continent, within the same legal day. Two of the islands, Attu and Kiska , were occupied by Japanese forces during World War II. According to an October 1998 report by the United States Bureau of Land Management , approximately 65% of Alaska
11676-456: The Russian Navy aboard the St. Peter . After his crew returned to Russia with sea otter pelts judged to be the finest fur in the world, small associations of fur traders began to sail from the shores of Siberia toward the Aleutian Islands. The first permanent European settlement was founded in 1784. Between 1774 and 1800, Spain sent several expeditions to Alaska to assert its claim over
11815-436: The U.S. Congress but also within Alaska. Statehood was approved by the U.S. Congress on July 7, 1958; Alaska was officially proclaimed a state on January 3, 1959. On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the fourth-most-powerful earthquake in recorded history, with
11954-846: The US states of Alaska , Washington , and Oregon and the Canadian province of British Columbia . It is one of the most closely regulated fisheries in both countries. In Washington, Department of Natural Resources staff are on the water continually monitoring harvests to ensure revenues are received, and the same is true in Canada where the Underwater Harvesters' Association manages the Canadian Fishery in conjunction with Canada's Department of Fisheries and Oceans. The Washington State Department of Health tests water and flesh to assure clams are not filtering and holding pollutants, an ongoing problem. With
12093-405: The abbreviation "sp." in the singular or "spp." (standing for species pluralis , Latin for "multiple species") in the plural in place of the specific name or epithet (e.g. Canis sp.). This commonly occurs when authors are confident that some individuals belong to a particular genus but are not sure to which exact species they belong, as is common in paleontology . Authors may also use "spp." as
12232-559: The action of the sea is directed". Numerous indigenous peoples occupied Alaska for thousands of years before the arrival of European peoples to the area. Linguistic and DNA studies done here have provided evidence for the settlement of North America by way of the Bering land bridge . At the Upward Sun River site in the Tanana Valley in Alaska, remains of a six-week-old infant were found. The baby's DNA showed that she belonged to
12371-570: The amount of hybridisation is insufficient to completely mix their respective gene pools . A further development of the recognition concept is provided by the biosemiotic concept of species. In microbiology , genes can move freely even between distantly related bacteria, possibly extending to the whole bacterial domain. As a rule of thumb, microbiologists have assumed that members of Bacteria or Archaea with 16S ribosomal RNA gene sequences more similar than 97% to each other need to be checked by DNA–DNA hybridisation to decide if they belong to
12510-474: The biological species concept, "the several versions" of the phylogenetic species concept, and the idea that species are of the same kind as higher taxa are not suitable for biodiversity studies (with the intention of estimating the number of species accurately). They further suggested that the concept works for both asexual and sexually-reproducing species. A version of the concept is Kevin de Queiroz 's "General Lineage Concept of Species". An ecological species
12649-505: The biological species concept, a cladistic species does not rely on reproductive isolation – its criteria are independent of processes that are integral in other concepts. Therefore, it applies to asexual lineages. However, it does not always provide clear cut and intuitively satisfying boundaries between taxa, and may require multiple sources of evidence, such as more than one polymorphic locus, to give plausible results. An evolutionary species, suggested by George Gaylord Simpson in 1951,
12788-428: The boundaries between closely related species become unclear with hybridisation , in a species complex of hundreds of similar microspecies , and in a ring species . Also, among organisms that reproduce only asexually , the concept of a reproductive species breaks down, and each clone is potentially a microspecies. Although none of these are entirely satisfactory definitions, and while the concept of species may not be
12927-489: The ceremony, 250 uniformed U.S. soldiers marched to the governor's house at "Castle Hill", where the Russian troops lowered the Russian flag and the U.S. flag was raised. This event is celebrated as Alaska Day , a legal holiday on October 18. Alaska was loosely governed by the military initially and was administered as a district starting in 1884, with a governor appointed by the United States president. A federal district court
13066-539: The city proper and the communities of Eagle River, Chugiak, Peters Creek, Girdwood, Bird, and Indian. Fairbanks has a separate borough (the Fairbanks North Star Borough ) and municipality (the City of Fairbanks). The state's most populous city is Anchorage , home to 291,247 people in 2020. The richest location in Alaska by per capita income is Denali ($ 42,245). Yakutat City , Sitka, Juneau, and Anchorage are
