104-523: The Zoological Society of London ( ZSL ) is a charity devoted to the worldwide conservation of animals and their habitats . It was founded in 1826. Since 1828, it has maintained London Zoo , and since 1931 Whipsnade Zoo . On 29 November 1822, the birthday of John Ray , "the father of modern zoology", a meeting held in the Linnean Society in Soho Square led by Rev. William Kirby , resolved to form

208-495: A species binomial (estimated range: 1.5–8 million). Less than 1% of all species that have been described beyond simply noting its existence. From these figures, the IUCN reports that 23% of vertebrates , 5% of invertebrates and 70% of plants that have been evaluated are designated as endangered or threatened . Better knowledge is being constructed by The Plant List for actual numbers of species. Systematic conservation planning

312-776: A wildlife sanctuary was founded on the Farne Islands by St Cuthbert in response to his religious beliefs. Natural history was a major preoccupation in the 18th century, with grand expeditions and the opening of popular public displays in Europe and North America . By 1900 there were 150 natural history museums in Germany , 250 in Great Britain , 250 in the United States , and 300 in France . Preservationist or conservationist sentiments are

416-609: A "Zoological Club of the Linnean Society of London". Between 1816 and 1826, discussions between Stamford Raffles, Humphry Davy, Joseph Banks and others led to the idea that London should have an establishment similar to the Jardin des Plantes in Paris. It would house a zoological collection "which should interest and amuse the public." The society was founded in April 1826 by Sir Stamford Raffles ,

520-510: A conservation project, it is important to understand how an ecosystem functions and what role different species and abiotic factors have within the system. It is important to have a precise reason for why ecological monitoring is implemented; within the context of conservation, this reasoning is often to track changes before, during, or after conservation measures are put in place to help a species or habitat recover from degradation and/or maintain integrity. Another benefit of ecological monitoring

624-443: A deeper understanding of disease through evolutionary medicine and to develop evolutionary therapies . Evolution plays a role in resistance of drugs; for example, how HIV becomes resistant to medications and the body's immune system. The mutation of resistance of HIV is due to the natural selection of the survivors and their offspring. The few HIV that survive the immune system reproduced and had offspring that were also resistant to

728-417: A development of the late 18th to early 20th centuries. Before Charles Darwin set sail on HMS Beagle , most people in the world, including Darwin, believed in special creation and that all species were unchanged. George-Louis Leclerc was one of the first naturalist that questioned this belief. He proposed in his 44 volume natural history book that species evolve due to environmental influences. Erasmus Darwin

832-518: A faster rate than other species. Amphibians spend parts of their time in the water and on land, making them susceptible to changes in both environments. They also have very permeable skin that allows them to breath and intake water, which means they also take any air or water-soluble pollutants in as well. Birds often cover a wide range in habitat types annually, and also generally revisit the same nesting site each year. This makes it easier for researchers to track ecological effects at both an individual and

936-413: A generation of evolutionary biologists. Current research in evolutionary biology covers diverse topics and incorporates ideas from diverse areas, such as molecular genetics and computer science . First, some fields of evolutionary research try to explain phenomena that were poorly accounted for in the modern evolutionary synthesis . These include speciation , the evolution of sexual reproduction ,

1040-440: A group of leading university and zoo researchers and conservationists including Kurt Benirschke , Sir Otto Frankel , Thomas Lovejoy , and Jared Diamond . The meeting was prompted due to concern over tropical deforestation, disappearing species, and eroding genetic diversity within species. The conference and proceedings that resulted sought to initiate the bridging of a gap between theory in ecology and evolutionary genetics on

1144-434: A more natural environment became clear. Peter Chalmers Mitchell (ZSL Secretary 1903–35) conceived the vision of a new park no more than 70 miles (110 km) away from London and thus accessible to the public, and at least 200 acres (0.81 km) in extent. In 1926, profiting from the agricultural depression, the ideal place was found: Hall Farm, near Whipsnade village , was derelict, and held almost 600 acres (2.4 km) on

1248-517: A multitude of other variables such as loss of biodiversity as a function of the rate of habitat loss and site occupancy to obtain such estimates. The Theory of Island Biogeography is possibly the most significant contribution toward the scientific understanding of both the process and how to measure the rate of species extinction. The current background extinction rate is estimated to be one species every few years. Actual extinction rates are estimated to be orders of magnitudes higher. While this

1352-458: A population level for the species. Many conservation researchers believe that having a long-term ecological monitoring program should be a priority for conservation projects, protected areas, and regions where environmental harm mitigation is used. Conservation biologists are interdisciplinary researchers that practice ethics in the biological and social sciences. Chan states that conservationists must advocate for biodiversity and can do so in

