Biological diversity is distributed in the space at various taxonomic levels: from genes to ecosystems. Describing and understanding the spatial distribution of biological diversity and the processes that underlie it is central in population genetics and community ecology. It can reveal important insights into evolutionary processes, population and species history, and, ecological factors that shape variations. Understanding these patterns is also key to preserving biodiversity and guiding conservation efforts. Theory predicts that similar evolutionary processes (drift, dispersal, selection) acting along a micro (genes) – macro (species) continuum drive the both levels of diversity. If micro- and macro-evolutionary scales are governed by analogous evolutionary processes, then spatial patterns of intra- and interspecific diversity should covary. I will illustrate from marine fish how spatial congruence between genetic diversity within species and specific diversity within communities appears to be context-dependent.
