Kelp are an important foundation species in Oregon, however are experiencing multiple stressors that may directly influence their biomass, including rising ocean termperatures and being preyed upon by sea urchins. Furthermore, Oregon is in talks of reintroducing sea otters back into the environment - what does this mean for kelp? In this episode, Andrés explains how he is assessing the interplay between kelp and sea urchins through simulation modeling with the goal of better informing agencies. Hailing all the way from Ecuador, listen in to hear the inspirational journey that led him to grad school in Oregon. Hosted by Matthew Vaughan and Hannah Stuwe.

How do you identify “an expert”? The answer to this question is more complex than you might think. Most of us might think of people with multiple degrees or extensive experience in a specific field as experts. However, as our guest this week is discovering, experts can be people with passion, people with connections or people with specific job titles. Recognizing the enacted and relationally valued characteristics of an expert is essential to creating systems where experts that reflect a community’s ideas and values are the ones making the decisions. One example is the community of people around and connected to the Puget Sound watershed region and the jurisdiction of the Puget Sound Partnership: an area spanning 12 counties and 28 recognized Tribal Nations. Large restoration efforts are underway to restore Puget Sound and prime the ecosystem for climate adaptation. These efforts hinge on not just access to climate adaptation knowledge, but who is recognized to apply such knowledge and the social structures to shape its uptake. Our guest this week is Krista Harrington, a 4th year PhD Candidate in the Department of Fisheries, Wildlife, and Conservation Sciences. Krista utilizes political ecology and science, technology, and society theory in environmental natural resource management. During her Bachelor’s degree, Master’s degree and time spent working in wildlife conversation, she kept asking herself “who are we going to for expertise?”. This question ultimately shaped the path of her PhD work and is how she is contributing to restoring Puget Sound. Hosted by Emilee Lance and Esteban Hernandez

Blue whales (Balaenoptera musculus) are the largest animals that have ever existed on Earth. Despite this, they feed exclusively on krill (Nyctiphanes australis) which are typically no larger than 2 cm. Thus, they must consume massive amounts of these tiny organisms to support the large energy requirements of their life history processes. Researchers are interested in understanding how predator-prey dynamics between blue whales and krill may shift with changing ocean conditions. Nicole Principe is a 2nd year PhD student in the Geospatial Ecology of Marine Megafauna (GEMM) Lab at the Oregon State University Marine Mammal Institute, led by Dr. Leigh Torres. Her PhD work is part of the SAPPHIRE (Synthesis of Acoustics, Physiology, Prey, and Habitat in A Rapidly Changing Environment) Project and will focus on blue whales in the South Taranaki Bight in Aotearoa (New Zealand). This interdisciplinary work involves using oceanographic data, active acoustics for prey, drone imagery (i.e., photogrammetry), and hormone analysis to investigate the availability of krill and blue whale health and population resilience to climate change.

Join us for a chat with Jazlee Crowley, a 4th year PhD student in Integrative Biology who takes us on a deep dive into the complex interactions of the bodhi tree. Jazlee's research takes us to Hawaii, but as we soon learn, relationships with the bodhi tree are prominent in many countries and cultures. As Jazlee investigates the role of the bodhi tree in Hawaii as an "invasive", it becomes apparent that her research sits at an intersection of science, philosophy, spirituality and culture. Hosted by Matthew Vaughan and Emilee Lance.

Oregon’s many winding rivers meet the Pacific Ocean in gorgeous estuaries scattered along the coastline. These estuaries are critical habitat for salmon, water birds, Dungeness crab, and oysters, and are deeply connected to the local economies of coastal communities. These estuaries are also the primary habitat of eelgrass — a fully aquatic flowering plant. We may overlook eelgrass as the creepy thing under the waves that brushes against your foot while wading through the water, but it is actually incredibly important to coastal ecosystems. It protects against erosion, absorbs pollutants, provides breeding grounds for many fish and invertebrate species, and can act as carbon sinks. Unfortunately, eelgrass is disappearing because of dredging, development, and sea level rise. The good news is that researchers are actively investigating how to best restore eelgrass habitat. Olivia Boisen, a fifth year PhD student in the department of Fisheries, Wildlife, and Conservation Sciences, is one of these researchers. As part of her research in the lab of Scott Heppell, Olivia is investigating several estuary sites along the Oregon coast where restoration practices are being implemented. Through this work she is able to determine the effectiveness of certain restoration practices on eelgrass recovery, and subsequently how various fisheries species respond.

What happens when the rich agricultural landscape meets the rugged and wild natural ecosystems of eastern Oregon? Join us as we sit down with Lara Mengak, a 4th year PhD student who is exploring this question. Her dissertation work is trying to understand what social and ecological threats impact ranchers in Oregon. What kinds of conflicts exist between natural predators, such as wolves, and livestock? What are the best ways to mitigate these conflicts? How do we manage landscapes to support wildlife conservation and agriculture? How do these things vary as a function of climate change or drought? Listen is as Lara tells us about her winding and inspiring journey that led her to the intersection of conservation science and agriculture. Hosted by Matthew Vaughan and Taylor Azizeh.
