Joe Jackson

Jacksonj@sonoma.edu


I am a community ecologist that is also interested in the roles that foundation and keystone species play in their environment. I specialize in coastal marine environments, most prominently in estuaries along with some experience in the rocky intertidal. I earned my B.S. at Sonoma State University looking at physiological responses to stressors in mussels, which is where I found my passion for coastal ecosystems. However, I knew my goal would be to pursue a career in ecology from the start. My Master’s project will be looking into how the presence of non-native species in estuarine ecosystems can impact the prey items and recovery speed of top predators (Enhydra lutris).

Maddy Sanchez

sanchmad@sonoma.edu


I received my B.S. in Biological Sciences with a concentration in Ecology from California State University San Marcos. As an undergraduate, I developed a passion for wildlife ecology and conservation while studying wildlife corridors in San Diego County. I am currently a first-year graduate student at Sonoma State University with interests in southern sea otter foraging behaviors. For my thesis project, I will be exploring predatory soundscapes and the ability of audio recorders to quantify southern sea otter predation on crabs in the Elkhorn Slough estuary (Monterey, CA). I hope to continue research and field work in wildlife ecology after completing my Masters.   

Jessica Saavedra

saavedrj@sonoma.edu

Hi, I’m Jessica Saavedra. I received my B.S (Ecology and Evolutionary Biology Concentration) at Sonoma State. As an undergrad, I was involved in a couple of projects such as determining the effects of native food web structure on populations of the invasive European green crab, (Carcinus maenas), analyzing scat of the American badger (Taxidea taxus) to determine their diets, etc. As I got into my final year of undergrad, I grew a passion for marine conservation and ecology. My current research investigates how the recovery of sea otters (Enhydra lutris), affect their invertebrate prey within a seagrass (Zostera marina) ecosystem in southeast Alaska.

Alyssa Baldo Cooper

cooperaly@sonoma.edu

I am a fish ecologist interested in understanding the environmental factors that allow the young of certain species to thrive. I completed my B.S. in Marine Biology at the University of California, Santa Cruz looking at the effects of climate change on fecundity in rockfish. That, along with many scuba diving courses solidified my passion for both immersing myself in the underwater world and investigating the interactions of its inhabitants. I have interned for NOAA and have worked for the Department of Water Resources and a fish ecology lab at U.C. Davis. My Master’s project will focus on the feeding ecology of leopard sharks (Triakis semifasciata) and bat rays (Myliobatis californica) within estuaries and why this particular habitat is such a hotspot for natal activity.

Rachael Karm

karmr@sonoma.edu

Hello! I am Rachael and I am a master’s student in the Hughes Lab. Prior to becoming a Seawolf I received my B.S in Marine Biology from UC Santa Cruz. As an undergraduate I fell in love with both SCUBA diving and kayaking. Both of these experiences along with my classes further enhanced my passion for marine community ecology. Now, I am honored to be a part of a collaborative effort studying the Northern California bull kelp population. The bull kelp forests are diminishing and as a team we are looking at how temperature affects the growth throughout kelp life history stages and the possibility of reforestation. 

Undergraduate Students

Natasha Higuera

I am a fourth year undergraduate biology student. I have a concentration in ecology and evolution and have been focusing on the field marine ecology. Growing up on the Mendocino coast in California pushed me to want to know more about our ecosystems. The small town I come from is heavenly dependent on fisheries and tourism, two things that have to find a balance in order to be sustainable. My research is thus typically involving organisms or ecosystems that affect the public. Currently, my research is focused on kelp forests, primarily bull kelp. 

Luke Vanderkar

Hey! My name is Luke Vanderkar and I’m finishing up my Biology degree at Sonoma State University with a concentration in Marine Biology. I’m also a certified advanced scuba diver. My main interest is in marine mammals and their ecological interactions. I have an extensive passion for the ocean and am very excited to get out in the field and be able to contribute to sea otter recovery.

Byron Whittle

Hi I’m Byron and I am just finishing my degree in biology with a concentration in marine sciences. I have a passion for marine life and the different species interactions, both on the macro and micro scale. I am excited to join this team and explore the North Pacific intertidal, more specifically the predator prey relations that take place. Just grab a tank and get in the water to unveil the mysteries that await.
