My research applies the science of evolutionary ecology to conservation and management of fisheries. I study the evolution of fish species with complex life histories. I use demographic models to understand how biological differences interact with fishing, including fishing intensity and gear type. This information is critical for managing species sustainably and identifying threatened species.
Inferring the status of Data Deficient species using ecological principles
My group, along with colleagues at UC Santa Cruz, Simon Fraser University, and University of Glasgow are working to combine and analyze fish life history traits, survey data, and stock assessments from fisheries around the globe, which are increasingly available for large-scale analyses. These data offer a unique opportunity to use modern computational methods (e.g., Bayesian state-space methods) to infer the status of a population or species without traditional assessments – something that is urgently needed for many fish species. We received funding from the National Science Foundation to impute the trajectories of data-poor populations by using informative priors and information on species with shared traits (i.e., related species, or species caught in the same habitat). We are developing a hierarchical framework to assess the status of high-value marine fishes that have limited abundance data, such as tuna relatives, groupers, and sharks and rays.
This approach is only feasible because it takes advantage of our existing knowledge of life-history evolution to generate informative priors on the Bayesian models. However, for many marine species, we still lack a robust understanding of the relationship between life history, demography, and population dynamics. For example, we cannot yet predict how the population dynamics of an egg-laying skate will be different from those of a live-bearing stingray. I have a current project developing evolutionary models to predict the co-evolution of traits such as growth, body size, and reproductive traits (e.g., mating system). In this case I am focused on using state-dependent models to incorporate predation risk and prey availability – using marine size-spectra theory – into models predicting growth and reproduction
Interactions between fish mating systems and fishing
Ecological models tend to assume reproduction is captured a single parameter, but fish biologists know there is so much more to it. My research seeks to understand how social interactions among males and females affect growth, recruitment, and population dynamics. This question is especially interesting if fishing selects one sex (e.g., large males) more than the other. I have worked on this question in multiple systems, including small stream fish like swordtails and darters, as well as marine wrasses and salmon, which migrate between fresh and saltwater. These species all have multiple male mating behaviors, which can make male and female interactions very interesting. This research integrates fundamental concepts and techniques from population ecology, phylogenetics, and behavior.
