Social behavior

One of my long-term interests is social behavior, with two main study species:  a facultatively group-living spider in California, Holocnemus pluchei, and a social spider in Mexico, Metepeira incrassata, studied in collaboration with George Uetz.  Here are some relevant publications (undergraduate co-authors are underlined).

Prospective students please note:  I am not actively pursuing this research now, although I would be pleased to have a student who has his or her own fellowship funding and is interested in this topic.
