I maintain this page for use by students in my classes, biology majors, pregraduate and premedical students, and anyone interested in, a) cicada-killer wasps (Crabronidae) and, b) how marine animals control the salt content and volume of their body fluids, an area of comparative animal physiology known as salt and water balance. The page also contains quotations bearing on the nature of science and several links for the interest and amusement of all. It looks best when the viewing window width is set to 18-25.5 cm (7"-10").

The picture to the right is Arcimboldo's Water, painted in 1566. The animals which make up the person are represented so accurately (unusual in a time when whales were often figured with scales and spouting water) that many of them may be identified to genus and species. However, Guiseppi got the eyes wrong on the crab, Cancer pagurus.

• Quotation of the month
• My vita, publications and research interests: the biology of cicada-killer wasps, the comparative physiology of salt and water balance in crustaceans, other invertebrates and fishes, primer on osmosis, and a Na,K-ATPase protocol.
• Links for students in my courses
• Links for Biology majors
• Links for your amusement (jackalopes, Dickinson's poetry and lots more).
• Agassiz and Mani on the study of Nature
• If none of the above are interesting, then take a look at the Monterey Aquarium's live web cams or try the BBC's Hitchhiker's Guide to the Galaxy page.
