Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This report provides an overview of flea species and the corresponding hosts in Mongolia and Tuva during 1999-2003. The taxonomical development of this vector group of great medical importance covers more than a century of flea research in Mongolia, resulting in the current number of 162 species known from this area.

Influence Of Dietary Selenium Supplementation Form On Hepatic Transcriptome Profiles Of Maturing Beef Heifers, Zhi Zhang

Theses and Dissertations--Animal and Food Sciences

Our objective was to know how the hepatic transcriptome expression of growing beef (Angus-cross) heifers (0.5 kg gain/day) was affected by the feeding of different sources of dietary (3 mg/day) Se supplements: inorganic Se (ISe, sodium selenite), organic (OSe, Sel-Plex®), or a blend (1.5 mg:1.5 mg) of ISe:OSe (Mix), compared to the adequate but non-Se supplemented “Control”. The biopsied hepatic tissues of these four groups heifers collected at day 168 (when liver Se assimilation had stabilized) after supplements of Se, was subjected to the microarray analysis to assess Se treatment effects.

The results suggest that there were clear differences in …

The Effects Of Slow Release Urea On Nitrogen Metabolism In Cattle, Vaughn B. Holder

Theses and Dissertations--Animal and Food Sciences

The objective of this research was to investigate the effects of slow release urea on N metabolism in cattle. The ruminal behavior of Optigen®II and the effect of basal diet on the in situ degradability of urea and Optigen®II were evaluated. The effect of slow release urea and its interaction with degradable intake protein (DIP) level in the diet on N retention and excretion was evaluated utilizing 8 Holstein steers in a 4 x 4 Latin square experiment. In addition, the effect of slow release urea and DIP level on ruminal and systemic urea kinetics was evaluated using stable isotope …

A New Species Of Molinema (Nematoda: Onchocercidae) In Bolivian Rodents And Emended Description Of Litomosoides Esslingeri Bain, Petit, And Diagne, 1989, Juliana Notarnicola, F. Agustin Jimenez Ruiz, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report the distribution of 2 species of filarioid nematodes occurring in different hosts in the central region of South America. Molinema boliviensis n. sp. was recorded as a parasite of sigmodontine and echymyid rodents in Bolivia, and Litomosoides esslingeri was recorded in sigmodontine and ctenomyid rodents from Bolivia and Argentina. Molinema boliviensis n. sp. shares several similarities with other species reported in spiny rats; however, it can be easily differentiated by the presence of a flat anterior end, gradually tapering lappets and a tubercle present in posterior end, a short, uniform buccal capsule, an oval-shaped vagina vera, and a …

Four Events Of Host Switching In Aspidoderidae (Nematoda) Involve Convergent Lineages Of Mammals, F. Agustin Jimenez Ruiz, Scott Lyell Gardner, Graciela Teresa Navone

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The Great American Interchange resulted in the mixing of faunistic groups with different origins and evolutionary trajectories that underwent rapid diversification in North and South America. As a result, groups of animals of recent arrival converged into similar habits and formed ecological guilds with some of the endemics. We present a reconstruction of the evolutionary events in Aspidoderidae, a family of nematodes that infect mammals that are part of this interchange, i.e., dasypodids, opossums, and sigmodontine, geomyid, and hystricognath rodents. By treating hosts as discrete states of character and using parsimony and Bayesian inferences to optimize these traits into the …

A New Genus And A New Species Of Cladorchiidae (Digenea: Dadayiinae) From Podocnemis Expansa (Chelonia) Of The Neotropical Region, State Of Pará, Brazil, Marcelo Knoff, Daniel Rusk Brooks, Maria Cristina Mullins, Delir Corrêa Gomes

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of amphistome digenean from the stomach and intestine of Podocnemis expansa (Pelomedusidae), of the tropical rain forest, from the State of Pará, Brazil, is described and allocated to a new genus (Oriximinatrema noronhae). The new species is characterized by the presence of an esophageal bulb, an esophageal extension uncovered by an extension of the pharyngeal sacs, a well-developed cirrus sac, post-bifurcal genital sucker, a ventro-terminal acetabulum with an anterior lip, and medium-sized eggs. This is the first report of a Dadayiinae trematode infecting a reptilian host.

Assessment Of Diver Impact During The Spiny Lobster Sport Season, Florida Keys, Usa, Mark Lewis Hartman

USF Tampa Graduate Theses and Dissertations

The Spiny Lobster (Panulirus argus) fishery in Florida is closed during the spawning season (March-July) except for a two-day recreational `miniseason' for sport divers in July, several days prior to the opening of the commercial fishing season. In Monroe County, recreational fishers, who possess a valid Saltwater Fishing License with crawfish stamp, are allowed to harvest six lobsters per day, each with a minimum carapace length of 76.2 mm (3.0 inches). During these two days, approximately 50,000 people attempt to catch lobster, and the number of boats visiting the reef has been estimated to be up to 900 times higher …

Externally-Expressed Fluorescence Across Sexes, Life Stages, And Species Of Spiders, Erin Brandt

Dissertations and Theses

Although all spiders possess fluorophores in their hemolymph, the expression of external fluorescence is much more restricted. The purpose of this study was to evaluate differences in externally-expressed fluorescence between sexes, life stages, and species of spiders. To approach this question, we developed novel instrumentation to capture fluorescence with photographs of our specimens. We paired these fluorescence measurements with spectrometer measurements to attempt to determine the role that fluorescence plays in the overall coloration in spiders. The study was divided into four sections. First, we examined how fluorescence varies in sexes and life stages in Misumena vatia, an ambush predator …
