Diet Analysis Of Stranded Bottlenose Dolphins (Tursiops Truncatus) In Virginia, Kristen Marie Volker Apr 2020

Diet Analysis Of Stranded Bottlenose Dolphins (Tursiops Truncatus) In Virginia, Kristen Marie Volker

Biological Sciences Theses & Dissertations

This study describes the diet of bottlenose dolphins (Tursiops truncatus) stranded in Virginia via stomach content analysis and considers factors such as proportion of numerical abundance and reconstructed mass, frequency of occurrence, average reconstructed prey size, prey diversity and quantity, and otolith degradation code. Fish size was estimated via regression equations established from local fish collected during the study that derive wet weight directly from otolith length or width. Squid size is estimated from previously published equations. Soniferous fishes dominated the diet, especially Atlantic croaker, spot, and seatrout spp., adding evidence to the theory that bottlenose dolphins passively …


A Reexamination Of The Freshwater Mussel Community Of The Little Miami River, Emily Davis Apr 2020

A Reexamination Of The Freshwater Mussel Community Of The Little Miami River, Emily Davis

Undergraduate Honors Thesis Projects

Understanding the changes in biodiversity and local freshwater mussel populations is critical to mitigate the risks to these populations. Freshwater ecosystems continue to degrade rapidly. The freshwater mussel community of the Little Miami River is degraded and has been in decline for many years. The biodiversity contained within freshwater ecosystems is lost at unprecedented rates influenced by human activity. Freshwater mussels play a key role in understanding the effects of human activity on freshwater ecosystems as well as maintaining the health of freshwater habitats. However, they are also sensitive to changes and disturbances, in their ecosystems. This study involved monitoring …


The Role Of Dislodgement In The Territorial Ecology Of The Owl Limpet, Lottia Gigantea, Ryan T. Kabala, Natalie Swinford, Maria J. Mason, William G. Wright Feb 2020

The Role Of Dislodgement In The Territorial Ecology Of The Owl Limpet, Lottia Gigantea, Ryan T. Kabala, Natalie Swinford, Maria J. Mason, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Ascertaining the risks and benefits of different behaviors is a central goal of research on territoriality. Although most territorial behavior is ritualized, with concomitant reduced risks for both residents and intruders, this ritualization is generally found to be underpinned by rare, highly consequential, interactions. The agonistic behavior of the intertidal owl limpet, Lottia gigantea, involves defense of a feeding territory, and includes a relatively explosive thrusting response by territory holders against intruding conspecifics. We here ask whether this thrusting behavior is capable of entirely dislodging intruders from their rocky wave-swept substratum, thereby ridding the resident of future challenges by …


Host Population Genetics And Biogeography Structure The Microbiome Of The Sponge Cliona Delitrix, Cole Easson, Andia Chaves-Fonnegra, Robert W. Thacker, Jose Lopez Jan 2020

Host Population Genetics And Biogeography Structure The Microbiome Of The Sponge Cliona Delitrix, Cole Easson, Andia Chaves-Fonnegra, Robert W. Thacker, Jose Lopez

Biology Faculty Articles

Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological relationships between hosts and their symbiotic microbial communities remain to be fully delineated. In the current study, we investigate the relative roles of host population genetics and biogeography in structuring the microbial communities hosted by the excavating sponge Cliona delitrix. A total of 53 samples, previously used to demarcate the population genetic structure of C. delitrix, were selected from two locations in the Caribbean Sea and …
