Trophic Diversity Of A Mesopelagic Fish Community., Tracey Sutton, Thomas L. Hopkins, Thomas M. Lancraft

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

To understand the character of prey partitioning in a low latitude oligotrophic region, a composite picture of the trophic structure of a mesopelagic fish community was made from the eastern Gulf of Mexico. Two hundred and twenty three species were collected in the area of which I61 species were abundant enough for analyses. Fifteen major categories of prey biomass are identified for diet analyses: viz. copepods, ostracods, amphipods, euphausiids, decapods, larvaceans, salps, coelenterates (primarily siphonophores), unidentified gelatinous prey, polychaetes, gastropods, cephalopods, chaetognaths, fish, other food. Prey partitioning is minimal across major prey categories as the vast majority of mesopelagic fishes …

Tallgrass Prairie Remnants Of Western Iowa Cemeteries., Carrie L. Menges-Schaben

Student Work

Tallgrass prairie remnants situated in eight western Iowa cemeteries were sampled during 1995 and 1996 to compare both the frequency and season of mowing and burning on plant species composition. Dominant, native tallgrass prairie species, such as big bluestem (Andropha gerardii), Indian grass (Sorghastrum nutans) and leadplant (Amorpha canescens), generally showed a significant increase with burning, whether mowed or not. Mowing, however, adversely affected other species, including flower spurge (Euphorbia corollate) and porcupine grass (Stipa spartea), whether burned or not. Non-native species, in particular smooth brome (Bromus inermis) increased with mowing and the absence of fire. Overall, my study suggests …

Why Foster Parents Continue And Cease To Foster, Nolan Rindfleisch, Gerald Bean, Ramona Denby

The Journal of Sociology & Social Welfare

This study addressed the following question: What factors thought likely to influence the license status of foster family homes predict to continuing and what predict to ceasing to foster? This study was conducted in eight urban counties in a large Midwestern state. Using logistic regression, a 13 variable model was developed. The factors with odds ratios that predicted greater likelihood of closed license status were: when the foster mother is white, respondent wanting to adopt but being unable to do so, concern about agency red tape, disagreement with the statement that social workers reached out to foster parentsand respondents not …

Permutation Of Two-Term Local Quadrat Variance Analysis: General Concepts For Interpretation Of Peaks, Jonathan E. Campbell, Scott B. Franklin, David J. Gibson, Jonathan A. Newman

Publications

Many ecological studies use Two-Term Local Quadrat Variance Analysis (TTLQV) and its derivatives for spatial pattern analysis. Currently, rules for determining variance peak significance are arbitrary. Variance peaks found at block size 1 and at > 50 % of the transect length are the only peaks whose use is explicitly prohibited. Although the use of variance peaks found at block sizes > 10 % of the transect length have also been warned against, many researchers interpret them regardless. We show in this paper that variance peaks derived from TTLQV are subject to additional ‘rules of thumb’. Through the use of randomization and …

An Experimental Reef Program To Test Designs Of An Artificial Reef For Kelp Mitigation, Larry Deysher, Thomas A. Dean, Robert Grove, Andy Jahn

Gulf of Mexico Science

An artificial reef is being planned to mitigate alleged losses of giant kelp and the invertebrate and fish communities associated with a kelp bed. The project's first step was to initiate comprehensive siting and design studies. A 25-yr time series of kelp surface canopy maps for a 100 km reach of coastline was entered into a GIS database and analyzed in conjunction with geotechnical and human-use information to define ecologically favorable and acceptable sites in the general area. A site was chosen near an area that appeared most promising in the primary study area. This study's field work determined that …

Comparison Of Presettlement And Present Vegetation Cover Of Marion County, Illinois Using A Geographic Information System, Daniel Unger

Faculty Presentations

The vegetation types of Marion County, Illinois prior to European settlement, which were derived from soil association surveys, were compared to a satellite map of current vegetation types to quantify their change over time. GIS analysis indicates that 10% of presettlement prairie is currently grassland, 2% of presettlement prairie has been converted to forest, 32% of original prairie has been converted to agriculture and urban use, 17% of presettlement forest remains intact, grassland comprises 18% of presettlement forest while 21% of presettlement forest has been converted to agricultural and urban use.