1456-435: A population, the genetic variations affect the phenotypes (physical characteristics) of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed on to their offspring . Some examples of evolution in species over many generations are the peppered moth and flightless birds . In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called

1560-404: A population. It has a much stronger effect on small populations than large ones. Gene flow : Gene flow is the transfer of genetic material from the gene pool of one population to another. In a population, migration occurs from one species to another, resulting in the change of allele frequency. Natural selection : The survival and reproductive rate of a species depends on the adaptability of

1664-415: A protected existence that halts interference from the humans. In this regard, conservationists differ from preservationists in the social dimension, as conservation biology engages society and seeks equitable solutions for both society and ecosystems. Some preservationists emphasize the potential of biodiversity in a world without humans. Ecological monitoring is the systematic collection of data relevant to

1768-466: A recent phenomenon. Natural resource conservation, however, has a history that extends prior to the age of conservation. Resource ethics grew out of necessity through direct relations with nature. Regulation or communal restraint became necessary to prevent selfish motives from taking more than could be locally sustained, therefore compromising the long-term supply for the rest of the community. This social dilemma with respect to natural resource management

1872-492: A scientifically ethical manner by not promoting simultaneous advocacy against other competing values. Evolutionary biology Evolutionary biology is the subfield of biology that studies the evolutionary processes ( natural selection , common descent , speciation ) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. In

1976-470: A whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering. Extinction rates are measured in a variety of ways. Conservation biologists measure and apply statistical measures of fossil records , rates of habitat loss , and

2080-646: Is a registered charity under English law. Under the Crown Estate Act 1961 , the ZSL had a maximum lease length of 60 years from the Crown Estate , but this was changed to 150 years by the Zoological Society of London (Leases) Act 2024 (c. 20). The Institute of Zoology is the scientific research division of the ZSL. It is a government-funded research institute, which specialises in scientific issues relevant to

2184-496: Is a change in the DNA sequence inside a gene or a chromosome of an organism. Most mutations are deleterious, or neutral; i.e. they can neither harm nor benefit, but can also be beneficial sometimes. Genetic drift : Genetic drift is a variational process, it happens as a result of the sampling errors from one generation to another generation where a random event that happens by chance in nature changes or influences allele frequency within

2288-412: Is also an example of resistance that will cause the bacteria against which the antibiotic is being taken to evolve and continue to spread in the body. When the full dosage of the medication does not enter the body and perform its proper job, the bacteria that survive the initial dosage will continue to reproduce. This can make for another bout of sickness later on that will be more difficult to cure because

2392-537: Is an effective way to seek and identify efficient and effective types of reserve design to capture or sustain the highest priority biodiversity values and to work with communities in support of local ecosystems. Margules and Pressey identify six interlinked stages in the systematic planning approach: Conservation biologists regularly prepare detailed conservation plans for grant proposals or to effectively coordinate their plan of action and to identify best management practices (e.g. ). Systematic strategies generally employ

2496-490: Is based on a new philosophy or leadership theory steering away from historical notions of power, authority, and dominance. Adaptive conservation leadership is reflective and more equitable as it applies to any member of society who can mobilize others toward meaningful change using communication techniques that are inspiring, purposeful, and collegial. Adaptive conservation leadership and mentoring programs are being implemented by conservation biologists through organizations such as

2600-479: Is by perceived taxonomic group , with fields such as zoology , botany , and microbiology , reflecting what was once seen as the major divisions of life. A third way is by approaches, such as field biology, theoretical biology , experimental evolution , and paleontology. These alternative ways of dividing up the subject have been combined with evolutionary biology to create subfields like evolutionary ecology and evolutionary developmental biology . More recently,

2704-415: Is concerned with phenomena that affect the maintenance, loss, and restoration of biodiversity and the science of sustaining evolutionary processes that engender genetic , population , species , and ecosystem diversity. The concern stems from estimates suggesting that up to 50% of all species on the planet will disappear within the next 50 years, which will increase poverty and starvation, and will reset

2808-423: Is debate on which metrics that money, time and personnel should be dedicated to for the best chance of making a positive impact. One specific general discussion topic is whether monitoring should happen where there is little human impact (to understand a system that has not been degraded by humans), where there is human impact (so the effects from humans can be investigated), or where there is data deserts and little

