Patch Burn‐Grazing: An Annotated Bibliography, Rajeeva Voleti, Stephen L. Winter, Sherry Leis

School of Natural Resources: Faculty Publications

Patch burn‐grazing is a rangeland management strategy that exploits the attraction of grazing animals to recently burned areas in order to achieve management objectives. When fire is applied to a landscape in a patchy manner, leaving some patches unburned, the resulting grazing animal activity, forage utilization, and animal impact are patchily distributed within that landscape as well. Areas that have been recently burned tend to be characterized by the highest levels of grazing animal activity while areas that have gone the longest without burning tend to be characterized by the lowest levels of grazing animal activity. This can be advantageous …

On The Challenges Of Modeling The Net Radiative Forcing Of Wetlands: Reconsidering Mitsch Et Al. 2013, Scott C. Neubauer

Biology Publications

Wetlands play a role in regulating global climate by removing carbon dioxide (CO2) from the atmosphere and sequestering it as soil carbon, and by emitting methane (CH4) and nitrous oxide (N2O) to the atmosphere. In a recent article in this journal (Mitsch et al. Landscape Ecol 28:583–597, 2013), CO2 sequestration and CH4 emissions were modeled for several freshwater wetlands that vary in vegetation type, climate, and hydrology. The authors of that study made significant errors that caused them to underestimate the importance of wetland CH4 emissions on climate dynamics. Here, I reanalyze the Mitsch et al. dataset and show that …

Marine Noise Pollution - Increasing Recognition But Need For More Practical Action, Mark P. Simmonds, Sarah J. Dolman, Michael Jasny, E. C. M. Parsons, Lindy Weilgart, Andrew J. Wright, Russell Leaper

Ecology Collection

Over the last two decades, marine noise pollution has become increasingly recognized as an issue of major significance. The issue has become a primary focus of marine mammal research, but is also of concern to the public and policy makers. The result has been efforts involving a variety of disciplines, and relevant legislation and associated guidance are now in place in many parts of the world. Most current mitigation efforts are directed at reducing the risk of injury from exposure to intense noise, although the effectiveness of such mitigation measures in terms of risk reduction has rarely been quantified. Longer-term …

Quantitative Analysis Of Woodpecker Habitat Using High-Resolution Airborne Lidar Estimates Of Forest Structure And Composition, James E. Garabedian, Robert Mcgaughey, Stephen E. Reutebuch, Bernard R. Parresol, John C. Kilgo, Christopher E. Moorman, M. Nils Peterson

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

Light detection and ranging (LiDAR) technology has the potential to radically alter theway researchers and managers collect data onwildlife–habitat relationships. To date, the technology has fostered several novel approaches to characterizing avian habitat, but has been limited by the lack of detailed LiDAR-habitat attributes relevant to species across a continuum of spatial grain sizes and habitat requirements. We demonstrate a novel three-step approach for using LiDAR data to evaluate habitat based on multiple habitat attributes and accounting for their influence at multiple grain sizes using federally endangered red-cockaded woodpecker (RCW; Picoides borealis) foraging habitat data fromthe Savannah River Site (SRS) …

The History And Reintroduction Of Whooping Cranes At White Lake Wetlands Conservation Area, Louisiana, Gay M. Gomez

Proceedings of the North American Crane Workshop

On 16 February 2011, whooping cranes (Grus americana) were reintroduced in the wetlands of southwest Louisiana, after an absence of 61 years. This brief communication provides background on the historical presence of whooping cranes in this region, describes the long road to reintroduction, presents observations from the reintroduction’s first day, and offers thoughts on its future prospects.

