A Floristic Survey Of Selected Sites In The Loup River Valley, Nance County, Nebraska, Diane M. Flynn, Steven J. Rothenberger

The Prairie Naturalist

The Loup River Valley of Nebraska contains natural, undisturbed wet meadows with significant plant diversity. Even though these sites are infrequent and are often intermixed with heavily grazed pastures or cultivated fields, they support numerous plant and animal species that do not occur elsewhere. We surveyed three study sites (an ungrazed wet meadow; a grazed wet meadow; and a riparian area) that totaled approximately 68.8 ha during the 2010 and 2011 growing seasons. We compiled an annotated vascular plants checklist for the study area that included 244 plant species of which about 49% (119) were new county records. The mean …

Juvenile Green Sturgeon (Acipenser Medirostris) And White Sturgeon (Acipenser Transmontanus) Behavior Near Water-Diversion Fish Screens: Experiments In A Laboratory Swimming Fume, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue

School of Natural Resources: Faculty Publications

Water diversions that extract fresh water for urban, industrial, and agricultural uses, as well as export to southern California, are prevalent throughout the Sacramento–San Joaquin watershed. Many water diversions are fitted with fish-exclusion screens designed to prevent fish from entrainment (i.e., being drawn in). The impact of fish screens on the behavior of migrating juvenile fishes remains largely unknown, especially for threatened species such as sturgeon. We placed individual juvenile green (Acipenser medirostris) or white (Acipenser transmontanus) sturgeon in a laboratory swimming flume in the presence of standard fish screens (2 mm bar spacing) at two …

Development Of A Public Education Website: Building Bridges Over Water, Angelina Mckee

Agricultural Education and Communication

Website created by Angelina McKee to educate the public about water resource issues. Water is the basic unit of life, water resources are the basis for what societies and ecosystems are founded upon. Water shortages and droughts are more prevalent in our ever-changing world. It is no shock that there are discrepancies between various stockholders on either sides of the dry riverbed. This senior project resulted in the development of a website that addresses global water resources, water use in California, water conservation, and water allocation. The website informs the public on water resources and related issues and will hopefully …

A Win-Win On Agricultural Lands: Creating Wildlife Habitat Through Agroforestry, Gary Bentrup

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

With increasing demands from society for limited resources, agroforestry will likely be one source of solutions as people find it increasingly necessary to achieve multiple social, economic, and ecological objectives on the same plot of land. Indications are that this is a growing field, so wildlife biologists of the future may want to consider incorporating agroforestry into their career development.

The Effects Of Radar On Avian Behavior: Implications For Wildlife Management At Airports, Eleanor R. Sheridan

Open Access Theses

Airports are areas with a high availability of resources for wildlife to forage, breed, and roost. Airports also have different types of radars to assist with air traffic control as well as tracking of wildlife that could become a risk for aircraft. The effect of radar electromagnetic radiation on wildlife behavior is not well understood. The goal of this study was to determine if bird behavior is affected by radar in two contexts: static radar (e.g., surveillance radar) and approaching radar (e.g., aircraft weather radar). We used brown-headed cowbirds as a model species. In the static radar context, we performed …

Variation In Habitat Thresholds: An Analysis Of Minimum Habitat Requirements Of North American Breeding Birds, Yntze Van Der Hoek

Dissertations, Theses, and Capstone Projects

Many species show dramatic changes in population extinction or persistence probability at particular habitat amounts. These `extinction thresholds' could be translated to conservation targets, under the condition that we can derive generalities. I investigated the level of variation in landscape-level habitat thresholds for a suite of North American, forest-associated, breeding birds. Records from Breeding Bird Atlases and the availability of remotely-sensed land cover data allowed me to compare habitat thresholds for 25 species across the states of Massachusetts, Michigan, New York, Ohio, Pennsylvania, and Vermont. I show that variation in thresholds is considerable (Chapter II, III), as thresholds range from …

Patch-Burn Grazing Effects On Cattle Performance: Research Conducted In A Working Landscape, Stephen L. Winter, Samuel D. Fuhlendorf, Mark Goes

School of Natural Resources: Faculty Publications

• Patch-burn grazing is a range management strategy that might be able to simultaneously optimize livestock production objectives and wildlife habitat objectives.

