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.
Fewer female white-tailed deer disperse than males, but when they do, they typically travel more than twice as far, taking much more convoluted paths and covering larger areas. These findings have important deer-management implications in states where chronic wasting disease is known to be infecting wild, free-ranging deer, noted researcher Duane Diefenbach, adjunct professor of wildlife ecology.
Even though amphibian populations are declining sharply worldwide, there is no smoking gun to indicate a cause and thus no simple solution to halting or reversing these declines.
Despite the highly publicized lead contamination in the municipal water supply serving Flint, Michigan, the vast majority of public water systems meet federal safe drinking water standards. However, the same cannot be said for private supplies -- such as wells, springs and cisterns -- in Pennsylvania, according to Bryan Swistock, water resources extension specialist in Penn State's College of Agricultural Sciences.
Forty people including students, faculty, and alumni donated their time to improve the Penn State Mont Alto Arboretum during the “Every Day is Arbor Day” event on April 22.
Efforts to sustain and increase wildlife species at an area lake are picking up this spring with a great deal of help from students in the Penn State DuBois wildlife technology program.
Penn State Mont Alto to hold annual trauma training exercise for forest technology and nursing students
Tyler Wagner, adjunct professor of fisheries ecology, recently received an Excellence in Science Award from the U.S. Geological Survey for outstanding research.
