  2. Paradox of enrichment - Wikipedia

    en.wikipedia.org/wiki/Paradox_of_enrichment

    A common example is that if the food supply of a prey such as a rabbit is overabundant, its population will grow unbounded and cause the predator population (such as a lynx) to grow unsustainably large. That may result in a crash in the population of the predators and possibly lead to local eradication or even species extinction.

    en.wikipedia.org/wiki/Wikipedia:Conservation_status

    Examples: Slender-billed Curlew, Spanish Lynx, Red Wolf. Extinct in the Wild ( EW ): captive individuals survive, and/or the species has been reintroduced outside its former natural range, but the species otherwise matches the criteria for "Extinct", such that no free-living, natural population is believed to exist.

  4. Latent extinction risk - Wikipedia

    en.wikipedia.org/wiki/Latent_extinction_risk

    In conservation biology, latent extinction risk is a measure of the potential for a species to become threatened.. Latent risk can most easily be described as the difference, or discrepancy, between the current observed extinction risk of a species (typically as quantified by the IUCN Red List) and the theoretical extinction risk of a species predicted by its biological or life history ...

  5. Species–area relationship - Wikipedia

    en.wikipedia.org/wiki/Species–area_relationship

    Species–area relationships are often evaluated in conservation science in order to predict extinction rates in the case of habitat loss and habitat fragmentation. [8] Authors have classified the species–area relationship according to the type of habitats being sampled and the census design used.

  6. Local extinction - Wikipedia

    en.wikipedia.org/wiki/Local_extinction

    Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. [1] [2] Local extinctions mark a change in the ecology of an area.

  7. Extinction threshold - Wikipedia

    en.wikipedia.org/wiki/Extinction_threshold

    For example, in an article published in 2004, Otso Ovaskainen and Ilkka Hanski explained with an empirical example that when factors such as Allee effect or Rescue effect were included in modeling the extinction threshold, there were unexpected extinctions in a high number of species. A more complex model came up with different results, and in ...

  8. Extinction risk from climate change - Wikipedia

    en.wikipedia.org/wiki/Extinction_risk_from...

    The effects that climate change has on both plant and animal species within certain ecosystems has the ability to directly affect the human inhabitants who rely on natural resources. Frequently, the extinction of plant and animal species create a cyclic relationship of species endangerment in ecosystems which are directly affected by climate ...

  9. Cascade effect (ecology) - Wikipedia

    en.wikipedia.org/wiki/Cascade_effect_(ecology)

    An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem.