2912-598: Is important, it's worth noting that there are no models in existence that account for the complexity of unpredictable factors like species movement, a non-analog climate, changing species interactions, evolutionary rates on finer time scales, and many other stochastic variables. The measure of ongoing species loss is made more complex by the fact that most of the Earth's species have not been described or evaluated. Estimates vary greatly on how many species actually exist (estimated range: 3,600,000–111,700,000) to how many have received

3016-436: Is known about the habitats' and communities' response to human perturbations . The concept of bioindicators / indicator species can be applied to ecological monitoring as a way to investigate how pollution is affecting an ecosystem. Species like amphibians and birds are highly susceptible to pollutants in their environment due to their behaviours and physiological features that cause them to absorb pollutants at

3120-563: Is now directed at urban conservation biology. The Society for Conservation Biology originated in 1985. By 1992, most of the countries of the world had become committed to the principles of conservation of biological diversity with the Convention on Biological Diversity ; subsequently many countries began programmes of Biodiversity Action Plans to identify and conserve threatened species within their borders, as well as protect associated habitats. The late 1990s saw increasing professionalism in

3224-490: Is now often considered a subdiscipline as well. The rapid decline of established biological systems around the world means that conservation biology is often referred to as a "Discipline with a deadline". Conservation biology is tied closely to ecology in researching the population ecology ( dispersal , migration , demographics , effective population size , inbreeding depression , and minimum population viability ) of rare or endangered species . Conservation biology

3328-953: Is often called the " Tragedy of the Commons ". From this principle, conservation biologists can trace communal resource based ethics throughout cultures as a solution to communal resource conflict. For example, the Alaskan Tlingit peoples and the Haida of the Pacific Northwest had resource boundaries, rules, and restrictions among clans with respect to the fishing of sockeye salmon . These rules were guided by clan elders who knew lifelong details of each river and stream they managed. There are numerous examples in history where cultures have followed rules, rituals, and organized practice with respect to communal natural resource management. The Mauryan emperor Ashoka around 250 BC issued edicts restricting

3432-660: Is particularly relevant to practitioners in that it has the potential to generate cause-and-effect relationships and reveal the factors that contribute to population declines. The Society for Conservation Biology is a global community of conservation professionals dedicated to advancing the science and practice of conserving biodiversity. Conservation biology as a discipline reaches beyond biology, into subjects such as philosophy , law , economics , humanities , arts , anthropology , and education . Within biology, conservation genetics and evolution are immense fields unto themselves, but these disciplines are of prime importance to

3536-513: Is similar to the medical profession advocating for healthy lifestyle options, both are beneficial to human well-being yet remain scientific in their approach. There is a movement in conservation biology suggesting a new form of leadership is needed to mobilize conservation biology into a more effective discipline that is able to communicate the full scope of the problem to society at large. The movement proposes an adaptive leadership approach that parallels an adaptive management approach. The concept

3640-437: Is that the classical population genetics that catalysed the modern evolutionary synthesis must be updated to take into account modern molecular knowledge. This requires a great deal of mathematical development to relate DNA sequence data to evolutionary theory as part of a theory of molecular evolution . For example, biologists try to infer which genes have been under strong selection by detecting selective sweeps . Fourth,

3744-493: Is the hard evidence it provides scientists to use for advising policy makers and funding bodies about conservation efforts. Not only is ecological monitoring data important for convincing politicians, funders, and the public why a conservation program is important to implement, but also to keep them convinced that a program should be continued to be supported. There is plenty of debate on how conservation resources can be used most efficiently; even within ecological monitoring, there

3848-520: Is the process in which related or distantly related organisms evolve similar characteristics independently. This type of evolution creates analogous structures which have a similar function, structure, or form between the two species. For example, sharks and dolphins look alike but they are not related. Likewise, birds, flying insects, and bats all have the ability to fly, but they are not related to each other. These similar traits tend to evolve from having similar environmental pressures. Divergent evolution

3952-428: Is the process of speciation. This can happen in several ways: The influence of two closely associated species is known as coevolution . When two or more species evolve in company with each other, one species adapts to changes in other species. This type of evolution often happens in species that have symbiotic relationships . For example, predator-prey coevolution, this is the most common type of co-evolution. In this,

4056-722: The Chiltern Hills . ZSL bought the farm in December 1926 for £13,480 12s 10d. In 1928 the first animals arrived at the new Whipsnade Park —two Amherst pheasants , a golden pheasant and five red jungle fowl . Others soon followed, including muntjac deer , llamas , wombats and skunks . In 1931 Whipsnade Park was opened to the public as the world's first open zoological park. In 1960–61, Lord Zuckerman , then Secretary of ZSL, raised funds from two medical foundations to found laboratories as an Institute of Zoology where scientists would be employed by ZSL and undertake research. The Society

