Some green ash trees show some resistance to emerald ash borers

Genes in green ash trees that may confer some resistance to attacks by the emerald ash borer express themselves only once the tree detects the invasive beetle's feeding, according to Penn State researchers.

Climate warming could increase malaria risk in cooler regions

Malaria parasites develop faster in mosquitoes at lower temperatures than previously thought, according to researchers at Penn State and the University of Exeter. The findings suggest that even slight climate warming could increase malaria risk to hundreds of thousands, if not millions, of people — including travelers — in areas that are currently too cold for malaria parasites to complete their development.

South African forests show pathways to a sustainable future

Native forests make up one percent of the landscape in South Africa but could play a key role in reducing atmospheric carbon and identifying sustainable development practices that can be used globally to counter climate change, according to a Penn State researcher.

Ants maintain essential interactions despite environmental flux

Ants adjust their social interactions to accommodate changes in population density, according to researchers at Penn State and Georgetown University. The findings suggest that ant colonies are capable of maintaining their sophisticated social organization despite potentially drastic changes in their environments.

Northeastern deer more susceptible to wasting disease than those to the west

Some deer are more susceptible to chronic wasting disease that is spreading through herds of white-tailed deer across much of the United States, according to Penn State researchers.

NIFA awards grant for microbial stress tolerance research

The National Institute of Food and Agriculture (NIFA) recently awarded Kevin Hockett $453,000 to assist in research focusing on how microbes tolerate distinct stresses.

New records show spread of parasitic deer flies across the US

With flattened bodies, grabbing forelegs and deciduous wings, deer keds do not look like your typical fly. These parasites of deer — which occasionally bite humans — are more widely distributed across the U.S. than previously thought.

Ecology Institute announces call for new research center proposals

The Ecology Institute has established a modest funding program to help support the development of new centers that have a central ecological theme. The aim is to add value to ongoing basic and applied ecological research and to foster new collaborations across the Penn State community.
