Title Hydrogen isotope response to changing salinity and rainfall in Australian mangroves
Language English
Document Type Article
Author Keywords leaf waxes; paleoclimate; taraxerol; water relations
Abstract Hydrogen isotope ratios (H-2/H-1, delta H-2) of leaf waxes covary with those in precipitation and are therefore a useful paleohydrologic proxy. Mangroves are an exception to this relationship because their delta H-2 values are also influenced by salinity. The mechanisms underlying this response were investigated by measuring leaf lipid delta H-2 and leaf and xylem water delta H-2 and delta O-18 values from three mangrove species over 9.5 months in a subtropical Australian estuary. Net H-2/H-1 fractionation between surface water and leaf lipids decreased by 0.5-1.0% ppt-1 for n-alkanes and 0.4-0.8% ppt-1 for isoprenoids. Xylem water was H-2 depleted relative to surface water, reflecting H-2 discrimination of 4-10% during water uptake at all salinities and opportunistic uptake of freshwater at high salinity. However, leaf water H-2 enrichment relative to estuary water was insensitive to salinity and identical for all species. Therefore, variations in leaf and xylem water delta H-2 values cannot explain the salinity-dependent H-2 depletion in leaf lipids, nor the 30 parts per thousand range in leaf lipid delta H-2 values among species. Biochemical changes in direct response to salt stress, such as increased compatible solute production or preferential use of stored carbohydrates, and/or the timing of lipid production and subsequent turnover rates, are more likely causes.

Funding Text This research was funded by NSF grant no. EAR-1348396 (J.P.S.), a University of Washington Royalty Research Fund grant (J.P.S.) and an NSF Graduate Research Fellowship (N.L.). Bradley Eyre and Southern Cross University hosted J.P.S. during a sabbatical so the sampling of mangroves for this study could be accomplished. Amy Duncan assisted with the fieldwork. Ariel Townsend and Josh Gregersen assisted with sample preparation and instrument maintenance. We had productive conversations with Dan Nelson, Ashley Maloney, Ansgar Kahmen, Paul Quay, Anitra Ingalls, Ruth Reef and Liz van Volkenberg that improved our experimental design and data analysis. Ansgar Kahmen was generous in the use of his lab for leaf and xylem water extractions and TCEA measurements. Dan Nelson and Oliver Rach measured leaf and xylem water isotopes at the University of Basel. Two anonymous reviewers provided insightful comments that helped improve this manuscript. We are grateful for all of their contributions.