13205-429: The community, disseminating information about shelters and prepared food rations, passing messages of well-being between loved ones, and helping to reunite families. In the longer term, the U.S. Army Corps of Engineers led the effort to rebuild roads, clear debris, and establish new townsites for communities that had been completely destroyed, at a cost of $ 110 million. The West Coast and Alaska Tsunami Warning Center
13344-433: The concept of a chronospecies can be applied. During anagenesis (evolution, not necessarily involving branching), some palaeontologists seek to identify a sequence of species, each one derived from the phyletically extinct one before through continuous, slow and more or less uniform change. In such a time sequence, some palaeontologists assess how much change is required for a morphologically distinct form to be considered
13483-416: The concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses ) are given a two-part name , called a "binomial". The first part of a binomial is the genus to which the species belongs. The second part
13622-410: The contiguous North American road system. The Interior is the largest region of Alaska; much of it is uninhabited wilderness. Fairbanks is the only large city in the region. Denali National Park and Preserve is located here. Denali , formerly Mount McKinley, is the highest mountain in North America and is also located here. The North Slope is mostly tundra peppered with small villages. The area
13761-456: The damage done by the earthquake to the city. The team, called the Engineering and Geological Evaluation Group, was headed by Ruth A. M. Schmidt , a geology professor at the University of Alaska Anchorage . The team of scientists came into conflict with local developers and downtown business owners who wanted to immediately rebuild; the scientists wanted to identify future dangers to ensure that
13900-512: The earthquake was also reported from Florida and Texas . Alaska had never experienced a major disaster in a highly populated area before and had very limited resources for dealing with the effects of such an event. In Anchorage, at the urging of geologist Lidia Selkregg , the City of Anchorage and the Alaska State Housing Authority appointed a team of 40 scientists, including geologists, soil scientists, and engineers, to assess
14039-458: The economy; more than half of the state is federally-owned land containing national forests , national parks , and wildlife refuges . It is among the most irreligious states , one of the first to legalize recreational marijuana , and is known for its libertarian-leaning political culture, generally supporting the Republican Party in national elections. The Indigenous population of Alaska
14178-435: The evidence to support hypotheses about evolutionarily divergent lineages that have maintained their hereditary integrity through time and space. Molecular markers may be used to determine diagnostic genetic differences in the nuclear or mitochondrial DNA of various species. For example, in a study done on fungi , studying the nucleotide characters using cladistic species produced the most accurate results in recognising
14317-532: The exposed geoduck siphon. Geoducks are broadcast spawners. A female geoduck produces about 5 billion eggs in her century-long lifespan. However, due to a low rate of recruitment and a high rate of mortality for geoduck eggs, larvae, and post-settled juveniles, populations are slow to rebound. In the Puget Sound, studies indicate that the recovery time for a harvested tract is 39 years. Biomass densities in Southeast Alaska are estimated by divers, then inflated by twenty percent to account for geoducks not visible at
14456-431: The extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. It is also one of the longest-living animals of any type, with a typical lifespan of 140 years; the oldest has been recorded at 179 years old. The precise longevity of geoducks can be determined from annual rings deposited in
14595-467: The following three largest states of Texas , California , and Montana combined, and is the seventh-largest subnational division in the world . It is the third-least populous and most sparsely populated U.S. state, but is, with a population of 736,081 as of 2020 , the continent's most populous territory located mostly north of the 60th parallel , with more than quadruple the combined populations of Northern Canada and Greenland . The state contains
14734-481: The four largest cities in the U.S. by area . As reflected in the 2020 United States census , Alaska has a total of 355 incorporated cities and census-designated places (CDPs). The tally of cities includes four unified municipalities, essentially the equivalent of a consolidated city–county . The majority of these communities are located in the rural expanse of Alaska known as " The Bush " and are unconnected to that contiguous North American road network. The table at
