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.

Book on weeds and invasive plants discusses how to manage them using ecological approaches
RIVERSIDE, Calif. As people become more globally mobile, plants can inadvertently get transported with them, resulting in new plants appearing in places not used to hosting them. Such invasions of exotic species can occur rapidly, taking over new territories at the expense of native plants.
Human's ecological footprint in 2015 and Amazonia revealed

The ecological effects of the Chernobyl disaster
Nearly 20 years ago Reactor number 4 at Chernobyl exploded, sending radiation across a large region of what is now the Ukraine, Belarus, and Russia.

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...
