A study documented the comprehensive responses of microbial community characteristics to degradation processes using field-based sampling, and soil microcosm experiments were conducted to simulate effects of global change on microorganisms and explore their relationships to ecosystem functioning across stages of alpine pioneer community degradation.

A study in Ecology Letters shows birds worldwide make strategic decisions about how they live based on their environmental conditions. Some live fast, die young, and leave as many chicks as possible. Others live long and prosper by not breeding.

A new study by an international team of researchers, including Jackie Dawson, full professor, Geography, Environment and Geomatics at the University of Ottawa’s Faculty of Arts, underscores the grave risks posed by insufficient national commitments to reducing greenhouse gas emissions.

It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently, with ever-larger icebergs in the waters around Antarctica. Researchers from Utrecht University are studying the routes that icebergs followed during geological periods of rapid ice cap deterioration, such as the ends of ice ages. That provides crucial information about the effect of melting icebergs on the oceans, and its consequences for the future. In the process, they also found an explanation for the mysterious discovery of ancient material from Antarctica near South Orkney, an island to the southwest of South Georgia.
