Phylogenetic Systematic Analysis Of The Trichostrongylidae (Nematoda), With An Initial Assessment Of Coevolution And Biogeography, Eric P. Hoberg, J. Ralph Lichtenfels

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Phylogenetic analysis of the subfamilies of the Trichostrongylidae based on 22 morphological transformation series produced a single cladogram with a consistency index (CI) = 74.2%. Monophyly for the family was supported by the structure of the female tail and copulatory bursa. Two major clades are recognized: the Cooperiinae clade with the basal Cooperiinae and Libyostrongylinae + Trichostrongylinae, and the Graphidiinae clade with the basal Graphidiinae and Ostertagiinae + Haemonchinae. Dendrograms presented by Durette- Desset (1985) (CI = 56.1%) and Lichtenfels (1987), based on the key to the Trichostrongylidae by Gibbons and Khalil (1982) (CI = 59.0%), were found to be …

The Warnbro Sound Crab Fishery Draft Management Plan., Fiona Crowe

Fisheries management papers

In recent years fishing effort for the blue summer/manna crabs (Portunus pelagicus) in Warnbro Sound has increased dramatically and concerns have been raised about the state of stocks of crabs in Warnbro Sound. As a result of the increased pressure being put on the limited resource, the relationship between professional and recreational user groups has become sensitive. It is therefore appropriate that measures ensure the responsible management of the Warnbro Sound Crab Fishery be introduced. Gear, bag limit and size restrictions on the taking of blue swimmer crabs by recreational fishermen already exists as part of the the overall recreational …

Using Biodiversity Data To Assess Species--Habitat Relationships In Glacier National Park, Montana, Diane M. Debinski, Peter F. Brussard

Diane M. Debinski

Biodiversity surveys are becoming increasingly popular. However, standard analysis techniques for these data have not yet been developed. This paper explores the use of multivariate ordination techniques for assessing species—habitat relationships using biodiversity data. The research was conducted in Glacier National Park, Montana, and birds and butterflies were chosen as the taxonomic groups of study. Biodiversity assessment sites were established throughout a range of habitats and monitored from 1987 through 1989. Presence/absence sampling over the total number of sampling sites was used to classify species commonness and rarity. Approximately 86% of the historically recorded butterflies and 70% of the historically …

Rock Lobster Industry Advisory Commitee Chairman's Report, October 1994 - The Western Rock Lobster Fishery - Management Proposals For The 1994/95 And 1995/96 Seasons, Rock Lobster Industry Advisory Committee, Peter Rogers

Fisheries management papers

The failures of past restrictions on fishing effort to fully halt the decline of the breeding stock led to the formation of a sub-committee of the Rock Lobster Industry Advisory Committee. The prime objective of the sub-committee is to evaluate effective long term strategies for managing the fishery so that breeding stock is maintained at an adequate level despite the inevitable increases in catching efficiency. The purpose of this report is firstly to advise industry of the management proposals for the 1994/95 seasons and secondly to form a basis for industry consultation on management arrangements for the 1995/96 season.

Long Term Management Strategies For The Western Rock Lobster Industry (4 Volumes) - Economic Efficiency Of Alternative Input And Output Based Management Systems In The Western Rock Lobster Fishery (Volume 2), Bob Lindner

Fisheries management papers

Since 1965, the Western Rock Lobster Fishery has been managed by what is essentially a license limitation scheme invoiving restricted entry for boats, and strict controls on the aggregate number of pots which can be used by the commercial fishing sector. By most measures, management of this fishery has been highly successful. Biological over-exploitation of the fish stock has been prevented, at least until recently. Notwithstanding these achievements, there is widespread concern that the future profitability, and even the viability of the industry is under threat unless the current management practices are reformed. Because of the complexity and intrinsic uncertainty …

Long Term Management Strategies For The Western Rock Lobster Fishery (4 Volumes) - A Market-Based Economic Assessment For The Western Rock Lobster Industry (May 1994) (Volume 3), Marec Pty Ltd

Fisheries management papers

In October 1992 a special Sub-Committee of the Rock Lobster Industry Advisory Committee was set up to consider and evaluate future management strategies for the rock lobster fishery. Pursuant to this the Director of Fisheries commissioned a marketing study that is the basis of this report. This study was commenced in early October 1993 and completed in May 1994. This study looked at the market implications of fishery's management strategies. In particular it assesses how the existing management structure limits the potential for the lobster industry to maximise the financial return, and in doing so provides an insight into the …

Aboveground Biomass And Net Primary Production Along A Virginia Barrier Island Dune Chronosequence, John Joseph Dilustro

Biological Sciences Theses & Dissertations

Aboveground biomass was examined along a chronosequence of dune communities on Hog Island, a Virginia Coast Reserve LTER site. The dominant species were Ammophila breviligulata and Spartina patens. Aboveground biomass was harvested monthly from ten quadrats on dunes 6, 24, 36, and 120 years old. Sampling was conducted from April to November 1993. Biomass values were greater for younger dunes. Total aboveground biomass decreased with increasing site age and ranged from 152 g m^-2 on the 120 year old dune to 205 g m^-2 on the 6 year old dune in October 1993. Spartina patens biomass was …

Seasonal Composition Of Mesozooplankton In The Pagan River, A Nutrient Enriched Virginia Estuary, Lillian Norman Davis