• We compared patch-burn grazing to a traditional range management strategy in multiple pastures, representing a variety of land ownership and management histories, dispersed across a relatively large geographic area. Our results likely represent what land managers could expect if they adopted patch-burn grazing in similar situations.

• We found that cattle performance in pastures managed with patch-burn grazing did not differ from that found in pastures managed with a traditional range management strategy. This suggests that land …

Multi-Scale Habitat Use Of Male Ruffed Grouse In The Black Hills National Forest, Cassandra L. Mehls, Kent C. Jensen, Mark A. Rumble, Michael C. Wimberly

The Prairie Naturalist

Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (Black Hills). Our objective was to assess resource selection of male ruffed grouse to identify the most appropriate scale to manage for aspen and ruffed grouse in the Black Hills. During spring 2007 and 2008, we conducted drumming surveys throughout the central and northern Black Hills to locate used and unused sites from which we compared habitat characteristics at increasing spatial scales. Aspen with >70% overstory canopy cover (OCC) was important to the occurrence of …

Sauger Life History In The Lower Portion Of The Upper Mississippi River, Kasey L. Yallaly, Justin R. Seibert, Sara J. Tripp, David P. Herzog, Quinton E. Phelps

The Prairie Naturalist

Widespread declines have been observed in numerous riverine fish species due to a host of anthropogenic related perturbations such as channelization, dam creation, and exploitation (Graham 1997, Gerken and Paukert 2009). Understanding life history and population demographics of riverine fishes is critical to their conservation. Specific to our study, the Mississippi River has undergone extensive habitat modifications that have changed the Upper Mississippi River (UMR) from a typical lotic large, free flowing river to multiple reservoir-like pools with reduced flow (LePage 1980, Hurley et al. 1987). These habitat transformations may impact sauger (Sander canadensis) populations within the Mississippi River. Several …

Den Characteristics Of Upland And Low- Land Striped Skunks Along The Missouri River Floodplain, Dave Sempek, James A. Wilson

The Prairie Naturalist

Striped skunks (Mephitis mephitis) are opportunistic with respect to habitat use (Bixler and Gittleman 2000), inhabiting an array of landscapes in the proximity of a permanent water supply, such as forest borders, old-fields, fencerows, and open grassy fields broken by wooded ravines (Schwartz and Schwartz 1981, Larivière and Messier 2000). Food quantity and accessibility are major factors determining the quality of striped skunk habitat (Larivière et al. 1999) and are important in the den site selection.

Dens play an important role in skunk survival and reproduction due to the warmth, predator protection, and safe location for parturition they provide (Hwang …

Notes: Bed-Site Selection By Neonatal White-Tailed Deer In Central North Dakota, Brian A. Schaffer, Jonathan A. Jenks, Troy W. Grovenburg, William F. Jensen

The Prairie Naturalist

Understanding bed-site selection and vegetation characteristics provides valuable information for population management (Verme 1977, Huegel et al. 1985a, Nelson and Woolf 1987). Predation and other natural-caused mortalities of white-tailed deer (Odocoileus virginianus) neonates are most likely to occur within the first 60 days of life; a time period when selected habitat characteristics are vital to survival (Verme 1977, Hue- gel et al. 1985a, Nelson and Woolf 1987, Grovenburg et al. 2010). Prior to the study of Grovenburg et al. (2010), limited research had been completed on the bed-site selection of neonatal white-tailed deer in the grasslands of the Northern Great …

Precipitation And Fire Impacts On Small Mammals In Shortgrass Prairie, Whitney J. Priesmeyer, Raymond S. Matlack, Richard T. Kazmair

