Who Else Would Plant The Trees? A Status Update On The Pemba Flying Fox, Hannah “Hawa” Grose, Catherine Grace “Rahma” Clemmens

Independent Study Project (ISP) Collection

This study assesses the current population of Pemba Flying Fox, Pteropusvoeltzkowi, at four key locations on Pemba Island off the coast of Tanzania previously noted as highly populated roost sites: Ngezi National Forest, Wete, Kidike, and MsituwaMbiji. We evaluate local knowledge, perceptions, and practices of communities surrounding the Pemba Flying Fox. This study also documents roosting and migratory patterns of the bats. We hypothesize a growth in bat population, an overall positive community perception of the bats, and a greater amount of conflict between fruit farmers and Pteropusvoeltzkowi. Results showed a decrease in estimated population. Additionally, reverse correlation was found …

Fecal Near Infrared Spectroscopy To Discriminate Physiological Status In Giant Pandas., Erin E. Wiedower, Andrew J. Kouba, Carrie K. Vance, Rachel L. Hansen, Jerry W. Stuth, Douglas R. Tolleson

CALS Publications

Giant panda (Ailuropoda melanoleuca) monitoring and research often require accurate estimates of population size and density. However, obtaining these estimates has been challenging. Innovative technologies, such as fecal near infrared reflectance spectroscopy (FNIRS), may be used to differentiate between sex, age class, and reproductive status as has been shown for several other species. The objective of this study was to determine if FNIRS could be similarly used for giant panda physiological discriminations. Based on samples from captive animals in four U.S. zoos, FNIRS calibrations correctly identified 78% of samples from adult males, 81% from adult females, 85% from adults, 89% …

Monitoring Standing Herbage Of Mid-Grass Prairie On The Fort Pierre National Grassland, South Dakota, Daniel W. Uresk

The Prairie Naturalist

Monitoring vegetation with a modified Robel pole on the Fort Pierre National Grassland was evaluated for combined shallow clay and loamy overflow ecological sites (dominated by warm-season grasses), and for clayey ecological sites (dominated by cool-season grasses). My objectives were to 1) develop a relationship between visual obstruction readings (VOR) and standing herbage, 2) provide guidelines for vegetation monitoring, and 3) evaluate vegetation monitoring during the growing season for clayey ecological sites. The relationship between visual obstruction readings and standing herbage was linear and regression coefficients were highly significant (P < 0.001) for both ecological types. Cluster analyses for shallow clay and loamy overflow ecological sites grouped the VOR and standing herbage (kg•ha-1) into 4 resource categories. Monitoring with 4 transects will provide adequate information to estimate standing herbage within 259 ha (1 section). Three resource categories (VOR + herbage) for clayey ecological sites were defined by cluster analyses. Monitoring with 4 transects was determined to provide reliable estimates of standing herbage. July validation of vegetation with the developed clayey ecological site model will provide reliable monitoring of standing herbage from July through November for this ecological site.

Germination Response Of Prairie Dropseed And Hairy Goldaster To Stratification And Temperature, Aurora R. Roemmich, Jack L. Bulter, Gary E. Larson, E. Brent Turnipseed

The Prairie Naturalist

The unique vegetation assemblage of the Black Hills in conjunction with the frequent occurrence of natural and anthropogenic disturbances emphasizes the need to use locally adapted native species in a wide variety of restoration efforts. However, a general lack of information regarding germination and propagation requirements for most native plant species has restricted their usage. A better understanding of dormancy and germination patterns for native species will increase their availability and affordability. We selected two common native species, hairy goldaster (Heterotheca villosa) and prairie dropseed (Sporobolus heterolepis), to determine their optimum germination conditions. We hand-harvested seeds during 2007–2009 for use …

Review: Mammals Of Colorado. Second Edition. David M. Armstrong, James P. Fitzgerald, And Carron A. Meaney., Thomas J. O'Shea

The Prairie Naturalist

In my view, the second edition of Mammals of Colorado is among the finest state-level books on mammals available. The book is a major revision of the first edition (Fitzgerald et al. 1994) and is a reference worth having, even if the first edition is already at hand. In this review, T summarize aspects of the new volume and provide comparisons to the first edition in an effort to persuade the reader that this is indeed the case.

