Records Of The Red-Bellied Snake (Storeria Occipitomaculata) In Central And Northeastern Nebraska, Taylor Lowe, Sarah M. Bailey, Dan D. Fogell, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Red-bellied Snakes (Storeria occipitomaculata) are a distinctive, small species that live in moist woodlands throughout much of eastern North America. In the Great Plains, isolated populations exist in South Dakota, Wyoming, and Nebraska. In Nebraska, the only known extant population occurs in wooded riparian habitats along the Big Bend Reach of the Platte River in southcentral parts of the state. Herein, we report on new county records of Red-bellied Snakes in Nebraska, with two observations from Merrick County along the Platte River adjacent to known populations and two observations of a new population in the extreme northeastern part …
The Effect Of An Oak Savanna Habitat Restoration On Bat Activity In Eastern Nebraska, Aidan Hatfield, Jeremy White
The Effect Of An Oak Savanna Habitat Restoration On Bat Activity In Eastern Nebraska, Aidan Hatfield, Jeremy White
Theses/Capstones/Creative Projects
Oak savanna habitat has been drastically reduced throughout the Midwest. Temperate bats generally are edge adapted and may better utilize a restored oak savanna habitat than the now common deciduous forests that replaced them. Therefore, we analyzed the activity of 7 bats native to eastern Nebraska and in the process, compared the agreement of two different programs that claim to automatically identify bat species. In order to investigate this, we placed three audio detectors within both habitats for 1 week and allowed them to record from sunset to sunrise. The data obtained was analyzed and compared between two programs, Kaleidoscope …
Pronghorn Survival And Resource Selection In Western Nebraska's Agriculturally Dominated Landscape, Katie Piecora
Pronghorn Survival And Resource Selection In Western Nebraska's Agriculturally Dominated Landscape, Katie Piecora
School of Natural Resources: Dissertations, Theses, and Student Research
Nebraska’s pronghorn population has been stable over the last decade, yet their presence on the landscape remains a contentious subject amongst private landowners. Conversion of grassland for crop production and increased anthropogenic activity has drastically altered pronghorn behavior throughout their current range, however basic ecology and resource use by pronghorn in Nebraska remains poorly understood. Establishing baseline population metrics and seasonal patterns of resource use for this population at the eastern periphery of the species range is critical to guide management actions. We deployed GPS collars on 110 adult pronghorn to quantify survival, mortality risk, and seasonal resource selection in …
Use Of Soapweed Yucca (Yucca Glauca) By Rodents And Other Vertebrates In Western Nebraska, Michael L. Rohde, Keith Geluso, Carter Kruse, Mary J. Harner
Use Of Soapweed Yucca (Yucca Glauca) By Rodents And Other Vertebrates In Western Nebraska, Michael L. Rohde, Keith Geluso, Carter Kruse, Mary J. Harner
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Soapweed Yucca (Yucca glauca) is a conspicuous and common shrub in the Great Plains of North America, characterized by tall woody flower stalks, large flowers and seed pods, and dense masses of ground-level evergreen leaves. These plant structures can provide a variety of resources or functions to animals. In general, studies focus on single species associated with Y. glauca. We examined three groups of vertebrates that interacted with Y. glauca and the functions this plant provided for organisms in western Nebraska. We experimentally examined small mammals in areas with and without Y. glauca, and we descriptively …
Constraining Neogene Temperature And Precipitation Histories In The Central Great Plains Using The Fossil Record Of Alligator, Evan Whiting
Constraining Neogene Temperature And Precipitation Histories In The Central Great Plains Using The Fossil Record Of Alligator, Evan Whiting
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Most amphibians and reptiles (excluding birds) are poikilothermic; their internal body temperature varies with that of their external environment. This makes them useful as climate proxies, especially when linked to geographic distributions of ambient climate. I evaluate the utility of the extant crocodylian genus Alligator as a paleoclimate proxy for the Central Great Plains (CGP) using species distribution modeling. Alligator is a readily identifiable taxon with a good CGP fossil record during the Neogene (~23–2.6 Ma). Alligator first appeared in the CGP in the late Eocene (~37 Ma), was absent during most of the Oligocene, reappeared in the early Miocene …
Assessment Of Disturbance Effects Of An Existing Wind Energy Facility On Greater Prairie-Chicken (Tympanuchus Cupido Pinnatus) Breeding Season Ecology In The Sandhills Of Nebraska, Jocelyn O. Harrison
Assessment Of Disturbance Effects Of An Existing Wind Energy Facility On Greater Prairie-Chicken (Tympanuchus Cupido Pinnatus) Breeding Season Ecology In The Sandhills Of Nebraska, Jocelyn O. Harrison
School of Natural Resources: Dissertations, Theses, and Student Research
Recent wind energy development in the Great Plains of North America has given rise to concerns of potential impacts on the greater prairie-chicken (Tympanuchus cupido pinnatus). Recent studies in fragmented landscapes have suggested greater prairie-chickens may avoid wind facilities, which may lead to habitat loss and negative impacts on reproduction and survival. But, it is unknown if there is a similar effect in contiguous grass landscapes. Thus, we investigated the effect of a pre-existing, 36-turbine wind energy facility on greater prairie-chicken nesting, brood-rearing, and spatial ecology in the Nebraska Sandhills. We captured and marked 78 female greater prairie-chickens …

