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 ...
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 .
The Eurasian lynx (Lynx lynx) is one of the four extant species within the medium-sized wild cat genus Lynx. It is widely distributed from Northern, Central and Eastern Europe to Central Asia and Siberia, the Tibetan Plateau and the Himalayas. It inhabits temperate and boreal forests up to an elevation of 5,500 m (18,000 ft).
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 ...
The Balkan lynx has been on the brink of extinction for nearly a century, with total numbers estimated to be fewer than 50. [5] The Balkan lynxes' decrease in number have been thought to be due to illegal poaching. [15] The Balkan lynx starts mating around January to February, and gives birth in April. [16]
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.
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 ...
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 ...
