Overwintering behaviour in sea turtles: dormancy is optional
Thirteen loggerhead turtles Caretta caretta were released (10 from Naples, Italy, 2 from Monastir, Tunisia, 1 from Gallipoli, South Italy) with satellite relay data loggers (SRDL) to elucidate theirExpand
Reptilian diving: highly variable dive patterns in the green turtle Chelonia mydas
Green turtles Chelonia mydas nesting on Cyprus were equipped with multi-channel data loggers monitoring diving behaviour and activity (via a logger-integrated 3-D compass which served as an activity sensor) during the inter-nesting interval, revealing high activity levels attributed to extensive foraging. Expand
First records of dive durations for a hibernating sea turtle
New satellite relay data loggers are used to obtain the first records of up to 7 h long dives of a loggerhead turtle (Caretta caretta) overwintering in Greek waters, suggesting that the common belief that sea turtles hibernate underwater, as some freshwater turtles do, is incorrect. Expand
Long‐Term Cold Acclimation Leads to High Q10 Effects on Oxygen Consumption of Loggerhead Sea Turtles Caretta caretta
There was a significant positive correlation between the proportion of a day spent actively swimming and V̇o2 and the metabolic responses were positively correlated with changes in Tw, but this time the corresponding Q10 was only 1.3. Expand
Why we mind sea turtles' underwater business: A review on the study of diving behavior
This review of studies on sea turtle diving behavior highlights the needs for some level of minimum standardization, especially for studies involving electronic telemetry equipment, in addition to clarifying where future effort should be focused. Expand
Allometric scaling of lung volume and its consequences for marine turtle diving performance.
The results provide a reference point for calculating oxygen storage capacities and air volumes available for buoyancy control and demonstrate that diving capacities of marine turtles were potentially over-estimated when the V(L)-body mass effect was not considered. Expand
Diving behaviour of green turtles: dive depth, dive duration and activity levels
Time-depth recorders and activity recorders used to examine diving behaviour and activity of green turtles during their internesting period at Cyprus found Turtles were found to spend a large propor-tion of time undertaking dives with a characteristic ‘U-shaped’ profile. Expand
Loggerhead turtles nesting in Libya: an important management unit for the Mediterranean stock
Libya is one of the most important loggerhead turtle Caretta caretta nesting grounds in the Mediterranean Sea, but data on its genetic diversity and demographic connection to adjacent MediterraneanExpand
The relationship between loggerhead turtle (Caretta caretta) movement patterns and Mediterranean currents
Observations show that neritic stage loggerhead turtles conduct migration in two distinct alternate phases: the first characterized by high and constant speed of travel both when swimming with or against currents and the second typified by low travel speeds and a good concurrence between the trailed routes and the course of the currents.

When surfacers do not dive: multiple significance of extended surface times in marine turtles
This is the first evidence that loggerhead turtles may refrain from diving for at least two reasons, either to absorb solar radiation or to recover from anaerobic activity. Expand
