Phylogenetic Relationships Of African Microhylid Frogs Inferred From Dna Sequences Of Mitochondrial 12s And 16s Rrna Genes, Simon P. Loader, David J. Gower, Kim M. Howell, Nike Doggart, Mark-Oliver Rödel, Barry T. Clarke, Rafael O. De Sá, Bernard L. Cohen, Mark Wilkinson

Biology Faculty Publications

The phylogenetic relationships of microhylid frogs are poorly understood. The first molecular phylogeny for continental African microhylids is presented, including representatives of all subfamilies, six of the eight genera, and the enigmatic hemisotid Hemisus. Mitochondrial 12S and 16S rRNA sequence data were analysed using parsimony, likelihood and Bayesian methods. Analyses of the data are consistent with the monophyly of all sampled subfamilies and genera. Hemisus does not nest within either brevicipitines or non-brevicipitines. It is possibly the sister group to brevicipitines, in which case brevicipitines might not be microhylids. Phrynomantis and Hoplophryne potentially group with non-African, non-brevicipitine microhylids, in …

Immunotoxicological Study Of Depleted Uranium, Bin Wan

Doctoral Dissertations

The purpose of this study was to examine toxicity of depleted uranium (DU) to the immune system and the gene expression profile of DU-exposed immune cells including peritoneal macrophages, primary CD4⁺ T-cells and T Cell Hybridoma (TCH) PLP1 5B6. Flow cytometry analysis of annexin-V and Propidium Iodide (PI) binding revealed that DU causes death in those cells at various concentrations. The non-cytotoxic concentrations of DU determined in macrophages, primary CD4⁺ T-cells, and T cells hybridoma are 50µM, 100 µM, and 500 µM, respectively. Findings also revealed that DU-exposed macrophages are able to promote CD4⁺ T-cell proliferation in …

The Role Of History In The Diversification Of The Funnel-Web Spiders, Agelenopsis Aperta, And Its Congeners, Nadia Antoine Ayoub

Doctoral Dissertations

Identifying the influence of history on the diversity of life is an important goal of evolutionary biology, whether it is an historical event that is extrinsic to the organism such as past climate change or an intrinsic event such as a single switch in behavior. Phylogenetic trees offer an indirect record of the history of diversification in a group of organisms and can be used in conjunction with other information to deduce the multiple roles of history affecting a particular group. Intra- and inter-specific phylogenetic relationships in the spider genus Agelenopsis Geibel (Araneae: Agelenidae) were analyzed using sequence data from …

An Analysis Of The End-Of-Life Choices Of Elderly Patients And Their Healthcare Providers At A Community Hospital In Tennessee, Elizabeth Harder Dobbins

Doctoral Dissertations

The Patient Self-Determination Act of 1990 was expected to popularize the use of advance directives (living wills and durable powers of attorney for healthcare (DPOA-HC)). Since the law was passed, researchers have found that the use of the documents has not increased as expected and that the documents, when present, were not always respected by healthcare providers.

The purpose of this study was to analyze the end-of-life choices of elderly patients and their healthcare providers in a community hospital setting. The subjects of this study were 160 patients, aged 65 years and older, who died in a community hospital in …

Origin And Evolution Of Large Brains In Toothed Whales, Lori Marino, Daniel W. Mcshea, Mark D. Uhen

Veterinary Science and Medicine Collection

Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontocete superfamily Delphinoidea (dolphins, porpoises, belugas, and narwhals) comprises numerous species with encephalization levels second only to modern humans and greater than all other mammals. Odontocetes have also demonstrated behavioral faculties previously only ascribed to humans and, to some extent, other great apes. How did the large brains of odontocetes evolve? To begin to investigate this question, we quantified and averaged estimates of brain and body size for 36 fossil cetacean species using computed tomography and …

The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom

Animal Welfare Collection

The publication of Rachel Carson’s Silent Spring in 1962 is widely regarded as one of the major events that launched the modern environmental movement. Silent Spring is a compelling blend of stories, natural history, human values, and biological facts. In this essay we consider Carson’s attitude toward animals in Silent Spring and in other texts. Despite the facts that she was raised to love Nature and animals, little direct attention has been given to Carson’s views about our moral responsibilities to, and the moral standing of animals. Carson favored responsible stewardship, was more of an animal welfarist and environmentalist/conservation biologist …

