Dr. Bryan Brown

Biological Sciences

I study community ecology in aquatic systems. Work in my lab revolves around experimental tests of ecological theory and relies heavily on field experimentation. The four main themes are:

  • The ecology of symbiosis
  • The metacommunity concept in aquatic ecosystems
  • The influence of habitat heterogeneity on community stability
  • Effects of perturbations on aquatic communities
