Roles of predators and habitat in patterns of mortality of a temperate reef fish  (funded by National Undersea Research Program -- West Coast and Polar Regions Center; National Institute for Undersea Science and Technology) 

         

Several studies have now demonstrated density dependence and the potential for population regulation as an important process in post-settlement mortality of reef fishes.  Because reef fishes (like many organisms) occupy particular habitats, the role of habitat structure and complexity in mediating predator foraging success and potentially altering per capita mortality can be important interactors that may modify the strength of density dependence.

Todd Anderson is investigating experimentally the effects of a  piscivore, the kelp bass, Paralabrax clathratus, on recruitment success of young kelp bass that associate strongly with algal habitats.   As part of this work, the influence of predator size and amount of habitat  on recruitment success is also being explored, with potential implications for marine reserves.
