Invasive grass may impede forest regeneration
04-09-2007 · EurekAlert!
The non-native invasive grass Microstegium vimineum may hinder the regeneration of woody species in southern forests. Chris and Sonja Oswalt (Forest Service Southern Research Station) and Wayne Clatterbuck (University of Tennessee) set up experiments on a mixed-hardwood forest in southwest Tennessee to study the growth of the invasive grass under different levels of forest disturbance. Study results were published online in the journal Forest Ecology and Management on March 27, 2007.

Predicting the perfect predator
02-13-2008 · EurekAlert!
Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has created a computer model that in combination with quarantined research tests he believes will be able to predict the perfect predator -- a pest that can be introduced into a forested area that will help reduce the garlic mustard population.

As a river runs through it, a Death Valley stream offers insights into flooding and climate change
01-30-2008 · EurekAlert!
Death Valley's Furnace Creek Wash, diverted in 1941 to protect a village from flooding, has carved through the sandy hills and bedrock of Gower Gulch to reveal the forces original landscape and changing channel dynamics exert on the responses of diverted rivers and streams, according to research published in the February edition of the journal Geology.