A total of 200 questionnaires were collected. Participants were randomly assigned to one of four groups. Each group of 50 participants was exposed to a specific set of online atmospheric elements. The results indicated that Hypotheses 1, 3 and 4 were rejected while Hypotheses 2 …

The Dynamics, Distribution, And Activity Of Viruses In Lake Erie, Amanda Dean

Masters Theses

As viruses-- specifically pervasive pathogens of aquatic microorganisms-- are now included in most studies of aquatic food webs and nutrient cycles, presented here is new information from samples collected in July 2003 which demonstrates that bacteria lysed by viruses released 122 - 1080 nM of phosphorus per day throughout Lake Erie, implying that viruses acted as a major mechanism of phosphorus recycling in the lake. Viruses have been shown to be ubiquitous throughout Lake Erie, with a weak correlation between their distribution and the distribution of bacteria. Moreover, evidence suggests that virus production rates are tightly tied to the growth …

Comments On Eusopondis And Proctoporus (Squamata: Gymnophthalmidae) From Peru, With The Description Of Three New Species And A Key To The Peruvian Species, Edgar Lehr, Gunther Kohler

Edgar Lehr

We describe two new species of Proctoporus and a new species of Euspondylus (all from central Peru, Departamento de Huanuco, 2545 to 3010 m elevation). The new species are distinguished from all species presently assigned to Proctoporus and Euspondylus by unique characteristics of pholidosis, morphometrics, and color pattern. A key to the Peruvian species of Proctoporus and Euspondylus is provided. The current allocation of species to Proctoporus and Euspondylus may not reflect the phylogenetic relationships of the species under consideration. Based on the available data there appears to be no evidence to justify the separation of these genera. However, because …

Lexen: Role Of Atmospheric Trace Gases In Microbial Colonization And Succession On Recent Lava Flows, Gary M. King

University of Maine Office of Research Administration: Grant Reports

Drs. Gary M. King of the University of Maine and Klaus Nusslein of the University of Massachusetts-Amherst have been awarded a grant from the NSF Life in Extreme Environment (LExEn) program to determine the role of atmospheric trace gases in microbial colonization and succession on recent lava flows. Volcanic activity has played an important role in the development of terrestrial ecosystems for much of Earth's history, and continues to shape terrestrial environments at present. Deposition of lava and tephra result in surfaces that over time support complex, highly productive biological communities. However, young or recently extruded lavas represent extreme environments …

Predators In Natural Fragments: Foraging Ecology Of Wolves In British Columbia’S Central And North Coast Archipelago, C. T. Darimont, M. H. H. Price, N. N. Winchester, J. Gordon-Walker, P. C. Paquet

Biogeography and Ecological Opportunity Collection

Aim Predator–prey dynamics in fragmented areas may be influenced by spatial features of the landscape. Although little is known about these processes, an increasingly fragmented planet underscores the urgency to predict its consequences. Accordingly, our aim was to examine foraging behaviour of an apex mammalian predator, the wolf (Canis lupus), in an archipelago environment.

Location Mainland and adjacent archipelago of British Columbia, Canada; a largely pristine and naturally fragmented landscape with islands of variable size and isolation.

Methods We sampled 30 mainland watersheds and 29 islands for wolf faeces in summers 2000 and 2001 and identified prey remains. We examined …

Apparent Sibling Rivalry In The Freshwater Clam Sphaerium Striatinum, Mark Beekey, Ronald H. Karlson

Biology Faculty Publications

In Sphaerium striatinum, a freshwater brooding bivalve, up to 97.5% of offspring that adults initially produce fail to reach independence. Marsupial sacs, specialized extensions of gill filaments that act as nurseries, initially contain multiple offspring in various sizes and stages of development. However, by the time offspring reach later stages of development, marsupial sacs typically contain only one offspring. Brood mortality is hypothesized to be the result of competition among embryos for nutrients and/or space. Sphaeriid eggs do not contain enough yolk for offspring to complete development. Adults supply additional nutrients required to reach independence. Brood capacity is limited by …

