  Citation × Citation Citation Abstract Copy Title: Community assembly of benthic invertebrates on island-like marine hard substrata Author: Meyer, Kirstin Year: 2016 Most of the seafloor is soft sediment, so hard substrata are isolated and island-like. In this dissertation, I explore how species distribution patterns on isolated marine hard substrata resemble terrestrial island communities, drawing on classical island biogeography theory and assembly rules, and describe how benthic invertebrate communities assemble in these island-like habitats. Higher species richness occurred on larger substrata (dropstones and shipwrecks), paralleling terrestrial island communities. However, while larger islands have greater habitat diversity and primary productivity, marine hard substrata are simpler habitats. Greater elevation in the benthic boundary layer may expose fauna to faster current, higher food supply and larval flux. Substrata located closer together had more similar communities, another pattern that resembles terrestrial islands. Dropstone fauna had a clumped distribution, indicating that larvae may disperse among substrata located close together, resulting in similar communities. In Svalbard fjords, benthic megafaunal communities were significantly different between Arctic- and Atlantic-influenced fjords. Depth and temperature had the greatest influence, with the highest diversity occurring in cold Rijpfjorden and on the north Svalbard shelf. Recruitment in Svalbard fjords was spatially and temporally variable, with lower recruitment in Rijpfjorden than in Atlantic-influenced fjords and lower recruitment at greater depth. Most of the recruits in Svalbard fjords were fast-growing, poor-competitive opportunists. On shipwrecks, communities showed two mechanisms of colonization: mobile fauna with long-dispersing planktotrophic larvae, and encrusting fauna with lecithotrophic larvae. Encrusting species reproduce asexually to cover the wreck surface, and philopatry may build up dense populations, leading to uneven communities. On terrestrial islands, non-random co-occurrence is attributed to interspecific competition, but for marine substrata, there may not be a relationship. Fauna were distributed randomly on settlement plates in Svalbard fjords, even when interspecific competition was observed. On dropstones, some morphotypes co-occurred non-randomly in the absence of overgrowth competition. Non-random co-occurrence on isolated marine hard substrata may be a result of restricted larval dispersal (for pairs co-occurring less than by chance) or epibiontism (for pairs co-occurring more often than by chance). While species distribution patterns on island-like marine hard substrata resemble terrestrial islands, the mechanisms are not necessarily the same.

  Citation × Citation Citation Abstract Copy Title: THE ORIGINS AND MAINTENANCE OF GENOMIC VARIATION IN THE THREESPINE STICKLEBACK (Gasterosteus aculeatus) Author: Nelson, Thomas Year: 2017 Genetic variation is the raw material of evolution. The sources of this variation within a population, and its maintenance within a species, have been mysterious since the birth of the field of evolutionary genetics. In this work, I study divergently adapted freshwater and marine populations of the threespine stickleback (Gasterosteus aculeatus) as an evolutionary model to track the origin of adaptive genetic variation and to describe the evolutionary processes maintaining variation across the genome. The stickleback is a small fish with a large geographic range encompassing the northern half of the Northern Hemisphere and composed of coastal marine habitats, freshwater lakes, and river systems. Populations of stickleback adapt rapidly to changes in habitat, and fossil evidence suggests that similar adaptive transitions have been ongoing in this lineage for at least ten million years. In this work, I develop a significant extension of restriction site-associated DNA sequencing (RAD-seq) to generate phased haplotype information to estimate gene tree topologies and divergence times at thousands of loci simultaneously. I find anciently derived clades of variation associated with marine and freshwater habitats in genomic regions involved in recent adaptive divergence; some divergence times extend to over ten million years ago. This history of adaptive divergence has had profound effects on genetic variation elsewhere in the genome: chromosomes harboring freshwater-adaptive variants retain anciently derived variation in linked genomic regions, while marine chromosomes have much more recent ancestry. I present a conceptual model of asymmetric selective and demographic processes to explain this result, which will form a nucleus for future research in this species. Lastly, by incorporating genome-wide recombination rates estimated from multiple genetic maps, I describe a recombination landscape that is favorable to the maintenance of marine-freshwater genomic divergence. Low recombination rates in key chromosomal regions condense widespread divergence of the physical genome, encompassing many megabases, into a small number of Mendelian loci. Combined, my results demonstrate the interconnectedness of evolutionary processes taking place on ecological and geological timescales. The genetic variation available for adaptive evolution today is a product of the long-term evolutionary history of a species.

  Citation × Citation Citation Abstract Copy Title: The Impact of Hypoxia on the Louisiana Brown Shrimp Fishery and the Potential for the Public Trust Doctrine to Slow Nonpoint Source Pollution Author: Rommwatt, Maya Year: 2015 Seasonal hypoxia in the northern Gulf of Mexico has been mapped extensively and is known to overlap the habitat of the brown shrimp Farfantepenaeus aztecus on the Louisiana continental shelf. Yet the impacts of Gulf hypoxia on the profitable brown shrimp fishery in Louisiana remain largely unknown. The problem is primarily attributable to nonpoint source pollution in the Mississippi River, but awareness of the problem has not resulted in an effective policy solution to stem this pollution to date. Using the combination of a quantitative data analysis to look for a correlation between Farfantepenaeus aztecus and hypoxic water, a survey mailed to shrimp fishers in Louisiana, and qualitative interviews with shrimp fishers and environmental activists and lawyers in Louisiana, I will examine the potential of a legal tool, the Public Trust doctrine, to slow nonpoint source pollution into the Mississippi River.

  Citation × Citation Citation Abstract Copy Title: An Agent-Based Model of Wildlife Migratory Patterns in Human-Disturbed Landscapes Author: Tierney, Lauren Year: 2015 In recent years, human decision-making has led to significant landscape impacts in the western United States. Specifically, migratory wildlife populations have increasingly been impacted by rural urban development and energy resource development. This research presents the application of agent-based modeling to explore how such impacts influence the characteristics of migratory animal movement, focusing on mule deer (Odocoileus hemionus) in Western Wyoming. This study utilizes complex adaptive systems and agent-based modeling frameworks to increase understanding of migratory patterns in a changing landscape and explores thresholds of interference to migration patterns due to increased habitat degradation and fragmentation. The agent-based model utilizes GPS-collar data to examine how individual processes lead to population-level patterns of movement and adaptation. The assessment incorporates elements from both human and natural systems to explore potential future scenarios for human development in the natural landscape and incorporates adaptive behaviors, as well as animal-movement ecology, in changing landscapes.
