The Holocene extinction, or Anthropocene extinction, [3] [4] is the ongoing extinction event caused by humans during the Holocene epoch. These extinctions span numerous families of plants [ 5 ] [ 6 ] [ 7 ] and animals, including mammals , birds, reptiles, amphibians , fish, and invertebrates , and affecting not just terrestrial species but also ...
1926 [ 415 ] Extermination campaign. The Great Plains wolf has been later determined to be continuous morphologically [ 410 ] and genetically [ 416 ] with the still existing Mexican wolf, which would use the name C. l. nubilus if placed in the same subspecies, due to being the older one. Red-moustached fruit dove.
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, [104] [105] is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
The 4.2-kiloyear (thousand years) BP aridification event (long-term drought), also known as the 4.2 ka event, [2] was one of the most severe climatic events of the Holocene epoch. [3] It defines the beginning of the current Meghalayan age in the Holocene epoch. Starting around 2200 BC, it most likely lasted the entire 22nd century BC.
This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
The largest extinction was the Kellwasser Event (Frasnian - Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods, and trilobites.
There is no general agreement on where the Quaternary extinction event ends, and the Holocene, or anthropogenic, extinction begins, or if they should be considered separate events at all. [244] [245] Some authors have argued that the activities of earlier archaic humans have also resulted in extinctions, though the evidence for this is ...
Holocene climatic optimum. The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, that occurred in the interval roughly 9,500 to 5,500 years BP, [ 1 ] with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal ...
