Modeling disease effects animal behavior and population dynamics

Postdoctoral Scientist:
Modeling disease effects on animal behavior and population dynamics - University of Colorado Boulder

The Johnson and Gil Labs at the University of Colorado Boulder seeka quantitative ecologist for a two-year NSF-funded postdoctoral position investigating the emergence and ecological consequences ofparasitic infection in coral reef fishes, with a particular focuson understanding how changes in infection and individual behaviorscale up to affect populations and ecosystems.

The postdoc will join a new NSF Biological Oceanography project ledby PIs Pieter Johnson and Mike Gil examining Black Spot Syndrome(BSS) in roving herbivorous coral reef fishes. Our goal is to understand (1) where and why this parasitic infection is emerging,(2) how infection alters fish foraging and decision-making, and (3) how these individual-level effects propagate to influence fishpopulations, herbivory, and coral reef ecosystems.

A multiscale quantitative ecology opportunity:

A central goal of the position is to connect processes acrossbiological scales: environment & transmission → infection →individual behavior → population dynamics → ecosystem consequences.

The project combines broad empirical datasets with behavioral experiments and ecological modeling. Historical museum collections,community-science observations, and field surveys provide information on changes in infection over a century and throughout the Caribbean. These data, along with novel field experiments,create opportunities to
1) quantify the spatial and temporaldynamics of disease emergence and identify ecological and environmental predictors of infection risk, and
2) developtheoretical models of the behavioral and ecological consequences of infection in reef fish.

The postdoc will play a central role in developing and implementingmultiple components of the project, including analysis of thespatial and temporal emergence of BSS and its environmental and ecological drivers; development and application of population and simulation models; and integration of behavioral, disease, and demographic data to understand the broader ecological consequences of infection. At the individual-to-ecosystem scale, new empiricaldata on how infection affects fish movement, foraging, and decision-making will be incorporated into ecological models.

The Gil Lab and collaborators have an existing large-scale, spatiallyexplicit agent-based model of coral reef ecosystems, providingsubstantial modeling infrastructure on which to build. Aparticularly exciting challenge on which the postdoc will play aleading role will be to connect these individual-based dynamics tomore general…
