  2. Ecological niche - Wikipedia

    en.wikipedia.org/wiki/Ecological_niche

    Ecological niche. The flightless dung beetle occupies an ecological niche: exploiting animal droppings as a food source. In ecology, a niche is the match of a species to a specific environmental condition. [1][2] It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when ...

  3. Niche construction - Wikipedia

    en.wikipedia.org/wiki/Niche_construction

    Niche construction. Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the ...

  4. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    v. t. e. Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία (-logía) 'study of') [A] is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels.

  5. Species distribution modelling - Wikipedia

    en.wikipedia.org/wiki/Species_Distribution_Modelling

    Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...

  6. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    Yellow adapts to a new niche restricted to the top and bottom and avoiding competition. In ecology, the competitive exclusion principle, [1] sometimes referred to as Gause's law, [2] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values. When one species has even the slightest ...

  7. Vacant niche - Wikipedia

    en.wikipedia.org/wiki/Vacant_niche

    Vacant niche. The issue of what exactly defines a vacant niche, also known as empty niche, and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they could theoretically become maximally saturated with species.

  8. Interspecific competition - Wikipedia

    en.wikipedia.org/wiki/Interspecific_competition

    The two species share the same ecological niche, and are thus in competition with each other. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis.

  9. Novel ecosystem - Wikipedia

    en.wikipedia.org/wiki/Novel_ecosystem

    Novel ecosystems are human-built, modified, or engineered niches of the Anthropocene.They exist in places that have been altered in structure and function by human agency. Novel ecosystems are part of the human environment and niche (including urban, suburban, and rural), they lack natural analogs, and they have extended an influence that has converted more than three-quarters of wild Earth ...
