  1. Hurricane-Related Research at FCE Bill Anderson, FIU Edward Castaneda, LSU Steve Davis, TAMU Vic Engle, ENP Evelyn Gaiser, FIU Hugh Gladwin, FIU Victor Rivera-Monroy, LSU Carrie Rebenack, FIU Robert Twilley, LSU

  2. LSU group • Sediment deposition • Mangrove production • Gap modeling Engle/Fuentes Flux tower Urban ecol. group - Effects of disturbance on economics, demography • Steve Davis et al. • Creek fluxes of nutrients • Sediment deposition • Mangrove production • Bill Anderson • Dendrochronology on • Big Pine Key LIDAR transects

  3. FCE Central Questions • How is the location and the spatial extent of the oligohaline ecotone controlled by changes in climate, fresh water inflow, and disturbance? • How do hurricane impacts control mangrove forest structure, productivity and river constituent discharge? • What is the rate of recovery of mangroves after hurricanes? • Do hurricanes elicit stable state changes similarly in urban and natural landscapes? • Teleconnections? Climate and Diversity Mean annual air temperature: 24ºC Mean annual precipitation: 1135 to 1515 mm (60% wet season) Mean evapotranspiration: 1800 mm Diversity:L. racemosa, C. erectus, R. mangle, and A. germinans. R. mangle, C. jamaicense (ecotone) SRS: 2500-7000 stems/ha TS: 700 stems/ha

  4. Trajectory and wind speed at landfall for hurricane Wilma in October 2005 Trajectory of hurricane Wilma during October 2005 Wind speed associated with October 2005

  5. Ecosystem response to hurricane Wilma November 2006 March 2007

  6. Big Pine KeyDendrochronology • 13C and 18O • 3-yr resolution of whole rings • The first order trend in carbon indicates that this site was not affect by SL rise, but Hurr. Wilma. • Trees now dead
