The Last Glacial Maximum map with vegetation types. Last Glacial Maximum refugia were places in which humans and other species survived during the Last Glacial Period, around 25,000 to 18,000 years ago. [1] Glacial refugia are areas that climate changes were not as severe, and where species could recolonize after deglaciation. [2]
The advancing, or glacial periods can cause a massive displacement of flora and fauna as it drives them away from the poles, with the most recent glacial maximum having occurred about 20,000 years ago., [1] [2] Refugia may allow the persistence of populations and subsequent-recolonization. Some different types of these areas are coastal ...
European Last Glacial Maximum refugia, 20 kya. In biology, a refugium (plural: refugia) is a location which supports an isolated or relict population of a once more widespread species. This isolation can be due to climatic changes, geography, or human activities such as deforestation and overhunting.
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent between 26,000 and 20,000 years ago. [2]
A glacial refugium (plural glacial refugia) is a geographic region which made possible the survival of flora and fauna during ice ages and allowed for post-glacial re-colonization. [ 1 ] [ 2 ] Different types of glacial refugia can be distinguished, namely nunatak , peripheral, and lowland. [ 3 ]
The southern glacial maximums extended south to Washington state near Olympia in the west and to Spokane, the Idaho Panhandle, and much of Western Montana at the eastern glacial edge. At its eastern end the Cordilleran ice sheet merged with the Laurentide Ice Sheet at the Continental Divide , forming an area of ice that contained one and a half ...
The Last Glacial Maximum ("LGM") started c. 30 ka BCE, at the end of MIS 3, leading to a depopulation of Northern Europe. According to the classical model, people took refuge in climatic sanctuaries (or refugia) as follows: Northern Iberia and Southwest France, together making up the "Franco-Cantabrian" refugium; The Balkans
The sea-level data from the Rhine–Meuse Delta indicate a 2–4 m (6 ft 7 in – 13 ft 1 in) of near-instantaneous rise at 8.54 to 8.2 ka, in addition to 'normal' post-glacial sea-level rise. [26] Meltwater pulse sea-level rise was experienced fully at a great distance from the release area.