The Prairie Naturalist

The southern Great Plains and the northern part of the Texas Panhandle have received less attention from a biological perspective than other parts of the state. Although there is substantial information on the effects of fire on small mammals in the tallgrass and mixed-grass prairies, there is a lack of understanding of fire influences in the shortgrass prairie, specifically on small mammals. We conducted our study on the Cross Bar Cooperative Management Area (CMA), a 4,856 ha shortgrass prairie within the Texas panhandle. Our objective was to determine the effect of three different fire return frequencies and precipitation on diversity …

Bobcat Predation On Bighorn Lamb In The Western Black Hills Of South Dakota, Brynn L. Parr, John Kanta, Joe Sandrini, Daniel J. Thompson, Jonathan A. Jenks

The Prairie Naturalist

Bighorn sheep (Ovis canadensis) are found throughout western North America (Krausman et al. 1993, Goodson 1994, Krausman et al. 1996, Besser et al. 2012). In their current range, commonly documented large predators of bighorn sheep include cougars (Puma concolor), gray foxes (Urocyon cinereoargenteus), wolves (Canis lupus), and coyotes (C. latrans; Ross et al. 1997, Neale et al. 1998, Corti and Shackleton 2002, Dekker 2009, Karsch et al. 2013). Bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) also have been documented as predators to both wild and domestic sheep (Kennedy 1948, Cunningham 1970, Nette et al. 1984, Watte and Phillips …

The Role Of Reviewer Criticism And How To Keep It In Perspective, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! Hopefully this editorial finds you well and gearing up for the summer field season. As I write this editorial, I find myself reflecting on my time as Editor-in-Chief of TPN over the past 5 years. The experience has been personally and professionally rewarding in many ways, and I want to spend some time discussing something that I have experienced not only as a fellow author and Associate Editor, but also as a journal Editor.

Reviewer criticism. Thinking back to when I was appointed Editor, how I viewed criticism then is very different than how I think about …

The Gamekeepers: Wisconsin Wildlife Conservation From Wcd To Cwd. David L. Gjeston., Carrol L. Henderson

The Prairie Naturalist

Author David L. Gjeston has done a masterful job of capturing the history of wildlife conservation and, in particular, the work of the Wisconsin Department of Natural Resources (formerly the Wisconsin Conservation Department or WCD) in protecting, restoring, and managing the wildlife resources of Wisconsin. Gjeston took on an incredibly complex task. He tells a fascinating story of wildlife conservation comprised of many layers of wildlife management from over a century and a half of evolving perceptions regarding wildlife uses, exploitation, restoration, problems, conflicts, and recreational opportunities that continue to the present.

Perhaps the most appealing part of this book …

Quantifying Differences In Habitat Use Between Anglers And Large Bluegills, Eric J. Weimer, Michael L. Brown, Brian G. Blackwell

The Prairie Naturalist

We compared the habitat use of large (>200 mm) bluegills (Lepomis macrochirus) to the locations of anglers targeting bluegills in a South Dakota glacial lake to determine whether habitat use was similar between anglers and bluegills. Eighty- five bluegills (mean total length = 213 mm) collected in September 2002 and May 2003 were affixed with external radio transmitters and subsequently relocated three to four times per week from October 2002 through October 2003. Bluegill angler locations were recorded during bluegill tracking sessions and roving creel surveys. Habitat variables (water depth, vegetation density and height, and substrate type) were measured …

Making Nature Whole: A History Of Ecological Restoration. William R. Jordan Iii And George M. Lubick., Daryl D. Smith

The Prairie Naturalist

Ecological restoration—the process of assisting the recovery of ecosystems that have been degraded, damaged, or destroyed—is being incorporated into the fabric of our society. The practice of ecological restoration of natural areas developed and grew in the twentieth century in response to widespread human disturbance of natural communities. Undoubtedly, this type of restoration will continue to increase in importance in the coming decades given the extensive alteration of ecosystems that is occurring and that is showing no signs of abating.

