The Lilliput effect is an observed decrease in animal body size in genera that have survived a major extinction. [1] There are several hypotheses as to why these patterns appear in the fossil record, some of which are: [2] simple preferential survival of smaller animals, dwarfing of larger lineages, and
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.
In an example of conservation-induced extinction, it likely died out when the last survivors of its host species, the Iberian lynx, were taken into captivity and de-loused. [3] The specimen is slightly larger than males of most of the remaining species within the subgenus Lorisicola . [ 1 ]
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 .
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 ...
End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling and other effects Olson's Extinction: 270 Ma Unknown. [29] [30] [31] Possibly a change in climate, but evidence for this is weak. [32] This event may actually be a slow decline over 20 Ma. [33] Carboniferous: Carboniferous rainforest ...
By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating, reintroducing and monitoring Iberian lynxes ...
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 ...