There are 146 kinds of species have been found for the total catches, most of the operating area were located at the center of the sea in which the thermal effluent …

A Trophic Model For Kuosheng Bay In Northern Taiwan, Hsing-Juh Lin, Kwang-Tsao Shao, Jiang-Shiou Hwang, Wen-Tseng Lo, I-Jiunn Cheng, Lih-Huwa Lee

Journal of Marine Science and Technology

Using the Ecopath with Ecosim software system, a mass-balanced trophic model of Kuosheng Bay, where the Second Nuclear Power Plant is sited on the coast, was constructed. This model comprised 17 compartments, ranging from a trophic level of 1.00 for primary producers and detritus to 3.97 for piscivorous fish. The geometric mean of the trophic transfer efficiencies was 6.5%. The lower efficiencies were attributable to high flows to detritus, suggesting that the food web was more dependent on detritus than on primary producers to generate total system throughput. The total system throughput, system production, and system biomass were comparable to …

Effects Of Nuclear Power Plant Thermal Effluent On Marine Sessile Invertebrate Communities In Southern Taiwan, Yalan Chou, Ta-Yu Lin, Chen-Tung Arthur Chen, Li-Lian Liu

Journal of Marine Science and Technology

The present study aimed at determining the impact of cooling water discharge from a Nuclear Power Plant in Kenting, Taiwan on the recruitment patterns of marine invertebrates. Field experiments were conducted over a six-year period in the vicinity of the power plant, with six control sites, five at influent areas, one at reference site, and three experimental sites at effluent areas. In general, among the monitoring sites, polychaetes and bryozoans were the most abundant organisms, and their recruitment on settlement plates was always higher in influent than in effluent areas. Partially as a result of a 5-week accidental shutdown of …

The Coastal Currents Offshore The Nuclear Power Plants At Northern Taiwan, Jian-Hwa Hu

Journal of Marine Science and Technology

Coastal tidal currents play an important role to disperse the warm waters outlet from cooling system of a nuclear power plant (NPP). The modern technique of ship-board acoustic Doppler current profiler (SB-ADCP) was intensively applied to scan the current fields around the three NPPs at northern Taiwan. Sophisticated data processing provides time series of synoptic flow charts of vectors in grids associated with streamlines, allowing the visualization of how the bay like coastline input its boundary layer effect to the current field. The generation of cyclonic or anti-cyclonic vortices inside the bay in flood or ebb tide and their migration …

Hydrographical Studies Of Waters Adjacent To Nuclear Power Plants I And Ii In Northern Taiwan, Tien-Hsi Fang, Jing-Fang Chen, Yueh-Yuan Tu, Jiang-Shiou Hwang, Wen-Tseng Lo

Journal of Marine Science and Technology

From 2000 to 2003, water samples were seasonally collected from the coastal area near nuclear power plants (NPPs) I and II to assess the ecological impact of thermal effluent on the water quality. The water quality in the investigated area during the survey periods was as follows: pH, 7.87-8.40; dissolved oxygen, 3.61-7.11 mL/L; chlorophyll a, 0.07-1.9 µg/L; nitrite, 0.02-7.42 µM; nitrate, 0.3- 15.4 µM; phosphate, 0.02-1.48 µM; and silicate, 0.84-46.82 µM. The concentrations of nutrients in the spring and winter seasons were relatively higher than those in the summer and fall seasons. The concentrations of chlorophyll a showed the reverse …

Journal of Marine Science and Technology

Species composition of phytoplankton was monitored seasonally in the waters off the First and Second Nuclear Power plants (NPP1 and NPP2), north of Taiwan during 2001-2002. In total, 290 phytoplankton samples were collected and 265 taxa of phytoplankton were recorded. Chaetoceros compressus, Pseudo-nitzschia delicatissima, Skeletonema costatum, Thalassionema nitzschioides, and Lauderia annulata were the top five dominant species. Together they comprised 75% of the total phytoplankton cells. The species number and abundance of phytoplankton showed distinct seasonal, annual, and spatial changes, higher abundance in 2002 than 2001 and highest in August in both years and lowest in March in 2001 and …

