Obituary: Jerry Ronald Choate, 1943-2009, Elmer J. Finck, Hugh H. Genoways, Justin D. Hoffman, Carleton J. Phillips, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
Jerry Ronald Choate (1943–2009) had just retired as Director of the Sternberg Museum of Natural History and Professor of Biological Sciences, Fort Hays State University, Hays, Kansas, at the time of his death. Jerry served the American Society of Mammalogists in numerous capacities, including Recording Secretary, First Vice President, and most notably as a member and chair of the Board of Trustees.
The hallmark of Jerry’s life was to turn the ordinary into something magnificent. Whether it was his photography that changed an ordinary landscape into a magnificent masterpiece, or his convincing a reluctant graduate student that they could do …
A Comparison Of The Clarendonian Equid Assemblages From The Mission Pit, South Dakota And Ashfall Fossil Beds, Nebraska, Nicholas A. Famoso, Darrin Pagnac
A Comparison Of The Clarendonian Equid Assemblages From The Mission Pit, South Dakota And Ashfall Fossil Beds, Nebraska, Nicholas A. Famoso, Darrin Pagnac
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Mission Pit locality (SDSM V5314), near Mission, South Dakota, has produced a large collection of equid teeth obtained from the Miocene Ash Hollow (=Thin Elk) Formation. Ashfall Fossil Beds (UNSM Ap-116), near Royal, Nebraska, has yielded an extensive collection of equid cranial elements and teeth derived from the Cap Rock Member, Ash Hollow Formation. The two sites are interpreted to be Clarendonian in age [12.5 to 9.0 Ma], but may contain faunal assemblages from differing Clarendonian subages.
The two sites exhibit a notably similar composition of equid genera, including the tribes Equini (Pliohippus, Calippus, and Protohippus …

Group Size And Nest Spacing Affect Buggy Creek Virus (Togaviridae: Alphavirus) Infection In Nestling House Sparrows, Valerie A. Brown, Charles R. Brown
Group Size And Nest Spacing Affect Buggy Creek Virus (Togaviridae: Alphavirus) Infection In Nestling House Sparrows, Valerie A. Brown, Charles R. Brown
Papers in Ornithology
The transmission of parasites and pathogens among vertebrates often depends on host population size, host species diversity, and the extent of crowding among potential hosts, but little is known about how these variables apply to most vector-borne pathogens such as the arboviruses (arthropod-borne viruses). Buggy Creek virus (BCRV; Togaviridae: Alphavirus) is an RNA arbovirus transmitted by the swallow bug (Oeciacus vicarius) to the cliff swallow (Petrochelidon pyrrhonota) and the introduced house sparrow (Passer domesticus) that has recently invaded swallow nesting colonies. The virus has little impact on cliff swallows, but house sparrows are seriously …

Rapidly expanding growth in the field of nanotechnology has led to the development of numerous applications of nanomaterials in industrial (e.g., paints, electronics) and consumer (e.g., cosmetics, clothing treatments) products. These engineered nanoparticle (NP)-containing products have, however, the potential to release particles (single or aggregates) or ions by means of wastewater discharge into the aquatic environment. SCENIHR (2006) emphasized that the behavior of NPs is critically dependent on several particle characteristics, including size, surface area and surface reactivity, and that risk assessments for both human health and the environment have to be based on these characteristics. However, in practice, risks …

Blarina Hylophaga (Sorciomorpha: Soricidae), Cody W. Thompson, Jerry R. Choate, Hugh H. Genoways, Elmer J. Finck
University of Nebraska State Museum: Mammalogy Papers
Blarina hylophaga (Elliot, 1899) is a soricid commonly called Elliot’s short-tailed shrew. A short-legged, robust shrew with a long, pointed snout and a short tail; it is 1 of 4 species in the genus Blarina. It occurs throughout most of the Great Plains of the United States, where it inhabits moist, well-drained grassland and riparian areas with deep leaf litter. It is listed as a species of greatest conservation need in Iowa and at possible risk in Texas, which might be due to the limited knowledge of the species throughout its geographic range.

School of Natural Resources: Faculty Publications
Many of the arthropod-borne viruses (arboviruses) show extensive genetic variability and are widely distributed over large geographic areas. Understanding how virus genetic structure varies in space may yield insight into how these pathogens are adapted to and dispersed by different hosts or vectors, the relative importance of mutation, drift, or selection in generating genetic variability, and where and when epidemics or epizootics are most likely to occur. However, because most arboviruses tend to be sampled opportunistically and often cannot be isolated in large numbers at a given locale, surprisingly little is known about their spatial genetic structure on the local …

Genetic Variation And Inheritance Of Diapause Induction In Two Distinct Voltine Ecotypes Of Ostrinia Nubilalis (Lepidoptera: Crambidae), Cengis Ikten, Steven R. Skoda, Thomas E. Hunt, Jaime Molina-Ochoa, John E. Foster
Genetic Variation And Inheritance Of Diapause Induction In Two Distinct Voltine Ecotypes Of Ostrinia Nubilalis (Lepidoptera: Crambidae), Cengis Ikten, Steven R. Skoda, Thomas E. Hunt, Jaime Molina-Ochoa, John E. Foster
Department of Entomology: Faculty Publications
European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), displays a larval diapause in response to short photoperiods and is adapted to a variety of local conditions throughout North America. Hence, the effective photoperiod inducing larval diapause will differ among geographic ecotypes. This study considers the inheritance of photoperiodic larval diapause induction by hybridization and backcrossing two latitudinally distinct ecotypes of the European corn borer collected between 41° N, 96° W and 48° N, 96° W and under a range of photoperiods representative of their respective locations: from 14:10 to 16:8 (L:D) h. The ecotype adapted to a bivoltine habitat (southeastern …

