"Few groups of organisms hold such a fascination for evolutionary biologists as the Volvocales.  It is almost as if these algae were designed to exemplify the process of evolution" (Bell 1985)

This project is designed as a common effort among scientists with interests in Volvocales who wish to share information, data, images, publications.  The site provides information about new publications, research themes/projects, labs, databases, and other research tools of interest to the Volvocales community. The website has also sections on Volvocales ecology and life-history, phylogeny, and a wiki (Volvocales wiki).  When available, PDF files of publications are posted. 

If you have information you would like to share, please contact Aurora Nedelcu (www2.unb.ca/vip/amnedelcu/) at anedelcu@unb.ca.