4160-590: The International Zoo Yearbook and Remote Sensing in Ecology and Conservation . The society administers the following award programmes: Individuals can be elected Fellows of the Zoological Society of London and therefore granted the post-nominal letters FZS . Living Honorary ZSL Fellows ( Hon. FZS ) comprise: The council is the governing body of the ZSL. There are 15 council members, led by

4264-655: The Marquess of Lansdowne , Lord Auckland , Sir Humphry Davy , Robert Peel , Joseph Sabine , Nicholas Aylward Vigors along with various other nobility, clergy, and naturalists. Raffles was the first chairman and president, but died after only a few months in office, in July 1826. He was succeeded by the Marquess of Lansdowne who supervised the building of the first animal houses, a parcel of land in Regent's Park having already been obtained from

4368-480: The ecology of a species or habitat at repeating intervals with defined methods. Long-term monitoring for environmental and ecological metrics is an important part of any successful conservation initiative. Unfortunately, long-term data for many species and habitats is not available in many cases. A lack of historical data on species populations , habitats, and ecosystems means that any current or future conservation work will have to make assumptions to determine if

4472-441: The environment , that there was a civic duty to maintain the environment for future generations, and that scientific, empirically based methods should be applied to ensure this duty was carried out. Sir James Ranald Martin was prominent in promoting this ideology, publishing many medico-topographical reports that demonstrated the scale of damage wrought through large-scale deforestation and desiccation, and lobbying extensively for

4576-434: The modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics , and paleontology . The investigational range of current research has widened to encompass the genetic architecture of adaptation , molecular evolution , and the different forces that contribute to evolution, such as sexual selection , genetic drift , and biogeography . Moreover,

4680-721: The mountain gorilla and establish Albert National Park (since renamed Virunga National Park ) in what is now Democratic Republic of Congo . By the 1970s, led primarily by work in the United States under the Endangered Species Act along with the Species at Risk Act (SARA) of Canada, Biodiversity Action Plans developed in Australia , Sweden , the United Kingdom , hundreds of species specific protection plans ensued. Notably

4784-594: The Aldo Leopold Leadership Program. Conservation may be classified as either in-situ conservation , which is protecting an endangered species in its natural habitat , or ex-situ conservation , which occurs outside the natural habitat. In-situ conservation involves protecting or restoring the habitat. Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks , in circumstances where viable populations may not be present in

4888-611: The Crown at the inaugural meeting. It received a royal charter from George IV on 27 March 1829. The purpose of the society was to create a collection of animals for study at leisure, an associated museum and library. In April 1828, the Zoological Gardens were opened to members. In 1831 William IV presented the Royal Menagerie to the Zoological Society, and in 1847 the public was admitted to aid funding, and Londoners soon christened

4992-530: The Endangered Species Act (1966) and National Environmental Policy Act (1970), which together injected major funding and protection measures to large-scale habitat protection and threatened species research. Other conservation developments, however, have taken hold throughout the world. India, for example, passed the Wildlife Protection Act of 1972 . In 1980, a significant development was

5096-605: The Mesozoic and Cenozoic eras (between 299 million to 12,000 years ago). Other fields related to generic exploration of evolution ("what happened and when?" ) include systematics and phylogenetics . Third, the modern evolutionary synthesis was devised at a time when nobody understood the molecular basis of genes. Today, evolutionary biologists try to determine the genetic architecture of interesting evolutionary phenomena such as adaptation and speciation. They seek answers to questions such as how many genes are involved, how large are

5200-623: The RSPB. The National Trust formed in 1895 with the manifesto to "...promote the permanent preservation, for the benefit of the nation, of lands, ... to preserve (so far practicable) their natural aspect." In May 1912, a month after the Titanic sank, banker and expert naturalist Charles Rothschild held a meeting at the Natural History Museum in London to discuss his idea for a new organisation to save

5304-542: The United Nations acted to conserve sites of outstanding cultural or natural importance to the common heritage of mankind. The programme was adopted by the General Conference of UNESCO in 1972. As of 2006, a total of 830 sites are listed: 644 cultural, 162 natural. The first country to pursue aggressive biological conservation through national legislation was the United States, which passed back to back legislation in

5408-437: The Zoological Gardens the " Zoo ". London Zoo soon had the most extensive collection of animals in the world. A History of the ZSL , written by Henry Scherren (FZS), was published in 1905. The History was criticised as inadequately researched by Peter Chalmers Mitchell in 1929; both histories were labelled inaccurate by John Bastin in 1970. As the twentieth century began, the need to maintain and research large animals in

