Seasonal Ecology Of Mottled Sculpin And Brown Trout In A Coldwater Michigan Stream, Susanna K. Lagory
Masters Theses
In temperate regions, environmental conditions vary distinctly between seasons. This variation can strongly impact in-stream environmental conditions. Winter is often thought to be harsher than other seasons for stream fishes, given the adverse environmental conditions that arise from low temperatures during winter in temperate regions. Low temperatures, episodic elevated discharge, and ice formation associated with winter are hypothesized to reduce movement, body condition, and survival of stream fishes. However, few studies test this hypothesis through formal comparisons, and most studies of seasonal stream fish ecology focus on salmonids. To address this knowledge gap, I estimated and compared body condition, net …
Nest-Site Selection And Neonate Survival Of Eastern Box Turtles (Terrapene Carolina Carolina) In Michigan’S Northern Lower Peninsula, Joseph T. Altobelli
Nest-Site Selection And Neonate Survival Of Eastern Box Turtles (Terrapene Carolina Carolina) In Michigan’S Northern Lower Peninsula, Joseph T. Altobelli
Masters Theses
Turtles (Order Testudines) are experiencing global declines largely due to anthropogenic influences such as habitat fragmentation, illegal collection and sales, and the threat of global climate change. Removal of individuals from the adult age-classes means there is now a greater need to understand the survival of neonate and juvenile turtle age-classes. In this study I examined a population of eastern box turtles (Terrapene carolina carolina) at the northern limit of their range in Michigan’s lower peninsula. The objectives of my thesis were 1. to determine the microhabitat factors that influence nestsite selection by female box turtles and how …