The first four chapters of the second edition include background information and updated material about Colorado environments, mammals in general, the history …

Five New Records Of Ants (Hymenoptera: Formicidae) For Nebraska, Kristine T. Nemec, James C. Trager, Elizabeth Manley, Craig R. Allen

The Prairie Naturalist

Ants are ubiquitous and influential organisms in terrestrial ecosystems. About 1,000 ant species occur in North America, where they are found in nearly every habitat (Fisher and Cover 2007). Ants are critical to ecological processes and structure. Ants affect soils via tunneling activity (Baxter and Hole 1967), disperse plant seeds (Lengyel et al. 2009), prey upon a variety of insects and other invertebrates (Way and Khoo 1992, Folgarait 1998), are often effective primary consumers through their prodigious consumption of floral and especially extrafloral nectar, and honeydew (Tobin 1994), and serve as prey for invertebrates (Gotelli 1996, Gastreich 1999) and vertebrates …

Microhabitat Selection By Bobcats In The Badlands And Black Hills Of South Dakota, Usa: A Comparison Of Prairie And Forested Habitats, Cory E. Mosby, Troy W. Grovenburg, Robert W. Klaver, Greg M. Schroeder, Lowell E. Schmitz, Jonathan A. Jenks

The Prairie Naturalist

An understanding of habitat selection is important for management of wildlife species. Although bobcat (Lynx rufus) resource selection has been addressed in many regions of the United States, little work has been conducted in the Northern Great Plains. From 2006–2008 we captured and radiocollared 20 bobcats in the Badlands (n = 10) and Black Hills (n = 10) regions of South Dakota. During the summers of 2008 and 2009 we collected habitat measurements at 349 (176 Badlands, 176 Black Hills) bobcat locations and 321 (148 Badlands, 173 Black Hills) random sites. Microhabitat characteristics at bobcat use sites varied with region …

Distribution And Diversity Of Ant Genera From Selected Ecoregions Across Nebraska, Jessica Jurzenski, Marc Albrecht, W. Wyatt Hoback

The Prairie Naturalist

We documented distribution and diversity of ant genera in four of the six-level III ecoregions across Nebraska. We sampled ants using bait cards, pitfall traps, and by opportunistic sampling, including direct collection and in carrion-baited pitfall traps. We identified 22 genera from five subfamilies, which were further classified into six functional groups. In common with other Great Plains states, Formica Linnaeus and Lasius Fabricius occurred most frequently in our samples, and overall ant genus-level richness was comparable to surrounding states. We compared genera similarity using Jaccard’s similarity index within and between the High Plains (western-most) and Western Corn Belt Plains …

Book Reviews: Human Dimensions Of Ecological Restoration: Integrating Science, Nature, And Culture. Edited By Dave Egan, Evan E. Hjerpe, And Jesse Abrams., Chuck Harris

The Prairie Naturalist

The practice of ecological restoration has long been a key element in the management of ecosystems, but it has only been since the 1980s that research on resource management has specifically studied this practice and its foundations in restoration ecology. One major focus of this research has been the application of the theories and methods of the social sciences to ecological restoration activities.

Fairly recently, the application of the social sciences to resource management, in general, and to ecological restoration, in particular, has been couched in the broadest of terms. Beginning in the 1990s, this application was expressed in terms …

Comparison Of Piping Plover Foraging Habitat On Artificial And Natural Sandbars On The Missouri River, Daniel H. Catlin, Joy H. Felio, James D. Fraser

The Prairie Naturalist

The presence of food close to nesting habitat is essential for piping plover (Charadrius melodus) reproductive output. Since 2004, the U.S. Army Corps of Engineers has been engineering artificial nesting and brood-rearing habitat for piping plovers on the Missouri River. We compared arthropod abundance indices from artificial and natural sandbars as part of an evaluation of foraging habitat. The artificial sandbars had fewer and different arthropods than natural sandbars. The arthropod indices, however, need to be considered in light of total area of foraging habitat. Although there were fewer arthropods on artificial sandbars, the abundance of foraging habitat and relatively …

Evidence Of American Martens Populating The Turtle Mountains Of North Dakota, Amber J. Bagherian, Dorothy M. Fecske, Maggie D. Triska, Joseph A. Bishop, Dean J. Berezanski, Sandra K. Johnson, Robert P. Brooks, Thomas L. Serfass

The Prairie Naturalist

American martens (Martes americana) were native to northeastern North Dakota but were considered extirpated by the early 1800s. Although there is no historic evidence of martens occurring beyond the northeast, forested habitat potentially suitable for martens exists in the Turtle Mountains region of northcentral North Dakota and southwestern Manitoba. From 1989– 1991, the Turtle Mountain Trappers Association translocated 59 martens into the Canadian portion of the Turtle Mountains. During summer 2007, we used covered track-plates and/or remotely-triggered cameras placed at 123 survey sites distributed among 41 1-km2 grid cells (a GIS-generated layer imposed on electronic maps of the study region) …

Topographic Home Range Of Large Mammals: Is Planimetric Home Range Still A Viable Method?, W. David Walter, Justin W. Fischer, Teresa J. Frink, Scott E. Hygnstrom, Jonathan A. Jenks, Kurt C. Vercauteren

