Last night I attended a talk in Lisbon given by Ward Wheeler at the AMNH in New York City and moderated by Frederick Matsen from his home institution in Berkeley, California. The talk was the second on a series of talks in phylogenetics held via videoconferencing.

The idea behind phyloseminar.org is to hold regular live online seminars in phylogenetic methodology open to anyone around the globe. This is a challenge given the time zone differences of the possible participants, but it does makes the whole event fun: I watched it after dinner at 9:00pm; the presenter gave it at his 4:00pm; while the moderator was there after lunch at his 1:00pm.

In the latest issue of the Proceedings of the National Academy of Sciences (USA), Blackledge and coworkers assembled a comprehensive data set for cladistic analysis of orb web spiders that includes six different molecular loci, 143 morphological characters and behavior in the form of characters derived from web architecture.
