  2. Carrying capacity - Wikipedia

    en.wikipedia.org/wiki/Carrying_capacity

    The carrying capacity is defined as the environment's maximal load, [clarification needed] which in population ecology corresponds to the population equilibrium, when the number of deaths in a population equals the number of births (as well as immigration and emigration). Carrying capacity of the environment implies that the resources ...

  3. Overshoot (population) - Wikipedia

    en.wikipedia.org/wiki/Overshoot_(population)

    Carrying capacity – Maximum population size of a species that an environment can support; Earth Overshoot Day – Calculated calendar date when humanity's yearly consumption exceeds Earth's replenishment; Ecological footprint – Individual's or a group's human demand on nature; Ecological overshoot – Demands on ecosystem exceeding regeneration

  4. Biocapacity - Wikipedia

    en.wikipedia.org/wiki/Biocapacity

    Global biocapacity' is a term sometimes used to describe the total capacity of an ecosystem to support various continuous activity and changes. When the ecological footprint of a population exceeds the biocapacity of the environment it lives in, this is called an 'biocapacity deficit'. Such a deficit comes from three sources: overusing one's ...

  5. Ecological overshoot - Wikipedia

    en.wikipedia.org/wiki/Ecological_overshoot

    Ecological overshoot expressed in terms of how many Earths equivalent of natural resources are consumed by humanity each year. Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity.

  6. Population ecology - Wikipedia

    en.wikipedia.org/wiki/Population_ecology

    In a population, carrying capacity is known as the maximum population size of the species that the environment can sustain, which is determined by resources available. In many classic population models, r is represented as the intrinsic growth rate, where K is the carrying capacity, and N0 is the initial population size. [5]

  7. Population model - Wikipedia

    en.wikipedia.org/wiki/Population_model

    The logistic model takes the shape of a sigmoid curve and describes the growth of a population as exponential, followed by a decrease in growth, and bound by a carrying capacity due to environmental pressures. [4]

  8. I = PAT - Wikipedia

    en.wikipedia.org/wiki/I_=_PAT

    If "I" exceeds the carrying capacity, then the system is said to be in overshoot, which may only be a temporary state. Overshoot may degrade the ability of the environment to endure impact, therefore reducing the carrying capacity. Impact may be measured using ecological footprint analysis in units of global hectares (gha). Ecological footprint ...

  9. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    These terms, r, and K, are derived from standard ecological algebra, as illustrated in the simple Verhulst equation of population dynamics: [30] = where r is the growth rate of the population (N), and K is the carrying capacity of its