5512-669: The affairs of the ZSL. The secretaries and their dates in office are: Animal conservation The conservation ethic is based on the findings of conservation biology. The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with

5616-467: The area covered due to unplanned urbanization activities. Then they plant the new saplings of same tree families of that existing forest in the areas where the old forest has been lost and also plant those saplings to the barren areas connected to the forest. This maintains the density and area covered by the forest. Also, non-interference may be used, which is termed a preservationist method. Preservationists advocate for giving areas of nature and species

5720-434: The bacteria involved will be resistant to the first medication used. Taking the full course of medicine that is prescribed is a vital step in avoiding antibiotic resistance. Individuals with chronic illnesses, especially those that can recur throughout a lifetime, are at greater risk of antibiotic resistance than others. This is because overuse of a drug or too high of a dosage can cause a patient's immune system to weaken and

5824-862: The best places for wildlife in the British Isles. This meeting led to the formation of the Society for the Promotion of Nature Reserves, which later became the Wildlife Trusts . In the United States , the Forest Reserve Act of 1891 gave the President power to set aside forest reserves from the land in the public domain. John Muir founded the Sierra Club in 1892, and the New York Zoological Society

5928-518: The biodiversity crisis through conservation action plans that direct research, monitoring, and education programs that engage concerns at local through global scales. There is increasing recognition that conservation is not just about what is achieved but how it is done. The conservation of natural resources is the fundamental problem. Unless we solve that problem, it will avail us little to solve all others. – Theodore Roosevelt Conscious efforts to conserve and protect global biodiversity are

6032-421: The broad range of taxa (i.e. including microbes, plants, and animals). Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales, and conservation includes the development and refinement of strategies to rebuild populations, restore ecosystems, inform conservation policy, generate decision-support tools, and manage natural resources. Conservation physiology

6136-500: The changes in the environment, this makes the organism suitable to its habitat. This change increases the chances of survival and reproduction of the organism (this can be referred to as an organism's fitness ). For example, Darwin's Finches on Galapagos island developed different shaped beaks in order to survive for a long time. Adaptive evolution can also be convergent evolution if two distantly related species live in similar environments facing similar pressures. Convergent evolution

6240-495: The conservation of species and their habitats. The Institute of Zoology focuses its research on five areas: evolutionary biology , genetics , ecology , reproductive biology and wildlife epidemiology. The Institute of Zoology was graded 4 in the 1997–2001 UK Research Assessment Exercise, and publishes reports annually. From the late 1980s the Institute of Zoology had been affiliated to the University of London . However, in 2000 this

6344-434: The course of evolution on this planet. Researchers acknowledge that projections are difficult, given the unknown potential impacts of many variables, including species introduction to new biogeographical settings and a non-analog climate. Conservation biologists research and educate on the trends and process of biodiversity loss , species extinctions , and the negative effect these are having on our capabilities to sustain

SECTION 60

#1732852123143

6448-662: The early 19th century biogeography was ignited through the efforts of Alexander von Humboldt , Charles Lyell and Charles Darwin . The 19th-century fascination with natural history engendered a fervor to be the first to collect rare specimens with the goal of doing so before they became extinct by other such collectors. Although the work of many 18th and 19th century naturalists were to inspire nature enthusiasts and conservation organizations , their writings, by modern standards, showed insensitivity towards conservation as they would kill hundreds of specimens for their collections. The modern roots of conservation biology can be found in

6552-454: The effects of each gene, how interdependent are the effects of different genes, what do the genes do, and what changes happen to them (e.g., point mutations vs. gene duplication or even genome duplication ). They try to reconcile the high heritability seen in twin studies with the difficulty in finding which genes are responsible for this heritability using genome-wide association studies . One challenge in studying genetic architecture

6656-611: The emergence of the urban conservation movement. A local organization was established in Birmingham , UK, a development followed in rapid succession in cities across the UK, then overseas. Although perceived as a grassroots movement , its early development was driven by academic research into urban wildlife. Initially perceived as radical, the movement's view of conservation being inextricably linked with other human activity has now become mainstream in conservation thought. Considerable research effort

6760-409: The evolution of cooperation , the evolution of ageing , and evolvability . Second, some evolutionary biologists ask the most straightforward evolutionary question: "what happened and when?". This includes fields such as paleobiology , where paleobiologists and evolutionary biologists, including Thomas Halliday and Anjali Goswami, studied the evolution of early mammals going far back in time during

