    • Mangrove Cultures
        We are growing mangroves in order to quantify the hydrogen and carbon isotope fractionation during lipid synthesis across a range of salinities.  This research was motivated by graduate student Nemiah Ladd's observation that hydrogen isotope ratios in lipids from the leaves of the gray mangrove, Avicennia marina, decreased as salinity increased in the Brisbane River (SE Queensland, Australia).  This is opposite the fractionation response observed in phytoplankton, whose lipids are characterized by an increase in their deuterium-to-hydrogen ratio as salinity increases (see our studies from Christmas Island and the Chesapeake Bay).  We would like to quantify this response with controlled experiments  with a variety of mangrove species so that we can calibrate a paleosalinity proxy from mangrove lipids in sediment cores.  These experiments are being performed by graduate student Nemiah Ladd with assistance from UW Biology undergraduate June Landenburger.
        Our first mangroves were planted in our lab in July, 2011 with propagules of Rhizophera apiculata that we collected in Pohnpei, Micronesia.  The figure on the left shows the outside of 3 of the growing tanks, covered with plastic to maintain high humidity.  There is a mock tidal cycle with two high and two low tides per day.  The figure on the right shows the inside of the 15 PSU salinity tank on October 3, 2011.  The largest plants are Rhizophera apiculata.  There are also Rhizophera mangle and Laguncularia racemosa plants growing in this tank, from propagules and seeds from Florida.  If you look closely you can also see some Xylocarpus granatum seeds that have roots, but no shoots yet.  These were collected in Kosrae, Micronesia in September, 2011.

       In order to expand the number of plants and salinities we could maintain, and better control temperature and humidity, we moved our mangrove experiments to the University of Washington Botany Greenhouse in mid-2012.  As of December, 2012 we have 6 species of mangroves growing at 6 different salinities (see below images).
The large number of species are required in order to evaluate the mechanisms responsible for hydrogen isotope fractionation in mangrove lipids as a function of salinity since three different strategies for managing salt are employed by mangroves, alone or in combination.  The images below are from October 11, 2012.  Below left you can see tall shoots of Heritiera littoralis (from Honolulu, HI) and young Rhizophera apiculata (from Pohnpei, FSM) plants.  Below right you can see shoots of Xylocarpus granatum amongst young Rhizophera apiculata plants, both of which were collected in Pohnpei, Micronesia in August 2012.
