Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan

Biological Sciences Theses & Dissertations

Loblolly pine plantations were examined at different ages to identify small mammal community attributes in relation to the succession of the plant community. Forest floor and understory plant communities were characterized. Small mammals were collected by Fitch (live) traps and pitfall traps in four age classes during five seasons of study. Fitch live traps and pitfall traps were used in conjunction with one another to obtain the most accurate depiction of the small mammal community. Fitch traps accounted for 65 % of small mammal captures and 7 of 9 species captured. Small mammal abundance and biomass declined with increasing stand …

In the first section, an option for enhancing the catch value by transferring lobsters …

Fisheries Research Report No. 110 - A Research Vessel Survey Of Bottom Types In The Area Of The Abrolhos Islands And Mid-West Trawl Fishery., C. J. Dibden, L. M. Joll

Fisheries Research Reports

To address the concern expressed by Commercial rock lobster fishers operating in the Abrolhos Islands area, that expanding saucer scallop trawl activity was damaging the sea floor biota in areas which they considered good rock lobster habitat and poor scallop habitat, an underwater video survey was conducted by the Fisheries Department Research Division, with the following objectives:

1. Examine, classify and map the benthic habitat of areas currently and historically trawled for scallops in the Abrolhos Islands area and adjacent waters;

2. Examine, classify and map the benthic habitat of areas adjacent to these trawled areas, where potential for conflict …

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, …

A Comparison Of Encephalization Between Odontocete Cetaceans And Anthropoid Primates, L. Marino

Veterinary Science and Medicine Collection

There have been very few studies of brain size and encephalization in cetaceans and essentially none that have made direct quantitative comparisons of cetaceans and another mammalian group using large normative samples. In the present study two different measures of encephalization were calculated and used to rank and compare 21 odontocete species and 60 anthropoid primate species. Comparisons were made both within and between the two groups. Results show that the encephalization level of Homo sapiens is still extraordinary relative to that of nonhuman species. Nevertheless, a subset of delphinid odontocetes are significantly more highly encephalized than the most highly …

Effect Of Sampling Errors On Estimates Of Recruitment And Fishing Mortality From Separable Virtual Population Analysis, Emmanis Dorval

Biological Sciences Theses & Dissertations

Separable virtual population analysis (SVPA) models provide estimates of historical recruitment and fishing mortality from analyzing catch data based on the separability of fishing mortality into age specific-gear selection and yearly mortality. These models assume that the catch is randomly sampled and that sampling error is a random variable with constant variance and mean equal to zero. These models do not account for sampling measurement errors that occur when the catch partitioned by age is not measured on every sampling unit without error, and spatio-temporal errors that occur when the observed catch is not representative of the harvested population throughout …

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 …

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 …

Ecology And Natural History Of The Cow Knob Salamander, Plethodon Punctatus Highton, In West Virginia, Robert B. Tucker

Theses, Dissertations and Capstones

Very little has been written on the ecology and natural history of the Cow Knob salamander, Plethodon punctatus Highton, since it was described by Highton (1971). Plethodon punctatus is known only from the higher elevations of Great North (above 2,800 ft) and Shenandoah (above 3,000 ft.) Mountains in Virginia and West Virginia (Highton, 1972; Conant and Collins, 1991). The type locality is Cow Knob, Pendleton County, West Virginia. Plethodon punctatus is a large (up to 75 mm snout-to-vent length) dorso-ventrally flattened salamander with creamish iridiophore spots on the back and sides, webbed feet for a fossorial lifestyle, and large …

The Use Of Emergent Rocks As Refugia For The Cheat Mountain Salamander, Plethodon Nettingi Green, Beth Anne Pauley

Theses, Dissertations and Capstones

Plethodon nettinqi was listed as a threatened species in 1989 by the United States Fish and Wildlife Service (Pauley, 1991). Its total range is within 5 counties in eastern West Virginia. There are fewer then 60 disjunct populations known and most populations are above 3,000 ft. and are associated with emergent rocks or narrow ravines with Rhododendron. It is hypothesized the P. netting! survived lumbering practices at the turn of the century by taking refuge beneath large emergent rocks and narrow ravines with Rhododendron. This study examined environmental factors associated with emergent rocks that might regulate the distribution of P. …

