WELCOME BY GIL ROSENTHAL

The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' but 'That's funny...'

- Isaac Asimov

Our lab's research focuses on mate choice and its consequences: we seek to understand how mating preferences and sexual signals work and how they evolve, and in turn to understand the role that mate choice and signaling play in shaping basic ecological and evolutionary processes. We work at the interface of animal behavior and evolutionary genomics. Our primary focus is on visual and chemical communication in teleost fishes, integrating observational and experimental studies of behavior with next-generation molecular methods. We enjoy collaborating with other labs with complementary areas of specialization.

Our lab at TAMU includes extensive indoor space for experimentation and animal housing. Our CICHAZ research station in the Sierra Madre Oriental of Hidalgo, Mexico, is currently undergoing a major renovation and expansion thanks to NSF funding. An array of over 50 mesocosms for experimental work is already in place, and state-of-the-art facilities for molecular biology and aquatic husbandry should be complete before the end of 2019. The station is home base for field and experimental research on natural hybrid zones of swordtail fish. Hybrids between Xiphophorus malinche and X. birchmanni (Poeciliidae) represent a ‘genomic collision’ between two species with divergent communication systems, and provide a terrific opportunity to understand both the genomic architecture underlying mate choice and the fitness consequences of novel sexual phenotypes in the wild. Major funded research projects include (1) an NSF LTREB project combining population, quantitative, and evolutionary genetics with morphological studies of male signals and behavioral studies of mate preference; (2) elucidating the mechanisms linking variation in learned mate preferences with behaviors under ecological selection; and (3) using phylogenomics to understand how the divergent reproductive mechanisms shape macroevolutionary signatures of genetic exchange.

TAMU offers excellent intellectual and physical resources in both the Biology Department and the broader PhD program in Ecology & Evolutionary Biology . Subtropical Bryan/College Station is within easy reach of Houston, Austin, and an array of ecologically distinct natural areas. If you are interested in applying for a PhD position in the lab, please review Rosenthal lab publications and read the prospective graduate student page. Undergraduates from TAMU and elsewhere interested in doing research are encouraged to read the undergraduate research page.
