Physiological ecology of development in organisms that reproduce and develop on tidal flats
I am studying the physiological ecology of development in organisms that reproduce and develop on tidal flats. Pictured is the bubble snail Melanochlamys diomedea, including an adult (black), an egg mass (cream) with long sand-mucous tether (pink arrow points to end of tether), and embryos embedded in gel (inset) in a tide pool at False Bay on San Juan Island, WA. Development temperatures fluctuate widely and rapidly during tidal exchanges, reaching levels that regularly induce the synthesis of heat shock proteins (HSP-70 and -90). I am integrating lab and field information on cellular defense mechanisms, developmental performance, and reproductive timing to understand how processes at the embryonic and adult stages interact to determine spatial and temporal variation in fitness.
