The closer you look, the more you see. European butterfly diversity through the magnifying glass of phylogeography

CitaciónXIXth European Congress of Lepidopterology (2015)
ResumenOur work as biologists, as well as our passion as lepidopterists, is describing bio-diversity at all levels, understanding how it is generated and maintained, and, of course, finding ways to protect it. Technical advances, especially recent molecular techniques, but also morphometric and chemical analyses, are unfolding a previ- ously invisible layer of complexity: genotypically and phenotypically differentiated lineages, evolutionary significant units, and even cryptic species. This new viewpoint brings a wealth of knowledge, but also of challenges and questions. How to methodologically approach the enormous descriptive task at the fine phylogeographic scale? How much should we invest on deeply studying each taxon in the quest for cryptic diversity? Can we develop methods for comparative phylogeography? Grey zones in the classical systematic classification become now enhanced, but eventually novel results have to be harmoniously integrated into the previous evidence and taxonomic corpus. Does recognising cryptic diversity represent a rather meaningless burden for monitoring and conservation, or does it have fundamental implications for biogeography, ecology and the preservation of existing diversity? Even if butterflies are an exceptionally well-studied group of invertebrates, a good number of cryptic species are still being discovered or confirmed. But most importantly, novel data give us some clues to answer the previous questions.
