We are excited to share this video talk by master's student Hannah Rempel as part of the Global Coral Reef Week conference. Learn about the patterns of coral healing from parrotfish bite scars in one of the most intensively grazed Caribbean coral species:

Both graduate and undergraduate students alike gave fantastic presentations on their work at the Western Society of Naturalists conference in Ensenada, Mexico. Congratulations team!

Our lab is excited to welcome Erin Johnston as a Master student in September of 2019. Before joining the lab at Cal Poly, Erin worked on yellowtail (Seriola dorsalis, formerly Seriola lalandi) distribution, life history, and age in the Southern California Bight in San Diego, where she received her BS in Marine Biology from UCSD. She then worked on recreational fisheries catch data in Orange and LA County for the CA Department of Fish and Wildlife. She will be investigating the effects of climate variability on nearshore groundfish species of the Central California coast in collaboration with the Wendt lab. Welcome Erin! 

Where in the world is the parrotfish research team? Master's student Hannah Rempel and undergraduate research assistants Emma Barton and Peter Vanderbloomer are studying the impacts of parrotfish grazing on coral communities for three months this summer on Bonaire, Dutch Caribbean. This work is part of a broader study comparing patterns and impacts of parrotfish grazing across multiple regions of the Greater Caribbean. ​

 The focus of our work this summer is to: (1) track the healing of an endangered, frequently targeted coral species from parrotfish grazing scars, and (2) compare how the intensity of parrotfish predation on corals varies on islands with high coral cover (e.g. Bonaire) compared to ones with comparatively low coral cover (e.g. St. Croix).

What have we been up to? So far, we have mapped and monitored >100 coral colonies with >250 parrotfish grazing scars! We photograph these individual scars every few days and analyze these images to determine coral healing rates. We are also recording information on parrotfish feeding preferences, parrotfish population size, and coral community composition. ​ Later, we will assess what characteristics of scars, corals and reef sites influence coral recovery rates.

When we are not underwater, we've been organizing a citizen science project with Dive Friends Bonaire to monitor populations of the largest three Caribbean parrotfish species. In addition, Hannah is giving public talks on this research in both English and Dutch Caribbean creole at the Bonaire National Parks Foundation (where she worked before starting her master's) .

It is time for the team to get back underwater and get more data! We look forward to sharing the results of our work with you all in the future.

Thanks for your interest in our field work! Masha danki, muchisima gracias, dank u wel!

Both a graduate student and undergraduate from the parrotfish project team have been awarded funding to support their upcoming research this summer:

Hannah was awarded Best Poster Presentation at the Association of Marine Laboratories of the Caribbean! Congratulations Hannah! Check her poster here.

She was also awarded a AMLC Student Travel Award and a Cal Poly Graduate Presentation Award that allowed her to attend this conference and is thankful for funding to support her travel to present at this conference! 

Hannah gave a great lightning talk on 'Integrating R & Google Drive for Collaborative Research' to make research more user-friendly for less tech savvy collaborators at the SatRday LA 2019 conference!
