Snapshot USA: First-ever nationwide mammal survey now published

The results of the first national mammal survey, now publicly available online, provide the framework to answer a variety of questions about wild animal populations and conservation strategies for threatened species. The survey, which involved researchers from across the country including a biologist at Penn State, is made up of data from 1,509 motion-activated camera traps from 110 sites located across all 50 states.

PlantVillage team lauded for projects to protect food supply amid COVID, locusts

Penn State researchers responsible for PlantVillage, a mobile app that helps farmers diagnose crop diseases and monitor pests, have been lauded for their work to help African farmers overcome challenges related to desert locusts and COVID-19.

Penn State biologist and colleagues receive $4M to identify heat-tolerant corals

An international team that includes Penn State biologist Iliana Baums has been awarded a $4 million grant from the Paul G. Allen Family Foundation to identify corals that are naturally resilient to climate change. This is one of four newly funded projects supported by the foundation that are focused on the conservation and restoration of coral reefs in the context of the climate crisis.

Reef-building corals and microscopic algae within their cells evolve together

The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another’s needs. A new study by Penn State biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals.

Widespread coral-algae symbioses endured historical climate changes

One of the most important and widespread reef-building corals, known as cauliflower coral, exhibits strong partnerships with certain species of symbiotic algae, and these relationships have persisted through periods of intense climate fluctuations over the last 1.5 million years, according to a new study led by researchers at Penn State.

Maternal stress during pregnancy may shorten lifespans of male lizard offspring

Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study.

Little crop of horrors

An international team of researchers has received a grant from the Human Frontier Science Program to investigate how carnivory-related genes, such as those involved in digestion, could help crops not only avoid pests, but also thrive in low-nutrient environments.

New position will support graduate and post-graduate training

Donna Korzick, professor of physiology and kinesiology, recently assumed a new role as director of graduate training initiatives in the Huck Institutes for the Life Sciences. In this role, Korzick is dedicating half of her time to support the application for and execution of training grants from organizations like the National Institutes of Health.

Three Huck Students Collect Grad School Awards

Two students from the intercollegiate graduate degree program in plant biology and one from ecology have been named among the recipients of prestigious 2020-21 Penn State Graduate School awards.

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.
