Summary:
Large-scale patterns of species diversity, distribution and evolutionary distinctiveness serve as the basis for conservation strategies and for developing the theoretical models needed to predict the impact of global change on biodiversity. However, all global species-level macroecological studies to date have been carried out in vertebrates or plants, and nothing is known at that scale for insects, the most diverse group of terrestrial organisms. ACTIAS proposes to bridge that gap for the first time through a global-scale macroecological analysis of two of the best-documented families of moths.

Benefiting from the wealth of diversity, distribution, ecology and phylogeny information available, including a DNAbarcode database for 95% of the world species, we will use spatial distribution modeling methods to document the distribution of diversity and of its evolutionary distinctness, and to highlight areas where these are concentrated and most threatened.
Because the spatial and temporal dynamics of speciation are expected to cause disparities in the observed patterns, we will explore the role of species-traits in shaping current diversity and distributions by combining traits and comparative phylogeographic analyses in New World species. These results can provide an objective ground for finetuning the theoretical models within subgroups and for their application in other regions of the globe.
