Assessments Of Surface-Pelagic Drift Communities And Behavior Of Early Juvenile Sea Turtles In The Northern Gulf Of Mexico, Robert F. Hardy
Assessments Of Surface-Pelagic Drift Communities And Behavior Of Early Juvenile Sea Turtles In The Northern Gulf Of Mexico, Robert F. Hardy
USF Tampa Graduate Theses and Dissertations
Knowledge of species distribution and habitat associations are essential for conservation measures. Such information is lacking for many marine species due to their occupancy of broad and ephemeral habitats that are difficult to access for study. Sea turtles, specifically the surface-pelagic juvenile stage of some species, are a group for which significant knowledge gaps remain surrounding their distribution and habitat use. Recent research has confirmed the long-standing hypothesis that the surface-pelagic juvenile stage occurs within surface-pelagic drift communities (SPDC). Within the North Atlantic and surrounding basins, the holopelagic macroalgae Sargassum spp. dominates SPDC and serves as a remotely-detectable indicator of …
Spatio-Temporal Analysis Of Chilling Events In Mangrove Forests Of South Florida, Bina Thapa
Spatio-Temporal Analysis Of Chilling Events In Mangrove Forests Of South Florida, Bina Thapa
FIU Electronic Theses and Dissertations
Chilling events are infrequent but important disturbances in subtropical Florida. When temperatures drop to near freezing, significant mortality often accrues in mangrove forests. Chilling events play a role in maintaining structural diversity in mangrove forests, and in limiting mangrove poleward distribution. I examined the spatio-temporal distribution of chilling events in mangrove forests of southern Biscayne Bay by using Landsat TM5 images since 1989. Damage was usually confined to dwarf mangrove forest, especially when chilling temperatures were moderate and short in duration. However, damage from extended and severe freezes such as in January 2010 impacted larger trees as well. Recovery is …
