Phenotypic variation in the sexual attractiveness pheromone of the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: LeMaster, Michael P.
Abstract:: Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

Bioinformatics applied to freshwater cyanobacterial blooms and cyanophage

Creator:: Schwartz, Andrew D.
Abstract:: Freshwater cyanobacterial blooms are a nuisance and health threat in the Pacific Northwest. The accepted methods of characterizing these blooms by microscopic cell counts cannot differentiate between toxic and non-toxic strains of the cyanobacterium Microcystis. Also, there is limited understanding of freshwater cyanophage that may control bloom dynamics. In order...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Involvement of the Ets-1 transcription factor in early bovine and porcine embryo development

Creator:: Stauber, Leah
Abstract:: Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...

Reproductive biology and behavior of the brown tree snake (Boiga irregularis) on Guam.

Creator:: Waye, Heather L.
Abstract:: While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...

The effects of ad libitum feeding 7% crude protein diets with varying energy levels on the reproductive performance of caged broiler breeder males

Creator:: Rakphongphairoj, Vinai
Abstract:: The reproductive performance of four strains of broiler breeder males (BBM) were compared when housed in individual cages from 22 to 56 weeks of age (WOA), and fed Asi libitum 7% crude protein (CP) diets with 1985, 2424, 2868 kilocalories (kcal) metabolizable (M) energy (E) per kg of feed and...

Complexity of food web interactions in a large mammal system

Creator:: Eisenberg, Cristina
Abstract:: Food webs consist of a combination of bottom-up (resource-driven) and top-down (predator-driven) effects. The strength of these effects depends on the context in which they occur. I investigated food web (trophic) relationships between wolf (Canis lupus) predation, elk (Cervus elaphus) herbivory, aspen (Populus tremuloides Michaux) recruitment, and fire. The study...

Analysis of the international demand for Brazil nuts

Creator:: Paez, Paulo Brasil
Abstract:: The basic objective of this investigation was to identify and to examine factors determining the volume of imports of inshell and shelled Brazil nuts in major importing countries: the United States, the Federal Republic of Germany and the United Kingdom. The approach followed involved the construction and analysis of an...

A policy preference function analysis of the forest sector in the Cote d'Ivoire

Creator:: Yapi, Atse
Abstract:: The main objective of this study was to offer an alternative methodology for forest sector modeling in developing economies. To this effect, a policy preference function was developed and estimated using data from the forest sector of the Cote d'Ivoire. The justification for this alternative framework for forest sector analysis...
