Variation In Regional And Landscape Effects On Occupancy Of Temperate Bats In The Southeastern U.S., Benjamin D. Neece, Susan C. Loeb, David S. Jachowski

Publications

Habitat loss, wind energy development, and the disease white-nose syndrome are major threats contributing to declines in bat populations in North America. In the southeastern US in particular, the recent arrival of white-nose syndrome and changes in landscape composition and configuration have driven shifts in bat species populations and distributions. Effective management strategies which address these large-scale, community-level threats require landscape-scale analyses. Our objective was to model the relationship between ecoregional and landscape factors and occupancy by all bat species in South Carolina, USA, during summer. We conducted acoustic surveys from mid-May through July 2015 and 2016 and evaluated temporally …

Ponderosa Pine Seedling Physiology After Severe Wildfire: Does It Take A Forest To Make A Forest?, Lauren Bansbach

Shared Knowledge Conference

Ponderosa pine forests are an iconic ecosystem of western North America and provide numerous ecological, economic, and cultural benefits. Historically, these forests experienced regular surface fires that left most large, mature trees surviving. However, suppression of wildfires along with a warming climate have led to catastrophic tree-killing fires that result in vast areas (>200 mi2) dominated by shrubs and grasses. Because of limited survival of tree seedlings in these post-fire habitats, it remains unknown whether ponderosa pines can successfully recolonize severely burned landscapes. Without a mature tree canopy to provide periodic shade, seedlings experience hotter, drier conditions and likely …

Improving Ecological Restoration To Curb Biotic Invasion—A Practical Guide, Qinfeng Guo, Dale G. Brockway, Diane L. Larson, Deli Wang, Hai Ren

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Common practices for invasive species control and management include physical, chemical, and biological approaches. The first two approaches have clear limitations and may lead to unintended (negative) consequences, unless carefully planned and implemented. For example, physical removal rarely completely eradicates the targeted invasive species and can cause disturbances that facilitate new invasions by nonnative species from nearby habitats. Chemical treatments can harm native, and especially rare, species through unanticipated side effects. Biological methods may be classified as biocontrol and the ecological approach. Similar to physical and chemical methods, biocontrol also has limitations and sometimes leads to unintended consequences. Therefore, a …

Microbial Diversity In Urban Environments: Concern For Antibiotic Resistance, Ality Aghedo, Mangala Tawde, Nazrul I. Khandaker

Publications and Research

We are almost oblivious to the presence of microorganisms in our daily lives, but they exist and come into contact with us all the time. While some bacteria are harmless, and even beneficial, other bacteria can cause infections. A common treatment to bacterial infections is antibiotics and the success of an antibiotic depends on the resistance of the bacteria to the antibiotic. We conducted experiments to identify the types of bacteria that can be found on surfaces or within soil environments that come into contact with a vast number of people on a daily basis and how this can affect …

Demographics, Experiences, And Management Preferences Of Backcountry Campers In Yellowstone National Park, Ryan P. Grisham

Electronic Theses and Dissertations

A questionnaire was distributed to backcountry campers in Yellowstone National Park for the summer of 2016. Upon registering for a backcountry camping permit, park rangers asked if campers would like to participate in the survey, which included questions regarding demographics and opinions on visitor experiences and management policies. Participants provided their names and email address and were sent a link to the questionnaire about two weeks after their trip. The survey was a partial replication of a study by Tim Oosterhous conducted in 1999 and results for both years were analyzed and compared to identify any changes in backcountry use …

Spatial Factor Models For High-Dimensional And Large Spatial Data: An Application In Forest Variable Mapping, Daniel Taylor-Rodríguez, Andrew O. Finley, Abhirup Datta, Chad Babcock, Hans-Erik Andersen, Bruce D. Cook, Douglas C. Morton, Sudipto Banerjee

Mathematics and Statistics Faculty Publications and Presentations

Gathering information about forest variables is an expensive and arduous activity. As such, directly collecting the data required to produce high-resolution maps over large spatial domains is infeasible. Next generation collection initiatives of remotely sensed Light Detection and Ranging (LiDAR) data are specifically aimed at producing complete-coverage maps over large spatial domains. Given that LiDAR data and forest characteristics are often strongly correlated, it is possible to make use of the former to model, predict, and map forest variables over regions of interest. This entails dealing with the high-dimensional (∼10² ) spatially dependent LiDAR outcomes over a large number …

The Importance Of Small Fire Refugia In The Central Sierra Nevada, California, Usa, Erika M. Blomdahl, Crystal A. Kolden, Arjan J.H. Meddens, James A. Lutz

Wildland Resources Faculty Publications

Fire refugia – the unburned areas within fire perimeters – are important to the survival of many taxa through fire events and the revegetation of post-fire landscapes. Previous work has shown that species use and benefit from small-scale fire refugia (1 m² to 1000 m²), but our understanding of where and how fire refugia form is largely limited to the scale of remotely sensed data (i.e., 900 m² Landsat pixels). To examine the causes and consequences of small fire refugia, we field-mapped all unburned patches ≥1 m² within a contiguous 25.6 ha forest plot that …

Beyond The 1984 Perspective: Narrow Focus On Modern Wildfire Trends Underestimates Future Risks To Water Security, Brendan P. Murphy, Larissa L. Yocom, Patrick Belmont

Ecology Center Publications

The western United States remains well below historical wildfire activity, yet misconceptions abound in the public and news media that the area burning by wildfire each year in the American West is unprecedented. We submit that short‐term records of wildfire and a disproportionate focus on recent fire trends within high‐profile science stoke these misconceptions. Furthermore, we highlight serious risks to long‐term water security (encompassing water supply, storage, and quality) that have only recently been recognized and are underestimated as the result of skewed perspectives of wildfire. Compiling several data sets, we illustrate a comprehensive history of western wildfire, demonstrate that …

