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.
Sometime between now and the the middle of May, the Pennsylvania Game Commission will complete two prescribed fires within the boundary of the Penn State Stone Valley Forest in northern Huntingdon County. With approval from Penn State's Department of Ecosystem Science and Management, the Game Commission will be conducting these two low-intensity prescribed fires to improve the midstory and understory habitat conditions of the forest area, while providing a field site to demonstrate and display the use and effects of prescribed fires to University students, staff and faculty, as well as the general public.
Penn State students will have their first chance this fall to take a new course on rural road ecology and maintenance, developed by the Center for Dirt and Gravel Road Studies at Penn State’s Thomas D. Larson Pennsylvania Transportation Institute. The course, ERM/FOR 497 Rural Road Ecology & Maintenance, is jointly hosted by the Environmental Resources Management Program and the Department of Ecosystem Science and Management.
Author and researcher Keith Bildstein will recount his study of the ecology of turkey vultures during a free public presentation at Penn State's University Park campus.
The first harvest of 34 acres of fast-growing shrub willow from a Penn State demonstration field this winter is a milestone in developing a sustainable biomass supply for renewable energy and bio-based economic development, according to researchers in Penn State's College of Agricultural Sciences.
Since the 1930s, the composition of forests in the region has changed markedly, according to Marc Abrams, professor of forest ecology and physiology at Penn State. Drought-sensitive, fire-intolerant tree species, such as maple, birch and hemlock, have become more prominent, and drought-resistant, fire-adapted species, such as oak, hickory and pine, have declined.
What would you do without water? Farmers in drought areas are especially concerned by this question. As fresh water resources become scarce, one option for water-conscious farmers is to water crops with treated wastewater. This effluent is becoming a more popular option for applications that don’t require drinking-quality water. However, there are still questions about how the effluent interacts with and affects the rest of the ecosystem.
For Pennsylvanians watching the lead contamination problem in Flint, Michigan, and wondering whether their drinking water is safe, one water-resources specialist at Penn State University says residents with private wells, especially, should consider having their water tested.
The Deer-Forest Study, led by professors Duane Diefenbach and Marc McDill, is a collaborative project among Penn State, the Pennsylvania Game Commission, the Pennsylvania Department of Conservation and Natural Resources, Bureau of Forestry and the Pennsylvania Cooperative Fish and Wildlife Research Unit.