6864-712: The first conservation societies was the Royal Society for the Protection of Birds , founded in 1889 in Manchester as a protest group campaigning against the use of great crested grebe and kittiwake skins and feathers in fur clothing . Originally known as "the Plumage League", the group gained popularity and eventually amalgamated with the Fur and Feather League in Croydon, and formed

6968-445: The illness will evolve and grow stronger. For example, cancer patients will need a stronger and stronger dosage of medication because of their low functioning immune system. Some scientific journals specialise exclusively in evolutionary biology as a whole, including the journals Evolution , Journal of Evolutionary Biology , and BMC Evolutionary Biology . Some journals cover sub-specialties within evolutionary biology, such as

7072-435: The immune system. Drug resistance also causes many problems for patients such as a worsening sickness or the sickness can mutate into something that can no longer be cured with medication. Without the proper medicine, a sickness can be the death of a patient. If their body has resistance to a certain number of drugs, then the right medicine will be harder and harder to find. Not completing the prescribed full course of antibiotic

7176-475: The institutionalization of forest conservation activities in British India through the establishment of Forest Departments . The Madras Board of Revenue started local conservation efforts in 1842, headed by Alexander Gibson , a professional botanist who systematically adopted a forest conservation program based on scientific principles. This was the first case of state conservation management of forests in

7280-535: The journals Systematic Biology , Molecular Biology and Evolution and its sister journal Genome Biology and Evolution , and Cladistics . Other journals combine aspects of evolutionary biology with other related fields. For example, Molecular Ecology , Proceedings of the Royal Society of London Series B , The American Naturalist and Theoretical Population Biology have overlap with ecology and other aspects of organismal biology. Overlap with ecology

7384-486: The kind of worm itself. Other structures like the development of Hox genes and sensory organs such as eyes can also be traced with this practice. Phylogenetic Trees are representations of genetic lineage. They are figures that show how related species are to one another. They formed by analyzing the physical traits as well as the similarities of the DNA between species. Then by using a molecular clock scientists can estimate when

7488-549: The late 18th-century Enlightenment period particularly in England and Scotland . Thinkers including Lord Monboddo described the importance of "preserving nature"; much of this early emphasis had its origins in Christian theology . Scientific conservation principles were first practically applied to the forests of British India . The conservation ethic that began to evolve included three core principles: that human activity damaged

7592-457: The management, mainly for economic reasons, of such natural resources as timber , fish, game, topsoil , pastureland , and minerals. In addition it referred to the preservation of forests ( forestry ), wildlife ( wildlife refuge ), parkland, wilderness , and watersheds . This period also saw the passage of the first conservation legislation and the establishment of the first nature conservation societies. The Sea Birds Preservation Act of 1869

7696-646: The merge between biological science and applied sciences gave birth to new fields that are extensions of evolutionary biology, including evolutionary robotics , engineering , algorithms , economics , and architecture. The basic mechanisms of evolution are applied directly or indirectly to come up with novel designs or solve problems that are difficult to solve otherwise. The research generated in these applied fields, contribute towards progress, especially from work on evolution in computer science and engineering fields such as mechanical engineering. Adaptive evolution relates to evolutionary changes that happen due to

7800-423: The metric must be able to capture the trend of the population or habitat as a whole. Long-term monitoring can include the continued measuring of many biological, ecological, and environmental metrics including annual breeding success, population size estimates, water quality, biodiversity (which can be measured in many way, i.e. Shannon Index ), and many other methods. When determining which metrics to monitor for

7904-602: The mid-20th century, efforts arose to target individual species for conservation, notably efforts in big cat conservation in South America led by the New York Zoological Society. In the early 20th century the New York Zoological Society was instrumental in developing concepts of establishing preserves for particular species and conducting the necessary conservation studies to determine the suitability of locations that are most appropriate as conservation priorities;

8008-479: The modern discipline of evolutionary biology. Theodosius Dobzhansky and E. B. Ford established an empirical research programme. Ronald Fisher , Sewall Wright , and J. B. S. Haldane created a sound theoretical framework. Ernst Mayr in systematics , George Gaylord Simpson in paleontology and G. Ledyard Stebbins in botany helped to form the modern synthesis. James Crow , Richard Lewontin , Dan Hartl , Marcus Feldman , and Brian Charlesworth trained

8112-895: The modern evolutionary synthesis involved agreement about which forces contribute to evolution, but not about their relative importance. Current research seeks to determine this. Evolutionary forces include natural selection , sexual selection , genetic drift , genetic draft , developmental constraints, mutation bias and biogeography . This evolutionary approach is key to much current research in organismal biology and ecology, such as life history theory . Annotation of genes and their function relies heavily on comparative approaches. The field of evolutionary developmental biology ("evo-devo") investigates how developmental processes work, and compares them in different organisms to determine how they evolved. Many physicians do not have enough background in evolutionary biology, making it difficult to use it in modern medicine. However, there are efforts to gain

