Alleviating Human-Elephant Conflict Through Deterrent Fences And Environmental Monitoring In Southern Kenya, Sophia Carmen Corde
Alleviating Human-Elephant Conflict Through Deterrent Fences And Environmental Monitoring In Southern Kenya, Sophia Carmen Corde
Masters Theses & Specialist Projects
Human-wildlife conflict is present across the world. In areas where human settlements overlap with elephant habitats, human-elephant conflict can result from crop raiding events, compromising farmers’ food and economic security, and putting humans and elephants in danger through farmer retaliation. Elephants raid crops primarily at night, when detection by humans is lowest, and during the dry season, as crops are developing towards harvest and natural forage quality drops. People living in these areas facing HEC have developed mitigation strategies to lessen the impacts and move towards coexistence. As a team member on the Elephants and Sustainable Agriculture in Kenya project, …
Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
Mahurin Honors College Capstone Experience/Thesis Projects
Zooplankton are small aquatic animals that serve an important role in transferring energy from phytoplankton to higher trophic levels. The zooplankton community composition in Barren River Lake from 2008 and 2020 was compared. A field study was conducted to not only describe the seasonal population dynamics of zooplankton in Barren River Lake, but also to determine if an invasive zooplankton, Daphnia lumholtzi, was present. While D. lumholtzi was found throughout Barren River Lake in 2008, it was absent from both resampled sites in 2019 and 2020. This, along with erratic patterns of emergence in several other zooplankton species, indicates …
Tourism And African Elephant (Loxodonta Africana) Behavior In Zambezi National Park, Zimbabwe, Brigit Rooney
Tourism And African Elephant (Loxodonta Africana) Behavior In Zambezi National Park, Zimbabwe, Brigit Rooney
Masters Theses & Specialist Projects
As charismatic megafauna and a flagship species, African elephants (Loxodonta africana) are vital to the African tourist economy. Conversely, high levels of wildlife tourism can induce behavioral shifts that push desired animals into less frequented areas and disrupt natural behaviors. In order to examine this trade-off, tourism levels and African elephant behaviors were studied in Zambezi National Park (ZNP) near Victoria Falls, Zimbabwe. Over the course of 14 weeks, in-person observations and camera traps in ZNP were used to collect geographic, demographic, and behavioral data from elephant sightings. As a proxy for human presence, geo-locational data were collected for each …
Documenting Marine Mammal Behavior And Evaluating The Benefits And Consequences Of Viewing Marine Mammals In Southcentral Alaska, Lauren E. Mccaslin
Documenting Marine Mammal Behavior And Evaluating The Benefits And Consequences Of Viewing Marine Mammals In Southcentral Alaska, Lauren E. Mccaslin
Masters Theses & Specialist Projects
Marine mammals are in a precarious conservation position because of anthropogenic impacts and historic perceptions that they are a consumable commodity. In light of changing abiotic conditions, further evaluation is needed on the habitat use, behavior, and interactions among marine mammals. Conservation legislation has helped protect species, but the greatest ground swelling may be the advent of the commercial whale watching industry. The feeding grounds in Alaskan waters have made this area a prime tourism location, and these nutrient-rich waters have resulted in a confluence of marine mammal species, including the appealing and abundant humpback whale (Megaptera novaeangliae) that may …
Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), Kathryn C. Laslie
Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), Kathryn C. Laslie
Masters Theses & Specialist Projects
While substrate-borne vibrations are utilized by different reptile species, true conspecific communication via biotremors has not yet been demonstrated in reptiles. This study follows a preliminary report that the veiled chameleon (Chamaeleo calyptratus) could produce biotremors in communicative contexts. I tested chameleon behavioral sensitivity to vibrations by placing them on a dowel attached to a shaker emitting vibrations of 25, 50, 150, 300, and 600 Hz and then measured their changes in velocity before and after the stimulus. I then paired chameleons in various social contexts [anthropogenic disturbance (human disruption of animal); dominance (malemale; female-female C. calyptratus); courtship (male-female C. …
An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen
An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen
Masters Theses & Specialist Projects
Escalating human elephant conflict (HEC) continues to be a contributing factor
towards elephant decline, and crop raiding is the most common form of negative
human-elephant interactions. For communities that cannot reverse or prevent crop
raiding, it is necessary to contain HEC events through deterrent measures. Few
deterrent measures exist that combine practicality and affordability while also
preventing habituation by elephants. This project focused on comparing the efficacy of
deterrent methods to assess which was the most successful at preventing elephants
from entering crops in the farming community of Sasenyi, Kenya. In this paired-control
study, four deterrent methods were evaluated: acacia …
Examination Of Enrichment Using Space And Food For African Elephants At The Sdzsp, Charlotte Hacker, Lance Miller, Bruce A. Schulte
Examination Of Enrichment Using Space And Food For African Elephants At The Sdzsp, Charlotte Hacker, Lance Miller, Bruce A. Schulte
Biology Faculty Publications
Concern for elephant welfare in zoological facilities has prompted a number of exhibit and management modifications, including those involving enrichment. Knowledge of how these changes impact indicators of welfare, such as elephant movement and behaviour, is crucial for continued improvement of elephant husbandry and care. The present study used observations and GPS-collected data to determine the effects of available space and food presentation on the walking distance and behaviour of thirteen African elephants (Loxodonta africana), which had a dominance structure ascertained by animal care staff at the San Diego Zoo Safari Park (SDZSP). This facility has two exhibits of approximately …
Global Phylogeny Of The Water Penny Beetles Using Both Molecular And Morphological Evidence (Co, Mathew Vincent Wood
Global Phylogeny Of The Water Penny Beetles Using Both Molecular And Morphological Evidence (Co, Mathew Vincent Wood
Masters Theses & Specialist Projects
The Psephenidae is a family of freshwater beetles usually found in swift streams worldwide. Their unique disc shaped and flattened larvae have made this a group of interest for scientists for centuries. Morphologically, this family has been relatively well researched, and systematically the family is fairly well known and supported as monophyletic. One issue with Psephenidae, and with many other insect groups, is the lack of the molecular phylogenetic analyses to test morphology hypothesizes.
After successfully sequencing these two genes from species representing nearly all of the known genera, the data were analyzed using both Bayesian and parsimony methods. Analyses …
Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis
Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis
Masters Theses & Specialist Projects
Numerous causes have been implicated in contributing to amphibian population declines since the 1980's, with habitat modification, ultraviolet radiation (UV-B) and environmental contaminants (such as glyphosate-based herbicide) being among the most common. This study identifies the effects of a generic glyphosate-based herbicide (GLY- 4 Plus) on mortality, immune function, body condition, and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy (i.e. greater UV-B exposure) may confer fitness benefits. In …
Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin
Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin
Masters Theses & Specialist Projects
Habitat connectivity is important to maintain in order to prevent loss of genetic diversity, reduce inbreeding depression, and decrease extinction risk in threatened or endangered species. Here I present a landscape genetics study on marbled salamanders (Ambystoma opacum) in highly connected forested habitat at Mammoth Cave National Park. This investigation of gene flow among ponds within a mostly continuous landscape provides data that can be compared with patterns observed in more fragmented landscapes. These comparisons can provide a means of investigating the separate effects of structural and functional habitat connectivity on amphibian genetic population structure. Structural connectivity refers to the …
