Evaluations of the local effects of global change are often confounded by the interactions of natural and anthropogenic factors that overshadow the effects of climate changes on ecosystems. Long-term watershed and natural elevation gradient studies at the Hubbard Brook Experimental Forest and in the surrounding region show surprising results demonstrating the effects of climate change on hydrologic variables (e.g., evapotranspiration, streamflow, soil moisture); the importance of changes in phenology on water, carbon, and nitrogen fluxes during critical seasonal transition periods; winter climate change effects on plant and animal community composition and ecosystem services; and the effects of anthropogenic disturbances and …

Divergent Carbon Dynamics Under Climate Change In Forests With Diverse Soils, Tree Species, And Land Use Histories, Robert M. Scheller, Alec M. Kretchun, Steve Van Tuyl, Kenneth L. Clark, Melissa S. Lucash, John Hom

Environmental Science and Management Faculty Publications and Presentations

Accounting for both climate change and natural disturbances—which typically result in greenhouse gas emissions—is necessary to begin managing forest carbon sequestration. Gaining a complete understanding of forest carbon dynamics is, however, challenging in systems characterized by historic over-utilization, diverse soils and tree species, and frequent disturbance. In order to elucidate the cascading effects of potential climate change on such systems, we projected forest carbon dynamics, including soil carbon changes, and shifts in tree species composition as a consequence of wildfires and climate change in the New Jersey pine barrens (NJPB) over the next 100 years. To do so, we used …

Frequent Arousals From Winter Torpor In Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii), Joseph S. Johnson, Michael J. Lacki, Steven C. Thomas, John F. Grider 2012 University of Kentucky

Frequent Arousals From Winter Torpor In Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii), Joseph S. Johnson, Michael J. Lacki, Steven C. Thomas, John F. Grider

Forestry and Natural Resources Faculty Publications

Extensive use of torpor is a common winter survival strategy among bats; however, data comparing various torpor behaviors among species are scarce. Winter torpor behaviors are likely to vary among species with different physiologies and species inhabiting different regional climates. Understanding these differences may be important in identifying differing susceptibilities of species to white-nose syndrome (WNS) in North America. We fitted 24 Rafinesque’s big-eared bats (Corynorhinus rafinesquii) with temperature-sensitive radio-transmitters, and monitored 128 PIT-tagged big-eared bats, during the winter months of 2010 to 2012. We tested the hypothesis that Rafinesque’s big-eared bats use torpor less often than values …


Multi-Stage Novice Defensive Driver Training Program: Does It Create Overconfidence?, Jessica Mueller, Laura Stanley, Kezia R. Manlove 2012 Montana State University

Multi-Stage Novice Defensive Driver Training Program: Does It Create Overconfidence?, Jessica Mueller, Laura Stanley, Kezia R. Manlove

Wildland Resources Faculty Publications

Multi-stage training programs have been recommended to transfer knowledge and skills to high-risk novice drivers. However, some have suggested there is a link between skill training and an increased crash probability due to overconfidence. This project evaluates the outcomes of a multi-phase training system and compares the performance of novice drivers who received second-stage training with that of a control group of novice drivers who received traditional, single-stage training. This trained group and an equivalent group of untrained novice drivers completed annual surveys describing their involvement with traffic citations, near-miss crashes, single-vehicle crashes, and multiple-vehicle crashes. Citation records from the …

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2010, Katherine McGraw, Jennie Popp, Wayne Miller 2012 University of Arkansas, Fayetteville

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2010, Katherine Mcgraw, Jennie Popp, Wayne Miller

AAES Research Reports and Research Bulletins

This report is the seventh in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis (BEA), USDA Economic Research Service (ERS), USDA National Agricultural Statistics Service (NASS), and Minnesota IMPLAN Group, Inc. (MIG), the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2010. Gross Domestic Product (GDP) by State information for Arkansas in 2010 was compared with those of other states in the Southeast U.S. to give a measure of the relative importance of agriculture in Arkansas.2 The total …


Long‐Term Outcomes Of Venus Flytrap (Dionaea Muscipula) Establishment, James O. Luken 2012 Coastal Carolina University

Long‐Term Outcomes Of Venus Flytrap (Dionaea Muscipula) Establishment, James O. Luken

Biology

Determining the success or failure of rare plant establishment requires long-term monitoring, but such monitoring is seldom conducted. A 2004 census of Venus flytrap populations created by seeding and transplanting was compared to a similar census in 2010. Of the 18 original populations, three were destroyed by logging operations, 12 decreased and three increased. Venus flytraps face several limitations keeping populations small. Consistent soil moisture and the presence of population remnants improved the long-term management outcomes.

