Using Maximum Entropy Species Distribution Modeling For Long-Term Conservation Planning Of Three Federally Listed Bats In North America, Mitchell L. Meyer
Using Maximum Entropy Species Distribution Modeling For Long-Term Conservation Planning Of Three Federally Listed Bats In North America, Mitchell L. Meyer
Master's Theses
We are currently in a sixth mass extinction event in which the extinction rate is higher than it has ever been. This mass extinction event is caused by human influence on the environment. Biodiversity is worth conserving because of its many uses to humans. Bats are a diverse group of mammals that humans rely on for pest control services. The gray bat, northern long-eared bat, and Indiana bat are on the Threatened and Endangered Species List and are in need of conservation. I built species distribution models using occurrence records, climate data, and Maximum entropy (MaxEnt) modeling technique. I predicted …
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 …
The Effect Of Climate Change On The Distributions Of Invasive Plants And Their Associated Biological Control Agents In North America, Caroline A. Curtis
The Effect Of Climate Change On The Distributions Of Invasive Plants And Their Associated Biological Control Agents In North America, Caroline A. Curtis
Master's Theses
Climate change has the potential to alter the size, shape, and location of species’ distributions. As a result, the interactions between species are also likely to be impacted as novel species encounter each other and historical community assemblages are broken apart. To quantify the impact of distributional changes as a result of climate change on interacting species, distribution maps were produced for three species of invasive plant and their associated biological control agent at three time periods: current, 2050, and 2080. For each of the future time periods, two distribution maps were created for each species, representing the minimum and …
Climate Change: Implications For Montane Mammals Of The Great Basin, Georgina Yvette Jacquez
Climate Change: Implications For Montane Mammals Of The Great Basin, Georgina Yvette Jacquez
Master's Theses
Climate change threatens biodiversity; in particular, species with narrow distributions and specific habitat requirements. The Great Basin provides an excellent model system to evaluate the effects of climate change on species with isolated distributions and specific habitat requirements. I have evaluated the McDonald and Brown (1992) model that examined the effects of climate change on montane mammals of the Great Basin based on its underlying assumptions and model predictions. I have modeled the distributions of twelve montane mammal species found in the Great Basin and identified potential local extinctions by using maximum entropy modeling (Maxent) for two emission scenarios of …
