Foraging Strategy Plasticity In Fiordland Penguins (Eudyptes Pachyrhynchus): A Stable Isotope Approach, Jeffrey Wayne White Jan 2020

Foraging Strategy Plasticity In Fiordland Penguins (Eudyptes Pachyrhynchus): A Stable Isotope Approach, Jeffrey Wayne White

Theses, Dissertations and Capstones

Foraging ecology in the crested penguins (genus: Eudyptes) is an active area of research, with new techniques rapidly increasing our understanding of these charismatic species. The most common techniques to assess foraging ecology include stomach content analysis, fecal DNA analysis, stable isotope analysis, tracking, and video loggers. Here we review dietary research on all 8 taxa within the genus Eudyptes to identify gaps in our current knowledge. However, foraging studies that assess dietary segregation require a method for quickly and accurately sexing penguins in the field. Obvious sexual dimorphism in plumage is largely absent in penguins leaving behavioral cues …

Laboratory Investigation On The Effects Of Conductivity On The Sensitive Early Life Stages Of Fishes From The Appalachian Region, Logan Ryan Beach Jan 2020

Laboratory Investigation On The Effects Of Conductivity On The Sensitive Early Life Stages Of Fishes From The Appalachian Region, Logan Ryan Beach

Theses, Dissertations and Capstones

While it is known there is a link between land disturbance and elevations in ionic constituents in streams, the relationship between elevated conductivity and aquatic taxa impairment is harder to define. Multiple field studies demonstrating correlations between conductivity and fish or benthic macroinvertebrate communities have not described the mechanisms of impairment and impairment has not been demonstrated with traditional toxicity testing. In an effort to explore more sensitive sub-lethal endpoints for evaluation of instream effects of mining effluent, chronic toxicity testing was conducted on eggs and early life stages of trout species and the fathead minnow, utilizing a simulated mining …

The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley Jan 2020

The Effectiveness Of Long-Distance Translocation Of Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Allison Grace Kelley

Theses, Dissertations and Capstones

Translocations have the potential to aim conservation efforts as well as to reduce mortality caused by human activities. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDB) have a limited ability to adapt to habitat loss and fragmentation due to the species’ slow life history and minimal dispersal ability. Because they are a venomous species, they are viewed as nuisance animals and are often killed on sight. We translocated a cohort of EDBs to investigate the potential of using translocations as a conservation and mitigation tool for this species. In July 2018, we translocated twelve adult eastern diamondback rattlesnakes from Parris …

Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller Jan 2020

Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller

Theses, Dissertations and Capstones

The eastern diamondback rattlesnake (Crotalus adamanteus; EDB) is a species of conservation concern associated with the imperiled longleaf pine-grassland ecosystem. The longleaf pine ecosystem is characterized by an open canopy and rich ground cover. Researchers have speculated that the vegetation structure of salt marshes may serve as a surrogate habitat for longleaf pine savannas. Although these marshes have little topography, they provide a heterogeneous landscape with patches of mud flats, sandy hard marsh along upper tidal areas, and salt marsh hummocks throughout. I used radio telemetry to monitor free-ranging EDBs on a South Carolina sea island. The goal of my …

Southern Fox Squirrel (Sciurus Niger Niger) Foraging Behavior And Population Dynamics, John Huang Jan 2020

Southern Fox Squirrel (Sciurus Niger Niger) Foraging Behavior And Population Dynamics, John Huang

Theses, Dissertations and Capstones

The change in the interaction between southern fox squirrel (Sciurus niger niger) and eastern gray squirrels (Sciurus carolinensis) provided an opportunity to examine sublethal effects of predation as it relates to a species’ risk perception and habitat structure at two scales. The interactions allowed us to examine the evolutionary responses of the southern fox squirrel and eastern gray squirrel to predation risk reflective of their historically associated landscapes and habitat structures. Second, the succession of savanna woodlands into closed-canopy mixed forest provided an opportunity to assess the flexible behaviors of both species in response to changes …

Juenger, Eugene V. Shakirov

Biological Sciences Faculty Research

Telomeres cap the physical ends of eukaryotic chromosomes to ensure complete DNA replication and genome stability. Heritable natural variation in telomere length exists in yeast, mice, plants and humans at birth; however, major effect loci underlying such polymorphism remain elusive. Here, we employ quantitative trait locus (QTL) mapping and transgenic manipulations to identify genes controlling telomere length set point in a multi-parent Arabidopsis thaliana mapping population. We detect several QTL explaining 63.7% of the total telomere length variation in the Arabidopsis MAGIC population. Loss-of-function mutants of the NOP2A candidate gene located inside the largest effect QTL and of two other …

Identity Of The Central American Scorpion Centruroides Mahnerti Lourenço, 1983 (Scorpiones: Buthidae), Luis F. De Armas Nov 2019

Identity Of The Central American Scorpion Centruroides Mahnerti Lourenço, 1983 (Scorpiones: Buthidae), Luis F. De Armas

Euscorpius

The Central American scorpion Centruroides mahnerti Lourenço, 1983, was described on the basis of three female specimens (holotype and paratypes) from Momotombo Volcano, Nicaragua. Almost two decades later, it was synonymized under Centruroides koesteri Kraepelin, 1911 by Armas and Maes, without examination of the type specimen; but Teruel and Stockwell posteriorly argued that description and figures given for C. mahnerti are also similarly referable to juveniles of C. edwardsii (Gervais, 1843). Now, an evaluation of the holotype of C. mahnerti has definitively shown that it is a subadult female of C. koesteri. For the first time, photographs of the …

Using Molecular Diet Analysis To Inform Invasive Species Management: A Case Study Of Introduced Rats Consuming Endemic New Zealand Frogs, Bastian Egeter, Cailín Roe, Sara Peixoto, Pamela Puppo, Luke J. Easton, Joana Pinto, Phillip J. Bishop, Bruce C. Robertson

Biological Sciences Faculty Research

The decline of amphibians has been of international concern for more than two decades, and the global spread of introduced fauna is a major factor in this decline. Conservation management decisions to implement control of introduced fauna are often based on diet studies. One of the most common metrics to report in diet studies is Frequency of Occurrence (FO), but this can be difficult to interpret, as it does not include a temporal perspective. Here, we examine the potential for FO data derived from molecular diet analysis to inform invasive species management, using invasive ship rats (Rattus rattus) …
