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.

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.

Sea urchins may have a spiny reputation, but they are vital members influencing kelp ecosystems. Join us as Delaney Chabot, a third-year Master Student in Integrative Biology, discusses their importance and also how they act as a connecting link between subtidal and intertidal zones. Delaney is a passionate educator and the visionary behind the 'kelp horn' - listen in to hear more! Hosted by Matt Vaughan and Taylor Azizeh.

Mammals encompass some of the most interesting animals on the planet. We can see how bats have mastered the sky with wings like birds or how dolphins have adapted streamlined bodies for life in the ocean just like fish. The ability to evolve similar characteristics to overcome common problems found in the environment is called convergent evolution and opens our eyes to the fundamentals of how life has changed to face the challenges of our planet. One such trait that is the product of convergent evolution is echolocation, which is the subject of research for our guest on the show this week Serena Frazee.
