National Science Foundation forum to address ecological connectivity and climate in a changing world

On Thursday, Feb. 26, 2009, the National Science Foundation (NSF) will host its 8th annual Mini-Symposium on Long-Term Ecological Research, or LTER. This year's forum focuses on ecological connectivity and climate. We live in an increasingly connected world. In an ecological context, connect...

Inmates conduct ecological research on slow-growing mosses

Nalini Nadkarni of Evergreen State College currently advises a team of researchers who sport shaved heads, tattooed biceps and prison-issued garb rather than the lab coats and khakis typically worn by researchers. Why is Nadkarni's team composed of such apparently iconoclastic researchers? Because...

Logging changed ecological balance for monkeys, damaged health

Twenty-eight years after intense selective logging stopped in the region now known as Uganda's Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. The logging practice, scientists report in a new study, changed the ecological balance for these monkey...

UN: World in big ecological mess
