Migration patterns reveal an Eden for ancient humans and animals

Home to some of the richest evidence for the behavior and culture of the earliest clearly modern humans, the submerged shelf called the Palaeo-Agulhas Plain (PAP) once formed its own ecosystem. Co-author Curtis Marean, Ph.D., ...

The shelf life of pyrite

The last 2.6 million years are characterized by glacial cycles, a regular alternation of cold and warm periods. It is widely accepted that changes in the concentrations of carbon dioxide and other greenhouse gases in the ...

Afromontane forests and climate change

In the world of paleoecology, little has been known about the historical record of ecosystems in the West African highlands, especially with regard to glacial cycles amidst a shifting climate and their effects on species ...

A dusty atmosphere caused extreme global cooling

In recent Earth history, climate has varied following ~100,000 year, glacial-interglacial cycles with higher and lower temperatures and greenhouse gas concentrations. During the coldest glacial conditions, global mean temperatures ...

Ice age vertebrates had mixed responses to climate change

New research examines how vertebrate species in the eastern United States ranging from snakes to mammals to birds responded to climate change over the last 500,000 years. The study, recently published in the journal Ecology ...

A song of fire and ice in the ocean

Cyclic changes in the tilt of the Earth's axis and the eccentricity of its orbit have left their mark on hills deep under the ocean, a study published in Science has found.

Climate change makes more shrew species, 70 genetic varieties

Anyone who went outside this summer felt the effects of climate change. Now the Eurasian shrew, Sorex araneus, can say the same. A new study by P. David Polly of Indiana University found that climate change caused shrews ...