As indicated in the promotional material for Making Nature Whole, Jordan and Lubick have provided a seminal publication for the …

Mammals Of North Dakota. First Edition. Robert Seabloom., Erin H. Gillam

The Prairie Naturalist

As a mammalogist living in the Great Plains, I was excited to hear about the publication of The Mammals of North Dakota by Robert Seabloom. No such field guide has been compiled since the late 1920s, leaving nature lovers and researchers alike without a modern source of information about the mammals of the state. Despite my enthusiasm, I will admit that I was originally expecting a standard (i.e., boring) field guide with dry facts about the taxonomic groups of interest. Much to my surprise, this book was not a mere list of relevant information, but an engaging work providing extensive …

Diurnal Raptors Of Buffalo County, Nebraska, Thomas L. Freeman

The Prairie Naturalist

Diurnal birds of prey are apex predators, which often are utilized as indicators of potential environmental change (Newton 1979, Rodriguez-Estrella et al. 1998). While the Platte River Valley of Nebraska and the central plains are recognized as important winter habitat for numer- ous bird of prey species (United States Fish and Wildlife Service [USFWS] 1981, Root 1988), there are few published studies describing the distribution and abundance of raptors in Nebraska (Mathisen and Mathisen 1968, Craighead and Craighead 1969, USFWS 1981). In addition, studies summarizing the long-term distribution or density of Falconi- formes in Nebraska are limited due to the …

Book Review: The Iowa Lakeside Laboratory: A Century Of Discovering The Nature Of Nature. Michael J. Lannoo., Bonnie S. Bowen

The Prairie Naturalist

Iowa Lakeside Laboratory (a.k.a. Lakeside Lab) is one of several biological field stations that were established in the early 1900s and that have active educational and research programs today. Michael Lannoo’s account of the history of Lakeside Lab was initiated at the centennial celebration of the lab in 2009. Lannoo’s own connection with Iowa Lakeside Laboratory began as a student at Iowa State University and continues today as a member of the Lakeside Lab summer faculty and as Associate Director of Academics and Research. In his book, Lannoo describes field stations, and Lakeside Lab in particular, as educational institutions that …

Book Reviews: Video Surveillance Of Nesting Birds. Edited By Christine A. Ribic, Frank R. Thompson Iii, And Pamela J. Pietz., Marissa A. Ahlering

The Prairie Naturalist

Observations and studies of nests have been a central component of ornithology since its inception. Until recently, studies of nesting ecology were limited to human observation, making some types of information nearly impossible to obtain, such as nocturnal behavior, or difficult to study with adequate sample sizes, such as provisioning behaviors or cause of nest failure. The use of video photography to study the nesting biology of birds has exploded in the past decade, and the most recent volume of Studies in Avian Biology, Video Surveillance of Nesting Birds, has done a nice job of summarizing the history of camera …

Mate Replacement And Alloparental Care In Ferruginous Hawk (Buteo Regalis), Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent C. Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg

The Prairie Naturalist

Alloparental care (i.e., care for unrelated offspring) has been documented in various avian species (Maxson 1978, Smith et al. 1996, Tella et al. 1997, Lislevand et al. 2001, Literak and Mraz 2011). A male replacement mate that encounters existing broods has options, which include alloparental care or infanticide. Infanticide may be beneficial in some species (Rohwer 1986, Kermott et al. 1990), but in long-lived avian species, like the ferruginous hawk (Buteo regalis) that do not renest within a season, infanticide might be detrimental. Adoption and rearing success likely provide direct evidence of competence of replacement mates as potential parents for …

Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker

2014 Student Theses

Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication …

Macroinvertebrate Assemblages and Dynamic Soil Properties: Influence of Dredging: Abstract

