Predicting species occurrences : issues of accuracy and scale

摘要: Predictions about where different species are, they are not, and how move across a landscape or respond to human activities - if timber is harvested, for instance, stream flow altered important aspects of the work wildlife biologists, land managers agencies policymakers that govern natural resources. Despite increased use importance model predictions, these predictions seldom tested have unknown levels accuracy. "Predicting Species Occurrences" addresses those concerns, highlighting researchers strengths weaknesses current approaches, as well magnitude research required improve test currently used models. The book an outgrowth international symposium held in October 1999 brought together scientists at forefront efforts process information spatial temporal scales. It comprehensive reference offers exhaustive treatment subject, with 65 chapters by leading experts from around world that: review history theory practice modelling present standard terminology; examine scales terms their influence on patterns processes distribution; offer detailed discussions state-of-the-art tools descriptions methods assessing accuracy; discuss predict presence abundance; examples spatially explicit data demographics can provide managers. An introductory chapter Michael A. Huston examines ecological context which occurrences made, concluding John Wiens insightful synthesis topics examined along guidance future directions cautions regarding misuse Other contributors include P.
