Researchers found that the increased radiation dose from the muons as a result of the erupting stars contributed to the marine megafaunal
A supernova 2.6 million years ago may be related to a marine megafaunal
extinction at the Pliocene-Pleistocene boundary where 36 percent of the genera were estimated to become extinct.
The study also confirmed previous evidence of megafaunal
extinction starting around 1200 years BP.
The large size of many of these fruits has led authors to conclude the megafaunal
mammals were the main seed dispersers for these species (janzen and Martin.
Fifty thousand years of Arctic vegetation and megafaunal
There have been plenty of other oversized penguins in the fossil record, but those species came tens of millions of years later, leading many researchers to figure that it probably took time for penguins to evolve into megafaunal
Thieving rodents as substitute dispersers of megafaunal
Abyssal hills - hidden source of increased habitat heterogeneity, benthic megafaunal
biomass and diversity in the deep sea.
First, Bison survived the megafaunal
extinction at the end of the Pleistocene approximately 11,700 calendar years Before Present (cal yr BP) and, in North America, the genus outlived mammoths (Mammuthus), mastodons (Mammut), horses (Equus), ground sloths (Megalonyx et al.), and other megafauna while coexisting with early Americans (Paleoindians; Koch and Barnosky, 2006).
Establishing a baseline of understanding and quantifying the role of megafaunal
cleaning stations is a useful component in the assessment of ecosystem health in this protected region.
To correct this dramatic megafaunal
loss, Josh Donlan and ten other biologists, including Foreman and Soule, have launched the idea of 'Pleistocene rewilding' (Donlan et al., 2005, 2006).
