Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game ). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including recognition .

Three levels of end-state economic competition have been classified: In addition, companies compete for financing on the capital markets (equity or debt) in order to generate the necessary cash for their operations. Investor typically consider alternative investment opportunities given their risk profile, and not only look at companies just competing on product ( direct competitors ). Enlarging
375-410: A ball, or defending territory on a playing field is not an innate biological factor in humans. Athletes in sports such as gymnastics and competitive diving compete against each other in order to come closest to a conceptual ideal of a perfect performance, which incorporates measurable criteria and standards which are translated into numerical ratings and scores by appointed judges. Sports competition
500-476: A combination of both. People that enjoy entering competitions are known as compers. Many philosophers and psychologists have identified a trait in most living organisms which can drive the particular organism to compete. This trait, called competitiveness, is viewed as having a high adaptive value , which coexists along with the urge for survival. Competitiveness, or the inclination to compete, though, has become synonymous with aggressiveness and ambition in
625-481: A decision. Sigmund Freud explained competition as a primal dilemma in which all infants find themselves. The infant competes with other family members for the attention and affection of the parent of the opposite sex or the primary caregiving parent. During this time, a boy develops a deep fear that the father (the son's prime rival) will punish him for these feelings of desire for the mother, by castrating him. Girls develop penis envy towards all males. The girl's envy
750-432: A deliberate system of internal brand-versus-brand rivalry. The company was organized around different brands , with each brand allocated resources, including a dedicated group of employees willing to champion the brand. Each brand manager was given responsibility for the success or failure of the brand, and compensated accordingly. Most businesses also encourage competition between individual employees. An example of this
875-460: A dramatic effect on community structure. Hunting of sea otters, for example, is thought to have led indirectly to the extinction of the Steller's sea cow ( Hydrodamalis gigas ). While the keystone species concept has been used extensively as a conservation tool, it has been criticized for being poorly defined from an operational stance. It is difficult to experimentally determine what species may hold
1000-428: A dramatic impact on the ecology of individual species or whole ecosystems. For instance, the replacement of an ant species by another (invasive) ant species has been shown to affect how elephants reduce tree cover and thus the predation of lions on zebras . A trophic level (from Greek troph , τροφή, trophē, meaning "food" or "feeding") is "a group of organisms acquiring a considerable majority of its energy from
1125-412: A flattened body relative to the main populations that live in open savanna. The population that lives in an isolated rock outcrop hides in crevasses where its flattened body offers a selective advantage. Habitat shifts also occur in the developmental life history of amphibians, and in insects that transition from aquatic to terrestrial habitats. Biotope and habitat are sometimes used interchangeably, but
1250-399: A game of basketball , two teams compete against one another to determine who can score the most points. When there is no set reward for the winning team, many players gain a sense of pride . In addition, extrinsic rewards may also be given. Athletes, besides competing against other humans, also compete against nature in sports such as whitewater kayaking or mountaineering , where the goal
1375-581: A given market. The two academic bodies of thought on the assessment of competitiveness are the Structure Conduct Performance Paradigm and the more contemporary New Empirical Industrial Organisation model. Predicting changes in the competitiveness of business sectors is becoming an integral and explicit step in public policymaking. Within capitalist economic systems, the drive of enterprises is to maintain and improve their own competitiveness. One-upmanship , also called "one-upsmanship",

