Our research projects take advantage of molecular genetic approaches to examine diverse questions in ecology and evolution. Primary interests include the molecular mechanisms involved in responses to abiotic stressors in the environment and the role of mitonuclear interactions in the process of allopatric speciation. Much of this work uses the intertidal copepod Tigriopus californicus as a model system, but students in the lab have worked on organisms ranging from microbes to mammals.
Recent Lab News
April 7, 2016 - Our paper is featured in the April 2016 issue of Molecular Ecology. The study, "Transcriptome-wide patterns of divergence during allopatric evolution, " was led by former postdoc Ricardo Pereira (coauthors include Felipe Barreto and Tessa Pierce). The study found that a set of genes that repeatedly shows rapid evolution in independent cases of allopatric divergence consistently shows a strong signal of positive selection. Tigriopus even made the cover of Molecular Ecology! Sébastien Renaut and Anne-Marie Dion-Côté provided a nice News and Views article, see: http://onlinelibrary.wiley.com/doi/10.1111/mec.13577/full
August 26, 2015 - Our new paper on monitoring fish eggs off the SIO Pier got some press! Ph.D. student Alice Harada led the project, along with M.S. student, Elise Lindgren, and undergrad, Maiko Hermsmeier. The Terrill lab (SIO) provided essential physical oceanography support to the team effort!
August 26, 2015 - Bummer for us! Postdoc Felipe Barreto and wife, Dr. Molly Burke, leave UCSD for Assistant Professor positions at Oregon State University. Felipe's work on the Tigriopus genome, transcriptomics and RNAi have helped lead the Burton lab into the genomics era. Congratulations Felipe and Molly and best of luck at OSU!!
August 20, 2015. Lani is now officially Dr. Lani Gleason! Lani models a snail hat in honor of her dissertation work on thermal adaptions in populations of the black turban snail. Lani also survived signing the rafters in Surfside - an SIO tradition for new Ph.D.'s. Starting as a UCSD undergraduate, Lani has been a bright light in the Burton lab for over six years!

Congratulations to Matthew Sasaki who successfully defended his MS thesis on the genetic structure of circumpolar populations of an Antarctic sea star using ddRAD-seq to score over 4000 SNPs. Next up for Matt - a Ph.D. program at the University of Connecticut.

Congratulations to Lori Luers for successfully defending her Master's thesis! Lori presented her work on fine-scale local adaptation to a packed house.
November: Por, Lani, and Reggie attended the Southern California Evolutionary Genetics & Genomics (SCalE) meeting at UCLA on November 15th. Por gave a talk about the differential gene regulation underlying population specific responses to acute heat stress in Tigriopus and Lani presented a poster on her ongoing ddRAD analysis with C. funebralis.
November: Second annual Tigriopus summit: 12 grad students and postdocs gave talks at the joint meeting of the Burton lab , the Willett lab (Univ. North Carolina) and the Edmands lab (Univ. Southern California).
October: Burton lab's first ever presentations at an American Physiological Society Meeting, "Grand Challenges in Comparative Physiology" - Ron gave a talk on gene expression during hybrid breakdown in Tigriopus, Por presented a poster on HSP gene regulation, and Alice presented a poster on population differences in mitochondrial thermal performance.