14873-416: The four largest cities in the United States by area , including the state capital of Juneau . The state's most populous city is Anchorage , and approximately half of Alaska's residents live within its metropolitan area . Indigenous people have lived in Alaska for thousands of years, and it is widely believed that the region served as the entry point for the initial settlement of North America by way of
15012-432: The largest private landowner in Alaska in advertisements and other communications. Provisions of ANCSA allowing the corporations' land holdings to be sold on the open market starting in 1991 were repealed before they could take effect. Effectively, the corporations hold title (including subsurface title in many cases, a privilege denied to individual Alaskans) but cannot sell the land. Individual Native allotments are sold on
15151-610: The low population density, most of the land is located in the Unorganized Borough . As the name implies, it has no intermediate borough government but is administered directly by the state government. In 2000, 57.71% of Alaska's area has this status, with 13.05% of the population. Anchorage merged the city government with the Greater Anchorage Area Borough in 1975 to form the Municipality of Anchorage, containing
15290-801: The most powerful earthquake recorded in North American history, and the second most powerful earthquake recorded in world history. The Good Friday earthquake lasted 4 minutes and 38 seconds. Six hundred miles (970 km) of fault ruptured at once and moved up to 60 ft (18 m), releasing about 500 years of stress buildup. Soil liquefaction , fissures, landslides, and other ground failures caused major structural damage in several communities and much damage to property. Anchorage sustained great destruction or damage to many inadequately earthquake-engineered houses, buildings, and infrastructure (paved streets, sidewalks, water and sewer mains, electrical systems, and other human-made equipment), particularly in
15429-478: The numerous fungi species of all the concepts studied. Versions of the phylogenetic species concept that emphasise monophyly or diagnosability may lead to splitting of existing species, for example in Bovidae , by recognising old subspecies as species, despite the fact that there are no reproductive barriers, and populations may intergrade morphologically. Others have called this approach taxonomic inflation , diluting
15568-508: The often remote and roadless locations. The University of Alaska , as a land grant university , also owns substantial acreage which it manages independently. Another 44 million acres (18 million hectares) are owned by 12 regional, and scores of local, Native corporations created under the Alaska Native Claims Settlement Act (ANCSA) of 1971. Regional Native corporation Doyon, Limited often promotes itself as
15707-412: The open market. Various private interests own the remaining land, totaling about one percent of the state. Alaska is, by a large margin, the state with the smallest percentage of private land ownership when Native corporation holdings are excluded. The Alaska Heritage Resources Survey (AHRS) is a restricted inventory of all reported historic and prehistoric sites within the U.S. state of Alaska; it
15846-585: The paper is accepted for publication. The type material is usually held in a permanent repository, often the research collection of a major museum or university, that allows independent verification and the means to compare specimens. Describers of new species are asked to choose names that, in the words of the International Code of Zoological Nomenclature , are "appropriate, compact, euphonious, memorable, and do not cause offence". Books and articles sometimes intentionally do not identify species fully, using
15985-674: The person who named the species, while the antonym sensu lato ("in the broad sense") denotes a wider usage, for instance including other subspecies. Other abbreviations such as "auct." ("author"), and qualifiers such as "non" ("not") may be used to further clarify the sense in which the specified authors delineated or described the species. Species are subject to change, whether by evolving into new species, exchanging genes with other species, merging with other species or by becoming extinct. The evolutionary process by which biological populations of sexually-reproducing organisms evolve to become distinct or reproductively isolated as species
16124-544: The phallic appearance of their siphons. Species A species ( pl. : species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring , typically by sexual reproduction . It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity . Other ways of defining species include their karyotype , DNA sequence, morphology , behaviour, or ecological niche . In addition, paleontologists use
16263-428: The rebuilt infrastructure would be safe. The team produced a report on May 8, 1964, just a little more than a month after the earthquake. The United States military, which has a large active presence in Alaska, also stepped in to assist within moments of the end of the quake. The U.S. Army rapidly re-established communications with the lower 48 states, deployed troops to assist the citizens of Anchorage, and dispatched
