Beschreibung
This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.
This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance Combines theoretical issues with technical developments such as mapping distributions Addresses the limitations that still exist in understanding the relationships between scales and the importance of distribution ecology in determining key factors that affect species conservation status Includes supplementary material: sn.pub/extras