On 15 May 1939, biologist John J. Lynch of the U.S. Fish and Wildlife Service observed 13 whooping cranes in the remote freshwater marsh north of White Lake in Vermilion Parish, Louisiana. He not only confirmed what local residents and trappers had long …

Piscataqua Region Environmental Planning Assessment 2015, Piscataqua Region Estuaries Partnership

PREP Reports & Publications

This is the second assessment of land use regulations and planning practices in our watershed, and provides an important understanding of how we are managing our community’s natural resources. Although progress in protecting water quality has been made, management actions are inconsistent across the watershed and even within sub watersheds. In order to protect the places we live, and accommodate growth. It is clear that purposeful coordination and consistency is critical to success in improving water quality and minimizing community costs associated with pollution and impacts from intensifying weather events.

Identifying Priority Conservation Areas For The American Burying Beetle, Nicrophorus Americanus (Coleoptera: Silphidae), A Habitat Generalist, Jessica D. Jurzenski, Christopher F. Jorgensen, Andy Bishop, Roger Grosse, John Riens, W. Wyatt Hoback

United States Fish and Wildlife Service: Publications

Conservation efforts leading to the recovery of the federally endangered American burying beetle (ABB), Nicrophorus americanus Olivier, have been challenging because of the unknown causes of its decline, difficulty in establishing habitat requirements, and unclear population distribution across the species’ range. Extant populations of this widespread generalist species occur in broadly separated regions of North America with varying habitat characteristics. A habitat suitability model for ABB in the Nebraska Sandhills was developed over the course of 3 years resulting in a final cross-validated spatial model. The succession of models from 2009 to 2011 indicated that most of the predictive variables …

Effects Of River Current Inflow On Dissolved Oxygen And Temperature Of Refuge Zones For Cisco In Lake Bemidji, Bryant C. Swenson

Journal of Earth and Life Science

The objectives of this study were to (1) determine if the inflow current from the Mississippi River affects temperature and dissolved oxygen in Lake Bemidji, (2) determine how the amount of suitable cisco Coregonus artedi habitat changes over the summer in Lake Bemidji, and (3) predict how much cisco habitat would be available under a climate warming scenario. Summer fish kill of cisco occurs in most years on Lake Bemidji resulting from low dissolved oxygen in the hypolimnion and high water temperatures in the epilimnion. Dissolved oxygen and temperature profiles provided evidence to suggest the north basin is more suitable …

The Effect Of Barometric Pressure On Feeding Activity Of Yellow Perch, Daniel Vanderweyst

Journal of Earth and Life Science

This is the first study to our knowledge that has attempted to relate feeding activity of fish to barometric pressure. This study was conducted with the expectation that a difference in food ingestion would occur in a game fish species at different barometric pressures. The overall objective of this study is to determine if barometric pressure influences the feeding activity of a popular game fish. Yellow perch (Perca flavescens) were collected by seine and trap net from Lake Bemidji 12 September through 24 October 2013. The range in size and weight of yellow perch used for this study …

Use Of Cast Nets And Seine Hauls To Estimate Abundance Of Age-0 Yellow Perch, Michael Vaske

Journal of Earth and Life Science

Knowledge about fish population dynamics is essential for developing management plans and evaluating management success. In many lakes, yellow perch (Perca flavescens) are the main forage for many upper level predators and recreational fish species. To better manage recreational fisheries, an accurate estimate of prey abundance is necessary. The objectives of the study were to sample the littoral and limnetic zone to better estimate population of age-0 yellow perch, and obtain an estimate of the proportion of yellow perch being missed by traditional littoral seining methods. Littoral seines were conducted at three randomly selected locations in the south …

Changing Body Condition In Walleye With Reference To Ideal Sample Size Requirements, Kevin Longtin

Journal of Earth and Life Science

The objective of this study was to determine if walleye Sander vitreus percent dry weight, a measure of condition, differed among summer months of 2014 on Maple Lake, Minnesota. A second objective was to determine if there was a relationship between condition and body temperature, total length, or wet weight. Between three and six walleyes were collected per month by hook and line methods. All fish had internal body temperatures taken at the time of capture and were oven dried in the laboratory at 80 °C in order to measure percent dry weight. There was no relationship between condition and …
