Wild Primate Populations In Emerging Infectious Disease Research: The Missing Link?, Nathan D. Wolfe, Ananias A. Escalante, William B. Karesh, Annelisa Kilbourn, Andrew Spielman, Altaf A. Lal
Harold W. Manter Laboratory of Parasitology: Library Materials
Wild primate populations, an unexplored source of information regarding emerging infectious disease, may hold valuable clues to the origins and evolution of some important pathogens. Primates can act as reservoirs for human pathogens. As members of biologically diverse habitats, they serve as sentinels for surveillance of emerging pathogens and provide models for basic research on natural transmission dynamics. Since emerging infectious diseases also pose serious threats to endangered and threatened primate species, studies of these diseases in primate populations can benefit conservation efforts and may provide the missing link between laboratory studies and the well-recognized needs of early disease detection, …
Major Histocompatibility Complex Class I- And Ii-Deficient Knock-Out Mice Are Resistant To Primary But Susceptible To Secondary Eimeria Papillata Infections, Marco L. Schito, Bill Chobotar, John R. Barta
Major Histocompatibility Complex Class I- And Ii-Deficient Knock-Out Mice Are Resistant To Primary But Susceptible To Secondary Eimeria Papillata Infections, Marco L. Schito, Bill Chobotar, John R. Barta
Faculty Publications
Two distinct mechanisms seem to function in reducing oocyst output during Eimeria papillata infections in mice. For naive mice, immunity was afforded by a T-cell-independent gamma-interferon (IFN-γ) response mediated by natural killer (NK) cells. On reinfection, resistance was associated with T-cells and, to a lesser extent, perforin. To determine if antigen presentation with major histocompatibility complex (MHC) molecules was required to control oocyst production by NK cells during primary infection or by T-cells during secondary infection, mutant mice that lacked H2-IAβb (Aβb(-/-)) or β2-microglobulin (β2m(-/-)) were used. Since MHC molecules are required for the maturation of αβ T-cells, Aβb(-/-) and …
Two New Subspecies Of Bats Of The Genus Sturnira, Hugh H. Genoways
Two New Subspecies Of Bats Of The Genus Sturnira, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
The last systematic review of the yellow-shouldered bats of the Neotropical genus Sturnira in the Lesser Antilles was in 1976 (Jones and Phillips, 1976). At that point in time, two species--Sturnira lilium and Sturnira thomasi--were known from these islands. Sturnira lilium was represented by five subspecies, beginning with Trinidad and moving northward, these subspecies were lilium on Trinidad (Goodwin and Greenhall, 1961), paulsoni on St. Vincent (de Ia Torre and Schwartz, 19661, luciae on St. Lucia (Jones and Phillip, 19761, zygomaticus on Martinique (Jones and Phillips, 1976), and angeli on Dominica (de la Tom, 1966).

Nebraska Bird Review
During a birding trip on 19 July 1997, we stopped at Funk WPA, Phelps County. While viewing from the north-south road that runs through the marsh at the east end of the marsh, we caught glimpses of a large group of shorebirds behind cattails in an area on the south side of the main marsh and about a third of a mile west of the road. We eventually decided to walk out and get a closer look at the shorebirds. Once we were close enough we were able to see that there were approximately 250 shorebirds. We began sifting through …

Bald Eagle Nest Monitoring - Nebraska, 1997 Summary Report, John J. Dinan
Bald Eagle Nest Monitoring - Nebraska, 1997 Summary Report, John J. Dinan
Nebraska Bird Review
In 1997, 38 Bald Eagle (Haliaeetus leucocephalus) nests in 22 counties were surveyed for breeding activity. Eagles occupied territories at 10 of these sites. These same 10 territories were occupied in 1996. Two separate, mid-July sightings of Bald Eagles along the Niobrara River, one of an adult and three juveniles in Knox County and one of an adult and a juvenile in Holt County, suggests the presence of additional nesting territories. All nest attempts in 1997 were successful, producing a total of 16 fledged young. The Lake Alice nest on the North Platte National Wildlife Refuge fell during …