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 …

Terminal Restriction Fragment Patterns (Trfps), A Rapid, Pcr-Based Method For The Comparison Of Complex Bacterial Communities, Brian G. Clement, Lucia E. Kehl, Kristin L. Debord, Christopher L. Kitts

Biological Sciences

Microbial populations in complex environmental samples are difficult to characterize; current techniques are incomplete and time consuming. We investigated a polymerase chain reaction (PCR)-based method for rapidly comparing bacterial communities independent of culture or cloning. Community 16S rRNA genes were amplified and fluorescently labeled by PCR. The labeled products were digested by a restriction enzyme and the labeled, terminal restriction fragments (TRFs) were separated by electrophoresis and detected by laser-induced fluorescence on an automated gene sequencer. PCR parameters were optimized using an in vitro model community of known organisms. Community comparisons were made between deer fecal pellets, petroleum hydrocarbon-contaminated sands …

Social And Biological Aspects Of Non-Native Red Fox Management In California, Jeffrey C. Lewis, Kevin L. Sallee, Richard T. Golightly Jr., Ronald M. Jurek

Vertebrate Pest Conference Proceedings: 18th (1998)

Since the late 1800s, non-native red foxes have been introduced in California for fur farming and fox hunting. Dispersal, population growth, and extensive translocations by humans have aided the expansion of the nonnative fox population throughout many of the lowland and coastal areas of the state. Since the 1980s, non-native red foxes have been recognized as predators of a number of endangered species. Trapping and euthanizing non-native red foxes have been used as methods to protect these endangered species, but have been opposed by some members of the public. Opposition by animal rights groups to red fox trapping and euthanization …

Twenty-Five Years Of Managing Birds Associated With Buildings At The University Of California, Berkeley, Arthur J. Slater

Vertebrate Pest Conference Proceedings: 18th (1998)

Information concerning 19 species of birds associated with 28 buildings on the University of California at Berkeley campus has been collected for 25 years. Sixteen species are included under three minor associations (temporary roosters, building invaders, and species that nest on (or in) buildings in small numbers). Barn owls and ravens have caused intense, though localized problems. Two additional species (cliff swallows and feral pigeons) have caused major problems. Feral pigeons have caused the most difficult problems to resolve. Case histories are used to describe problems associated with these birds, and control strategies for them. Cooper's hawks have nested in …

Glossina Fuscipes Fuscipes Newstead 1910 (Diptera, Glossinidae): Colour Preferences, Host-Funding Strategies And Responsiveness To Baited Traps, Jean-Berckmans Bahananga Muhigwa

All PhD Dissertations

This study was conducted on Glossina fuscipes fuscipes, a riverine species of Central and Eastern Africa. It focuses on (i) colour preferences, (ii) landing and feeding behaviours on a host, the Nile monitor and (iii) on the trappability in odour- and colour-baited traps. Colour preferences were studied using electric screens in the field. Colours that were found most attractive were combined to make traps. These traps were tested as visual baits, compared to the standard biconical trap Challier Laveissiere (1977). The performance of the most successful trap type was analyzed in relation with fly sex and fly abundance. It was …

Ecologic Studies Of Rodent Reservoirs: Their Relevance For Human Health, James N. Mills, James E. Childs

Zoonotics and Wildlife Disease: Publications

Within the past few years, the number of “new” human diseases associated with small-mammal reservoirs has increased dramatically, stimulating renewed interest in reservoir ecology research. A consistent, integrative approach to such research allows direct comparisons between studies, contributes to the efficient use of resources and data, and increases investigator safety. We outline steps directed toward understanding vertebrate host ecology as it relates to human disease and illustrate the relevance of each step by using examples from studies of hosts associated with rodent-borne hemorrhagic fever viruses.

Mammalian Reservoirs And The Changing Epidemiology Of Rabies In The United States, James E. Childs, John W. Krebs, Charles E. Rupprecht

Vertebrate Pest Conference Proceedings: 18th (1998)

The epidemiology of rabies in the United States has changed dramatically over the past few decades. Greater than 90% of all animal rabies cases reported annually to the Centers for Disease Control and Prevention now occur in wildlife, whereas before 1960 the majority were domestic animals. The principal rabies reservoirs today are wild carnivores and bats, infected with many different types of rabies virus variants. Annual reporting of human deaths have fallen from more than 100 at the turn of the century to one to six per year, despite major outbreaks of animal rabies in several distinct geographic areas. Most …

Education's Role In Sustainable Development: Uganda's Kibale National Park, R. J. Lilieholm, K. B. Paul, T. L. Sharik, R. Loether

Natural Resources and Environmental Issues

Kibale National Park (KNP), located in western Uganda, offers a rich diversity of tropical flora and fauna. The Park’s mid-altitude, moist tropical forest supports 11 of Uganda’s 20 non-human primate species, some of which occur in very high densities. The region around KNP is home to seven national parks and numerous protected areas. Located within KNP is the Makerere University Biological Field Station (MUBFS), with an extensive 25-year research history and a mandate to assist KNP in protecting the ecosystems of the region through management-relevant research. While KNP and MUBFS have received much visibility within Uganda, East Africa and the …