Geography

Landscape connectivity, the extent to which a landscape facilitates the movements of organisms and their genes, faces critical threats from both fragmentation and habitat loss. Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of reserve networks to potential threats associated with climate change. Loss of connectivity can reduce the size and quality of available habitat, impede and disrupt movement (including dispersal) to new habitats, and affect seasonal migration patterns. These changes can lead, in turn, to detrimental effects for populations and species, …


Too Much Weed: Invasive Species In Chitwan National Park, Laura Nelson 2012 SIT Study Abroad

Too Much Weed: Invasive Species In Chitwan National Park, Laura Nelson

Independent Study Project (ISP) Collection

Invasive plant species threaten jungle eco-systems in Chitwan National Park. Mikania micrantha is the most destructive invasive plant in the park and has been named one of the world’s 100 worst invaders. It is an exceptionally fastgrowing and aggressive perennial plant that is quickly spreading throughout Chitwan and ousting native plant species that comprise the diets of rhinos and other important wildlife species. M. micrantha poses both immediate ecological concerns to wildlife and threatens rural subsistence farming populations by destroying cropland. In Nepal, no policy or program exists to contain invasive plant species, and large-scale management of M. micrantha is …


The Effect Of Increasing Salinity And Forest Mortality On Soil Nitrogen And Phosphorus Mineralization In Tidal Freshwater Forested Wetlands, William Conner, Gregory Noe, B Graeme Lockaby, Ken Krauss 2012 Clemson University

The Effect Of Increasing Salinity And Forest Mortality On Soil Nitrogen And Phosphorus Mineralization In Tidal Freshwater Forested Wetlands, William Conner, Gregory Noe, B Graeme Lockaby, Ken Krauss

Publications

Tidal freshwater wetlands are sensitive to sea level rise and increased salinity, although little information is known about the impact of salinification on nutrient biogeochemistry in tidal freshwater forested wetlands. We quantified soil nitrogen (N) and phosphorus (P) mineralization using seasonal in situincubations of modified resin cores along spatial gradients of chronic salinification (from continuously freshwater tidal forest to salt impacted tidal forest to oligohaline marsh) and in hummocks and hollows of the continuously freshwater tidal forest along the blackwater Waccamaw River and alluvial Savannah River. Salinification increased rates of net N and P mineralization fluxes and turnover in tidal …


The Quantitative Soil Pit Method For Measuring Belowground Carbon And Nitrogen Stocks, Matthew A. Vadeboncoeur, Steven P. Hamburg, Joel D. Blum, Michael J. Pennino, Ruth D. Yanai, Chris E. Johnson 2012 University of New Hampshire

The Quantitative Soil Pit Method For Measuring Belowground Carbon And Nitrogen Stocks, Matthew A. Vadeboncoeur, Steven P. Hamburg, Joel D. Blum, Michael J. Pennino, Ruth D. Yanai, Chris E. Johnson

All Materials

Many important questions in ecosystem science require estimates of stocks of soil C and nutrients. Quantitative soil pits provide direct measurements of total soil mass and elemental content in depth-based samples representative of large volumes, bypassing potential errors associated with independently measuring soil bulk density, rock volume, and elemental concentrations. The method also allows relatively unbiased sampling of other belowground C and nutrient stocks, including roots, coarse organic fragments, and rocks. We present a comprehensive methodology for sampling these pools with quantitative pits and assess their accuracy, precision, effort, and sampling intensity as compared to other methods. At 14 forested …
