متن کاملHolocene Dynamics of Temperate Rainforests in West-Central Patagonia
Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition. In this study, we (1) used lithology, pollen, and charcoal data from Mallín Casanova (47S) to reconstruct the wetland, vegetation, and fire history of west-central Patagonia; and (2) compared th...
متن کاملThe influence of temperature, moisture, and eolian activity on Holocene lake development in West Greenland
Holocene paleolimnological records (diatoms, organic content, spectrally inferred sediment chlorophyll-a) from three West Greenland lakes (~67°N) situated along a transect from the outer coast to a nunatak at the periphery of the Greenland Ice Sheet are used to explore the nature of regional postglacial lake development and its relationship to Holocene climate evolution. The lakes were deglacia...
متن کاملAbrupt Holocene climate change as an important factor for human migration in West Greenland.
West Greenland has had multiple episodes of human colonization and cultural transitions over the past 4,500 y. However, the explanations for these large-scale human migrations are varied, including climatic factors, resistance to adaptation, economic marginalization, mercantile exploration, and hostile neighborhood interactions. Evaluating the potential role of climate change is complicated by ...
متن کاملEarly Holocene history of the west Greenland Ice Sheet and the GH-8.2 event
The margin of the Greenland Ice Sheet retreated rapidly during the first few thousand years of the Holocene. During this period of relative warmth, known as the Holocene thermal maximum, ice core records identify a significant short-lived cooling event at approximately 8.4–8.0 ka cal. yr BP (the ‘GH-8.2 event’) associated with a 5–7 1C fall in mean annual air temperature over the centre of the ...
