Autumn Roost Selection By Male Hoary Bats (Lasiurus Cinereus) In Northern California, Danielle (Skye) Salganek
Autumn Roost Selection By Male Hoary Bats (Lasiurus Cinereus) In Northern California, Danielle (Skye) Salganek
Cal Poly Humboldt theses and projects
The hoary bat, Lasiurus cinereus, is a solitary bat that roosts in the foliage of trees throughout the western hemisphere. Roosts are subject to the ambient temperature of their surroundings, thus hoary bats undergo long-distance migrations between summer and winter ranges to avoid freezing temperatures. Habitat selection has been studied during the summer for maternal female hoary bats, but not during migration and winter. Autumn migration coincides with the hoary bat mating period and it has been proposed that male and female bats may rendezvous on migration paths. Individuals may select roosts in stopover locations that enhance fitness by providing …
Evolutionary Genetic Aspects Of Host Association In Generalist Ectoparasites, Benoit Talbot
Evolutionary Genetic Aspects Of Host Association In Generalist Ectoparasites, Benoit Talbot
Electronic Thesis and Dissertation Repository
Despite the use of the host for dispersal by most parasite species, the extremely loose relationship typical between highly mobile hosts and generalist ectoparasites may lead to very different gene flow patterns between the two, leading in turn to different spatial genetic structure, and potentially different demographic history. I examined how similar gene flow patterns are between Cimex adjunctus, a generalist ectoparasite of bats present throughout North America, and two of its key bat hosts. I first analyzed the continent-scale genetic structure and demographic history of C. adjunctus and compared it to that of two of its hosts, the …
Habitat Usage Of Tri-Colored Bats (Perimyotis Subflavus) In Western Kentucky And Tennessee Post-White Nose Syndrome, Katherine Schaefer
Habitat Usage Of Tri-Colored Bats (Perimyotis Subflavus) In Western Kentucky And Tennessee Post-White Nose Syndrome, Katherine Schaefer
Murray State Theses and Dissertations
The tri-colored bat (Perimyotis subflavus) has declined severely across its range since 2006 due to white nose syndrome, a fungal disease causing massive bat mortality in North America. My objective was to determine distinguishing characteristics of roost trees and habitat used by tri-colored bats so that the species’ needs can be considered in management plans. I mist-netted for tri-colored bats in western Kentucky and Tennessee during the summers of 2015 and 2016, and attached a radio transmitter to each captured adult bat. I tracked 15 bats to their day roosts and collected habitat data at 38 roost areas …
Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson
Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson
Theses and Dissertations--Animal and Food Sciences
Bat populations in the eastern United States are currently declining at unprecedented rates as a result of habitat loss, commercial wind energy development, and white-nose syndrome. Effective conservation of these declining populations requires knowledge of several aspects of summer and winter ecology, including daytime habitat use (day-roost selection and social behaviors), nocturnal habitat use (foraging habitat selection, prey selection, and prey abundance), and winter hibernation (torpor) patterns. This dissertation addresses these questions for Rafinesque’s big-eared bat (Corynorhinus rafinesquii), a species of conservation concern in the southeastern United States. Kentucky represents the northern edge of the range of Rafinesque’s …
