Craig Loehle and Willis Eschenbach are the authors of “Historical bird
and terrestrial mammal extinction rates and causes” (Diversity and Distributions 18(1):84-91). Loehle and Eschenbach
review several lines of evidence indicating that high extinction rates on
islands are attributable to effects of uncontrolled hunting by humans and
predation by introduced animal species. They also discuss reasons why models of
extinction risk based on rates and causes of extinction on islands have limited
applicability in conservation strategies for birds and mammals on continents.

species are among the most widely planted tree species in the world and of
increasing interest as a bioenergy feedstock in the Coastal Plain of the US
South. To help address environmental issues related to its potential culture in
this region, NCASI and the USDA Forest Service Southern Research Station have
assembled experts from the US and abroad to share data and perspectives in the Symposium on the Assessment and Management
of Environmental Issues Related to Eucalyptus Culture in the Southern United
In October 2011, the US
Environmental Protection Agency (EPA) released its final National Pollutant
Discharge Elimination System (NPDES) Pesticide General Permit (PGP) for point
source discharges from the application of pesticides to waters of the United
States. EPA developed the PGP to provide an option for some pesticide
applicators/managers to comply with NPDES permit requirements without having to
obtain coverage under individual permits, which generally take longer to obtain
and are more burdensome than general permits.
In October 2011, the US Fish