Winter Field Report, Dec 1997 To Feb 1998, W. Ross Silcock, Joel G. Jorgensen
Nebraska Bird Review
As one observer (DH) noted, this was a "weird" winter. January and February were more like March, producing winter reports of species with few such previous reports; the species involved come from all parts of the taxonomic list, from loons to icterids. Almost certainly, a first (in recorded history) was a slam of all the Nebraska grebe species in January, even Red-necked and Clark's! Also in January, a Pacific Loon was reported. As shown in the species' accounts below, the list of rare midwinter species is long.
Another significant, related finding involved early-arriving spring migrants, also a long list. In …
Mystery Duck At Sinninger Waterfowl Production Area, York County, Joel G. Jorgensen
Mystery Duck At Sinninger Waterfowl Production Area, York County, Joel G. Jorgensen
Nebraska Bird Review
On the evening of 8 May 1997, I was scanning the shorebirds and ducks at the cattleyard basin of Sinninger WPA, York County. Most of the 300 or so puddle ducks were Bluewinged Teals (Anas discors), but also present were Green-winged Teal (A. crecca), American Wigeon (A. americana), Gadwall (A. strepera), Northern Shoveler (A. clypeata), and a Cinnamon Teal (A. cyanoptera). I eventually noticed a male duck in breeding plumage that superficially resembled a Baikal Teal (A. formosa). All descriptive discussion that follows is of male …
Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate
Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate
University of Nebraska State Museum: Mammalogy Papers
The southern short-tailed shrew, Blarina carolinensis, inhabits a broad range of ecological situations in the southeastern United States and, in many areas, is among the two or three most abundant species of small mammals. Nevertheless, its natural history is poorly known and much of what researchers assumed was fairly well understood about this species actually resulted from work on another species (Blarina brevicauda) and may not be correct in all instances. This problem resulted when modem systematic methods revealed that the wide-ranging and well-studied species known at that time as Blarina brevicauda actually consisted of three species …

Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel
Great Basin Naturalist
Species of Artemisia (subgenus Tridentatae) dominate much of western North America. The genetic variation that allows this broad ecological adaptation is facilitated by hybridization and polyploidization. Three separate studies were performed in this group using randomly amplified polymorphic DNA (RAPD). Fifty-seven 10-mer primers generated nearly 400 markers from genomic DNA obtained from leaf tissue. These studies were (1) a measure of the variability of plants within and between populations and between subspecies using 5 A. tridentata ssp. wyomingensis populations, 2 A. cana ssp. cana populations, and 1 A. cana ssp. viscidula population; (2) an examination of the hypothesis that …

The Evolution Of Primate Malaria Parasites Based On The Gene Encoding Cytochrome B From The Linear Mitochondrial Genome, Ananias A. Escalante, Denise E. Freeland, William E. Collins, Altaf A. Lal
Harold W. Manter Laboratory of Parasitology: Library Materials
We report a phylogenetic analysis of primate malaria parasites based on the gene encoding the cytochrome b protein from the mitochondrial genome. We have studied 17 species of Plasmodium, including 14 parasitic in primates. In our analysis, four species were used for rooting the Plasmodium phylogenetic tree: two from closely related genera (Hepatocystis sp. and Haemoproteus columbae) and two other Apicomplexa (Toxoplasma gondii and Theileria parva). We found that primate malaria parasites form a monophyletic group, with the only exception being the Plasmodium falciparum–Plasmodium reichenowi lineage. Phylogenetic analyses that include two species …
Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan
Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan
Vertebrate Pest Conference Proceedings: 18th (1998)
The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of sapling lodgepole pine (Pinus contorta) during spring periods in forests of interior British Columbia and Alberta, Canada. This damage may lead to mortality and reduced growth of crop trees in managed stands. Manipulation of stand density by pre-commercial thinning to densities < 1,000 stems/ha is an effective method to lower squirrel populations and feeding damage. Lowering stand density enhances the growth of crop trees, and understory herbs and shrubs as wildlife habitat, while protecting trees from squirrel feeding. This approach has been successful in several forest ecological zones. An alternative management tool is provision of diversionary food (sunflower seed) for those stands susceptible to feeding damage, and where stand thinning has already been completed. Diversionary food can be applied aerially and is very cost effective for protecting managed stands. These techniques may be used to maintain or even enhance species diversity of small mammal communities in those forest stands requiring protection.

Journal of the Arkansas Academy of Science
Since June 1982 we have studied various aspects of red bat ecology in Arkansas with emphasis on field work in the Ouachita Mountains and examination of specimens submitted to the Arkansas Department of Health Rabies Laboratory (ADHRL).This study reports on continued field work in the Ouachita Mountains using radiotelemetry and updates information regarding red bats submitted to the ADHRL through December 1996. In addition, we revisited a cave previously reported to contain a large number of red bat skull and skeletal remains. We also report remains from another cave system in northcentral Arkansas. These investigations have yielded additional information on …

