Whether a wild cottonmouth snake will attempt to strike in an encounter depends on its baseline stress level, according to a team of scientists led by undergraduate researcher Mark Herr, who completed the Wildlife and Fisheries Science baccalaureate degree in 2016.
Shifts in plant-growth patterns have been widely reported in response to global warming, and it is well documented that warming generally advances aboveground plant growth, noted Laura Radville, a doctoral candidate in ecology advised by David Eissenstat, professor of woody plant physiology. But warming's influence on root phenology is unclear.
Shannon White, a doctoral degree student in Penn State's ecology program, is investigating whether certain traits and behaviors may help brook trout populations adapt to habitat pressures including warming climate conditions.
The intense wildfires that swept through the Smokey Mountains in Tennessee late last month were a tragic melding of the past and the future, according to Marc Abrams, professor of forest ecology and physiology.
The Office of Multicultural Affairs in the College of Agricultural Sciences hosted a panel to highlight the career paths and accomplishments of several notable alumni (including Herbert White, 2000 FORSC) on Nov. 9.
A little-known ash plantation on the edge of Penn State's University Park campus — the largest collection of green ash germplasm in one location in the world — likely will play a significant role in saving the species, which is being decimated by an insect from Asia. Kim Steiner, professor of forest biology, and molecular geneticist John Carlson are looking at the genetic mechanisms by which surviving trees might be battling the insects.
Megan Reed completed the B.S. in Wildlife and Fisheries Science in May 2011 and is currently employed by the U.S. Fish and Wildlife Service in Washington, DC, as Special Assistant to both the Chief of the National Wildlife Refuge System and the Assistant Director for External Affairs.
The 27-year-old traditional breeding program, which has attempted to infuse blight resistance from the Chinese chestnut tree into American chestnuts, is receiving a boost from tree molecular geneticists at Penn State and five other universities working collaboratively in a bid to improve the process. While traditional breeding has been taking place, so have parallel lines of research into genetic modification and also bio-control of the fungus that causes the blight.
Between now and the third week in November, the Forestland Management Office in the Penn State Department of Ecosystem Science and Management will permit the Pennsylvania Game Commission (PGC) to complete one prescribed fire within the boundary of the Penn State Stone Valley Forest in northern Huntingdon County.
It took 32 years to build both the Great Pyramid of Giza and the Washington Monument. And it took 32 years for Penn State Distinguished Professor of Ichthyology Jay Stauffer to publish his landmark book, "The Fishes of Pennsylvania."
The yellow-legged frog's comeback out West seems to show that amphibians have the capacity to develop resistance to disease and tolerance for contaminants and suggests that they can survive in the East and around the world. At least that's the hope of David Miller, assistant professor of wildlife population ecology in Penn State's College of Agricultural Sciences, who is a member of the research team.
Wildlife and Fisheries Science alumnus applies ecology and public outreach to control the spread of aquatic invasive species
High-school-aged members of the Wildlife Leadership Academy, based in Lewisburg, PA, learned about the Wildlife Technology degree program at Penn State DuBois.
On Sept. 6, the state Department of Environmental Protection added four more counties to its very dry list, bringing the number of counties under drought watch to 38. In those areas, foliage color may turn earlier and be less brilliant than usual, warned Marc Abrams, professor of forest ecology and physiology.
Tyler Wagner, adjunct professor of fisheries ecology in the College of Agricultural Sciences, and Ephraim Hanks, assistant professor of statistics in the Eberly College of Science, will collaborate with researchers at Michigan State University, the University of Wisconsin and the University of Missouri using a new approach to expand traditional ecology to regional and continental scales.
The study was the first field-based test of the relationship between cover-crop species and multifunctionality -- the quality of cover crops to simultaneously provide multiple benefits -- noted research team member Jason Kaye, professor of soil biogeochemistry. Never before had this relationship been examined and analyzed in a crop rotation.
Dennis Brett has been a member of the International Wood Collectors Society for more than 60 years and met Chuck Ray, Penn State associate professor of wood products operations, at a meeting a few years ago. He liked what he heard from Ray, who oversees the Penn State wood collection, housed in the Forest Resources Building.
Free, daily bus tours during the event will take attendees into the field at the surrounding, 2,000-acre Russell E. Larson Agricultural Research Center to learn about projects focusing on topics such as pasture and grazing management, woodlot management, wildlife habitat and biofuel feedstocks.
In a series of high profile journal articles published over the past 30 years, Sridhar Komarneni has explored ways to remove radioactivity from the environment. A materials scientist and Distinguished Professor of Clay Mineralogy, Komarneni develops specially structured synthetic clays capable of immobilizing radioactive species by ion exchange.
The precision of the nutrient-seeking strategies that help trees grow in temperate forests may be related to the thickness of the trees' roots and the type of fungi they use, according to David Eissenstat, professor of woody plant physiology, Penn State. The tree must use a variety of strategies because nutrients often collect in pockets -- or hot spots -- in the soil, he added.