The Prairie Naturalist

Topography influences movement trajectories, quality of forages used, and behavioral response of large herbivores to anthropogenic disturbances, but research is lacking on the influence of terrain complexity on size of home range. Size of home range usually is based on planimetric area and therefore rarely accounts for the true surface area traversed by an animal. We conducted radiotelemetry on bighorn sheep (Ovis canadensis), Rocky Mountain elk (Cervus elaphus), mule deer (Odocoileus hemionus), and white-tailed deer (O. virginianus) equipped with VHF collars at three sites from 2002 to 2006 to document size of home range in areas that ranged from 400 …

Chlorophyll-Based Approach For Remote Estimation Of Crop Gross Primary Production: From In Situ Measurements To Satellite Imagery, Yi Peng

School of Natural Resources: Dissertations, Theses, and Student Research

The synoptic and accurate quantification of crop gross primary production (GPP) is essential for studying carbon budgets in croplands and monitoring crop status. The objective of this dissertation is to develop a quantitative technique to estimate crop GPP using remotely sensed data collected from close range to satellite altitudes. In this study, a model based on a recently developed paradigm, which relates crop GPP to a product of total crop chlorophyll content and incident radiation affecting vegetation photosynthesis, was justified for the remote estimation of GPP in crops. The model was tested with ground-observed incoming photosynthetically active radiation (PAR_{in …}

Notes: Red-Tailed Hawk Predation Of A Striped Skunk, Steven G. Platt, Thomas R. Rainwater

The Prairie Naturalist

Skunks (Mephitidae) are capable of projecting pungent, oily musk from paired anal glands (Verts 1967), which acts as a central nervous system depressant (Wade- Smith and Verts 1982), and can incapacitate birds of prey if directed into the eyes (Garcelon 1981). Consequently, few raptors are known to prey on striped skunks (Mephitis mephitis). Great horned owls (Bubo virginianus) are the only raptor that regularly preys on skunks (Bent 1938b, Lowery 1974, Houston et al. 1998), although occasional instances of predation by golden eagles (Aquila chrysaetos; Olendorff 1976, Palmer 1988a), bald eagles (Haliaeetus leucocephalis; Broley 1952, Wade-Smith and Verts 1982), northern …

Least And Merriam’S Shrews From Banner County, Nebraska, Jennifer N. Merlino, Alexandra R. Frohberg, Jamie Harmon, Keith Geluso

The Prairie Naturalist

Four species of shrews occur in the panhandle of western Nebraska – the masked shrew (Sorex cinereus), Merriam’s shrew (S. merriami), dwarf shrew (S. nanus), and least shrew (Cryptotis parva; Genoways et al. 2008). Little information is known regarding the distribution and habitat of those species due to few captures of individuals throughout the region (e.g., Jones 1964, Freeman et al. 1993, Benedict et al. 1999, 2000, Geluso et al. 2004). To date, no shrew has been reported from the southwestern part of the panhandle in Banner, Kimball, or Cheyenne counties. Here we present distributional records for the least shrew …

Grass And Canada Goldenrod (Solidago Canadensis) Competition And Implications For Management In The Northern Tallgrass Prairie, Alexander J. Smart, Gary E. Larson, Peter J. Bauman

The Prairie Naturalist

Canada goldenrod (Solidago canadensis L.) is a native perennial forb that can form dense clonal patches and become weedy in pastures of the Northern Tallgrass Prairie Ecoregion. Our objectives were to determine 1) the competitive effects between Canada goldenrod and grass, 2) the relationship between Canada goldenrod stem density and grass biomass, and 3) the distribution of Canada goldenrod stem density at the pasture scale. We used regression analysis to develop a relationship between Canada goldenrod stem density and grass biomass. Additionally, we estimated the frequency distribution of Canada goldenrod stem density categories using three evenly distributed 100 × 100-m …

Spatiotemporal Variation In Vegetation Structure Resulting From Pyric-Herbivory, Sherry Leis, Lloyd W. Morrison, Michael D. Debacker

The Prairie Naturalist

Pyric-herbivory is a process that is widely assumed to create greater habitat heterogeneity in grasslands at the landscape scale than could be achieved by either fire or grazing alone. Yet, few studies have actually quantified the effects of pyric- herbivory on vegetation structure within layers of the grass canopy. Here we quantify the effects of pyric-herbivory on a pasture at Tallgrass Prairie National Preserve in Kansas. We subdivided the pasture into three patches and burned one patch each year in a three-year rotation. We estimated visual obstruction for 25-cm strata and recorded maximum vegetation height. We found that recently burned …

Sickleweed On The Fort Pierre National Grassland: An Emerging Threat, Jack L. Bulter, Stefanie D. Wacker