The habitat characterization of subaqueous soils is important for inventorying natural resources and monitoring changes in ecosystem processes. This project aimed to characterize benthic communities within coastal ponds of southern Rhode Island, and develop an understanding of how these communities change due to habitat alterations. I explored the distribution of benthic biology among a range of estuarine subaqueous soils and the effect of anthropogenic disturbance (dredging) on these distributions. The term “benthic” refers to the collection of organisms living in the substrate at the interface …

Effects Of Petroleum Distillates On Amphibian Development, Kate Walker

Graduate Theses and Dissertations

Petroleum distillates are widely used as an energy source and the extraction and disposal of these chemicals are done with little consideration of their effects on aquatic environments. Amphibians are considered excellent ecological indicators but little research has examined effects of petroleum distillates on aquatic species. I evaluated the lethal and sublethal effects on larval amphibians with exposure to petroleum distillates associated with various venues of pollution including hydraulic fracturing. I selected three petroleum distillates (kerosene, oil, and unleaded gasoline) that are known to have negative effects on aquatic organisms and are similar to the common constituents of mixtures used …

Spreading The Char: The Importance Of Local Compatibility In The Diffusion Of Biochar Systems To The Smallholder Agriculture Community Context, Laura C. V. Munoz

Pomona Senior Theses

This thesis enters the context of smallholder agriculture communities in the developing world. It explores the potentials of biochar and what biochar systems could bring to the smallholder communities while simultaneously bringing environmental benefits. It then acknowledges the challenges of diffusion –the spreading of an unfamiliar innovation. It seeks to answer the question of what will make diffusion of biochar systems more successful in the smallholder context, fixating on the characteristic of compatibility as well as the role local community members can play in making a new biochar system more visible to the rest of the communities.

Pronghorn (Antilocapra Americana) Offspring Recruitment On The Carrizo Plain National Monument: Evaluating The Effects Of Low Population Density And Marginal Habitat Quality., Diego Ramirez Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Demographic fluctuation among ungulate populations is strongly linked to variability in recruitment. Rates of recruitment are subject to various forms of density-dependent and density-independent regulation. For species which benefit from the presence of conspecifics, reduced population density can decrease rates of recruitment and trigger a decline in per capita growth. Termed the Allee effect, this scenario can cause demographic collapse and population extinction. For many ungulate species, predation on juveniles is reduced when the timing and distribution of births is synchronized within a local population. Because birth synchrony is density-dependent, it may act as a mechanism for the Allee effect …

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni

Environment and Sustainability Honors Papers

Forests in Southeastern Pennsylvania have been shaped by a number of anthropocentric factors over the past century, with many areas experiencing a recent trend towards forest recovery. Studies on forest dynamics have shown that most developed regions exhibit a forest transition, which begins when land is cleared for natural resource extraction (e.g., agriculture, forestry) during an early development stage. Then as a population grows and food production needs are met, rural peoples begin to migrate to the city, and a feeling of scarcity of trees develops that may lead to changes in land management attitudes, and many formerly deforested areas …

Using Deuterium And Garp To Estimate Geographic Extents Of Source Populations Of Hoary ( Lasiurus Cinereus ) And Eastern Red ( Lasiurus Borealis ) Bats Killed At A Central Illinois Wind Facility, Rachael Anne Van Essen

Theses and Dissertations

High bat mortality at wind energy facilities is a widely cited conservation issue, but the population-level impacts are not understood. In Illinois, the main species affected are migratory tree bats like the Hoary (Lasiurus cinereus) and Eastern Red (Lasiurus borealis).This research used deuterium isotope analysis of hair combined with ecological niche modeling (GARP: Genetic Algorithm for Rule-set Prediction) in a novel way to map the geographic extents of Hoary and Eastern Red bat specimens salvaged at a single central Illinois wind facility from 2008-2010. Hair was chosen after determining that the claw is currently a problematic tissue due to a …
