  4. Behavioral ecology - Wikipedia

    en.wikipedia.org/wiki/Behavioral_ecology

    Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?

  5. Ecosystem ecology - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_ecology

    Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .

  6. Species–area relationship - Wikipedia

    en.wikipedia.org/wiki/Species–area_relationship

    Larger areas tend to contain larger numbers of species, and empirically, the relative numbers seem to follow systematic mathematical relationships. [1] The species–area relationship is usually constructed for a single type of organism, such as all vascular plants or all species of a specific trophic level within a particular site. It is ...

    en.wikipedia.org/wiki/Quantitative_ecology

    Quantitative ecology is the application of advanced mathematical and statistical tools to any number of problems in the field of ecology.It is a small but growing subfield in ecology, reflecting the demand among practicing ecologists to interpret ever larger and more complex data sets using quantitative reasoning.

  8. Competitive exclusion principle - Wikipedia

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

    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 advantage over another, the one with the advantage will dominate in the long term.

  9. Lotka–Volterra equations - Wikipedia

    en.wikipedia.org/wiki/Lotka–Volterra_equations

    Suppose there are two species of animals, a rabbit (prey) and a fox (predator). If the initial densities are 10 rabbits and 10 foxes per square kilometre, one can plot the progression of the two species over time; given the parameters that the growth and death rates of rabbits are 1.1 and 0.4 while that of foxes are 0.1 and 0.4 respectively.
