The extinction of the megafauna has been argued by some authors to be disappearance of the mammoth steppe rather than the other way around. Alaska now has low nutrient soil unable to support bison, mammoths, and horses. R. Dale Guthrie has claimed this as a cause of the extinction of the megafauna there; however, he may be interpreting it ...
Megafauna also play a role in regulating and stabilizing the abundance of smaller animals. During the Pleistocene, megafauna were diverse across the globe, with most continental ecosystems exhibiting similar or greater species richness in megafauna as compared to ecosystems in Africa today.
North Central Europe and the British Isles to Crimea and the Middle Urals: Most recent remains in north Central Europe are dated to 8750 BCE. [2] However, remains have been dated to the late Holocene in Ukraine, and one account describes a large, unidentified, "red-cheeked" ground squirrel in the early 20th century of the Dnipropetrovsk area.

In Europe, Homo heidelbergensis is known to have consumed the largest megafauna species present in the region, the straight-tusked elephant (which has been found at numerous sites with cut marks and/or stone tools indicating butchery) [43] and rhinoceroses belonging to the genus Stephanorhinus. [44]
Megafauna that arose on insular landmasses were especially vulnerable to human influence because they evolved in isolation from other landmasses, and thus were not subjected to the same selection pressures that surviving fauna were subject to, and many forms of insular megafauna were wiped out after the arrival of humans.
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
Elasmotherium arrived in Eastern Europe around 2.5 million years ago, during the earliest part of the Pleistocene epoch. [ 14 ] Hypsodonty , a dentition pattern where the molars have high crowns and the enamel extends below the gum line, is thought to be a characteristic of Elasmotheriinae, [ 15 ] perhaps as an adaptation to the heavier grains ...
Some 277 fish species have been introduced to Europe, and over one-third of Europe's current fish fauna is composed of introduced species, [19] whereas more than a third of Europe's freshwater fish species are at risk of extinction, according to new data released by the World Conservation Union (IUCN).
