Diversity and evolution of the floral morphospace.

Morphospaces are mathematical descriptions used for studying the evolution and distribution of morphological diversity (disparity). To do so, a common procedure is the calculation of disparity indexes that allow quantifying and comparing morphological disparity among groups. In addition, reduced (2- or 3-dimensional) representations of the space can be built in which similar morphologies fall close to each other.

The aim of my research is to use a morphospace approach to describe and quantify the morphological diversity of flowers, with the angiosperm order Ericales as study model. This works adds in to the evolutionary biology field of research aiming at understanding the origin and the evolution of floral phenotypes, and their particular distribution among angiosperm clades.

Ericales belongs to the asterid clade and, with more than 11,000 species, comprises ca. six per cent of the eudicot species diversity. The 22 currently recognized families include among many other well-known taxa tea (Camellia sinensis, Theaceae), kiwi (Actinidia deliciosa, Actinidiaceae), persimmon and ebony (Diospyros, Actinidiaceae), pitcher plants (e.g. Sarracenia, Sarraceniaceae) and many horticulturally important genera (e.g. Impatiens, Balsaminaceae; Primula, Primulaceae; Rhododendron, Ericaceae). Ericales are highly variable in their ecology, their vegetative morphology, and in particular their floral structure.

I use non-parametric ordination methods and statistic methods based on distance matrices to build and analyse a morphospace in which I compare the relative position of the 22 ericalean families. I then quantify and interpret the disparity of these groups in the light of their taxonomic diversity, their evolutionary history, and their ecology.
