Movement, Habitat Use And Detection Probability Of Bridle Shiner Estimated By Patch Occupancy Modeling In A Connecticut Watershed, Timothy Jensen

Master's Theses

The bridle shiner (Notropis bifrenatus) is believed to have once been an important prey item throughout its native range; however, recent reports suggest populations have declined significantly and the species is now widely considered as imperiled. Habitats that are associated with this species are typically difficult to sample using traditional methods, making it unclear how much of the observed range reduction could be actual or perceived. My objectives were to estimate detection probability of bridle shiner, evaluate the importance of habitat on their distribution, and determine patterns of movement among habitat patches. I employed a repeated surveys design …
