Historical Demography And Dispersal Patterns In The Eastern Pipistrelle Bat (Perimyotis Subflavus), Alynn M. Martin
Historical Demography And Dispersal Patterns In The Eastern Pipistrelle Bat (Perimyotis Subflavus), Alynn M. Martin
Masters Theses
The recent emergence of threats to North American bat conservation has prompted increased population genetics research on high risk species. The eastern pipistrelle bat is affected by both white-nose syndrome and wind turbine mortality. However, little work has been done regarding the population structure and effective population size of this species. Using the HVI region of the mitochondria and eight microsatellite loci, I analyzed male and female structure across the sample range of P. subflavus and estimated the effective population size of their populations. Pairwise FST values indicate that there is one panmictic population based on microsatellite data, while …
Regional Assessment Of The Relationships Of Conservation Practices To Northern Bobwhite And Other Priority Grassland Bird Breeding Populations, Christopher Manuel Lituma
Regional Assessment Of The Relationships Of Conservation Practices To Northern Bobwhite And Other Priority Grassland Bird Breeding Populations, Christopher Manuel Lituma
Doctoral Dissertations
I documented populations of Northern Bobwhites (Colinus virginianus) and other priority grassland and early successional birds in the Central Hardwoods Bird Conservation Region (CHBCR), and determined whether conservation practices have been effective in positively impacting species occupancy and abundance. I designed and implemented a roadside survey by randomly locating five 15-km routes with 5-min unlimited distance point counts (30 counts/route), along secondary roads within Northern Bobwhite focal counties (n = 37) in the CHBCR. I also developed a survey to assess roadside biases for estimates of relative abundance (a), occupancy (ψ), detection probability (p), and associated …
Inferring Herpetofaunal Distributions And Habitat Preferences For Conservation Planning, Lisa M. Prowant
Inferring Herpetofaunal Distributions And Habitat Preferences For Conservation Planning, Lisa M. Prowant
Master's Theses
Global climate change is a serious threat to global biodiversity (IPCC, 2001). Due to their limited dispersal ability, reptiles and amphibians might be more vulnerable to rapid climate change than are other taxonomic groups (Gibbons et al., 2000). Herpetofauna in south-central Kansas was sampled from May through August in 2012 and 2013. Seven study sites spanning Meade, Clark, Comanche, and Barber counties were sampled. Drift fence and cover-board traps were arranged in transects at each site to capture reptiles and amphibians. Species were also sampled through surveys on all-terrain vehicles and on foot. Two thousand nine hundred and forty five …
Conspecific Attraction In A Low-Density Population Of A Threatened Songbird, Daniel James Albrecht-Mallinger
Conspecific Attraction In A Low-Density Population Of A Threatened Songbird, Daniel James Albrecht-Mallinger
Theses and Dissertations
Many organisms use both vegetation structure and social cues in selecting habitats. Many species of songbirds use the presence of breeding conspecifics as a social cue and sign of habitat quality, and can be induced to settle in unoccupied habitats by artificially broadcasting breeding song, a process referred to as “conspecific attraction”. In our study, we tested response to conspecific attraction a low-density population of the threatened Golden-winged Warbler (Vermivora chrysoptera) in Highland County, VA. Response to broadcast song was observed, with a modest increase in mean male abundance at survey points within 250 meters of treatments, and mean abundance …