The Use Of Isoelectric Focusing To Assess The Genetic Diversity Of The Cyprinid Fishes: Rhinichthys Cataractae And Rhinichthys Atratulus In West Virginia, Fauzia Alam Miah

Theses, Dissertations and Capstones

In this study, isoelectric focusing is used to separate proteins of Rhinichthys cataractae and R. atratulus and conventional staining is used to identify alleles of six genes. The objective of this work is to determine whether these methods can effectively assay isozymes that may be used to establish the relationship between anthropogenic stress and genetic diversity. Alleles for LDH-A, LDH-B, EST-A, EST-B, EST-C, and EST-D loci were identified for two species of fish, R. atratulus and R. cataractae. Both fish species are known to be sensitive to anthropogenic stress and known to be widely distributed in stressed environments. Alleles …

These results indicated a bivoltine life cycle. Most larvae were found in the spring and summer months of April, June, and July. The highest peak of larvae (1,035) occurred in July. The pH values ranged from 7.0 to 8.0 with a mean of 7.6. Temperatures ranged …

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.

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

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 …

Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill

Biology Faculty Publications

The larval chondrocranium and visceral skeleton of Dendrobates auratus ls described and compared with those of other dendrobatids. Four characters, i.e. lack of fusion between orbital cartilages and otic capsules, wide processus muscularis palatoquadrati, lack of processus pseudopterygoideus, and lack of processus anterolateralis hyalis, represent derived conditions for Dendrobates within Dendrobatidae. Cranial and postcranial ossification sequences are reported for D. auratus and Epipedobates tricolor. Skeletogenesis is earlier in E. tricolor, but the overall pattern of ossification is similar in the two species.

The Role Of Bowfin, Amia Calva, In Multiple Species Management Plans, Benjamin Jacob Hausmann

Masters Theses

The major challenge to fisheries managers of the 21st century will be to maintain the diversity, not only of fishing opportunity, but also of traditionally non-game and economically unimportant species. With the relatively recent understanding of the importance of ecosystem level management, attention is being focused on native species that were often ignored or eradicated under past management practices. One such fish that has been largely ignored is the bowfin, Amia calva. Ecological data pertaining to bowfin natural history are limited and to date no attempt has been made to integrate bowfin into fisheries management decisions within the species native …

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

In-Stream Monitoring Of Sediments And Water In The Lower Ouachita River For Site Impact To Aquatic Biota, Jerry L. Farris, J. T. Knight, C. D. Milam, F. Buzen, J. F. Nix

Journal of the Arkansas Academy of Science

Reported reduced sportfish densities in the main channel of the Ouachita River prompted an investigation, beginning in 1990, into potential causes of ongoing impairment to aquatic biota. In-stream monitoring that incorporated toxicity testing of sediments and water was conducted to discern potential sources of contaminants that might be related to the suboptimal fishery populations. Organisms selected to evaluate chronic impairment included larval fish, clams, midges and water fleas. The fathead minnow {Pimephales promelas) and cladoceran (Ceriodaphnia dubid) were used to estimate patterns of toxicity associated with water from seven designated reaches and selected tributaries of the Ouachita River. Larval survival …

Telemetric Observations Of Foraging Ozark Big-Eared Bats In Arkansas, J. D. Wilhide, V. Rick Mcdaniel, Michael J. Harvey, Daniel R. White

Journal of the Arkansas Academy of Science

Ozark big-eared bat (Corynorhinus townsendii ingens) foraging activities were studied during 1995 in Marion County, Arkansas. Adult bats were equipped with radiotransmitters and tracked during June and July. Foraging activities were generally within 1 kilometer (km) of the roost cave. Male bats ranged farther than females with the exception of one female that flew 2.5 km into a different watershed. Male big-eared bats and northern long-eared bats (Myotis septentrionalis) were also found within the maternity colony.
