Piping Plover (Charadrius Melodius) Conservation On The Barrier Islands Of New York: Habitat Quality And Implications In A Changing Climate, Jennifer Ruth Seavey
Piping Plover (Charadrius Melodius) Conservation On The Barrier Islands Of New York: Habitat Quality And Implications In A Changing Climate, Jennifer Ruth Seavey
Open Access Dissertations
Habitat loss is the leading cause of species extinction. Protecting and managing habitat quality is vital to an organism's persistence, and essential to endangered species recovery. We conducted an investigation of habitat quality and potential impacts from climate change to piping plovers (Charadrius melodius) breeding on the barrier island ecosystem of New York, during 2003-2005. Our first step in this analysis was to examined the relationship between two common measures of habitat quality: density and productivity (Chapter 1). We used both central and limiting tendency data analysis to find that density significantly limited productivity across many spatial scales, especially broader …
The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers
The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers
All Dissertations
Wastewater effluents have been shown to contain a variety of anthropogenic compounds, many of which have endocrine-disrupting properties. While multiple laboratory studies have shown the effects of such compounds on an individual basis at elevated concentrations, little research has attempted to characterize the effects of exposure to environmentally relevant mixtures of endocrine disruptors. The current study examined the effects of long-term exposure to graded concentrations of wastewater effluent on the fathead minnow, Pimephales promelas, and the northern leopard frog, Rana pipiens. Fathead minnows were exposed from the larval stage through sexual maturity, while northern leopard frogs were exposed as eggs …
Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad
Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad
Open Access Theses & Dissertations
Previous studies have demonstrated that the behavioral effects of nicotine withdrawal are lower in adolescent versus adult rats. However, the neurochemical mechanisms that mediate these developmental differences are presently unclear. Much work has shown that nicotine reward is mediated via enhanced dopamine neurotransmission in the mesolimbic pathway which originates in the ventral tegmental area (VTA) and terminates in several forebrain structures including the nucleus accumbens (NAcc). More recently, studies have shown that nicotine withdrawal produces a decrease in NAcc dopamine transmission, an effect that is believed to serve as a neurochemical marker of withdrawal in adult rodents. The goal of …
Hedging To Safety: A Political Economy Of Derivatives, Risk And Agriculture In The Developing World, Sasha Coler Breger Bush
Hedging To Safety: A Political Economy Of Derivatives, Risk And Agriculture In The Developing World, Sasha Coler Breger Bush
Electronic Theses and Dissertations
It has become common for researchers and international development institutions to recommend the use of derivative instruments to developing country farmers and policymakers as a means of insuring agricultural incomes against the threats posed by volatile global commodity prices. Despite such enthusiasm, very little research to date examines whether or not derivative instruments actually can deliver income support to agricultural producers who face commodity price risk. This dissertation evaluates these recommendations, focusing upon the potential income security benefits of hedging with futures instruments for coffee farmers in Mexico, Brazil and Uganda during the 1998-2002 coffee crisis. The three-part quantitative and …
