He described an effect in six predator–prey models where increasing the food available to the prey caused the predator's population to destabilize. 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 ...
Each subdivision within this theory generates similar explanations for the coexistence of species with habitat disturbance. Joseph H. Connell [6] proposed that relatively low disturbance leads to decreased diversity and high disturbance causes an increase in species movement. These proposed relationships lead to the hypothesis that intermediate ...
Lynx Trust UK are a registered charity campaigning for the reintroduction of lynx to the Kielder Forest in Northumberland. [4] In 2018, a proposal to release six animals was turned down by then-Environment Secretary Michael Gove, [5] due to findings that the proposal did not "meet the necessary standards set out in the IUCN (International Union for Conservation of Nature) guidelines and fails ...
In a contrasting tale, conservation efforts have revived the Iberian lynx from the brink of extinction, with the population increasing from 62 mature individuals in 2001 to 648 in 2022 and more ...
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.
The Theory of Island Biogeography has its roots in Wilson's work on the ants of Melanesia.MacArthur synthesized Wilson's ideas about competition, colonization and equilibrium into a simple graphical representation of immigration and extinction curves, from which one can determine the equilibrial species number on an island.

The mediaeval great chain of being as a staircase, implying the possibility of progress: [1] Ramon Lull's Ladder of Ascent and Descent of the Mind, 1305. Alternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things.
A simple way to extend the Levins' model to incorporate space and stochastic considerations is by using the contact process. Simple modifications to this model can also incorporate for patch dynamics. At a given percolation threshold, habitat fragmentation effects take place in these configurations predicting more drastic extinction thresholds. [8]