The Prairie Naturalist

We report the first detailed field survey of sickleweed (Falcaria vulgaris L.) in the United States. Sickleweed is native to Europe, the Mediterranean, Asia Minor, and Iran and was first reported in the United States in 1922. It is listed by the Nebraska Invasive Species Council as a Category II invasive plant species. In recent years, abundance and distribution of sickle- weed has increased dramatically in and around the Fort Pierre National Grassland (FPNG), South Dakota. Management of such a rapidly expanding population is hampered by a general lack of baseline information on the biology and ecology of sickleweed. We …

Spatial Ecology Of Urban Raccoons In Northeastern Ohio: Implications For Oral Rabies Vaccination, Are R. Berentsen, Mike R. Dunbar, Chadd E. Fitzpatrick, W. David Walter

The Prairie Naturalist

In 1977, rabies was detected in a raccoon (Procyon lotor) in West Virginia, and since the mid-1980s raccoon variant rabies has spread throughout the eastern United States and moved west as far as the eastern edge of Cleveland, Ohio. The primary tool to combat this spread is the distribution of oral rabies vaccine (ORV) baits. A thorough knowledge of raccoon space use is critical in determining bait placement, particularly in urban areas. We monitored nine raccoons in urban areas of Cleveland, Ohio, calculated home range sizes, monitored raccoon movement with respect to potential movement barriers, and used resource selection functions …

Territories,Territoriality, And Conservation Of The Louisiana Waterthrush And Its Habitat, The Watershed Of The Upper Buffalo National River, Leesia Cheryl Marshall

Graduate Theses and Dissertations

The Louisiana Waterthrush, Parkesia motacilla, is a migratory wood-warbler and breeding season resident of the eastern United States. Males defend breeding territories that extend linearly along clear, fast-flowing, gravel-bottomed, forest streams. Defense includes two song types, primary and extended song. As riverine specialists, birds rely upon aquatic invertebrates as prey and riparian habitat features for nesting. They use a unique foraging maneuver, leaf-pulling, that involves picking up or pulling a leaf from water, and turning it over to search for prey. Their relationship with riparian habitat introduces potential for Louisiana Waterthrushes to serve as indicators of stream health. The …

An Evaluation Of Stocking And Habitat Influences On Channel Catfish In Lentic Ecosystems Of The Great Plains, Lindsey K. Chizinski

School of Natural Resources: Dissertations, Theses, and Student Research

Channel catfish Ictalurus punctatus is an important sport fish, particularly in the Great Plains. In Nebraska, a majority of anglers target channel catfish, and fishing activities are a vital part of the state’s economy. Lentic water bodies provide the primary fishing opportunity for catfish anglers in Nebraska. Despite the popularity and economic importance of channel catfish, little is known of its population dynamics or habitat requirements, and existing studies often profile river populations. Current standards for sampling channel catfish in lentic systems often yield inadequate catch to assess populations. The objective of this study was to utilize a recently developed …

Natural And Constructed Wetlands For Ecosystem And Engineering Services In The Arid And Semi-Arid Regions, Achyut Raj Adhikari

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas Wash (LVW) has undergone significant wetlands degradation and soil erosion over the past thirty years due to increasing flow resulting from urbanization and large rainfall events in the Las Vegas Valley Watershed. The increased flow and associated pollution load in the LVW and its adverse impact in Lake Mead have alerted stakeholders to pay a greater attention to explore alternative measures for rehabilitation of wetland ecosystems. This dissertation, using the case of changes in LVW, analyzes and describes ecological and engineering services provided by wetlands in arid and semi-arid regions and provides a knowledge base that can …

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea

Independent Study Project (ISP) Collection

Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …

The Kennebec River: A Historic Maine Resource, Elise Begin

Historical Ecology Atlas of New England

The Kennebec River has been considered one of Maine’s most important resources for at least the past 6-8 thousand years; its basin is located in west central Maine and drains 5,893 square miles, an area that is approximately one-fifth the area of the state. The river originates at Moosehead lake and runs 170 miles to the Atlantic Ocean. The river can be divided into two basins: the upper basin, which spans from Moosehead Lake to Waterville; and the lower basin, which spans from Waterville to the ocean.

Before the arrival of Europeans in 1606, the Abenaki Indians controlled the entirety …

The Happy Valley, Cassie Raker

Historical Ecology Atlas of New England

On the Connecticut River in Western Massachusetts, there exists the Happy Valley. Surrounded by the humble Holyoke Range, today you will find a bustling New England settlement dominated by local colleges and universities. But it was not always so. The picturesque Mount Holyoke and its accompanying hotel, known as the Summit House, have overlooked the area for hundreds of years, watching it change from forest to farmland to industry to the modern landscape it is today.
