Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro
Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro
Theses and Dissertations
During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …
Analysis Of Temperature And Salinity Effects On Growth And Mortality Of Oysters (Crassostrea Virginica) In Louisiana, Troy Sehlinger
Analysis Of Temperature And Salinity Effects On Growth And Mortality Of Oysters (Crassostrea Virginica) In Louisiana, Troy Sehlinger
University of New Orleans Theses and Dissertations
Salinity (S) and temperature (T) control every facet of the eastern oyster (Crassostrea virginica) life cycle, principally reproduction, development, growth, and mortality. Previous studies conducted in in the Breton Sound (BR) and Barataria (BA) estuaries have reported differences in growth and mortality rates between the basins. In the present study, environmental conditions were synchronized to compare growth and mortality rates between basins at similar combinations of T and S. Results indicate that when T and S are the same (synchronized), seasonal oyster growth and mortality rates differ between BR and BA. Seasonal analyses revealed that as salinities increased …