Compared to their counterparts who are low in agency, these students are more likely to be flexible, adaptable and creative as adults. Merriam-Webster gives as one definition of competition (relating to business ) as "[...] rivalry: such as [...] the effort of two or more parties acting independently to secure
1625-612: A higher one." Small scale patterns do not necessarily explain large scale phenomena, otherwise captured in the expression (coined by Aristotle) 'the sum is greater than the parts'. "Complexity in ecology is of at least six distinct types: spatial, temporal, structural, process, behavioral, and geometric." From these principles, ecologists have identified emergent and self-organizing phenomena that operate at different environmental scales of influence, ranging from molecular to planetary, and these require different explanations at each integrative level . Ecological complexity relates to
1750-444: A keystone role in each ecosystem. Furthermore, food web theory suggests that keystone species may not be common, so it is unclear how generally the keystone species model can be applied. Complexity is understood as a large computational effort needed to piece together numerous interacting parts exceeding the iterative memory capacity of the human mind. Global patterns of biological diversity are complex. This biocomplexity stems from
1875-408: A keystone species can result in a community collapse just as the removal of the keystone in an arch can result in the arch's loss of stability. Sea otters ( Enhydra lutris ) are commonly cited as an example of a keystone species because they limit the density of sea urchins that feed on kelp . If sea otters are removed from the system, the urchins graze until the kelp beds disappear, and this has
2000-737: A legacy niche that was constructed before their time. Biomes are larger units of organization that categorize regions of the Earth's ecosystems, mainly according to the structure and composition of vegetation. There are different methods to define the continental boundaries of biomes dominated by different functional types of vegetative communities that are limited in distribution by climate, precipitation, weather, and other environmental variables. Biomes include tropical rainforest , temperate broadleaf and mixed forest , temperate deciduous forest , taiga , tundra , hot desert , and polar desert . Other researchers have recently categorized other biomes, such as
2125-439: A linear successional route, changes might occur quickly or slowly over thousands of years before specific forest successional stages are brought about by biological processes. An ecosystem's area can vary greatly, from tiny to vast. A single tree is of little consequence to the classification of a forest ecosystem, but is critically relevant to organisms living in and on it. Several generations of an aphid population can exist over
2250-439: A macroscopic view of the system. While the notion of trophic levels provides insight into energy flow and top-down control within food webs, it is troubled by the prevalence of omnivory in real ecosystems. This has led some ecologists to "reiterate that the notion that species clearly aggregate into discrete, homogeneous trophic levels is fiction." Nonetheless, recent studies have shown that real trophic levels do exist, but "above

Margaret Heffernan 's study, A Bigger Prize , examines the perils and disadvantages of competition in (for example) biology, families, sport, education, commerce and
2500-516: A mix of herbivores and predators). Omnivores do not fit neatly into a functional category because they eat both plant and animal tissues. It has been suggested that omnivores have a greater functional influence as predators because compared to herbivores, they are relatively inefficient at grazing. Trophic levels are part of the holistic or complex systems view of ecosystems. Each trophic level contains unrelated species that are grouped together because they share common ecological functions, giving
2625-420: A new appreciation for the influence that organisms have on the ecosystem and evolutionary process. The term "niche construction" is more often used in reference to the under-appreciated feedback mechanisms of natural selection imparting forces on the abiotic niche. An example of natural selection through ecosystem engineering occurs in the nests of social insects , including ants, bees, wasps, and termites. There

Plant ecologists use pollen records that accumulate and stratify in wetlands to reconstruct the timing of plant migration and dispersal relative to historic and contemporary climates. These migration routes involved an expansion of the range as plant populations expanded from one area to another. There
2875-438: A population. However, competition among resources also has a strong tendency for diversification between members of the same species, resulting in coexistence of competitive and non-competitive strategies or cycles between low and high competitiveness. Third parties within a species often favour highly competitive strategies leading to species extinction when environmental conditions are harsh ( evolutionary suicide ). Competition
3000-401: A region), and sites are classed either as sources or sinks. A site is a generic term that refers to places where ecologists sample populations, such as ponds or defined sampling areas in a forest. Source patches are productive sites that generate a seasonal supply of juveniles that migrate to other patch locations. Sink patches are unproductive sites that only receive migrants; the population at
3125-517: A seasonal influx of new immigrants. A dynamic metapopulation structure evolves from year to year, where some patches are sinks in dry years and are sources when conditions are more favorable. Ecologists use a mixture of computer models and field studies to explain metapopulation structure. Community ecology examines how interactions among species and their environment affect the abundance, distribution and diversity of species within communities. Johnson & Stinchcomb (2007) Community ecology
3250-516: A significant role in natural selection . At shorter time scales, competition is also one of the most important factors controlling diversity in ecological communities, but at larger scales expansion and contraction of ecological space is a much larger factor than competition. This is illustrated by living plant communities where asymmetric competition and competitive dominance frequently occur. Multiple examples of symmetric and asymmetric competition also exist for animals. In Australia, New Zealand and

