| Abstract: | Ecologists and natural resource managers struggle to define and relate biodiversity, biocomplexity, ecological integrity, ecosystem services, and related concepts; to describe effects of disturbance dynamics on biodiversity; and to understand how biodiversity relates to resilience, resistance, and stability of ecosystems and sustainability of resource conditions. Further diversifying this “lexicon zoo” are the ecological roles of rare species and refugia, and measures of surrogates and indicators of biodiversity parameters. To impart order on this lexicon zoo, a “concept map” framework is suggested for clearly defining biodiversity parameters and related terms, relating biodiversity to ecosystem services and sustainability, describing how disturbance affects biodiversity, and identifying biodiversity parameters for management and monitoring. Many relations among these concepts are poorly understood in managed forest environments and are presented here as testable tenets. |
