2018年6月7日 · The Bering Land Bridge was episodically open throughout the Pleistocene until about 13,000 years ago. A corridor was created by falling sea levels that provided an opportunity for Asian species including mammoths, bison, muskoxen, caribou, lions, brown bears, and wolves to move into North America.

2019年2月7日 · This unglaciated region, which extended from the Yukon Territory in Canada west across to eastern Siberia, is called Beringia. Because so much of the planet’s water was locked up in glaciers, sea level was much lower than it is now, and Alaska and Siberia were connected by the Bering Land Bridge (Figure 1).

2015年11月2日 · The Bering Land Bridge was finally submerged between 12 and 13 calendar ka B.P. (60, 61) when sea level surpassed the −50-m level, a height not reached for the previous 40,000 y. By the early Holocene, relative sea level stood higher along the coast of northern Alaska than it had at any time in the previous 100,000 y ( 62 , 63 ).

Archeological evidence suggests that Homo sapiens did not cross the Bering straight land bridge from Siberia to North America until approximately 12,000-14,000 years ago, long after the impact event.

2004年11月26日 · Periodic exposure of the Bering Land Bridge facilitated the exchange of a diverse megafauna (such as bison, mammoth, and musk ox) supported by tundra-steppe grasses and shrubs (3, 4). Humans are believed to have colonized North America via this route, and the first well-accepted evidence of human settlement in Alaska dates to around 12 ky B.P ...

Aim The Bering Land Bridge (BLB) connected Asia and North America during glacial periods, supported a diverse ecosystem of now-vanished megafauna, and is a proposed glacial refugium. This study tests whether southern coastal Berin-gia was a refugium for woody taxa during the Last Glacial Maximum (LGM)

The land bridge becomes very broad and connects the entire north of Lutruwita/Tasmania to a large swathe of southern Victoria extending from Cape Otway to east Gippsland. A vast freshwater lake (Lake Bass) lies in the centre of the Bassian Plain, fed by the Kanamaluka/Tamar River and possibly the Toulerm/Tarwin River.

2022年1月26日 · During the last glacial period, the Bering Land Bridge was inhabited by a diverse bestiary of large mammals, many now extinct , and covered by the steppe-tundra, a widespread, now largely vanished biome . Given the twinned losses of big animals and a major ecosystem during the last deglaciation, a central question is to understand whether and ...

This land is called a land bridge, as it enabled people and wildlife to cross from one side to the other. But the land was more than just a bridge. Scientists like to call it the ‘Bassian Plain’ because the exposed lowlands were vast.

Mainland Australia became connected to the great southern island of Lutruwita/Tasmania. This connection is called a ‘land bridge’ because people, plants, and animals could use it to cross to distant lands which before had been separated by the sea. Scientists have named this ancient landscape the Bassian Plain.
