Biodiversity and Evolutionary Patterns in Mediterranean-type Ecosystems
Examine the evolutionary and ecological patterns and processes in the five Mediterranean regions of the world, with a particular focus on the integration of phylogenetic tools in biodiversity science.

Ever since the revolutionary ideas put forward by Charles Darwin, evolutionary studies have played a fundamental role in our understanding of life and the mechanisms that led to its current diversity. The outcomes of the work undertaken as part of this project will be used extensively to promote the use of phylogenetic information in biodiversity research and conservation planning. To achieve this, we use the five Mediterranean-type ecosystems of the world as case studies.
Despite accounting for less than five percent of the world’s surface, the five Mediterranean regions of the world comprise almost 50,000 species and 20 percent of the known vascular plants, and consequently are all considered to be among the 34 global biodiversity hotspots recognized by Conservation International. These five regions (Cape of South Africa, Southwestern Australia, Central Chile, California, and the Mediterranean Basin) have warm and dry summers, sharply contrasting with their cool and wet winters.
Before the Pliocene, the main vegetation type covering these regions was subtropical forest, which was gradually replaced by the current sclerophyllous vegetation, fynbos and renosterveld in the Cape, sclerophyllous forests and matorral in Chile, kwongan and mallee in SW Australia, chaparral in California, and matorral, maquis and garrigue in the Mediterranean Basin.
This project is still in its infancy. Most of the work to date has been done on the Cape of South Africa and the Southwestern Australian Floristic Region, while other projects are currently put into place in the other three Mediterranean regions. It has the potential to ramify in several directions, from phylogenetic diversity, biogeography, and community ecology, to conservation planning.
