Today scientists are increasingly applying modern and evolutionary theory to the understanding of freshwater ecosystems. Taking note of this trend, authors Bronmark and Hansson have compiled a comprehensive overview that summarizes these new approaches and integrates them with more traditional limnology. The result is a comprehensive, accessible resource that fully explores of the evolution of freshwater organisms, the importance of biotic interactions--including competition, predation, parasitism, and symbiosis--and community level processes such as food web interactions. The authors have also included a chapter on conservation that identifies the threats posed by human activity and possible counteractive measures.
