Summer Foraging Range And Diurnal Roost Selection Of Tri-Colored Bats, Perimyotis Subflavus., Dustin Bradley Thames
Summer Foraging Range And Diurnal Roost Selection Of Tri-Colored Bats, Perimyotis Subflavus., Dustin Bradley Thames
Masters Theses
Tri-colored bat populations are declining in eastern North America where the fungal pathogen Pseudogymnoascus destructans has been introduced. The pathogen causes disease and mortality in cave hibernating bats. Once considered a common species in Tennessee, tri-colored bats are now being considered for protection under the Endangered Species Act. There is a paucity of research examining the basic ecology of tri-colored bats. Research to fill these knowledge gaps is needed to inform conservation plans and to define critical habitat. The first objective of my research was to characterize the summer diurnal roosts of tri-colored bats and to examine roost selection at …
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson
All HCAS Student Capstones, Theses, and Dissertations
Wildlife tourism is increasing in popularity around the world, creating the need to understand alterations in animal behavior and spatial distributions that may occur due to associated anthropogenic disturbances. Nurse sharks (Ginglymostoma cirratum, Bonnaterre 1788) are commonly used for wildlife tourism within the Caye Caulker Marine Reserve in Belize. Shark and Ray Village (SRV) is a site within the reserve where nurse sharks are consistently fed by tour/snorkel boats to create an interactive experience with tourists, termed provisioning tourism. Prior to this experiment, no studies had been conducted in SRV to evaluate the impact of provisioning tourism (tourism …
Population Status, Threats, And Conservation Of Preuss's Red Colobus (Piliocolobus Preussi) And Other Diurnal Primates In The Ndokbou Forest, Littoral Region, Cameroon, Ruth Bowers-Sword
Population Status, Threats, And Conservation Of Preuss's Red Colobus (Piliocolobus Preussi) And Other Diurnal Primates In The Ndokbou Forest, Littoral Region, Cameroon, Ruth Bowers-Sword
Masters Theses, 2020-current
The Ebo-Makombe-Ndokbou forest block in southwest Cameroon lies within the Gulf of Guinea biodiversity hotspot, characterized by extremely high levels of species richness and endemism, including those of primates. These forests may contain one of the last populations of the Critically Endangered Preuss’s red colobus monkey (Piliocolobus preussi; PRC), which is found only in southeastern Nigeria and western Cameroon. Gun hunting for bushmeat and habitat loss and degradation from logging and agriculture are the main threats to PRC. The conservation status of PRC and other primates in the Ndokbou forest are largely unknown, with most regional research efforts occurring in …
Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Electronic Theses and Dissertations
Mountain Sucker, Pantosteus jordani, is a cold-water species native to the Intermountain West. Fringe populations of Mountain Sucker have experienced declines in recent decades. The population of Mountain Sucker found in the Black Hills of South Dakota represents the eastern fringe of the species’ native range. Recognized as both an indicator of biologic health and as a species of greatest conservation need in South Dakota, recent studies have suggested significant declines in both distribution and abundance. Despite the recent study of Mountain Sucker in the region, increased understanding of Mountain Sucker ecology is needed to effectively manage for the conservation …
Conservation Grazing With Native Irish Cattle In High Nature Value Environments, Kilian Kelly
Conservation Grazing With Native Irish Cattle In High Nature Value Environments, Kilian Kelly
Theses
Marrying conservation objectives with farming practices is a challenging necessity in the current era of anthropogenically-driven biodiversity loss. Upland habitats created by traditional farming are havens for wildlife but face multiple threats, including overgrazing and abandonment. Extensive cattle farming in the uplands has been mooted as a useful conservation measure, but Irish evidence supporting this approach is lacking. This thesis examines home range, habitat preferences and activity budgets for Dexter cattle in an extensive upland setting in southwest Ireland. It investigates the effects of the grazing regime on EU-protected habitats and ground beetles. Free-ranging cattle grazed the site over three …
