The overall objective of BIODIV ISLAND-CONT is deciphering the role of different mechanisms in the generation of biodiversity at all levels, taxonomic (TD), functional (FD) and phylogenetic (PD) by comparing two contrasting biogeographical model systems: islands (Azores, Madeira and Canary Islands), and continental systems (Iberian Peninsula), using spiders as a model organism.
The biogeographical scale of this study has allowed testing basic ecological and evolutionary hypotheses about biodiversity shaping processes by comparing different systems (islands and continents) where the evolutionary dynamics have acted differently on the current biodiversity and community composition patterns.
In this project we have used an integrative approach combining different scientific fields such as taxonomy, phylogenetics, functional ecology, and community assembly under a common methodological and statistical framework, facilitating the application of the findings in relation to future research in the field of evolution and diversification of organisms.
This project has allowed the first islands-mainland system comparison of TD, FD and PD diversity of any organismal group. It will serve as a model for future studies with other taxa, particularly invertebrates, laying the foundations for similar integrative global studies.
Understanding the spatial patterns of biodiversity and their underlying processes is also a fundamental task in conservation biology. Effective conservation strategies should be focused, not only, on preserving individual species or areas, but also on the maintenance of functional and evolutionary processes at different spatial scales, and this project will help to create a bridge between the basic scientific research and conservation managers in this regard.
