Recent experiments in macrophyte dominated communities on the relationship between biological diversity and ecosystem functioning suggest that effects and mechanisms of genetic-genotypic and species diversity are analogous. As previously shown for species diversity, genotypic diversity enhances ecosystem productivity and recovery from disturbance. These findings generalize ecological theory, and provide an empirical basis for explicitly considering the maintenance of genetic or genotypic diversity for conservation strategies. Macrophyte systems such as seagrasses or salt-marshes may be excellent systems to test the interaction between diversity across several (genetic versus species) levels of biological organization because they are relatively species poor while simultaneously allowing the manipulation of genotypic diversity by taking advantage of clonal propagation in many species.
