Ottar Bjørnstad elected to Norwegian Academy of Sciences and Letters

Ottar N. Bjørnstad, distinguished professor of entomology and biology and J. Lloyd & Dorothy Foehr Huck Chair of Epidemiology at Penn State, has been elected to the Norwegian Academy of Sciences and Letters. Bjørnstad was recommended as a result of his significant contributions to the fields of population ecology and quantitative epidemiology.

Wolf social group dynamics matter for infectious disease spread, models suggest

By modeling wolves in Yellowstone National Park, researchers have discovered that how a population is organized into social groups affects the spread of infectious diseases within the population. The findings may be applicable to any social species and could be useful in the protection of endangered species that suffer from disease outbreaks.

Unique study of isolated bobcat population confirms accuracy of extinction model

The reintroduction of 32 bobcats to an island off the coast of Georgia more than three decades ago created an ideal experiment to examine the accuracy of a genetic-modeling technique that predicts extinction of isolated wildlife populations.

Silencing the alarm

An enzyme in the saliva of certain insects prevents their food plants from warning neighboring plants of an attack.

The business of bees

The economic value of insect pollination services is much higher than previously thought in the U.S., new research finds.

Summer weather conditions influence winter survival of honey bees

Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to Penn State researchers, who said their findings suggest that honey bees have a "goldilocks" preferred range of summer conditions outside of which their probability of surviving the winter falls.

Ecology Institute to hold pitch slam for funding competition

The Ecology Institute announced a funding competition for its annual Flower Grant for Ecological Research. The events, which will take place as virtual pitch slams, will occur from noon to 1 p.m. on March 9 and 10. The Ecology Institute is inviting researchers who are seeking funding to participate.

Grozinger receives National Academy's Prize in Food and Agriculture Sciences

Christina Grozinger, Publius Vergilius Maro Professor of Entomology in Penn State's College of Agricultural Sciences, will be honored by the National Academy of Sciences for helping the world understand how to address the crisis of global declines in pollinator populations.

Arts and Architecture appoints interim head of landscape architecture

Charles Andrew “Andy” Cole, associate professor of landscape architecture and ecology and the director of the E+D: Ecology plus Design research initiative, has been appointed the interim head of the Department of Landscape Architecture by Penn State College of Arts and Architecture Dean B. Stephen Carpenter II.

Climate change reduces the abundance and diversity of wild bees, study finds

Wild bees are more affected by climate change than by disturbances to their habitats, according to a team of researchers led by Penn State. The findings suggest that addressing land-use issues alone will not be sufficient to protecting these important pollinators.