Phorbol Ester Activation Of An Nhe-Like Electroneutral Na+ /H+ Antiporter In Isolated E-Cells Of Lobster (Homarus Americanus) Hepatopancreas, Jeff Duerr, Gregory A. Ahearn
Faculty Publications - Department of Biological & Molecular Science
The basolateral membrane of Atlantic lobster (Homarus americanus) epithelium possesses an electroneutral Na+ /H+ antiporter that functionally resembles members of the vertebrate NHE family. Regulatory mechanisms of this antiporter in purified hepatopancreatic E-cell suspensions, produced with a centrifugal elutriation technique, were investigated. Suspensions routinely consisted of greater than 95% E-cells displaying greater than 90% viability. Intracellular pH (pHi) was monitored by loading cells with the fluorescent dye 2´,7´-bis(carboxyethyl)-5,6- carboxyfluorescein (BCECF), and placing suspensions in a spectrofluorometer. Recovery from induced acid-loading was mediated by a Na+ -dependent, dimethylamiloride-sensitive proton efflux. Antiport activation was a sigmoidal function of pHi at values below …

A Study On The Zooplanktonic Fauna Of The Dam Lakeskunduzlar And Çatören (Kırka-Eskişehir), Ahmet Altindağ, Şakir Özkurt
Turkish Journal of Zoology
In the present study, the zooplanktonic fauna of the Kunduzlar and Çatören dam lakes (Kirka basin-Eskişehir) was investigated during August 1994-June 1995. Eight species of Rotifera, five species of Cladocera and two species of Copepoda were identified in both dam lakes. In addition, the mean zooplankton abundance (ind. m -3 ) and physical and chemical parameters of dam lakes were given.
Intraspecific Heterochrony And Life History Evolution: Decoupling Somatic And Sexual Development In A Facultatively Paedomorphic Salamander, Travis J. Ryan, Raymond D. Semlitsch
Intraspecific Heterochrony And Life History Evolution: Decoupling Somatic And Sexual Development In A Facultatively Paedomorphic Salamander, Travis J. Ryan, Raymond D. Semlitsch
Scholarship and Professional Work - LAS
Morphological features such as size and shape are the most common focus in studies of heterochronic change. Frequently, these easily observed and measured features are treated as a major target of selection, potentially ignoring traits more closely related to fitness. We question the primacy of morphological data in studies of heterochrony, and instead suggest that principal sources of fitness, such as life history characteristics, are not only the chief targets of selection, but changes in them may necessitate changes in other (subordinate) elements of the organism. We use an experimental approach to investigate the timing of metamorphosis and maturation in …

Highland Pond Utilization By Bats In The Ozark National Forest, Arkansas, J. D. Wilhide, Michael J. Harvey, V. Rick Mcdaniel, Vernon E. Hoffman
Journal of the Arkansas Academy of Science
During May through August 1996, wildlife ponds (man-made and/or naturally occurring) and road ruts on the Sylamore Ranger District, Ozark National Forest, Arkansas, were mist netted to determine extent of utilization by bats. Thirty-nine ponds and road ruts were netted one or more times during 53 nights. These water sources were originally constructed to support wildlife species such as deer, turkey, etc.. This study demonstrates that taxonomically and numerically diverse bat populations use these water sources. Seven hundred and seventy bats of nine species, including two endangered species, were netted. Bats were identified, and sex, reproductive status, forearm length, and …
Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James
Quantifying Community Separation And Increase In Number Of Avian Species With Corresponding Increase In Habitat Complexity, An African Example, Douglas A. James
Journal of the Arkansas Academy of Science
The relationship between increase in faunal diversity and corresponding increase in habitat complexity was quantified using shrubland bird communities in western Africa. Vegetational characteristics were measured in circular plots around bird positions. Bird species were then arranged from grassy open habitats to dense shrubland and found to be separated into three distinct communities when subjected to Duncan's multiple range procedure in conjunction with discriminant functions analysis. Random samples classified with respect to bird species showed there were few species in the more abundant open habitats and a disproportionate number of species were packed into the less common but complex shrubby …
Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross
Biological Sciences Theses & Dissertations
Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …
Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide
Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide
Journal of the Arkansas Academy of Science
Forty-one wildlife ponds were monitored between 1988 and 1992 for breeding use by wood frogs (Rana sylvatica). Data were collected on egg deposition and pond characteristics. Breeding activity and characteristics were similar to that reported in other portions of the range of the wood frog. We also monitored 15 newly-constructed ponds to determine chronological breeding patterns. Data collected for each site indicated a significant increase (P< 0.05) in the number of egg masses deposited in ponds as they age from 1-3 years during our study period. Increased chronological use of newly-constructed ponds may be due to localized population increase resulting from greater availability of breeding habitat
