Geographical and environmental impacts on symbiotic relationships between anemone and algae

Corals and anemones form a symbiotic partnership with photosynthetic algae based on an exchange of nutrients: the host receives sugar from the algae, the algae receives nutrients and consistent exposure to sunlight from the host. This relationship can break down under stressful conditions, a phenomenon known as 'bleaching,' which, in the case of tropical corals, can quickly lead to the death of the host. Bleaching resistance can arise if a local population consistently encounters and adapts to warmer conditions.

Long Term Impacts of Marine Heatwave on Kelp Forests

A new study led by researchers at UC Santa Cruz, with coauthors from UC Berkeley, UCLA, UC Santa Barbara, and UC Davis, documents the collapse of kelp forest ecosystems off the coast of Northern California. Analyzing the contributing events, from warming oceans to the loss of sunflower sea stars, researchers used satellite imagery from over 30 years to assess historical changes and better understand the dynamics and resilience of kelp forests.

Kelp: California's Coastal Forests

Kelp: California's Coastal Forests

Written by Jane Park

Using science to inform the restoration of California’s underwater forests

Kelp forests are underwater forests that support some of the world’s most productive fisheries and unique ecosystems.  Kelp forests occur throughout the world.  California’s kelp forests are particularly unique, as our “redwood forests of the sea” are among the tallest and most productive of the world: Northern California’s “bull kelp” grow an average of 4 in./day and can reach heights over 100 ft. 

My summer with remote research

Climate change is a pressing issue that is and will continue to affect all life on earth. Throughout these past 10 weeks, I have had the rare opportunity to study the effects of ocean acidification on the calcification of different marine animals, specifically in environments that these animals will naturally face within the next century. Before this internship, I did not have much knowledge regarding this topic, but after working with my peers and mentors, I realized the importance of this work and have found this to be both an eye opening as well as an enriching experience.

Species Resilience and Science Advocacy:

In the lab

Genetics, climate change, and conservation become highly intertwined in Dr. Andrew Whitehead’s lab. Although he works on a variety of research endeavors, he mainly focuses on how wild species respond to human-induced stress, such as the effects of climate change, and how that may affect an individual organism’s progeny. Essentially, Dr. Whitehead attempts to monitor how climate change and pollution will shape the genetic makeup of multiple generations.
