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.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Tennessee, Cumberland, Ohio, and Wabash River systems [ 192 ] Extinct in 1936 due to loss of habitat through impoundment or channelization. [ 8 ] Sampson's pearly mussel. Epioblasma sampsonii. Kentucky, Illinois, and Indiana [ 193 ] Extinct in the 1930s or 1940s due to habitat destruction and fragmentation.

The Holocene (/ ˈ h ɒ l. ə s iː n,-oʊ-, ˈ h oʊ. l ə-,-l oʊ-/) [2] [3] is the current geological epoch, beginning approximately 11,700 years ago. [4] It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. [4] The Holocene and the preceding Pleistocene [5] together form the Quaternary period.
Map of Europe. This is a list of European species 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. This list includes the European continent and its surrounding islands.
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna (typically defined as animal species having body masses over 44 kilograms (97 lb)), [ 1 ] which resulted in a collapse in faunal density and diversity across the globe. [ 2 ]
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, Holocene Optimum, Holocene ...
