David Franklin, summer 2014 REU Cohen lab intern, wins first poster prize at Society of Integrative and Comparative Biology meeting in West Palm Beach, Florida (January 2015) in the Division of Phylogenetics and Comparative Biology, for his poster, Distribution of Acartia spp. in central San Francisco Bay and San Pablo Bay is not related to temperature and salinity , coauthored with Carrie Craig, Ann Holmes, and Sarah Cohen.

In collaboration with the Kimmerer lab, we presented two posters at the annual meeting of the Society of Integrative and Comparative Biology, held this week in West Palm Beach, Florida.

Interview with Laura Melroy about sea star phylogeography using historic collections from the California Academy of Sciences along with contemporary sampling. Stanford Journalism Master's student Shara Tonn produced the video that also features SFSU Master's alumna and CAS Marine Invertebrate Collections Manager Chrissy Piotrowski.

Herring are back in San Francisco Bay! You can find news about SF Bay herring spawning and harvesting activities on the Department of Fish and Wildlife website.

Carrie Craig presents her thesis defense at RTC on December 17: "Investigating the diets of nauplius larvae and adults of a predatory copepod using DNA barcoding"