International competitiveness can be measured on several criteria but few are as flexible and versatile to be applied across levels as Trade Competitiveness Index (TCI) The tendency toward extreme, unhealthy competition has been termed hypercompetitiveness . This concept originated in Karen Horney 's theories on neurosis ; specifically,
3500-456: A species describes the environment over which a species is known to occur and the type of community that is formed as a result. More specifically, "habitats can be defined as regions in environmental space that are composed of multiple dimensions, each representing a biotic or abiotic environmental variable; that is, any component or characteristic of the environment related directly (e.g. forage biomass and quality) or indirectly (e.g. elevation) to
3625-402: A specific habitat, such as a cave or a pond, and principles gleaned from small-scale studies are extrapolated to larger systems. Feeding relations require extensive investigations, e.g. into the gut contents of organisms, which can be difficult to decipher, or stable isotopes can be used to trace the flow of nutrient diets and energy through a food web. Despite these limitations, food webs remain
3750-446: A valuable tool in understanding community ecosystems. Food webs illustrate important principles of ecology : some species have many weak feeding links (e.g., omnivores ) while some are more specialized with fewer stronger feeding links (e.g., primary predators ). Such linkages explain how ecological communities remain stable over time and eventually can illustrate a "complete" web of life. The disruption of food webs may have

Ecosystems, for example, contain abiotic resources and interacting life forms (i.e., individual organisms that aggregate into populations which aggregate into distinct ecological communities). Because ecosystems are dynamic and do not necessarily follow
4125-485: Is a central concept in the ecology of organisms and is sub-divided into the fundamental and the realized niche. The fundamental niche is the set of environmental conditions under which a species is able to persist. The realized niche is the set of environmental plus ecological conditions under which a species persists. The Hutchinsonian niche is defined more technically as a " Euclidean hyperspace whose dimensions are defined as environmental variables and whose size
4250-402: Is a contest between sales representatives. The sales representative with the highest sales (or the best improvement in sales) over a period of time would gain benefits from the employer. This is also known as intra-brand competition . Shalev and Asbjornsen found that success (i.e. the saving resulted) of reverse auctions correlated most closely with competition. The literature widely supported

An example is where you purchase goods or services and then given the chance to enter into the lottery and possibly win a prize. A trade promotion lottery can be called a lotto, competition, contest, sweepstake, or giveaway. Such competitions can be games of luck (randomly drawn) or skill (judged on an entry question or submission), or possibly

Biogeographical patterns and range distributions are explained or predicted through knowledge of a species' traits and niche requirements. Species have functional traits that are uniquely adapted to the ecological niche. A trait is a measurable property, phenotype , or characteristic of an organism that may influence its survival. Genes play an important role in

On a global scale, national education systems, intending to bring out the best in the next generation, encourage competitiveness among students through scholarships . Countries such as England and Singapore have special education programmes which cater for specialist students, prompting charges of academic elitism . Upon receipt of their academic results, students tend to compare their grades to see who

Balance of trade can be considered a crude, but widely used proxy for international competitiveness across levels: country , industry or even firm . “We share a common belief that innovation comes from the edges,” said Luisa Delgado, an SAP HR director, who noted
5000-445: Is also present between species ("interspecific"). When resources are limited, several species may depend on these resources. Thus, each of the species competes with the others to gain access to the resources. As a result, species less suited to compete for the resources may die out unless they adapt by character dislocation, for instance. According to evolutionary theory , this competition within and between species for resources plays

