The sequence data provide higher resolution both in terms of the number of mtDNA genotype variants and the phylogeographic relationships detected within the Atlantic region, and reveal a gene genealogy that distinguishes two groups of haplotypes corresponding to the western Caribbean and Mediterranean, and (ii) eastern Caribbean, South Atlantic and West Africa.
BLOOD PROFILES FOR A WILD POPULATION OF GREEN TURTLES (CHELONIA MYDAS) IN THE SOUTHERN BAHAMAS: SIZE-SPECIFIC AND SEX-SPECIFIC RELATIONSHIPS
Blood biochemical profiles and packed cell volumes were determined for 100 juvenile green turtles, Chelonia mydas, from a wild population in the southern Bahamas. There was a significant correlation…
GREEN TURTLE SOMATIC GROWTH MODEL: EVIDENCE FOR DENSITY DEPENDENCE
The carrying capacity of pastures of the seagrass Thalassia testudinum, the major diet plant of the green turtle, is estimated to serve as a baseline to estimate changes in green turtle populations in the Caribbean since pre- Columbian times and to set a goal for recovery for these depleted populations.
Somatic growth model of juvenile loggerhead sea turtles Caretta caretta: duration of pelagic stage
A growth model and estimates for duration of the pelagic juvenile stage for loggerhead sea turtles Caretta caretta in the North Atlantic based on length-frequency analyses and sizes of young-of-the-year stranded in the Azores are presented.
Techniques for Measuring Sea Turtles
Sea turtles are measured on foraging grounds to determine frequency of size classes of turtles present as well as to monitor growth rates, which can indicate habitat quality and physiological status.
TRANSATLANTIC DEVELOPMENTAL MIGRATIONS OF LOGGERHEAD SEA TURTLES DEMONSTRATED BY mtDNA SEQUENCE ANALYSIS
Molecular markers based on mitochondrial (mt) DNA control region sequences were used to test the hypothesis that juvenile loggerhead sea turtles (Caretta caretta) in pelagic habitats of the eastern…
Population structure of loggerhead turtle (Carettacaretta) nesting colonies in the Atlantic and Mediterranean as inferred from mitochondrial DNA control region sequences
The relationships among observed haplotypes suggest a biogeographic scenario defined by climate, natal homing, and rare dispersal events in the western Atlantic region, which prompts a reconsideration of management strategies for nesting populations and corresponding habitats in this region.
Regional Management Units for Marine Turtles: A Novel Framework for Prioritizing Conservation and Research across Multiple Scales
The nested envelope models, or Regional Management Units (RMUs), are a solution to the challenge of how to organize marine turtles into units of protection above the level of nesting populations, but below thelevel of species, within regional entities that might be on independent evolutionary trajectories.
Global Conservation Priorities for Marine Turtles
A new assessment framework was developed that allowed to evaluate, compare and organize marine turtle RMUs according to status and threats criteria, and should serve as a model for conservation status assessments and priority-setting for widespread, long-lived taxa.
