Barry Sinervo, Full Professor, University of California, Santa Cruz, is an evolutionary biologist who conducts research on Behavioral Ecology, Game Theory and the Biotic Impacts of Climate Change. He received his HBSc from Dalhousie University with a double major in Mathematics and Biology, PhD from the Zoology Department, University of Washington, and was a Miller Research Fellow at the University of California, Berkeley. Early in his career he discovered the first biological example of the rock-paper-scissors game, played out in nature by the side-blotched lizard. He is co-author with Dan Friedman of a book (Feb., 2016) entitled: “Evolutionary Games in Natural, Social and Virtual Worlds”. He is currently researching contemporary extinctions of reptiles and amphibians and changes in plant communities driven by climate change, at sites distributed on five continents, leading a multinational research team of scientists developing physiological models of the biotic impacts of climate change on diverse biological systems, and measuring the biotic impacts of climate from equatorial sites to polar regions.  He gives workshops on climate change science at institutions around the world.  He is also Director of the UC-wide Institute for the Study of the Ecological and Evolutionary Climate Impacts, a research consortium funded by a UC Presidential Research Catalyst Award, studying biotic impacts of climate change across the UC Natural Reserve System of California. 

Our research is focused on behavioral and physiological ecology. For example, we have described a biological example of a cyclical "rock-paper-scissors" game that is being "played" out among three color morphs of male side-blotched lizards in the Coast Range of California. As in the "rock-paper-scissors" game where paper beats rock, and scissors beats paper, and rock beats scissors; the wide-ranging, "ultra-dominant" strategy of orange males is defeated by the "sneaker" strategy of yellow males which is in turn defeated by the mate-guarding strategy of blue males which is in turn defeated by the orange strategy to complete the cycle. We are currently using DNA paternity analysis to measure success of each color morph under different morph frequencies. The game leads to interesting aspects of cooperation in the blue strategy. We are focusing on the evolution of cooperation, and how this might drive the speciation process.

Questions relating to the physiological ecology of females are addressed by assessing the trade-off between offspring quality and quantity. I have developed two complementary manipulations, egg miniaturization and gigantization, that allow me to experimentally address the physiological bases of egg and clutch size variation as well as its fitness consequences. Current research addresses effects of egg size on dispersal, territory establishment and reproductive success in male and female offspring. Because egg and clutch size also affect the future reproductive success of the female parent, we can also experimentally manipulate such "costs of reproduction" by altering clutch size in the female parent.

Although much of my work focuses on the microevolutionary changes in behavior and physiology of lizards, I am also interested in the evolution of development in marine and freshwater organisms with larval stages (e.g., sea urchins and amphibians). I am also interested in other macroevolutionary problems of evolutionary biology that involve speciation. Our recent work is related to socially mediated speciation rather than ecologtically mediated speciation, which is typically considered in speciation studies.