Originally, it mainly addressed zero-sum games , in which one person's gains result in losses for the other participants. Game theory is a major method used in mathematical economics and business for modeling competing behaviors of interacting agents . Applications include
6125-552: Is more efficient than perfect competition . Competition, according to the theory, causes commercial firms to develop new products, services and technologies, which would give consumers greater selection and better products. The greater selection typically causes lower prices for the products, compared to what the price would be if there was no competition ( monopoly ) or little competition ( oligopoly ). However, competition may also lead to wasted (duplicated) effort and to increased costs (and prices) in some circumstances. For example,

Community ecologists study the determinants of patterns and processes for two or more interacting species. Research in community ecology might measure species diversity in grasslands in relation to soil fertility. It might also include the analysis of predator-prey dynamics, competition among similar plant species, or mutualistic interactions between crabs and corals.

Commonly used types of data include life history , fecundity , and survivorship, and these are analyzed using mathematical techniques such as matrix algebra . The information
10250-589: The flux of energy and matter through an environment. Ecosystems have biophysical feedback mechanisms that moderate processes acting on living ( biotic ) and abiotic components of the planet. Ecosystems sustain life-supporting functions and provide ecosystem services like biomass production (food, fuel, fiber, and medicine), the regulation of climate , global biogeochemical cycles , water filtration , soil formation , erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value. The scope of ecology contains
10375-400: The former applies to a community's environment, whereas the latter applies to a species' environment. Definitions of the niche date back to 1917, but G. Evelyn Hutchinson made conceptual advances in 1957 by introducing a widely adopted definition: "the set of biotic and abiotic conditions in which a species is able to persist and maintain stable population sizes." The ecological niche
10500-544: The former relates only to the physical modifications of the habitat whereas the latter also considers the evolutionary implications of physical changes to the environment and the feedback this causes on the process of natural selection. Ecosystem engineers are defined as: "organisms that directly or indirectly modulate the availability of resources to other species, by causing physical state changes in biotic or abiotic materials. In so doing they modify, maintain and create habitats." The ecosystem engineering concept has stimulated
10625-518: The full ecological scope of biodiversity. Natural capital that supports populations is critical for maintaining ecosystem services and species migration (e.g., riverine fish runs and avian insect control) has been implicated as one mechanism by which those service losses are experienced. An understanding of biodiversity has practical applications for species and ecosystem-level conservation planners as they make management recommendations to consulting firms, governments, and industry. The habitat of
10750-414: The gamester. The principle being all life being a game, who understands that if you're not one-up, you're one-down. Potter's unprincipled principles apply to almost any possession, experience or situation, deriving maximum undeserved rewards and discomfitting the opposition. The 1960 film School for Scoundrels and its 2006 remake were satiric portrayals of how to use Potter's ideas. In that context,
10875-524: The harmful effects, stating "people feel that they are under a great deal of pressure. They feel that their main objective in life is to do better than other people. That is certainly what young people are being taught in school every day. And it's not a good basis for a society." However, other studies such as the Torrance Tests of Creative Thinking show that the effect of competition on students depends on each individual's level of agency . Students with
11000-408: The herbivore trophic level, food webs are better characterized as a tangled web of omnivores." A keystone species is a species that is connected to a disproportionately large number of other species in the food-web . Keystone species have lower levels of biomass in the trophic pyramid relative to the importance of their role. The many connections that a keystone species holds means that it maintains
11125-515: The highly aggressive personality type which is characterized as "moving against people". In her view, some people have a need to compete and win at all costs as a means of maintaining their self-worth . These individuals are likely to turn any activity into a competition, and they will feel threatened if they find themselves losing. Researchers have found that men and women who score high on the trait of hypercompetitiveness are more narcissistic and less psychologically healthy than those who score low on
11250-406: The human and oceanic microbiomes . To a microbe , the human body is a habitat and a landscape. Microbiomes were discovered largely through advances in molecular genetics , which have revealed a hidden richness of microbial diversity on the planet. The oceanic microbiome plays a significant role in the ecological biogeochemistry of the planet's oceans. The largest scale of ecological organization
11375-573: The ideal market model. Behind the theory lies the history, reaching back further than the Roman Empire . The business practices of market traders, guilds and governments have always been subject to scrutiny and sometimes to severe sanctions. Since the twentieth century, competition law has become global. The two largest, most organised and influential systems of competition regulation are United States antitrust law and European Community competition law . The respective national/international authorities,