8216-581: The movement toward wildlife conservation . In the 21st century professional conservation officers have begun to collaborate with indigenous communities for protecting wildlife in Canada. Some conservation efforts are yet to fully take hold due to ecological neglect. For example in the USA, 21st century bowfishing of native fishes, which amounts to killing wild animals for recreation and disposing of them immediately afterwards, remains unregulated and unmanaged. In

8320-456: The natural habitat. The conservation of habitats like forest, water or soil in its natural state is crucial for any species depending in it to thrive. Instead of making the whole new environment looking alike the original habitat of wild animals is less effective than preserving the original habitats. An approach in Nepal named reforestation campaign has helped increase the density and area covered by

8424-480: The newer field of evolutionary developmental biology ("evo-devo") investigates how embryogenesis is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study covered by the earlier evolutionary synthesis. Evolution is the central unifying concept in biology. Biology can be divided into various ways. One way is by the level of biological organization , from molecular to cell , organism to population . Another way

8528-407: The older departments of botany and zoology . Palaeontology is often grouped with earth science . Microbiology too is becoming an evolutionary discipline now that microbial physiology and genomics are better understood. The quick generation time of bacteria and viruses such as bacteriophages makes it possible to explore evolutionary questions. Many biologists have contributed to shaping

8632-528: The one hand and conservation policy and practice on the other. Conservation biology and the concept of biological diversity ( biodiversity ) emerged together, helping crystallize the modern era of conservation science and policy . The inherent multidisciplinary basis for conservation biology has led to new subdisciplines including conservation social science, conservation behavior and conservation physiology. It stimulated further development of conservation genetics which Otto Frankel had originated first but

8736-418: The original forests which proved to be better than creating entirely new environment after original one is let to lost. Old Forests Store More Carbon than Young Ones as proved by latest researches, so it is more crucial to protect the old ones. The reforestation campaign launched by Himalayan Adventure Therapy in Nepal basically visits the old forests in periodic basis which are vulnerable to loss of density and

8840-432: The phylogenetic process is what allows for this kind of understanding of biology to be possible. By looking at different processes during development, and going through the evolutionary tree, one can determine at which point a specific structure came about. For example, the three germ layers can be observed to not be present in cnidarians and ctenophores, which instead present in worms, being more or less developed depending on

8944-445: The practice and profession of conservation biology. Conservationists introduce bias when they support policies using qualitative description, such as habitat degradation , or healthy ecosystems . Conservation biologists advocate for reasoned and sensible management of natural resources and do so with a disclosed combination of science , reason , logic , and values in their conservation management plans. This sort of advocacy

9048-579: The predator must evolve to become a more effective hunter because there is a selective pressure on the prey to steer clear of capture. The prey in turn need to develop better survival strategies. The Red Queen hypothesis is an example of predator-prey interations. The relationship between pollinating insects like bees and flowering plants, herbivores and plants, are also some common examples of diffuse or guild coevolution. The mechanisms of evolution focus mainly on mutation, genetic drift, gene flow, non-random mating, and natural selection. Mutation : Mutation

9152-473: The president and served by the secretary and treasurer. Council members are the trustees of the society and serve for up to five years at a time. The Presidency is a voluntary position, with the role of leading the ZSL Council. The Society's Presidents and their dates in office are: The post of secretary is honorary and under the society's constitution carries the responsibility for the day-to-day management of

9256-400: The rich, soft soil has been carried off and only the bare framework of the district left." In the bible, through Moses, God commanded to let the land rest from cultivation every seventh year. Before the 18th century, however, much of European culture considered it a pagan view to admire nature. Wilderness was denigrated while agricultural development was praised. However, as early as AD 680

9360-674: The sector, with the maturing of organisations such as the Institute of Ecology and Environmental Management and the Society for the Environment . Since 2000, the concept of landscape scale conservation has risen to prominence, with less emphasis being given to single-species or even single-habitat focused actions. Instead an ecosystem approach is advocated by most mainstream conservationists, although concerns have been expressed by those working to protect some high-profile species. Ecology has clarified

9464-546: The services of Geographic Information Systems to assist in the decision-making process. The SLOSS debate is often considered in planning. Conservation physiology was defined by Steven J. Cooke and colleagues as: An integrative scientific discipline applying physiological concepts, tools, and knowledge to characterizing biological diversity and its ecological implications; understanding and predicting how organisms, populations, and ecosystems respond to environmental change and stressors; and solving conservation problems across

