Please read below to learn a little more about each student's research. As always, please also check out the posts highlighting student research from previous years as well at the following links: 2019, 2018, and 2017.
Special author note: As I am one of the students that defended and graduated this year, this will be my last post for The Drop-In. From writing about classes to conferences and student research, it's been a pleasure writing for this blog. Hopefully someone else will carry the torch forward in the new year to highlight and celebrate the research of graduating students!
Congratulations to MLML alumna Sharon Hsu who recently accepted a fantastic new job with the Center for Coastal Studies as an aerial observer on their North Atlantic right whale team! Sharon received her MS in Marine Science from SJSU/MLML in 2020. Her thesis research in Dr. Gitte McDonald's Vertebrate Ecology Lab focused on stable isotope analysis in leatherback sea turtles.
Congratulations to SJSU/MLML Ichthyology Lab alumna Devona Yates on the recent publication of her thesis research in the journal Marine Ecology Progress Series! Devona’s paper, co-authored by Professor Scott Hamilton, examines the effects of marine reserves on predator-prey interactions in central California kelp forests.

While working on the latest Moss Landing Marine Laboratories Annual Report, my friend and fellow MLML student employee Caroline Rodriguez collected a bunch of amazing photos from the Moss community. While she used many of the best shots in the final report (check it out here!), there simply wasn't enough room for all of the great photos she had amassed. So Caroline reached out to me and asked if I was interested in compiling all these images into a post on The Drop-In blog. And as you can probably guess since you are reading that very post, I said yes!
After a year of mostly staring at screens and working from home, looking through these images of fieldwork, amazing animals, and beautiful scenery taken by my wonderful peers, professors, and colleagues over the last few years has been a great reminder of why I chose to come to MLML in the first place. I hope you enjoy them as much as I did. So, without further ado, I present a glimpse into the highlights of life at Moss Landing Marine Laboratories as told by photos from the MLML community.
I think it’s safe to say that before the start of this year, no one could have possibly predicted the truly wild twists and turns of 2020- and the year isn’t even over yet! The ongoing Covid-19 pandemic has radically altered the world and for most folks, life over the past 8 months has been pretty chaotic and stressful. I never imagined that on top of all the regular day-to-day stress of graduate school, I would also have to deal with a deadly pandemic, but here we are!
So what exactly has life as a grad student been like during these very strange Corona-times? Lots of people have asked me that question since March, and I typically respond some variation of stressful/overwhelming/profoundly boring/way too much time spent on Zoom. If they happen to catch me on a good day where I have made some big breakthrough with my thesis or had a super productive morning then I might even tell them it’s not so bad. In truth, grad school during a pandemic is a lot like grad school during a normal year: highs and lows. Except now I (almost) never leave my house. So, without further ado, I present a brief Buzzfeed-style look into my life as a Moss Landing Marine Labs (MLML) grad student during the Covid-19 pandemic.

Endings are Beginnings
In a forest when something dies--a leaf, a plant, an animal-- it likely settles onto the ground where it begins a process of decay and integration into the layers of earth beneath. Unless it's carried far away by a scavenger, it mostly stays local after it dies, becoming a part of soil nutrient and mineral cycles at most a meter deep.

When I was a child, I used to be mesmerized by seaweed swaying in the surf when I went tidepooling or kelp flowing back and forth in the currents at the aquarium. I loved finding underwater plants because it always meant that I was going to find some amazing animals, too. Whenever I went wading into a meadow of seagrass, I would place my feet cautiously to avoid the crab claws that could suddenly shoot up. If I brushed aside some sea lettuce near a cluster of rocks, a fish might quickly flutter away into a new hiding place. Aside from the plant properties that they all share, these seagrasses and algae also have something else in common: they served as foundation species for their communities.
Just like trees in a forest, these underwater plants are essential to the very identity of their ecosystems. They dominate them, shape them, alter them, define them. A kelp forest ecosystem doesn’t exist without the kelp, nor is a seagrass meadow a meadow without the seagrass. All the other members of their ecosystems directly or indirectly rely on the foundation species in some way. For example, young rockfish tend to gather in kelp forests to hide from predators. I’ve always loved to learn about foundation species, even before I knew what the term was. It’s almost an instinctual thing that we already know. When you enter a new place or conjure an image in your mind, foundation species are usually the first to stand out, such as corals in a coral reef or evergreens on a mountain.
The reliance on a single species means that researchers need to give special attention to the conditions that species thrives in. Any changes that the foundation species experiences will inevitably trickle down to the other community members. Going back to our example, if the kelp that make the kelp forest are unable to thrive, then the young rockfish will have to go somewhere else to hide. Oftentimes, underwater plants are sensitive to specific temperatures or specific depths. They may grow very well in places that have the right mix of conditions, but will no longer flourish if those conditions happen to change from what the plants need. Similarly, if an area nearby changes to suit them, then they can move right in.
The combination of suitable conditions for underwater plants helps define their range, or the area an organism can be found. Over time, that range can shift. Our planet is experiencing a period of rapid climate change, which is predicted to shift the ranges of underwater plants as coastlines experience new sea levels, new temperatures, and more. Since so many underwater plants serve as foundation species, the range of the animals that rely on them may shift also.
By understanding what our underwater plants need to survive and flourish, scientists can model and predict where we can expect to find these foundation species over time. In general, since many underwater plants are limited by temperature, most are seeing a shift northward as global temperatures warm up. We can then predict that the organisms attributed to these foundation species could see a northward shift as well. This could mean in the future, if I want to wade out into a seagrass meadow and try to find my crabs, I’ll have to drive further north a little longer.

Dr. Holly Bowers had an awesome experience as a visiting researcher at the Cawthron Institute in New Zealand in 2020! Although she has previously collaborated with some of their team, those relationships were expanded upon and new ones were formed during this visit. She worked closely with the Biosecurity Team to run two experiments testing different filter types and filtration times for efficient eDNA and eRNA capture, using the dinoflagellate Alexandrium as a model species. An eDNA/eRNA review paper with a biosecurity angle is in the works.
With the Safe New Zealand Seafood Programme she worked to expand geographic specificity testing for qPCR assays targeting four species within the toxin-producing genus Pseudo-nitzschia. A continuing collaboration with the team aims to characterize species diversity and toxin production of a subset of Pseudo-nitzschia species around New Zealand. She returns with an expanded knowledge base and heaps of ideas for future collaborations!