16402-590: The region returned home praising its natural splendor. The Alcan Highway , built during the war, and the Alaska Marine Highway System , completed in 1963, made the state more accessible than before. Tourism has become increasingly important in Alaska, and today over 1.4 million people visit the state each year. With tourism more vital to the economy, environmentalism also rose in importance. The Alaska National Interest Lands Conservation Act (ANILCA) of 1980 added 53.7 million acres (217,000 km ) to
16541-505: The remaining land area, the state of Alaska owns 101 million acres (41 million hectares), its entitlement under the Alaska Statehood Act . A portion of that acreage is occasionally ceded to the organized boroughs presented above, under the statutory provisions pertaining to newly formed boroughs. Smaller portions are set aside for rural subdivisions and other homesteading-related opportunities. These are not very popular due to
16680-487: The result of misclassification leading to questions on whether there really are any ring species. The commonly used names for kinds of organisms are often ambiguous: "cat" could mean the domestic cat, Felis catus , or the cat family, Felidae . Another problem with common names is that they often vary from place to place, so that puma, cougar, catamount, panther, painter and mountain lion all mean Puma concolor in various parts of America, while "panther" may also mean
16819-573: The ring. Ring species thus present a difficulty for any species concept that relies on reproductive isolation. However, ring species are at best rare. Proposed examples include the herring gull – lesser black-backed gull complex around the North pole, the Ensatina eschscholtzii group of 19 populations of salamanders in America, and the greenish warbler in Asia, but many so-called ring species have turned out to be
16958-580: The rise in price has come the inevitable problem with poaching, and with it the possibility some could be harvested from unsafe areas. As of 2007, advances in the testing system for contaminated clams have allowed geoduck harvesters to deliver live clams more consistently. The new testing system determines the viability of clams from tested beds before the harvesters fish the area. Previous methods tested clams after harvest. This advancement has meant that 90 percent of clams were delivered live to market in 2007. In 2001, only 10 percent were live. Because geoduck have
17097-508: The same species. This concept was narrowed in 2006 to a similarity of 98.7%. The average nucleotide identity (ANI) method quantifies genetic distance between entire genomes , using regions of about 10,000 base pairs . With enough data from genomes of one genus, algorithms can be used to categorize species, as for Pseudomonas avellanae in 2013, and for all sequenced bacteria and archaea since 2020. Observed ANI values among sequences appear to have an "ANI gap" at 85–95%, suggesting that
17236-529: The same species. When two species names are discovered to apply to the same species, the older species name is given priority and usually retained, and the newer name considered as a junior synonym, a process called synonymy . Dividing a taxon into multiple, often new, taxa is called splitting . Taxonomists are often referred to as "lumpers" or "splitters" by their colleagues, depending on their personal approach to recognising differences or commonalities between organisms. The circumscription of taxa, considered
17375-671: The scientific name of this clam was confused with that of an extinct clam, Panopea abrupta (Conrad, 1849), in scientific literature. Native to the west coast of Canada and the northwest coast of the United States (primarily Washington and British Columbia ), these marine bivalve mollusks are the largest burrowing clams in the world, weighing in at an average of 0.7 kilograms ( 1 + 1 ⁄ 2 lb) at maturity, but specimens weighing over 7 kilograms (15 lb) and as much as 2 metres (6 ft 7 in) in length are not unheard of. A related species, Panopea zelandica ,
17514-545: The several landslide zones along Knik Arm . Two hundred miles (320 km) southwest, some areas near Kodiak were permanently raised by 30 feet (9 m). Southeast of Anchorage, areas around the head of Turnagain Arm near Girdwood and Portage dropped as much as 8 feet (2.4 m), requiring reconstruction and fill to raise the Seward Highway above the new high tide mark. In Prince William Sound , Port Valdez suffered
17653-454: The shell which can be assigned to calendar years of formation through crossdating . These annual rings also serve as an archive of past marine variability. The name Geoduck is derived from the Lushootseed name for the animal, gʷidəq . The etymology of gʷidəq is disputed. The lexical suffix =əq means "many" in Lushootseed. The Oxford English Dictionary claims it is composed of
