Taxonomic turnover in terrestrial and aquatic diatom communities: integration of macroecological, morphological, phylogenetic-evolutionary and ecophysiological approaches. 01/01/2007 - 31/12/2010

Abstract

The current proposal aims at contributing to a better understanding of the relationship between historical-evolutionary, ecological and neutral mechanisms and observed patterns in endemism, latitudinal diversity gradients and regional species turnover in terrestrial and lacustrine diatom floras. We will therefore (1) construct the first global, intercalibrated, species-level taxonomic dataset for these diatoms; and (2) using our extensive culture collection, and for a selection of representative genera and species(complexes), investigate (i) to what extent phylogenetic history can explain the geographical variation in diversity patterns at the population, species and genus level and (ii) how these patterns correlate with variation in life history characteristics and ecophysiology amongst and within species.

    Micro- and macro-evolution of the threatened endemic giant Opuntia cacti: conservation genetics on the Gal√°pagos archipelago. 01/10/2004 - 31/12/2007

    Abstract

    This project will study micro- and macro-evolutionary processes (changes in allele frequencies, genetic drift, gene flow, hybridisation, introgression, changes in DNA sequences) within the threatened giant Opuntia-cactusses on the Galápagos islands. Therefore we will combine several recently developed, genetic techniques (microsatellites, DNA sequencing), studying a unique, already available collection of samples.