Biological Sciences Theses & Dissertations

A two year study of the mesozooplankton composition and seasonal distribution was conducted in the Pagan River, a nutrient rich tidal estuary and tributary to the lower James River. The mesozooplankton was dominated by calanoid copepods (80%), with the total zooplankton abundance peaks occurring during spring and fall. The total mean abundance, 3008/m', was somewhat lower than those found by other authors, however the mean abundance at one station approximated those means. Seventy-eight percent of the calanoid copepods were Acartia spp. that were primarily responsible for the fall increase in mesozooplankton abundance. The spring increase was primarily due to increases …

Seasonal Phytoplankton Dynamics In The Pagan River, David Wade Seaborn

Biological Sciences Theses & Dissertations

The composition and seasonal abundance patterns for phytoplankton in the Pagan River, Virginia, were determined. This river is characterized as a nutrient enriched system with annual mean levels of total nitrogen and phosphorus at 1.8 and 0.8 mg/I respectively. Three phytoplankton maxima occurred during the year with the highest in fall, followed by summer and spring peaks. A diatom flora was dominant throughout the year at concentrations of 107 to 108 cells/I. Other algal populations exhibited distinct periods of abundance, which seasonally varied in magnitude and time of development. Turbidity levels were high throughout the year, with a mean secchi …

The Effect Of Nitrogen Fertilization On The Phenology Of Roots In A Barrier Island Sand Dune Community, Everett P. Weber

Biological Sciences Theses & Dissertations

Little work has been done on the phenology of root growth and senescence largely due to methodological difficulties. The application of minirhizotron technology has enabled the tracking of individual roots through an entire growing season. As a result, direct measures of turnover, root growth, and an analysis of cohorts were made. Small plots on a 36 year old dune on Hog Island, a barrier island in the Virginia Coast Reserve Long Term Ecological Research Site, were fertilized with nitrogen. Minirhizotron tubes were installed in each fertilized and control plot. Each tube was sampled monthly for nine months, March through October …

Eutrophication And Macrobenthic Communities Of The Lower Chesapeake Bay: Effects Of Organic Enrichment In Pocomoke Sound, Saxis Virginia, Janice D. Mcdonnell

Biological Sciences Theses & Dissertations

The effects of organic enrichment on benthic community structure were evaluated in a field study conducted in Pocomoke Sound in the vicinity of a seafood processing plant. The empirically derived Species Abundance and Biomass (SAB) curves of Pearson and Rosenberg (1978) were used to model patterns of organic enrichment at the study site, called Pig Point, as well as two reference sites located within Pocomoke Sound. The Split Moving Windows (SMW) method was used to detect the ecotone point as defined in the Pearson and Rosenberg (1978) model and the Two Term Local Quadrat Variance (TTLQV) method was used to …

Open Corridors In A Heavily Forested Landscape: Impact On Shrubland And Forest-Interior Birds, Robert A. Askins

Biology Faculty Publications

In eastern North America, remnant patches of forest surrounded by open habitat constitute unfavorable habitat for many species of migratory forest birds because of high rates of nest predation and cowbird parasitism. Although most evidence for this relationship comes from 'forest islands' surrounded by residential or agricultural land, even forest patches isolated from other forests by narrow open corridors such as roads and powerline rights-of-way seem to show this pattern. Productive habitat for migratory birds can be maintained by consolidating corridors and routing them along the periphery of forests to retain as much continuous forest as possible. Consolidation of open …

Benthic Community Responses To Hypoxic Conditions In The Lower Rappahannock River, Virginia, Mary Elaine Smith

Biological Sciences Theses & Dissertations

The effects of seasonal low dissolved oxygen conditions upon benthic macroinvertebrate communities were studied in the lower Rappahannock River, a tributary of the Chesapeake Bay. Benthic communities were sampled during March, June, August, and September 1993 at five equidistant depths (5, 10, 15, 20, and 25 m) extending upwards from the deepwater Virginia Benthic Biological Monitoring Station LE3.4 located in the deep basin just inside the mouth of the Rappahannock River. Infaunal species diversity, richness, biomass, and density were measured along with the vertical depth distribution of organisms within the sediment. Significant sediment differences were found between the shallowest, 5 …

Testing Hypotheses About Evolutionary Change On Single Branches Of A Phylogeny Using Evolutionary Contrasts, Mark A. Mcpeek

Dartmouth Scholarship

Interspecific comparisons of phenotypes are used extensively to test hypotheses about the evolutionary forces shaping phenotypic variation, but comparative data analysis is complicated by correlations due to the common ancestry of species. The method of evolutionary contrasts removes such correlations by estimating the amount of character change between pairs of closely related species that has occurred since their most recent common ancestors. The original method allows character change to be estimated only along pairs of branches on a phylogeny, but many hypotheses address change along single branches. In this article the method of evolutionary contrasts is extended to allow character …

Black Bear Habitat Use In Great Smoky Mountains National Park, Frank Teunissen Van Manen

Doctoral Dissertations

I used telemetry locations of American black bears (Ursus americanus), collected in Great Smoky Mountains National Park (GSMNP) from 1976 to 1982 , to evaluate home ranges, movements, and habitat use. Annual home range estimates averaged 7.6 km² (SD = 7. 1) for females and 48.5 km² (SD = 2 1 . 1) for males. For both sexes, fall ranges were larger than summer ranges and shifts occurred between summer and fall centers of activity. Annual and seasonal changes in spatial use of black bears are largely explained by changing activity and movement patterns in response to variation …
