16 lut 2021 · The disappearance of many North American megafauna at the end of the Pleistocene is a contentious topic. While the proposed causes for megafaunal extinction are varied, most researchers...
24 lis 2023 · The worldwide extinction of megafauna during the Late Pleistocene and Early Holocene is evident from the fossil record, with dominant theories suggesting a climate, human or combined impact...
14 lut 2023 · Thus, it is probable that the widespread extinction of herbivorous megafauna in the late Pleistocene influenced atmospheric gas exchange and global climate. Several authors have calculated the enteric production of methane by megafauna at the terminal Pleistocene.
As the Pleistocene came to an end in North America, 38 genera of mammals vanished . The majority are designated as megafauna, with a body mass over ∼45 kg, including several proboscideans (mammoth, mastodon, gomphothere) weighing more than 4,500 kg.
22 mar 2024 · Across the last ~50,000 years (the late Quaternary) terrestrial vertebrate faunas have experienced severe losses of large species (megafauna), with most extinctions occurring in the Late Pleistocene and Early to Middle Holocene. Debate on the causes has been ongoing for over 200 years, intensifying from the 1960s onward.
25 sty 2016 · As in Late Pleistocene North America, contemporary direct human pressures on megafaunal populations are coinciding with an episode of potentially rapid climate change. Restored megafaunas and associated trophic cascades may provide increased ecological resilience against climate change in some cases ( 33 ).
