New Species In The Genus Monoecocesuts (Cestoda: Anoplocephalidae) From Neotropical Rodents (Caviidae And Sigmodontidae), Terry Haverkost, Scott Lyell Gardner 2010 University of Nebraska - Lincoln

New Species In The Genus Monoecocesuts (Cestoda: Anoplocephalidae) From Neotropical Rodents (Caviidae And Sigmodontidae), Terry Haverkost, Scott Lyell Gardner

Scott Gardner Publications & Papers

Anoplocephalid cestodes have a worldwide distribution, but relatively few species are known from South American rodents. By examining the collections of the Harold W. Manter Laboratory of Parasitology and the United States National Parasite Collection, 6 new species of Monoecocestus Beddard, 1914, are described, along with a redescription of Monoecocestus mackiewiczi Schmidt and Martin, 1978, based on the type specimens. The discussion includes commentary about uterine development, an important taxonomic character of the family, the vaginal dilation in immature segments (a character of potential taxonomic importance), and the implication of host usage to the evolutionary history and biogeography of species ...

The Fungal Connection: Characterizing The Ectomycorrhizal Community And Belowground Response To Restoration Treatments In Northern Mississippi., Ashley Jane Craig 2010 University of Mississippi

The Fungal Connection: Characterizing The Ectomycorrhizal Community And Belowground Response To Restoration Treatments In Northern Mississippi., Ashley Jane Craig

Electronic Theses and Dissertations

Ectomycorrhizal (ECM) fungi are symbionts on the roots of woody plant species throughout the world. These fungi provide plants with nutrients and are important drivers of ecosystem processes. ECM fungi vary in their effect on host plants and host-specificity, making them important considerations in restoration projects seeking to restore target tree species. Restoration strategies such as burning and thinning may have strong impacts on ECM fungi, and given the that ECM are important in structuring aboveground communities and maintaining certain dominant plant taxa, knowledge of ECM fungal response is needed to ensure restoration efforts succeed. Using molecular methods, this research ...


The Effects Of Ecological Restoration On Soil Microbial Enzyme Activities And Leaf Litter Decomposition, Anthony Jason Rietl 2010 University of Mississippi

The Effects Of Ecological Restoration On Soil Microbial Enzyme Activities And Leaf Litter Decomposition, Anthony Jason Rietl

Electronic Theses and Dissertations

This study examined the immediate effects of ecological restoration on soil enzyme activities and decomposition. The activities of five enzymes: phosphatase, ?-glucosidase, ?-N-acetylglucosadminidase (NAGase), phenol oxidase, and lignin-peroxidase were measured in both soils and on decomposing Quercus falcata leaf litter in unburned, burned, and burned and thinned plots in a mesic forest in northern Mississippi. Rates of decomposition were also assessed for Q. falcata leaf litter at each plot. The restoration treatments decreased phosphatase activity in relation to an increase in soil organic matter after the fire, and increased NAGase activity in relation to a decrease in leaf litter after ...


The Evolution Of Chloroplast Genome Structure In Ferns, Paul G. Wolf, J. M. Roper, A. M. Duffy 2010 Utah State University

The Evolution Of Chloroplast Genome Structure In Ferns, Paul G. Wolf, J. M. Roper, A. M. Duffy

Biology Faculty Publications

The plastid genome (plastome) is a rich source of phylogenetic and other comparative data in plants. Most land plants possess a plastome of similar structure. However, in a major group of plants, the ferns, a unique plastome structure has evolved. The gene order in ferns has been explained by a series of genomic inversions relative to the plastome organization of seed plants. Here, we examine for the first time the structure of the plastome across fern phylogeny. We used a PCR-based strategy to map and partially sequence plastomes. We found that a pair of partially overlapping inversions in the region ...


Microbial Community Characterization And Pathogen Analysis Within Constructed Wetlands Of Varying Scale Designed For Contaminant Removal, Michael R. Mitzel 2010 Wilfrid Laurier University

Microbial Community Characterization And Pathogen Analysis Within Constructed Wetlands Of Varying Scale Designed For Contaminant Removal, Michael R. Mitzel

Theses and Dissertations (Comprehensive)

Constructed wetlands (CWs) are complex treatment environments, requiring an integrative research approach to improve our understanding of them. The goal of this thesis was to establish an understanding of the functional and structural characteristics of microbial communities within bench-, field- and industrial-scale environmental treatment systems. The impact of pathogenic and/or antibiotic contaminants on these communities based on their functional and structural profiles using community-level physiological profiling (CLPP) and denaturing-gradient gel electrophoresis (DGGE), respectively, was investigated. Under normal operation, bench-, field- and industrial-scale treatment systems were able to produce similarly behaving structural and functional profiles. Increased retention time was consistently ...

Actions Of Ncx, Pmca And Serca On Short-Term Facilitation And Maintenance Of Transmission In Nerve Terminals, Mohati Desai-Shah, Robin L. Cooper 2010 University of Kentucky

Actions Of Ncx, Pmca And Serca On Short-Term Facilitation And Maintenance Of Transmission In Nerve Terminals, Mohati Desai-Shah, Robin L. Cooper

Biology Faculty Publications

Residual Ca2+ can accumulate in the nerve terminal during repetitive stimulation; thus, the basis for short-term facilitation (STF). The plasmalemmal Na+/Ca2+ exchanger [NCX], the Ca2+-ATPase (PMCA) and the sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA) on the endoplasmic reticulum are three important Ca2+ regulatory processes in controlling [Ca2+]i. The role of these [Ca2+]i regulators in the development and maintenance of STF was addressed at the neuromuscular junction. When the NCX is compromised by reduced [Na+]o, the EPSP amplitudes decrease, but with KB-R7943 (a reverse blocker of NCX) the amplitude ...