9568-456: The slaughter of animals and certain kinds of birds, as well as opened veterinary clinics. Conservation ethics are also found in early religious and philosophical writings. There are examples in the Tao , Shinto , Hindu , Islamic and Buddhist traditions. In Greek philosophy, Plato lamented about pasture land degradation : "What is left now is, so to say, the skeleton of a body wasted by disease;

9672-420: The species diverged. An example of a phylogeny would be the tree of life. Genes that have shared ancestry are homologs. If a speciation event occurs and one gene ends up in two different species the genes are now orthologous. If a gene is duplicated within the a singular species then it is a paralog. A molecular clock can be used to estimate when these events occurred. The idea of evolution by natural selection

9776-468: The species to their environment. This process is called natural selection . Some species with certain traits in a population have higher survival and reproductive rate than others ( fitness ), and they pass on these genetic features to their offsprings. In evolutionary developmental biology, scientists look at how the different processes in development play a role in how a specific organism reaches its current body plan. The genetic regulation of ontogeny and

9880-524: The well-being of human society. Conservation biologists work in the field and office, in government, universities, non-profit organizations and industry. The topics of their research are diverse, because this is an interdisciplinary network with professional alliances in the biological as well as social sciences. Those dedicated to the cause and profession advocate for a global response to the current biodiversity crisis based on morals , ethics , and scientific reason. Organizations and citizens are responding to

9984-403: The work is having any effect on the population or ecosystem health. Ecological monitoring can provide early warning signals of deleterious effects (from human activities or natural changes in an environment) on an ecosystem and its species. In order for signs of negative trends in ecosystem or species health to be detected, monitoring methods must be carried out at appropriate time intervals, and

10088-458: The work of Henry Fairfield Osborn Jr., Carl E. Akeley , Archie Carr and his son Archie Carr III is notable in this era. Akeley for example, having led expeditions to the Virunga Mountains and observed the mountain gorilla in the wild, became convinced that the species and the area were conservation priorities. He was instrumental in persuading Albert I of Belgium to act in defense of

10192-420: The workings of the biosphere ; i.e., the complex interrelationships among humans, other species, and the physical environment. The burgeoning human population and associated agriculture , industry , and the ensuing pollution, have demonstrated how easily ecological relationships can be disrupted. The last word in ignorance is the man who says of an animal or plant: "What good is it?" If the land mechanism as

10296-403: The world. Governor-General Lord Dalhousie introduced the first permanent and large-scale forest conservation program in the world in 1855, a model that soon spread to other colonies , as well the United States, where Yellowstone National Park was opened in 1872 as the world's first national park. The term conservation came into widespread use in the late 19th century and referred to

10400-410: Was also a naturalist who also suggested that species evolved. Erasmus Darwin noted that some species have vestigial structures which are anatomical structures that have no apparent function in the species currently but would have been useful for the species' ancestors. The thinking of these early 18th century naturalists helped to change the mindset and thinking of the early 19th century naturalists. By

10504-514: Was passed in Britain as the first nature protection law in the world after extensive lobbying from the Association for the Protection of Seabirds and the respected ornithologist Alfred Newton . Newton was also instrumental in the passage of the first Game laws from 1872, which protected animals during their breeding season so as to prevent the stock from being brought close to extinction. One of

10608-429: Was proposed by Charles Darwin in 1859, but evolutionary biology, as an academic discipline in its own right, emerged during the period of the modern synthesis in the 1930s and 1940s. It was not until the 1980s that many universities had departments of evolutionary biology. In the United States, many universities have created departments of molecular and cell biology or ecology and evolutionary biology , in place of

10712-744: Was replaced with a partnership with the University of Cambridge. ZSL runs London Zoo , Whipsnade Zoo and had planned to open an aquarium, Biota! . The society published the Zoological Record ( ZR ) from 1864 to 1980, when the ZR was transferred to BIOSIS . The Society has published the Proceedings of the Zoological Society of London , now called the Journal of Zoology , since 1830. Since 1998 it has also published Animal Conservation . Other publications include

10816-517: Was set up in 1895. A series of national forests and preserves were established by Theodore Roosevelt from 1901 to 1909. The 1916 National Parks Act, included a 'use without impairment' clause, sought by John Muir, which eventually resulted in the removal of a proposal to build a dam in Dinosaur National Monument in 1959. In the 20th century, Canadian civil servants, including Charles Gordon Hewitt and James Harkin , spearheaded
