Scale and Pattern: Delineating the Effects of Local to Regional Processes and Species Identity in Producing Multi-scale Responses of Macroalgae

Creator:: Spiecker, Barbara J.
Abstract:: Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...

Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

Creator:: Kanda, Kojun
Abstract:: In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

Grow fast or die young: influence of ocean conditions and larval growth on patterns of selective mortality and settlement variability of rockfishes

Creator:: Fennie, Hamilton William
Abstract:: Most benthic marine fishes have a biphasic life cycle with a dispersive pelagic larval stage that spends weeks to months in the plankton before metamorphosing into juveniles and settling to benthic habitats. The magnitude of mortality during the early life stages of marine fishes typically drives variability in year-class strength....

Drivers of Kelp Forest Responses to Global Change: From Populations to Policies

Creator:: Hamilton, Sara L.
Abstract:: Kelps are large brown algae in the order Laminariales and are foundation species that form the basis of kelp forests. Present across a quarter of the world’s coastlines, kelp forests provide diverse services to coastal communities, as habitat for commercially and culturally important species, as a food source for humans...

Evolutionary Dynamics of Genomes and Endosymbionts in Plant-Parasitic Nematodes

Creator:: Wasala, Wasala Mudiyanselage Sulochana K.
Abstract:: Plant-parasitic nematodes cause more than US $100 billion in annual agriculture loss worldwide. Thorough knowledge of their genetic diversity, and interactions with endosymbionts and environment have the potential to provide valuable insights into the basic biology of these animals, and assist future efforts aimed at management of these plant parasites....

Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

Orbiting the Genus of False Units: Dynamics of Phage Genomes and Nematode Microbiomes Associated with Pseudomonas spp.

Creator:: Ha, Anh D.
Abstract:: Pseudomonas is a diverse, ubiquitous, and widely studied genus of bacteria. As Pseudomonas species occupy a wide range of niches in the ecosystem, they have made remarkable biological impacts. Better understanding of Pseudomonas biology, genetic diversity, and functional interactions with other organisms and the environment will provide valuable insights into...

Advances in Camelid Theriogenology

Creator:: McAllister, Anna
Abstract:: Reproductive physiology of South American camelids is unique, especially in comparison to other domestic animals. For example, mating occurs in a recumbent position over a period of approximately 30 minutes. Males are dribble ejaculators, and the camelid ejaculate is highly viscous making it nearly impossible to work with in vitro....

Morphology, Sediment Microbial Analysis, and Species Distribution Modeling of a New Offshore Population of Ghost Shrimp (Neotrypaea sp.)

Creator:: Hardisty, Sarah
Abstract:: In 2019, a multi-cohort population of the typically estuarine burrowing shrimp Neotrypaea sp., was discovered approximately 7 miles offshore of Newport, Oregon. Morphological analysis of the offshore population, microbial sediment sequencing, and species distribution modeling was conducted with this new offshore population. In order to identify Neotrypaea sp. to the...

Adaptive Potential of Coastal Invertebrates to Environmental Stressors and Climate Change

Creator:: Burton, Andrea R.
Abstract:: Climate change presents multiple stressors that are impacting marine life. As carbon dioxide emissions continue to increase in the atmosphere, atmospheric and sea water temperatures increase. In addition, more carbon dioxide is absorbed into the oceans, reducing pH and aragonite saturation state, resulting in ocean acidification (OA). Tightly coupled with...
