Amblystegiaceae page

In February 2005, Lars Hedenäs led a very successful taxonomic workshop at Cambridge on the species traditionally considered members of the Amblystegiaceae. Some of his slides dealing with members of this group known to occur in Britain and Ireland can now be viewed as a taxonomic resource for those interested in this group.

The slides should be used in conjunction with a modern treatment of the group such as the second edition of The Moss Flora of Britain and Ireland or Hedenäs, L. (2003) The European species of the Calliergon-Scorpidium-Drepanocladus complex, including some related or similar species. Meylania 28: 1-116 which is a fuller treatment and includes ecological details.

They have been selected to show characters of practical taxonomic value, but there is also a slide showing a summary of some intriguing molecular data suggesting a possible synonomy of the members of the genus Hygroamblystegium. The information is taken from the following paper: Vanderpoorten A. & Jacquemart A.-L., 2004. Evolutionary mode, tempo, and phylogenetic association of continuous morphological traits in the aquatic moss genus Amblystegium. Journal of Evolutionary Biology 17 : 279-287. A pdf file of this paper can be downloaded here.