17792-502: The species concept and making taxonomy unstable. Yet others defend this approach, considering "taxonomic inflation" pejorative and labelling the opposing view as "taxonomic conservatism"; claiming it is politically expedient to split species and recognise smaller populations at the species level, because this means they can more easily be included as endangered in the IUCN red list and can attract conservation legislation and funding. Unlike
17931-461: The state's entire land area. The area not part of any borough is referred to as the Unorganized Borough . The Unorganized Borough has no government of its own, but the U.S. Census Bureau in cooperation with the state divided the Unorganized Borough into 11 census areas solely for the purposes of statistical analysis and presentation. A recording district is a mechanism for management of
18070-468: The time of survey. This estimate is used to predict the two percent allowed for commercial harvesting. The world's first geoduck fishery was created in 1970, but demand for the half-forgotten clam was low at first due to its texture. As of 2011, these clams sell in China for over US$ 33 per kilogram or $ 15 per pound. The geoduck's high market value has created an $ 80-million industry, with harvesting occurring in
18209-509: The voice of calm from her temporary post within the Anchorage Public Safety Building. She was effectively designated as the public safety officer by the city's police chief. Chance provided breaking news of the catastrophic events that continued to develop following the magnitude 9.2 earthquake, and she served as the voice of the public safety office, coordinating response efforts, connecting available resources to needs around
18348-537: The wild. It is difficult to define a species in a way that applies to all organisms. The debate about species concepts is called the species problem. The problem was recognised even in 1859, when Darwin wrote in On the Origin of Species : I was much struck how entirely vague and arbitrary is the distinction between species and varieties. He went on to write: No one definition has satisfied all naturalists; yet every naturalist knows vaguely what he means when he speaks of
18487-471: The world . If it was an independent nation, it would be the 18th largest country in the world; almost the same size as Iran . With its myriad of islands, Alaska has nearly 34,000 miles (55,000 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula . Many active volcanoes are found in the Aleutians and in coastal regions. Unimak Island , for example,
18626-513: The world's largest tides occurs in Turnagain Arm , just south of Anchorage, where tidal differences can be more than 35 feet (10.7 m). Alaska has more than 409,000 natural lakes at least one hectare or bigger. Marshlands and wetland permafrost cover 188,320 square miles (487,700 km ) (mostly in northern, western and southwest flatlands). Glacier ice covers about 28,957 square miles (75,000 km ) of Alaska. The Bering Glacier
18765-435: Was 179 years old, but individuals usually live up to 140 years. A geoduck sucks water containing plankton down through its long siphon, filters this for food and ejects its refuse out through a separate hole in the siphon. Adult geoducks have few natural predators , which may also contribute to their longevity. In Alaska , sea otters and dogfish have proved capable of dislodging geoducks; starfish also attack and feed on
18904-512: Was extremely limited or unavailable until statehood took effect in 1959. Starting in the 1890s and stretching in some places to the early 1910s, gold rushes in Alaska and the nearby Yukon Territory brought thousands of miners and settlers to Alaska. From 1879 to 1920, Alaska produced a cumulative total of over $ 460,000,000 ($ 6,691,927,500 inflation-adjusted) of mineral production. Alaska was officially incorporated as an organized territory in 1912. Alaska's capital, which had been in Sitka until 1906,
19043-483: Was formed as a direct response to the disaster. Federal disaster relief funds paid for reconstruction as well as financially supporting the devastated infrastructure of Alaska's government, spending hundreds of millions of dollars that helped keep Alaska financially solvent until the discovery of massive oil deposits at Prudhoe Bay . At the order of the U.S. Defense Department , the Alaska National Guard founded
19182-408: Was headquartered in Sitka. For most of Alaska's first decade under the United States flag, Sitka was the only community inhabited by American settlers. They organized a "provisional city government", which was Alaska's first municipal government, but not in a legal sense. Legislation allowing Alaskan communities to legally incorporate as cities did not come about until 1900, and home rule for cities
19321-701: Was moved north to Juneau . Construction of the Alaska Governor's Mansion began that same year. European immigrants from Norway and Sweden also settled in southeast Alaska, where they entered the fishing and logging industries. During World War II , the Aleutian Islands Campaign focused on Attu , Agattu and Kiska , all of which were occupied by the Empire of Japan . During the Japanese occupation, an American civilian and two United States Navy personnel were killed at Attu and Kiska respectively, and nearly