Assessing Ecosystem Services From The Forestry-Based Reclamation Of Surface Mined Areas In The North Fork Of The Kentucky River Watershed, Kumari Gurung, Jian Yang, Lei Fang

Forestry and Natural Resources Faculty Publications

Surface mining is a major driver of land use land cover (LULC) change in many mountainous areas such as the Appalachian region. Typical reclamation practices often result in land cover dominated by grass and shrubs. Assessing ecosystem services that can be obtained from a forest landscape may help policy-makers and other stakeholders fully understand the benefits of forestry-based reclamation (FRA). The objectives of this study are to (1) identify how surface mining and reclamation changed the LULC of a watershed encompassing the north fork of the Kentucky River, (2) assess the biophysical value of four major ecosystem services under the …

Mule Deer Impede Pando’S Recovery: Implications For Aspen Resilience From A Single-Genotype Forest, Paul C. Rogers, Darren J. Mcavoy

Ecology Center Publications

Aspen ecosystems (upland Populus-dominated forests) support diverse species assemblages in many parts of the northern hemisphere, yet are imperiled by common stressors. Extended drought, fire suppression, human development, and chronic herbivory serve to limit the sustainability of this keystone species. Here we assess conditions at a renowned quaking aspen (Populus tremuloides) grove—purportedly the largest living organism on earth—with ramifications for aspen biogeography globally. The “Pando” clone is 43 ha and estimated to contain 47,000 genetically identical aspen ramets. This iconic forest is threatened in particular by herbivory, and current management activities aim to reverse the potential for …

Manipulation Of Growth And Architectural Characteristics In Trees For Increased Woody Biomass Production, Victor B. Busov

Michigan Tech Publications, Part 1

Growth and architectural traits in trees are economically and environmentally important and thus of considerable importance to the improvement of forest and fruit trees. These traits are complex and result from the operation of a number of molecular mechanisms. This review will focus on the regulation of crown architecture, secondary woody growth and adventitious rooting. These traits and processes have significant impact on deployment, management, and productivity of tree crops. The majority of the described work comes from experiments in model plants, poplar, apple, peach, and plum because these species allow functional analysis of the involved genes and have significant …

Contemporary Sunday Hunting Laws: Unnecessary Economic Roadblocks, Ripe For Repeal, Seamus Ovitt

William & Mary Environmental Law and Policy Review

In America, Sunday closing laws, laws restricting what activities individuals could engage in, date back to the early colonial period; those early laws, like much of North American jurisprudence, trace their roots to the laws that existed in England at the time. Historically, however, laws restricting the behavior of individuals, specifically on Sundays, date back thousands of years; initially, their language was tied directly to that of the Old Testament. As God declared:

[s]ix days shalt thou labour, and do all thy work: But the seventh day [is] the Sabbath of the Lord thy God: [in it] thou shalt not …

The Hydrologic Role Of Urban Green Space In Mitigating Flooding (Luohe, China), Tian Bai, Audrey L. Mayer, William D. Shuster, Guohang Tian

College of Forest Resources and Environmental Science Publications

Even if urban catchments are adequately drained by sewer infrastructures, flooding hotspots develop where ongoing development and poor coordination among utilities conspire with land use and land cover, drainage, and rainfall. We combined spatially explicit land use/land cover data from Luohe City (central China) with soil hydrology (as measured, green space hydraulic conductivity), topography, and observed chronic flooding to analyze the relationships between spatial patterns in pervious surface and flooding. When compared to spatial–structural metrics of land use/cover where flooding was commonly observed, we found that some areas expected to remain dry (given soil and elevation characteristics) still experienced localized …

A Genetic Network Mediating The Control Of Bud Break In Hybrid Aspen, Rajesh Kumar Singh, Jay P. Maurya, Abdul Azeez, Pal Miskolczi, Szymon Tylewicz, Katja Stojkovic, Nicolas Delhomme, Victor Busov, Rishikesh P. Bhalerao

Michigan Tech Publications, Part 1

In boreal and temperate ecosystems, temperature signal regulates the reactivation of growth (bud break) in perennials in the spring. Molecular basis of temperature-mediated control of bud break is poorly understood. Here we identify a genetic network mediating the control of bud break in hybrid aspen. The key components of this network are transcription factor SHORT VEGETATIVE PHASE-LIKE (SVL), closely related to Arabidopsis floral repressor SHORT VEGETATIVE PHASE, and its downstream target TCP18, a tree homolog of a branching regulator in Arabidopsis. SVL and TCP18 are downregulated by low temperature. Genetic evidence demonstrates their role as negative regulators …

Mid-Atlantic Forest Ecosystem Vulnerability Assessment And Synthesis: A Report From The Mid-Atlantic Climate Change Response Framework Project, Patricia Leopold, Louis Iverson, Frank R. Thompson Iii, Leslie A. Brandt, Stephen D. Handler, Danielle Shannon, Matt Kelly, Et. Al.

College of Forest Resources and Environmental Science Publications

Forest ecosystems will be affected directly and indirectly by a changing climate over the 21st century. This assessment evaluates the vulnerability of 11 forest ecosystems in the Mid-Atlantic region (Pennsylvania, New Jersey, Delaware, eastern Maryland, and southern New York) under a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and described a range of projected future climates. This information was used to parameterize and run multiple forest impact models, which provided a range of potential tree responses to climate. Finally, we brought these results before two multidisciplinary panels of …