Winter Activity Of Bats In Southeastern Nebraska: An Acoustic Study, Jeremy A. White, Brett R. Andersen, Hans W. Otto, Cliff A. Lemen, Patricia W. Freeman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Many North American bats are active outside hibernacula in winter, but no information on winter activity has been reported for Nebraska. We recorded activity of bats during two winters (December-February 2012-2013 and 2013-2014) at one location in southeastern Nebraska with an acoustic detector. Bats were active throughout both winters and temperature at sunset was a good predictor of bat activity. Red bats (Lasiurus borealis) were active at our site in early December but were not recorded later in winter. We suspect these individuals were late migrants to more southern wintering sites. Big brown bats (Eptesicus fuscus) …

Helminth Parasites Of The Raccoon (Procyon Lotor), Virginia Opossum (Didelphis Virginiana), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Dennis J. Richardson
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Nine raccoons (Procyon lotor), 6 Virginia opossums (Didelphis virginiana), and 1 striped skunk (Mephitis mephitis) collected from Keith County, Nebraska were examined for helminth parasites. Raccoons were infected with the nematodes Arthrocephalus lotoris, Baylisascaris procyonis, and Capillaria plica, the trematode Fibricola cratera, and the tapeworm Atriotaenia procyonis. Opossums were infected with 1 nematode, 1 trematode, and 1 cestode species: Physaloptera turgida, Plagiorhchis elegans, and Oochoristica sp., respectively. The single striped skunk was infected with the nematode Physaloptera maxillaris and the cestodes Mesocestoides sp. and Oochoristica sp.
Ectoparasites Of The Virginia Opossum (Didelphis Virginiana), Raccoon (Procyon Lotor), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Lance A. Durden, Dennis J. Richardson
Ectoparasites Of The Virginia Opossum (Didelphis Virginiana), Raccoon (Procyon Lotor), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Lance A. Durden, Dennis J. Richardson
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Six Virginia opossums (Didelphis virginiana), nine raccoons (Procyon lotor) and one striped skunk (Mephitis mephitis) collected from Keith County Nebraska were examined for ectoparasites. All three host species were parasitized by adults of the American dog tick, Dermacentor variabilis. Opossums were also parasitized by the flea Pulex simulans and the tiny fur mite Didelphilichus serrifer; the latter species represents a new state record for Nebraska. Raccoons were also parasitized by P. simulans and by the lagomorph-associated flea Euhoplopsyllus glacialis affinis, whereas the skunk was also parasitized by the chewing louse Neotrichodectes …
Reexamination Of Herpetofauna On Mormon Island, Hall County, Nebraska, With Notes On Natural History, Keith Geluso, Mary J. Harner
Reexamination Of Herpetofauna On Mormon Island, Hall County, Nebraska, With Notes On Natural History, Keith Geluso, Mary J. Harner
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Platte River in central Nebraska, USA, was historically surrounded by mixed grass and tallgrass prairies and wet meadows, but many of those habitats were lost or altered during the last century with unknown effects on animals that reside in them. Researchers first surveyed herpetofauna on part of a large island preserve in the Platte River, Mormon Island, Hall County, Nebraska, in 1980 when the land was protected for conservation. They documented 10 species, including three species of amphibians and seven species of reptiles. We inventoried herpetofauna after 30 years of conservation management on Mormon Island and adjacent Shoemaker Island. …
Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley
Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley
School of Natural Resources: Dissertations, Theses, and Student Research
The Central Platte River Valley (CPRV) in Nebraska is an important spring stopover area for the midcontinent population of sandhill cranes. Alterations to crop rotation and loss habitat in the CPRV pose a risk to the population. Personnel drove designated routes in the CPRV from 2003–2010 to record the presence of cranes in agricultural fields and estimate abundance. I developed and evaluated models to predict habitat use and flock sizes. Alfalfa was predicted to receive the highest use followed by corn, soybeans, winter wheat, grassland, and shrubland. Use of all habitats and flock size increased as field area increased. Flock …
Eumeces Septentrionalis (Prairie Skink): Piscivory., Louis A. Somma
Eumeces Septentrionalis (Prairie Skink): Piscivory., Louis A. Somma
Papers in Herpetology
The prairie skink is a North American lizard characterized by a diet that is primarily insectivorous (Breckenridge 1943. Amer. MidI. Nat. 29:591-606). Fish have not been previously recorded as a food item (reviewed in Somma and Cochran 1989. Great Basin Nat. 49:525-534). On 3 June 1990 between 0930 and 1030 h, six Eumeces septentrionalis (three gravid females, one male, and two juveniles) were captured from amongst riprap and beneath stone slabs on the earthen dam forming the windward shoreline of Burchard lake, Pawnee Co., Nebraska (T.12N., R.10E., Sec. 4). The three females and one juvenile were placed in the …
Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud
Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …
