Geneticists close to grasping how plant communities may adapt to climate change

A century after scientists first noted that the environment contributes to the evolution of adaptive differences among plant populations, scientists are on the verge of figuring out how that adaptation happens — by combining results from huge “common garden” experiments with genomic sequencing.

Nita Bharti to deliver 2022 Darwin Day Lecture

Nita Bharti, Penn State assistant professor of biology, will deliver a virtual lecture titled “Adaptation for Survival: Humans and Their Pathogens” at 4 p.m. on Thursday, Feb. 10, as part of Penn State’s 2022 Darwin Day celebration. Advance registration is required for the event, which is open to the public.

Penn State biologists explore the secrets of the warbler genome

Looking through binoculars at the trees in their backyards during the pandemic, many brand-new birders may have been surprised by the diversity of visitors stopping by — finches, jays and warblers in an astounding array of yellows, blues and reds.

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.

Entomologists to study how climate change may influence pollinator stressors

A Penn State-led team of researchers will use a newly awarded $682,000 grant from the U.S. Department of Agriculture's National Institute of Food and Agriculture to examine how climate change may influence and interact with various stressors that affect the health of pollinators.

Researchers use satellites to monitor bat habitat and study virus spillover

Over the last year and a half, the word "remote" has come to dominate a large portion of our collective consciousness. We’ve had to work remotely, learn remotely, and even socialize remotely. But before the pandemic, because of the nature of their research, remote was already a part of the daily lexicon of some Penn State researchers.

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.

Scientists uncover the genetic pathway that colors bumble bee stripes

While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry.

Warm, wet autumn could mute and delay foliage display in Pennsylvania

Because of the warm, wet summer, trees in Pennsylvania are mostly in great shape. But for the state’s forests to exhibit their most vibrant colors, conditions need to be cooler and drier in the next few weeks, according to a Penn State expert.

Long-distance relationships for endangered corals

Flash-frozen sperm collected from corals in Florida and Puerto Rico was used to fertilize coral eggs from hundreds of miles away in Curaçao. The technique could be used as a conservation tool by introducing genetic variation into endangered corals and potentially accelerating their adaptation to climate change.
