Habitat Selection By Two K-Selected Species: An Application To Bison And Sage Grouse, Joshua Taft Kaze
Habitat Selection By Two K-Selected Species: An Application To Bison And Sage Grouse, Joshua Taft Kaze
Theses and Dissertations
Population growth for species with long lifespans and low reproductive rates (i.e., K-selected species) is influenced primarily by both survival of adult females and survival of young. Because survival of adults and young is influenced by habitat quality and resource availability, it is important for managers to understand factors that influence habitat selection during the period of reproduction. My thesis contains two chapters addressing this issue for K-selected species in Utah. Chapter one evaluates habitat selection of greater sage-grouse (Centrocercusurophasianus) on Diamond Mountain during the critical nesting and brood-rearing period. Chapter two address selection of birth sites by bison (Bison …
Habitat Selection And Nesting Ecology Of Snowy Plover In The Great Basin, Kristen Sue Ellis
Habitat Selection And Nesting Ecology Of Snowy Plover In The Great Basin, Kristen Sue Ellis
Theses and Dissertations
Snowy plovers (Charadrius nivosus) are small, ground-nesting shorebirds that are a species of conservation concern throughout North America. Despite increased efforts to understand factors contributing to the decline of snowy plover, little is known about habitat selection and breeding ecology of snowy plover for the large population found in the Great Basin. We tested hypotheses concerning the occupancy and nesting success of snowy plover. First, we identified factors influencing snowy plover nest survival at Great Salt Lake, Utah. We hypothesized that snowy plover would demonstrate differences in nest survival rates across years due to differences in habitat characteristics, predator abundance, …
