Population Demography, Spatial Ecology, And Habitat Use Of The Florida Box Turtle (Terrapene Bauri) On A Barrier Island, Michael D. Mills 2022 University of South Florida

Population Demography, Spatial Ecology, And Habitat Use Of The Florida Box Turtle (Terrapene Bauri) On A Barrier Island, Michael D. Mills

USF Tampa Graduate Theses and Dissertations

Turtles are one the most threatened vertebrate groups in the world due to anthropogenic threats such as habitat loss and overexploitation. In addition to occupying a range that has been vulnerable to major habitat loss, the Florida box turtle (Terrapene bauri) is particularly at risk of overexploitation due to its popularity in the pet trade. Sanibel Island is a barrier island in southwest Florida that has experienced major habitat loss and is the site of a recent poaching event. In response to these threats, studies of both the population demography and spatial ecology were conducted on Sanibel’s Florida box turtle …

Oxidative Stress Strongly Restricts The Effect Of Codon Choice On The Efficiency Of Protein Synthesis In Escherichia Coli, Lorenzo Eugenio Leiva, Sara Elgamal, Sebastian A. Leidel, Omar Orellana, Michael Ibba, Assaf Katz

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Introduction

The response of enterobacteria to oxidative stress is usually considered to be regulated by transcription factors such as OxyR and SoxR. Nevertheless, several reports have shown that under oxidative stress the levels, modification and aminoacylation of tRNAs may be altered suggesting a role of codon bias in regulation of gene expression under this condition.

Methods

In order to characterize the effects of oxidative stress on translation elongation we constructed a library of 61 plasmids, each coding for the green fluorescent protein (GFP) translationally fused to a different set of four identical codons.

Results

Using these reporters, we observed that …

The Effects Of Floral And Social Information On Bumblebee Forager Learning And Memory, Avery Hume Baker 2022 University of Missouri-St. Louis

The Effects Of Floral And Social Information On Bumblebee Forager Learning And Memory, Avery Hume Baker

Theses

Bumblebees rely on information gathered from their environment to make the best choices they can when foraging for pollen and nectar. The type of information gathered should influence how a bee learns and remembers it, but other factors such as the size of the bee’s brain may also play a role in the learning and remembering process. While social information learned from other organisms and information gathered directly from flowers can each be used alone to improve both the efficiency with which a bee learns to forage from a flower and how accurately and how long the bee remembers these …


Internal Vertebral Morphology Of Bony Fishes Matches The Mechanical Demands Of Different Environments, Dana Baxter, Karly E. Cohen, Cassandra M. Donatelli, Eric D. Tytell 2022 Tufts University

Internal Vertebral Morphology Of Bony Fishes Matches The Mechanical Demands Of Different Environments, Dana Baxter, Karly E. Cohen, Cassandra M. Donatelli, Eric D. Tytell

Engineering Faculty Articles and Research

Fishes have repeatedly evolved characteristic body shapes depending on how close they live to the substrate. Pelagic fishes live in open water and typically have narrow, streamlined body shapes; benthic and demersal fishes live close to the substrate; and demersal fishes often have deeper bodies. These shape differences are often associated with behavioral differences: pelagic fishes swim nearly constantly, demersal fishes tend to maneuver near the substrate, and benthic fishes often lie in wait on the substrate. We hypothesized that these morphological and behavioral differences would be reflected in the mechanical properties of the body, and specifically in vertebral column …

Reproduction In Relation To Heavy-Metal Contamination Along An Urbanization Gradient In Aninvasive Florida Lizard Species (Anolis Sagrei), Elizabeth Hauck 2022 University of South Florida

Reproduction In Relation To Heavy-Metal Contamination Along An Urbanization Gradient In Aninvasive Florida Lizard Species (Anolis Sagrei), Elizabeth Hauck

USF Tampa Graduate Theses and Dissertations

Environmental contamination is accumulating rapidly worldwide due to increasing urbanization rates. Heavy metals are known to be particularly toxic to organisms, to accumulate in biological systems, and to be found in higher concentrations in animals located in areas of high urban levels. However, the physiological impacts of these toxic heavy metals in wildlife remain largely unknown. Lizards are excellent bioindicator species for environmental contaminants due to their trophic level as mesopredators and their susceptibility of exposure via air, water, diet, and soil through egg deposition. To assess the impacts heavy-metal contamination has on reproductive parameters in lizards and how these …

Cougars In The Eastern United States, Justina Raleva, Kenneth Rieche

Scholars Week

Since the 1900s, cougars have been extirpated from nearly everywhere except the western United States parks and wilderness areas. In recent years, cougars have been starting to spread their range outside of the Rocky Mountains, towards eastern states like Illinois, Missouri, and Louisiana. The purpose of this project is to conduct outreach and education through a brochure that would educate locals in Kentucky and Tennessee regarding cougar safety and conservation importance.