Systematic Revision Of The Northern Short-Tailed Shrew, Blarina Brevicauda (Say), Wm. David Webster, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Short-tailed shrews, genus Blarina, are common inhabitants of a variety of terrestrial habitats in most of eastern North America. Of the 4 species currently recognized, the northern short-tailed shrew, Blarina brevicauda (Say, 1823), is the most widely distributed, occurring from southern Canada southward to the central Great Plains and the Appalachian Mountains into Georgia and Alabama and along the East Coast as far south as southeastern North Carolina. It has been more than 65 years since geographic variation within this species has been studied. Accordingly, the objectives of this study were to examine geographic variation in Blarina brevicauda and …
Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg
Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg
USGS Northern Prairie Wildlife Research Center
Minnesota wolves (Canis sp.) sometimes are reported to have affinity to a small, narrow-skulled eastern form (Canis lupus lycaon Schreber, 1775) and sometimes to a larger, broader western form (Canis lupus nubilus Say, 1823). We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970–1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and …

Long-Term Clinicopathological Characteristics Of Alpacas Naturally Infected With Bovine Viral Diarrhea Virus Type Ib, D. Bedenice, Edward J. Dubovi, Clayton Kelling, Jamie N Henningson, Christina L. Topliff, N. Parry
School of Veterinary and Biomedical Sciences: Faculty Publications
Background: Substantial bovine viral diarrhea virus (BVDV)-related production losses in North American alpaca herds have been associated with BVDV type Ib infection.
Objectives: To classify and differentiate the long-term clinicopathological characteristics of BVDV type Ib infection of al- paca crias, after natural virus exposure. We hypothesized that persistently infected (PI) alpacas specifically demonstrate growth retardation, clinicopathological evidence of opportunistic infections, and early mortality.
Animals: Thirty-five crias naturally exposed to BVDV (18 acute, 3 chronic, 14 PIs), and 19 healthy cohort controls of 5 northeastern alpaca farms were prospectively evaluated over 2 years (September 2005–September 2008).
Methods: Observational cohort-control study.
Results: …

The ability of Spalangia cameroni Perkins, Spalangia endius Walker, and Muscidifurax raptorellus Kogan and Legner to locate and attack stable fly hosts was evaluated under laboratory conditions. Postfeeding third-instar stable fly larvae were released and allowed to pupate in two arena types: large 4.8 liter chambers containing a field-collected, soiled equine bedding substrate; or 120-ml plastic cups containing wood chips. At the time of fly pupariation, parasitoids were released and permitted 72 h to locate and attack hosts. On average, parasitism rates of freely accessible stable fly pupae in cups were not significantly different between parasitoid species. However, parasitism rates …

A broad understanding of multimodal courtship function necessitates knowledge of the potential information content of signal components, the efficacy of signal components in eliciting the appropriate receiver response, and the fitness consequences of mating decisions based upon various signal components. We present data addressing each of these requirements for the multimodal-signaling wolf spider, Schizocosa floridana Bryant. Using diet manipulations, we first demonstrate that both visual and seismic courtship signals are condition-dependent. Next, using high- and low-quantity diet individuals in mate choice trials across manipulated signaling environments, we demonstrate that the seismic signal is crucial for mating success and further show …

Body Mass Index Is Associated With Dietary Patterns And Health Conditions In Georgia Centenarians, Dorothy B. Hausman, Mary Ann Johnson, Adam Davey, Leonard W. Poon
Department of Nutrition and Health Sciences: Faculty Publications
Associations between body mass index (BMI) and dietary patterns and health conditions were explored in a population-based multiethnic sample of centenarians from northern Georgia. BMI ≤20 and ≥25 was prevalent in 30.9% and 25.3% of study participants, respectively. In a series of logistic regression analyses controlled for gender and place of residence, the probability of having BMI ≥25 was increased by being black versus white and having a low citrus fruit, noncitrus fruit, orange/yellow vegetable or total fruit and vegetable intake. The probability of having BMI ≤20 was not associated with dietary intake. When controlled for race, gender, residence, and …
Where Have All The Plant Foods Gone? The Search For Refined Dietary Reconstruction From Chinchorro Mummies, Karl J. Reinhard, Sara Le-Roy-Toren, Bernardo Arriaza
Where Have All The Plant Foods Gone? The Search For Refined Dietary Reconstruction From Chinchorro Mummies, Karl J. Reinhard, Sara Le-Roy-Toren, Bernardo Arriaza
Karl Reinhard Publications
The Chinchorro cemeteries of northern Chile are the first graveyards of the Andes (Arriaza 1995, Schiappacasse & Niemeyer 1984). The excavation and analysis of Chinchorro mummies reveals the 'true character of the people'. The burials themselves are optimal for preservation of corpses, burial furniture, and aspects of ceremonies associated with the dead. The analysis of corporeal remains gradually clarifies the details of daily activities and status. Therefore, we feel that a holistic approach to mummy studies provides enormously fruitful paths to understanding the character of the ancient Chinchorro society.
