Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

Creator:: Coblentz, Kyle E.
Abstract:: Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

Marine Mass Mortality in a Global Change Context: Impacts on Individuals, Populations and Communities

Creator:: Sullivan Stack, Jenna
Abstract:: Human actions are pushing natural systems into states that have no historical precedent. In response, empirical and theoretical researchers are increasingly focused on developing ways to predict the responses of ecological systems to change. However, significant knowledge gaps remain, often leading to “ecological surprises” where observed impacts of global change...

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,...

Stage-structured interactions and their consequences across levels of biological organization

Creator:: Segui, Leah Mupas
Abstract:: A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...

The interactive effects of excess reactive nitrogen and climate change on aquatic ecosystems and water resources of the United States

Creator:: Baron, J. S., Hall, E. K., Nolan, B. T., Finlay, J. C., Bernhardt, E. S., Harrison, J. A., Chan, F., and Boyer, E. W.
Abstract:: Nearly all freshwaters and coastal zones of the US are degraded from inputs of excess reactive nitrogen (Nr), sources of which are runoff, atmospheric N deposition, and imported food and feed. Some major adverse effects include harmful algal blooms, hypoxia of fresh and coastal waters, ocean acidification, long-term harm to...

Predictability and constraints on the structure of ecological communities in the context of climate change

Creator:: Barner, Allison K.
Abstract:: Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...

The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

Explorations Into Who is Doing Freshwater Science and How We are Altering Waterscapes

Creator:: Abernethy, Erin F.
Abstract:: The United States of America and the world are faced with three massive intertwining challenges at this time: COVID-19, racial inequity, and climate change. As a species, humans must come together and collectively address these challenges to preserve our humanity and make our world a more just and livable place...

Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

Creator:: Cerny-Chipman, Elizabeth B.
Abstract:: The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

Thermal Tolerance and Adaptation in Cnidarians: An Investigation of Host Transcriptomic Responses and Heritable Variation Across Natural Populations

Creator:: Dziedzic, Katherine E.
Abstract:: Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...