Title: Retrieve, Race, Release

by: Paige McCord, Karamello Young, Madison Morrison, Emily Fitzgerald

Abstract: This poster represents a service-learning project that was done for our conservation biology class. Our main goal is to educate the public about the negative impacts of turtle derbies. We did this by using educational materials to raise awareness about turtle races and the impact of painting them with toxic substances before releasing them into a habitat that is not their natural one. We did not seek out to prohibit or stop the races as that would cause people to shut down and not listen as …

The genomes of both phages are ~65,000 bp, with similar GC contents, and, based on gene content similarity to phages in the Actinobacteriophage Database, were assigned to phage cluster DV.


Zebras Of All Stripes Repel Biting Flies At Close Range, Kaia J. Tombak, Andrew S. Gersick, Lily V. Reisinger, Brenda Larison, Daniel I. Rubenstein 2022 CUNY Hunter College

Zebras Of All Stripes Repel Biting Flies At Close Range, Kaia J. Tombak, Andrew S. Gersick, Lily V. Reisinger, Brenda Larison, Daniel I. Rubenstein

Publications and Research

The best-supported hypothesis for why zebras have stripes is that stripes repel biting flies. While this effect is well-established, the mechanism behind it remains elusive. Myriad hypotheses have been suggested, but few experiments have helped narrow the field of possible explanations. In addition, the complex visual features of real zebra pelage and the natural range of stripe widths have been largely left out of experimental designs. In paired-choice field experiments in a Kenyan savannah, we found that hungry Stomoxys flies released in an enclosure strongly preferred to land on uniform tan impala pelts over striped zebra pelts but exhibited no …

Faculty Publications in the Biological Sciences

Animals’ space requirements may vary according to life-history and social considerations. We observed 516 wild adult Asian elephants from both sexes, over 9 years, to investigate how life-history traits and social behavior influence protected-area (PA) use at Udawalawe National Park, Sri Lanka. Male PA-use, quantified in terms of average between-sightings-interval (BSI), was significantly influenced by the interaction of age class and motivational state (i.e. reproduction vs. foraging). Musth lengthened with age, with a median of 24.5 days for ages 21–30, 32.5 days for ages 31–40, and 45 days for those > 40. A minority (11%) used it exclusively during musth, while …


Investigating Students' Interpretations Of Ecological Food Webs, Christopher Neil Grissett 2022 University of South Florida

Investigating Students' Interpretations Of Ecological Food Webs, Christopher Neil Grissett

USF Tampa Graduate Theses and Dissertations

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote biological literacy. One example of a system that students have difficulty understanding is an ecological food web, which consists of parts or components interacting with one another to perform a given phenomenon. The intricacies of this system tend to confuse students and can produce naïve conceptions that could hinder future learning …

Introducing Interdisciplinary Curricula Into Conservation Biology: Exploring Changes In Students’ Perceived Proenvironmental Attitudes And Behaviors, Jasmine Janes, Lindsay J. Mccunn

Journal of Educational Research and Practice

Today, conserving the natural environment is paramount. Educators have been striving to develop pedagogical approaches that facilitate greater engagement in conservation behaviors. However, many of these reforms have been targeted at an institutional level, without necessarily testing whether changes in proenvironmental perceptions, attitudes, or behaviors occur for students. This step seems important when developing conservation biology courses that provide well-rounded education that may better prepare students for future challenges in biodiverse conservation contexts. Our objective was to assess the proenvironmental attitudes and conservation values of undergraduate students enrolled in an undergraduate conservation biology course before and after instruction to determine …

Biology Faculty Publications and Presentations

We studied population density, population size, and reproductive seasonality of the Phantom Tryonia, Tryonia cheatumi (Pilsbry, 1935). This endangered freshwater snail is found only in the San Solomon Spring system, a cienega, or karst-based, arid-land freshwater spring system, in western Texas, USA. We sampled populations at seven locations in the system seasonally over a 2-yr period. San Solomon Spring, the system's largest spring and modified into a swimming pool, had the largest population of T. cheatumi, with an estimated 49 million individuals and a mean density as high as 23,626 ± 39,030 (individuals/m2 ± SD). There were seasonal differences …

Urban rivers often contain elevated concentrations of contaminants such as organic pollutants and heavy metals which can be amplified in lotic ecosystems receiving effluents from wastewater treatment plants (WWTP). However, the impact of WWTPs on the microbial parameters of the urban river sediments has not been well documented compared to urban surface water. Collecting sediment samples at five different locations over a 9,000 m transect during four sampling periods, we investigated spatiotemporal variations of microbial parameters in sediments of lower Des Plaines River; the largest effluent-dominated stream in the United States and the effects of sediment physicochemical properties on the …