11500-437: The importance of competition as the primary driver of reverse auctions success. Their findings appear to support that argument, as competition correlated strongly with the reverse auction success, as well as with the number of bidders. Business and economic competition in most countries is often limited or restricted. Competition often is subject to legal restrictions. For example, competition may be legally prohibited, as in
11625-586: The intense competition for the small number of top jobs in music and movie-acting leads many aspiring musicians and actors to make substantial investments in training which are not recouped, because only a fraction become successful. Critics have also argued that competition can be destabilizing, particularly competition between certain financial institutions. Experts have also questioned the constructiveness of competition in profitability. It has been argued that competition-oriented objectives are counterproductive to raising revenues and profitability because they limit
11750-404: The interplay among ecological processes that operate and influence patterns at different scales that grade into each other, such as transitional areas or ecotones spanning landscapes. Complexity stems from the interplay among levels of biological organization as energy, and matter is integrated into larger units that superimpose onto the smaller parts. "What were wholes on one level become parts on
11875-412: The interplay of development and environmental expression of traits. Resident species evolve traits that are fitted to the selection pressures of their local environment. This tends to afford them a competitive advantage and discourages similarly adapted species from having an overlapping geographic range. The competitive exclusion principle states that two species cannot coexist indefinitely by living off
12000-464: The investment universe to include indirect competitors leads to a broader peer universe of comparable, indirectly competing companies. Competition does not necessarily have to be between companies. For example, business writers sometimes refer to internal competition . This is competition within companies. The idea was first introduced by Alfred Sloan at General Motors in the 1920s. Sloan deliberately created areas of overlap between divisions of
12125-402: The latter focuses on materials and energy fluxes. System behaviors must first be arrayed into different levels of the organization. Behaviors corresponding to higher levels occur at slow rates. Conversely, lower organizational levels exhibit rapid rates. For example, individual tree leaves respond rapidly to momentary changes in light intensity, CO 2 concentration, and the like. The growth of
12250-424: The lifespan of a single leaf. Each of those aphids, in turn, supports diverse bacterial communities. The nature of connections in ecological communities cannot be explained by knowing the details of each species in isolation, because the emergent pattern is neither revealed nor predicted until the ecosystem is studied as an integrated whole. Some ecological principles, however, do exhibit collective properties where
12375-432: The lower adjacent level (according to ecological pyramids ) nearer the abiotic source." Links in food webs primarily connect feeding relations or trophism among species. Biodiversity within ecosystems can be organized into trophic pyramids, in which the vertical dimension represents feeding relations that become further removed from the base of the food chain up toward top predators, and the horizontal dimension represents
12500-558: The most various kinds and sizes. They form one category of the multitudinous physical systems of the universe, which range from the universe as a whole down to the atom. Tansley (1935) Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material). Ecosystem ecologists attempt to determine
12625-424: The natural urge of competition and its circumstances. They also study group dynamics , to detect how competition emerges and what its effects are. Sociologists , meanwhile, study the effects of competition on society as a whole. Additionally, anthropologists study the history and prehistory of competition in various cultures. They also investigate how competition manifested itself in various cultural settings in
12750-456: The nature of the unique physical environments that shapes the biodiversity within each. A more recent addition to ecosystem ecology are technoecosystems , which are affected by or primarily the result of human activity. A food web is the archetypal ecological network . Plants capture solar energy and use it to synthesize simple sugars during photosynthesis . As plants grow, they accumulate nutrients and are eaten by grazing herbivores , and
12875-573: The niche is called the ecotope , which is defined as the full range of environmental and biological variables affecting an entire species. Organisms are subject to environmental pressures, but they also modify their habitats. The regulatory feedback between organisms and their environment can affect conditions from local (e.g., a beaver pond ) to global scales, over time and even after death, such as decaying logs or silica skeleton deposits from marine organisms. The process and concept of ecosystem engineering are related to niche construction , but
13000-531: The number of nitrogen fixers , can lead to disproportionate, perhaps irreversible, changes in the system properties." Biodiversity refers to the variety of life and its processes. It includes the variety of living organisms, the genetic differences among them, the communities and ecosystems in which they occur, and the ecological and evolutionary processes that keep them functioning, yet ever-changing and adapting. Noss & Carpenter (1994) Biodiversity (an abbreviation of "biological diversity") describes
13125-399: The observed data. In these island models, the rate of population change is described by: where N is the total number of individuals in the population, b and d are the per capita rates of birth and death respectively, and r is the per capita rate of population change. Using these modeling techniques, Malthus' population principle of growth was later transformed into a model known as