Roles Of The Sarcoplasmic/Endoplasmic Reticulum Ca2+-Atpase, Plasma Membrane Ca2+-Atpase And Na+/Ca2+ Exchanger In Regulation Of Heart Rate In Larval Drosophila, Mohati Desai-Shah, A. R. Papoy, M. Ward, Robin L. Cooper 2010 University of Kentucky

Roles Of The Sarcoplasmic/Endoplasmic Reticulum Ca2+-Atpase, Plasma Membrane Ca2+-Atpase And Na+/Ca2+ Exchanger In Regulation Of Heart Rate In Larval Drosophila, Mohati Desai-Shah, A. R. Papoy, M. Ward, Robin L. Cooper

Biology Faculty Publications

We investigated the roles of three regulatory proteins that impact [Ca2+]i within cardiac myocytes of Drosophila melanogaster. The NCX (Na+/Ca2+ exchanger), PMCA (plasma membrane Ca2+-ATPase) and SERCA (sarcoplasmic/endoplasmic reticulum Ca2+-ATPase) were compromised by ionic, pharmacological, mutationalmanipulation, and with a combination of approaches, while heart rate (HR) was monitored. A decrease in SERCA function reduced HR more for intact larva in comparison to a dissected larva. Dissected preparations were used to expose the heart directly to agents. A compromised PMCA also reduced HR; however, attenuated NCX function by low [Na+]○ increased HR ...

Effect Of Ingestion By Alligator Snapping Turtles (Macrochelys Temminckii) On Seeds Of Riparian Vegetation, Jean Pierre Elbers 2010 Missouri State University

Effect Of Ingestion By Alligator Snapping Turtles (Macrochelys Temminckii) On Seeds Of Riparian Vegetation, Jean Pierre Elbers

MSU Graduate Theses

The alligator snapping turtle (Macrochelys temminckii) is a large freshwater turtle that inhabits many lotic water bodies in the Southeastern United States. The species consumes primarily fish but also consumes large amounts of vegetation including seeds of common persimmon (Diospyros virginiana), tupelos (Nyssa sp.), willow oak (Quercus phellos), and pecan (Carya illinoensis). Captive specimens of M. temminckii were fed samples of the above-mentioned seeds to assess how the species affects ingested seeds in order to evaluate the potential role this species may play as a seed disperser. The proportion of seeds defecated intact varied with species (57−99 %), was lowest ...


Locomotion In Response To Shifting Climate Zones: Not So Fast, Martin E. Feder, Theodore Garland Jr., James H. Marden, Anthony J. Zera 2010 University of Chicago

Locomotion In Response To Shifting Climate Zones: Not So Fast, Martin E. Feder, Theodore Garland Jr., James H. Marden, Anthony J. Zera

Faculty Publications in the Biological Sciences

Although a species’ locomotor capacity is suggestive of its ability to escape global climate change, such a suggestion is not necessarily straightforward. Species vary substantially in locomotor capacity, both ontogenetically and within/among populations, and much of this variation has a genetic basis. Accordingly, locomotor capacity can and does evolve rapidly, as selection experiments demonstrate. Importantly, even though this evolution of locomotor capacity may be rapid enough to escape changing climate, genetic correlations among traits (often due to pleiotropy) are such that successful or rapid dispersers are often limited in colonization or reproductive ability, which may be viewed as a ...


Integrating Spatial And Temporal Approaches To Understanding Species Richness, Ethan P. White, S. K. Morgan Ernest, Peter B. Adler, Allen H. Hurlbert, S. Kathleen Lyons 2010 Utah State University

Integrating Spatial And Temporal Approaches To Understanding Species Richness, Ethan P. White, S. K. Morgan Ernest, Peter B. Adler, Allen H. Hurlbert, S. Kathleen Lyons

Faculty Publications in the Biological Sciences

Understanding species richness patterns represents one of the most fundamental problems in ecology. Most research in this area has focused on spatial gradients of species richness, with a smaller area of emphasis dedicated to understanding the temporal dynamics of richness. However, few attempts have been made to understand the linkages between the spatial and temporal patterns related to richness. Here, we argue that spatial and temporal richness patterns and the processes that drive them are inherently linked, and that our understanding of richness will be substantially improved by considering them simultaneously. The species–time–area relationship provides a case in ...


Behavior And Habitat Use Of Roseate Terns (Sterna Dougallii) Before And After Construction Of An Erosion Control Revetment, Corey Grinnell 2010 University of Massachusetts Amherst

Behavior And Habitat Use Of Roseate Terns (Sterna Dougallii) Before And After Construction Of An Erosion Control Revetment, Corey Grinnell

Masters Theses 1911 - February 2014

An erosion control revetment was constructed at the Falkner Island Unit of the Stewart B. McKinney National Wildlife Refuge, Connecticut during the winter of 2000–2001. At the time, Falkner Island was the fifth largest breeding colony site for the federally endangered Roseate Tern. This study measures and describes some baseline information regarding Roseate Tern nesting, behavior, and habitat use at Falkner Island during the three breeding seasons prior to revetment construction (1998–2000). This baseline information is then compared to similar information from the first breeding season following revetment construction (2001).

For Roseate Tern adults, this study examined changes ...
