Historical Overfishing and the Recent Collapse of Coastal Ecosystems
Ecological extinction caused by overfishing precedes all other pervasive human disturbance to coastal ecosystems, including pollution, degradation of water quality, and anthropogenic climate change.…
Global Trajectories of the Long-Term Decline of Coral Reef Ecosystems
Records are compiled, extending back thousands of years, of the status and trends of seven major guilds of carnivores, herbivores, and architectural species from 14 regions that indicate reefs will not survive without immediate protection from human exploitation over large spatial scales.
Research and Management Techniques for the Conservation of Sea Turtles
Nutrition and grazing behavior of the green turtle Chelonia mydas
- K. Bjorndal
- 1 July 1980
Green turtles consumed a more digestible forage-higher in protein and lower in lignin-than the ungrazed, older leaves of T. testudinum, and the selectivity of green turtles for either a seagrass or algal diet may reflect the specificity of their intestinal microflora.
Phylogeography and population structure of the Atlantic and Mediterranean green turtle Chelonia mydas: a mitochondrial DNA control region sequence assessment
- S. Encalada, P. N. Lahanas, K. Bjorndal, A. Bolten, M. Miyamoto, B. Bowen
- Biology, Environmental ScienceMolecular Ecology
- 1 August 1996
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.
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.
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…
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.
Relation of Temperature, Moisture, Salinity, and Slope to Nest Site Selection in Loggerhead Sea Turtles
The results refute the current hypothesis that an abrupt increase in temperature is used by loggerheads as a cue for excavating a nest, and assesses the role of microhabitat cues in nest site selection in Loggerhead Sea Turtles.
