A Deep Life: The Application Of Stable Isotopes To Understand Deep-Sea Environments With A Focus On Latitudinal Gradients, Laurissa Christie Jul 2020

A Deep Life: The Application Of Stable Isotopes To Understand Deep-Sea Environments With A Focus On Latitudinal Gradients, Laurissa Christie

Electronic Theses and Dissertations

The deep-sea, defined as the area 200 m below the surface, is facing emerging chemical, physical and biological stressors. Currently, very little is known regarding deep-sea ecosystems both globally and in the Arctic. In this thesis I undertook a literature review on the current understanding of global deep-sea ecosystems through the use of stable isotopes. Specifically, I synthesized the available literature on spatial variation, energy pathways, depth, temporal variation, feeding behaviour, niche, trophic position and body size isotopic trends. This thesis then presents a case study examining the isotopic niche of five teleost and two decapod species within Arctic deep-sea …


Integrating Agriculture And Ecosystems To Find Suitable Adaptations To Climate Change, Anastasia W. Thayer, Aurora M. Vargas, Adrian A. Castellanos, Charles W. Lafon, Bruce A. Mccarl, Daniel L. Roelke, Kirk O. Winemiller, Thomas E. Lacher Jan 2020

Climate change is altering agricultural production and ecosystems around the world. Future projections indicate that additional change is expected in the coming decades, forcing individuals and communities to respond and adapt. Current research efforts typically examine climate change effects and possible adaptations but fail to integrate agriculture and ecosystems. This failure to jointly consider these systems and associated externalities may underestimate climate change impacts or cause adaptation implementation surprises, such as causing adaptation status of some groups or ecosystems to be worsened. This work describes and motivates reasons why ecosystems and agriculture adaptation require an integrated analytical approach. Synthesis of …

Investigating The Effects Of Climate Co-Stressors On Surf Smelt Energy Demands, Megan Russell Jan 2020

Investigating The Effects Of Climate Co-Stressors On Surf Smelt Energy Demands, Megan Russell

WWU Graduate School Collection

Surf smelt (Hypomesus pretiosus) are ecologically and economically important to the Pacific Northwest. They play a critical role in the food web and support numerous commercially important species and are an economically important baitfish. Surf smelt interact closely with the nearshore environment, utilizing approximately 10% of Puget Sound coastlines for spawning throughout the year. Surf smelt spawn at high tide and adhere fertilized eggs to beach sediment, causing their embryos to be exposed to air and seawater throughout embryonic development. Because of this unique life history, surf smelt may be susceptible to anthropogenic stressors including coastal development and …


Transboundary Fisheries, Climate Change, And The Ecosystem Approach: Taking Stock Of The International Law And Policy Seascape, Cecilia Engler Jan 2020

Transboundary Fisheries, Climate Change, And The Ecosystem Approach: Taking Stock Of The International Law And Policy Seascape, Cecilia Engler

Articles, Book Chapters, & Popular Press

The ecosystem approach to fisheries management is a conceptual and practical framework consistent with, and supportive of, climate change adaptation at the national and regional level. Implementing an ecosystem approach can contribute to climate change adaptation by improving ecosystem resilience and reducing vulnerability to climate change, by providing planning strategies and tools to monitor and assess the impacts of climate change on fisheries, and by relying on precautionary, flexible, and adaptive approaches that account for the uncertainties, surprises, unpredictability, and dynamism of ecosystems in a changing climate.

In this article, I provide an overview of some key considerations framing the …