Effect Of Thermal Discharges On The Fish Assemblages Of A Nuclear Power Plant In Northern Taiwan, Ching-Yi Chen, Kwang-Tsao Shao, Yueh-Yuan Tu

Journal of Marine Science and Technology

The purpose of this paper is to study whether the thermal plume can affect the fish assemblages in the waters around the outlet area of the Second Nuclear Power Plant located at Kuosheng, a coastline between Yehliu and Chinshan village, northern coast of Taiwan. Both experimental and control stations of underwater census for reef fishes and of drift net sampling for pelagic or demersal fishes above sandy bottom were monitored four times per year from March 2001 to September 2004. The results show that no significant dif-ferences were found between the fish assemblages of the thermal waters and normal ambient …

Marine Environmental Radioactivity Near Nuclear Power Plants In Northern Taiwan, Chih-An Huh, Chih-Chieh Su, Yueh-Yuan Tu, Kwang-Tsao Shao, Ching-Yi Chen, I-Jiunn Cheng

Journal of Marine Science and Technology

The levels and composition of environmental radioactivity at the outlets of nuclear power plants and nearby coastal environs in northern Taiwan have been investigated by gamma spectrometric analysis of seawater, algae, fish and sediment samples collected systematically in the past four years. The results show that anthropogenic radionuclides contribute very little to the total radioactivities in all types of samples. Samples from the outlet of the Second Nuclear Power Plant are more enriched in artificial nuclides, with average algae samples containing ~4 Bq/kg of 137Cs + 54Mn + 60Co (or 3.6% of the total activity) and average sediment samples containing …

Taxonomic Composition And Seasonal Distribution Of Copepod Assemblages From Waters Adjacent To Nuclear Power Plant I And Ii In Northern Taiwan, Jiang-Shiou Hwang, Yueh-Yuan Tu, Li-Chun Tseng, Lee-Shing Fang, Sami Souissi, Tien-Hsi Fang, Wen-Tseng Lo, Wen-Hung Twan, Shih-Hui Hsiao, Cheng-Han Wu, Shao-Hung Peng, Tsui-Ping Wei, Qing-Chao Chen

Journal of Marine Science and Technology

The nuclear power plants are very important and cheap electric power source for Taiwan. However, the Nuclear Power Plant I and II (NPP I and II) are located in the northern Taiwan where the most populations inhabit. Therefore, the impact of operation of nuclear power plants on the surrounding environment, particularly in the surrounding waters, has drawn great attention to the public of Taiwan. Here we reported the first analyses on a three-year period of monitoring copepod assemblages in the adjacent waters to the NPP I and II. The copepod assemblages in the vicinity waters of NPP I and II …

Nearshore Macrobenthic Communities Off Two Nuclear Power Plants In Northern Taiwan, I-Jiunn Cheng, Pou-Chung Ko, Shin-I Hu, Chien-Peng Hu, Trip-Ping Wei

Journal of Marine Science and Technology

The nearshore macrobenthic communities outside the Nuclear Power Plants I and II were monitored on a seasonal basis from winter, 2000 to summer, 2004. The animal and sediment were sampled by scuba diving. The macrobenthic assemblages, sediment characteristics and total organic content were analyzed. The macrobenthos assemblages in terms of species richness, density and biomass was determined. The mean grain size and sorting (i.e. inclusive graphic standard deviation) of sediment were also determined. The small-sized annelids and crustaceans were the dominant macrobenthos. A total of 96 species of macrobenthos was found in the sediment near the Nuclear Power Plant I. …

Temporal Changes In Fish Assemblage From The Impingement Data At The Second Nuclear Power Plant,Northern Taiwan, Yun-Chih Liao, Li-Shu Chen, Kwang-Tsao Shao, Yueh-Yuan Tu

Journal of Marine Science and Technology

The main purposes of this study are to find out the temporal fluctuation of marine fish community based on impingement data collected at the Second Nuclear Power Plant in recent years (September 2000 to May 2004), and to compare the recent fish community structure data to that of an earlier period, around 14 years ago (July 1987 to April 1990). Comparison of the data collected recently to that collected 14 years ago showed that there were no yearly or monthly differences. However, the community structures reflected by clustering dendrograms or MDS ordination plots were quite different between earlier and recent …
