UC Santa Cruz - Newsletter

Greetings,

At UC Santa Cruz, we are fortunate to be situated in a biodiversity hotspot. Our coastal area is home to a tremendous number of different species, many of which are found exclusively in the Santa Cruz area. We rely on our coast and uplands for sustenance, recreation, and well-being. 

However, these same areas are in peril. Our rapidly increasing human population is putting tremendous pressure on our coasts. Overfishing, pollution, human development, climate change, and rising sea levels are all contributing to their rapid decline.  

At UCSC, we strive to protect these important ecosystems, which are vital not only to our own survival as a society, but also to the health of our planet. That is why we have made Coastal Sustainability one of our top priorities. 

UCSC is internationally recognized for its leadership in marine and coastal research. Our goal is to expand our impact on science, society, and the environment by partnering with others. We are building programs that aim to solve the complex problems of sustainable living on the coast by investing in research and teaching our students and the public about what we’ve done and what we’ve learned.

Featured Students - Roxanne Beltran and Nissa Kreidler

Roxanne Beltran and Nissa Kreidler are Ecology & Evolutionary Biology undergraduates at UC Santa Cruz who have done outstanding field research. Their work began as part of the Ecology and Conservation in Practice supercourse taught by Don Croll, Erika Zavaleta, and Gage Dayton. Equivalent to four separate classes, this 19-unit course is the only one students take during Spring quarter. They travel to multiple UC Natural Reserves all around the state, where they gain hands-on experience in biology fieldwork. 

During the final part of the course, the class performed fieldwork on Santa Cruz Island, located in the Channel Islands. Santa Cruz Island was once the site of a large sheep ranching operation. The sheep roamed and grazed freely on the island for much of the 19th and 20th centuries. Santa Cruz Island eventually became home to the largest feral sheep population in the world. As the demand for wool fell, production dropped and ranching was abandoned in the 1940s. But the sheep remained. Long-term overgrazing by the sheep devastated the island’s habitats. A program to remove the sheep was started by the Nature Conservancy in the 1980s. Today, there are no sheep left on the island. 

The students read a paper published in 1987 by Dr. Dirk Van Vuren, which outlined in detail the effects sheep ranching had on the vegetation of Santa Cruz Island. While on the island, their goal was to determine how much the island has recovered since Van Vuren’s original study. The class observed some interesting trends that suggested the ecosystem was recovering. 

After the course was over, Roxanne and Nissa chose to continue studying the changes that had taken place on Santa Cruz Island since the elimination of feral sheep.  They wanted to find out in more detail how much passive restoration has impacted the recovery of the island. The two students tracked down Dr. Van Vuren, who responded with great enthusiasm. He provided Nissa and Roxanne with his raw data, original site locations, and long-term photos from 30 different sites around the island. Nissa and Roxanne created a research plan to compare changes in floral cover and community composition 30 years after the removal of sheep. The two students, along with a few other members from their field course, returned to Santa Cruz Island to conduct a study using the exact sites from Van Vuren’s original study. They found a successful recovery back to perennial, native woody cover, confirming the efficiency of passive restoration efforts. 

Roxanne and Nissa have written a paper on their research, and are submitting it for publication in a peer-reviewed journal.

Featured Faculty - Terrie Williams

Terrie Williams is one of our distinguished faculty members in the Department of Ecology & Evolutionary Biology. She is the Director of the Marine Mammal Physiology Program. Her innovative use of video cameras and computer modeling revealed many previously unobserved behavior in marine mammals, earning her recognition by Discover Magazine as one of the 50 Most Important Women in Science.

Terrie Williams was recently awarded the AAAS/Subaru SB&F Prize for Excellence in Science Books for her new book entitled, The Odyssey of KP2: An Orphan Seal, a Marine Biologist, and the Fight to Save a Species. The book chronicles her experience as a marine biologist working with an abandoned monk seal pup known as KP2. Monk seals are a critically endangered species, with only 1,100 individuals left. Her research with KP2 has played an important role in gathering knowledge and data about this little-studied species. 

KP2 was abandoned by his mother when he was only 2 days old and was harassed by the other monk seals on the beach. Because this species is on the edge of extinction, a difficult and controversial decision was made to rescue the seal and rehabilitate him. He learned how to feed, hunt, and swim, and he was eventually released back into the wild. Unfortunately, because of his long exposure to humans early in life, KP2 was drawn to them. He took up residence at a beach on the island of Molokai, and his fearlessness of humans and playful personality quickly turned him into a local sensation and a YouTube celebrity. Efforts to relocate the seal were made, but he always found his way back to his beach in Molokai. When his play fighting was getting a little too aggressive, officials became concerned about safety and removed KP2. Eventually he was brought to Terrie’s laboratory at UC Santa Cruz. Terrie was able to perform research that answered many questions about monk seals, including what their dietary needs are and what water temperatures are ideal for them. 

The Odyssey of KP2 is a heartwarming story that describes the relationship between a monk seal and a marine biologist. Terrie is very open about the challenges and struggles she faces as a research scientist. Her style of writing is clear and engaging, and makes the book easily enjoyable and easy to understand by scientists and nonscientists alike. 

Terrie hopes her book will raise awareness about monk seals and about what it takes to save a species. Parts of proceeds from the book will go directly to support Hawaiian monk seal research and public outreach at UC Santa Cruz. To find out about ways you can help monk seals, click here.
