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.
The Iberian lynx is suggested to have evolved from Lynx issiodorensis. [12] [13] Its earliest known fossil remains date to the end of the Early Pleistocene, around one million years ago. [1] The Iberian lynx genetically diverged as a unique species 1.98 to 0.7 million years ago.
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 ...
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 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]
[citation needed] The dog-specific hypothesis in particular cannot account for several major extinction events, notably the Americas (for reasons already covered) and Australia. Dogs did not arrive in Australia until approximately 35,000 years after the first humans arrived there, and approximately 30,000 years after the Australian megafaunal ...
The lynx population in Finland was 1900–2100 individuals in 2008, and the numbers have been increasing every year since 1992. The lynx population in Finland is estimated currently to be larger than ever before. [34] Lynx in Britain were wiped out in the 17th century, but there have been calls to reintroduce them to curb the numbers of deer. [35]
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.