13250-416: The options of strategies for firms as well as their ability to offer innovative responses to changes in the market. In addition, the strong desire to defeat rival firms with competitive prices has the strong possibility of causing price wars . Another distinction appearing in economics is that between competition as an end-state – as in the case of both perfect and imperfect competition – and competition as
13375-406: The organization and structure of entire communities. The loss of a keystone species results in a range of dramatic cascading effects (termed trophic cascades ) that alters trophic dynamics, other food web connections, and can cause the extinction of other species. The term keystone species was coined by Robert Paine in 1969 and is a reference to the keystone architectural feature as the removal of
13500-918: The other parties for laws , funding and power . Finally, competition also exists between governments . Each country or nationality struggles for world dominance, power, or military strength. For example, the United States competed against the Soviet Union in the Cold War for world power, and the two also struggled over the different types of government (in these cases representative democracy and communism ). The result of this type of competition often leads to worldwide tensions, and may sometimes erupt into warfare . While some sports and games (such as fishing or hiking ) have been viewed as primarily recreational, most sports are considered competitive. The majority involve competition between two or more persons (sometimes using horses or cars ). For example, in
13625-457: The past, and how competition has developed over time. Competition within, between, and among species is one of the most important forces in biology, especially in the field of ecology . Competition between members of a species ("intraspecific") for resources such as food , water , territory , and sunlight may result in an increase in the frequency of a variant of the species best suited for survival and reproduction until its fixation within
13750-415: The personal choice to have fewer tendencies toward egoism and selfishness. Competition is also found in politics . In democracies , a free and fair election is an electoral competition for an elected office. In other words, two or more candidates strive and compete against one another to attain a position of power. The winner gains the seat of the elected office for a predefined period of time, towards
13875-468: The published work of George Perkins Marsh ("Man and Nature"). Within an ecosystem, organisms are linked to the physical and biological components of their environment to which they are adapted. Ecosystems are complex adaptive systems where the interaction of life processes form self-organizing patterns across different scales of time and space. Ecosystems are broadly categorized as terrestrial , freshwater , atmospheric, or marine . Differences stem from
14000-502: The rate of change in population size ( d N ( t ) / d t {\displaystyle \mathrm {d} N(t)/\mathrm {d} t} ) will grow to approach equilibrium, where ( d N ( t ) / d t = 0 {\displaystyle \mathrm {d} N(t)/\mathrm {d} t=0} ), when the rates of increase and crowding are balanced, r / α {\displaystyle r/\alpha } . A common, analogous model fixes
14125-503: The same environment . Animals compete over water supplies, food, mates, and other biological resources . Humans usually compete for food and mates , though when these needs are met deep rivalries often arise over the pursuit of wealth , power, prestige, and fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economies and business, often associated with business competition as companies are in competition with at least one other firm over
14250-474: The same group of customers. Competition inside a company is usually stimulated with the larger purpose of meeting and reaching higher quality of services or improved products that the company may produce or develop. Competition is often considered to be the opposite of cooperation ; however, in the real world, mixtures of cooperation and competition are the norm. In economies, as the philosopher R. G. Collingwood argued "the presence of these two opposites together
14375-424: The same limiting resource ; one will always out-compete the other. When similarly adapted species overlap geographically, closer inspection reveals subtle ecological differences in their habitat or dietary requirements. Some models and empirical studies, however, suggest that disturbances can stabilize the co-evolution and shared niche occupancy of similar species inhabiting species-rich communities. The habitat plus
14500-399: The site will disappear unless rescued by an adjacent source patch or environmental conditions become more favorable. Metapopulation models examine patch dynamics over time to answer potential questions about spatial and demographic ecology. The ecology of metapopulations is a dynamic process of extinction and colonization. Small patches of lower quality (i.e., sinks) are maintained or rescued by
14625-524: The study of ecology into a conceptually manageable framework, the biological world is organized into a nested hierarchy , ranging in scale from genes , to cells , to tissues , to organs , to organisms , to species , to populations , to guilds , to communities , to ecosystems , to biomes , and up to the level of the biosphere . This framework forms a panarchy and exhibits non-linear behaviors; this means that "effect and cause are disproportionate, so that small changes to critical variables, such as
14750-432: The sum of the components explain the properties of the whole, such as birth rates of a population being equal to the sum of individual births over a designated time frame. The main subdisciplines of ecology, population (or community ) ecology and ecosystem ecology , exhibit a difference not only in scale but also in two contrasting paradigms in the field. The former focuses on organisms' distribution and abundance, while
14875-408: The term refers to a satiric course in the gambits required for the systematic and conscious practice of "creative intimidation", making one's associates feel inferior and thereby gaining the status of being "one-up" on them. Viewed seriously, it is a phenomenon of group dynamics that can have significant effects in the management field: for instance, manifesting in office politics . Competition

