The diving behavior of green turtles at Ascension Island
Article Abstract:
Time-depth recorders were used to examined the diving behavior of green turtles. They reached depths of 18-20 m on resting dives and duration rose significantly with deeper dives. It is estimated that the oxygen consumption during resting dives for two turtles was 0.016 and 0.020 litres O(sub2)/kg per hour respectively.

Nest placement by loggerhead turtles, Caretta caretta
Article Abstract:
The nest placement behavior of loggerhead turtles (Caretta caretta) is analyzed. Female turtles lay their eggsaway from the sea, but not in vegetation that backed the beach. Moreover, hatchling success increases significantly for nests laid further from the sea. Thermal cues in the sand initiate digging, since sand temperatures are higher further from the sea. Lastly, the implications of nest placement for hatchling sex ratio are presented.

Effect of tagging marine turtles on nesting behaviour and reproductive success
Article Abstract:
Green Chelonia mydas and loggerhead Caretta caretta turtles were studied to find the effects of flipper tagging on postovipositional behaviour and reproductive success. Loggerheads stopped covering eggs on 12 occasions when tagging was undertaken immediately after oviposition, although green turtles did not abandon nesting. The speed of descent to the sea was no different between tagged and untagged turtles.
