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 …

During my tenure as Editor-in-Chief (Editor), I have had the good fortune of working with many authors and a truly dedicated Editorial Staff. Most topics for editorials come to me relatively easily, though admittedly I found myself scratching my head when thinking about a topic for this editorial. After much pensive thought, …

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 …

Unlv Students To Build Zero Net Energy Home; Boom & Bust Report, Nevada Institute For Renewable Energy Commercialization (Nirec)

Nevada Newsflash

Design and build an approximately 800 square foot home that consumes zero net energy.

Those are the instructions for Team Las Vegas, after the University of Nevada, Las Vegas (UNLV) became one of only 20 schools worldwide to quality for the 2013 Solar Decathlon, sponsored by the U.S. Department of Energy’s National Renewable Energy Laboratory.

UNLV’s entry, Autonomy House, is marketed as an “age-in-place” home for an empty nester whose children have grown up. The 730-squarefoot home will use daylighting from windows, insulation and solar panels to produce more energy than it consumes. Additionally, it will filter rainwater for household …

Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh

Pomona Senior Theses

This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.

Improving Woody Biomass Estimation Efficiency Using Double Sampling, David L. Parrott, John M. Lhotka, Songlin Fei, B. Scott Shouse

Forestry and Natural Resources Faculty Publications

Although double sampling has been shown to be an effective method to estimate timber volume in forest inventories, only a limited body of research has tested the effectiveness of double sampling on forest biomass estimation. From forest biomass inventories collected over 9,683 ha using systematic point sampling, we examined how a double sampling scheme would have affected precision and efficiency in these biomass inventories. Our results indicated that double sample methods would have yielded biomass estimations with similar precision as systematic point sampling when the small sample was ≥ 20% of the large sample. When the small to large sample …

Near Infrared-Red Models For The Remote Estimation Of Chlorophyll-Α Concentration In Optically Complex Turbid Productive Waters: From In Situ Measurements To Aerial Imagery, Daniela Gurlin

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

Today the water quality of many inland and coastal waters is compromised by cultural eutrophication in consequence of increased human agricultural and industrial activities and remote sensing is widely applied to monitor the trophic state of these waters. This study explores near infrared-red models for the remote estimation of chlorophyll-a concentration in turbid productive waters and compares several near infrared-red models developed within the last 35 years.

Three of these near infrared-red models were calibrated for a dataset with chlorophyll-a concentrations from 2.3 to 81.2 mg m^-3 and validated for independent and statistically significantly different datasets with …

Roger Williams Park Edible Forest Garden, Mark S. Scialla

Senior Honors Projects

An edible forest garden is a low-maintenance system that uses edible native and regionally-adapted plants arranged in beneficial relationships to meet human, wildlife and ecosystem needs. The forest garden in Roger Williams Park will transform underutilized urban land into a highly productive parcel producing market-viable fruits, nuts, vegetables, medicine and fiber. Forest gardens mimic natural forest systems in architecture and complexity. The design follows ecological principles to create a system that promotes biodiversity and enhances the surrounding ecosystem. This project also demonstrates the potential to grow food and create land-based livelihoods in the city.

Located on the edge of a …

Remote Estimation Of Crop Gross Primary Production With Landsat Data, Anatoly Gitelson, Yi Peng, Jeffrey G. Masek, Donald Rundquist, Shashi Verma, Andrew E. Suyker, John M. Baker, Tilden Meyers

School of Natural Resources: Faculty Publications

An accurate and synoptic quantification of gross primary production (GPP) in crops is essential for studies of carbon budgets at regional and global scales. In this study, we tested a model, relating crop GPP to a product of total canopy chlorophyll (Chl) content and potential incident photosynthetically active radiation (PAR_potential). The approach is based on remotely sensed data; specifically, vegetation indices (VI) that are proxies for total Chl content and PARpotential, which is incident PAR under a condition of minimal atmospheric aerosol loading. Using VI retrieved from surface reflectance Landsat data, we found that the model is capable …
