Penn State unit partner projects highlight awareness, importance of pollinators

Penn State's Center for Pollinator Research and the Insect Biodiversity Center, both at the Huck Institutes of the Life Sciences, and the Department of Graphic Design at the Penn State College of Arts and Architecture have formed a partnership, funded by the Apes Valentes Program, to develop, design and produce materials to help increase awareness of pollinator biodiversity, the importance of pollinators to food security and ecosystem health, and strategies that can be used to support pollinators in urban, agricultural and natural landscapes.

Managing habitat for flowering plants may mitigate climate effects on bee health

Warm, wet weather conditions and changing climate negatively influence the nectar intake and nutritional health of honey bees, but maintaining large tracts of grassy natural habitat with flowering plants around apiaries may help to mitigate the detrimental effects of climate, according to a new study by an international team of researchers.

Huck Students Receive Alumni Awards

Two Huck IGDP students have been recognized as part of the 2021-22 Graduate School Alumni Association faculty and student awards in the Life & Health Sciences section.

Mining for knowledge: Scientists identify bee that can aid black cherry recovery

A ground-nesting bee family — commonly known as miner bees — could play a heightened role in rebuilding black cherry populations in Pennsylvania and beyond, according to Penn State entomologists who investigated pollinators’ contributions to the valuable hardwood species.

The Secret Chemistry that Makes Honey a Scientific Wonder

It should come as no surprise that bees know a lot about honey. They aren’t only honey producers — they are also consumers and pretty sophisticated ones at that. Offer a sick bee different varieties of honey, for example, and it will choose the one that best fights off its infection.

Popular perennial flowering plants can attract diverse mix of pollinators

Popular species of perennial flowering plants vary widely in their attractiveness to pollinators, but homeowners and landscape managers who select certain perennial cultivars can support a diverse community of pollinators in their own backyards, according to a new study from a team of Penn State researchers.

Penn State centers collaborate on pollinator education project

A recently awarded USDA grant will allow CPR researchers and Center for Science and the Schools partners to partner with elementary school teachers in Pennsylvania to develop cross-disciplinary curricula that support students in understanding pollinator research in the areas of food, agriculture and natural resources.

USDA grant to support expansion of online tool for bee conservation

A Penn State-led research team has received a nearly $950,000 U.S. Department of Agriculture grant to create the next generation of an online decision-support tool designed to help conserve pollinator populations across the United States.

Undergraduate Research Award Funds Pollinator Photo Project

Darya Alvarez completed a photography project funded by an Apes Valentes Undergraduate Research Award. Her goal is to help viewers gain a greater appreciation of the critical role that bees play in the survival of terrestrial ecosystems.