15125-496: The trait. Hypercompetitive individuals generally believe that winning is the only thing that matters. Ecology Ecology (from Ancient Greek οἶκος ( oîkos ) 'house' and -λογία ( -logía ) 'study of') is the natural science of the relationships among living organisms and their environment . Ecology considers organisms at the individual, population , community , ecosystem , and biosphere levels. Ecology overlaps with
15250-670: The tree responds more slowly and integrates these short-term changes. O'Neill et al. (1986) The scale of ecological dynamics can operate like a closed system, such as aphids migrating on a single tree, while at the same time remaining open about broader scale influences, such as atmosphere or climate. Hence, ecologists classify ecosystems hierarchically by analyzing data collected from finer scale units, such as vegetation associations , climate, and soil types , and integrate this information to identify emergent patterns of uniform organization and processes that operate on local to regional, landscape , and chronological scales. To structure
15375-415: The underlying causes of these fluxes. Research in ecosystem ecology might measure primary production (g C/m^2) in a wetland in relation to decomposition and consumption rates (g C/m^2/y). This requires an understanding of the community connections between plants (i.e., primary producers) and the decomposers (e.g., fungi and bacteria). The underlying concept of an ecosystem can be traced back to 1864 in
15500-439: The use of a location by the animal." For example, a habitat might be an aquatic or terrestrial environment that can be further categorized as a montane or alpine ecosystem. Habitat shifts provide important evidence of competition in nature where one population changes relative to the habitats that most other individuals of the species occupy. For example, one population of a species of tropical lizard ( Tropidurus hispidus ) has
15625-589: Was coined in 1866 by the German scientist Ernst Haeckel . The science of ecology as we know it today began with a group of American botanists in the 1890s. Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory . Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living ( abiotic ) components of their environment. Ecosystem processes, such as primary production , nutrient cycling , and niche construction , regulate
