Exercise warms adult leatherback turtles
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007Leatherback sea turtles (Dermochelys coriacea) can maintain body temperature (T(B)) up to 18 degrees C above that of the surrounding sea water (T(W)) which allows leatherbacks to enter cold temperate waters and have the largest global range of any reptile.

Pacific leatherback turtles face extinction
Nature, 2000Fisheries can help avert the alarming decline in population of these ancient reptiles. The dwindling numbers of leatherback turtles are signalling a threat to biodiversity in the oceans. A mathematical model based on our assessment of a once-large leatherback population predicts that unsustainable adult mortality, apparently due to human fishing ...

Leatherback Turtles in Vanuatu
Chelonian Conservation and Biology, 2007ABSTRACT Leatherback turtles, Dermochelys coriacea, have not previously been reported nesting in Vanuatu. A review of archival data, unpublished reports, interviews with key informants from coastal communities, and a nesting beach survey indicates that leatherback nesting occurs on a number of islands, including Pentecost, Ambrym, Malakula, Epi, and ...

Population level “flipperedness” in the eastern Pacific leatherback turtle
Behavioural Brain Research, 2010Limb preference is a behavioral indicator of lateralized brain function that was recently elucidated experimentally in lower vertebrates. We assessed natural spontaneous limb use of nesting eastern Pacific leatherback turtles by recording which hindlimb flipper was extended overtop the cloaca to cover the egg chamber during oviposition.

Global phylogeography of the leatherback turtle (Dermochelys coriacea)
Journal of Zoology, 1999AbstractAnalyses of mitochondrial (mt) DNA control region sequences from 175 leatherback turtlesDermochelys coriaceafrom 10 nesting colonies revealed shallow phylogenetic structuring of maternal lineages on a global scale. Eleven haplotypes were observed, and mean estimated sequence divergence,p= 0.00581, is much lower than the deepest nodes reported ...

Field anaesthesia of leatherback sea turtles ( Dermochelys coriacea )
Veterinary Record, 2007Ten nesting leatherback sea turtles on Trinidad were anaesthetised for electroretinogram ( erg ) measurements, using ketamine and medetomidine, reversed with atipamezole. They weighed 242 to 324 kg and were given initial doses of 3 to 8 mg/kg ketamine and 30 to 80 μg/kg medetomidine ...

Interactions Between Leatherback Turtles and Peruvian Artisanal Fisheries
Chelonian Conservation and Biology, 2007ABSTRACT From 1985 to 1999, data were gathered opportunistically on the bycatch of 33 leatherback turtles in coastal Peru, and from 2000 to 2003, a dockside observer program provided data on an additional 133 leatherbacks caught in the coastal gillnet and longline fisheries targeting mahi mahi, sharks, and rays.

Endangered species: where leatherback turtles meet fisheries.
Nature, 2004The dramatic worldwide decline in populations of the leatherback turtle (Dermochelys coriacea) is largely due to the high mortality associated with their interaction with fisheries, so a reduction of this overlap is critical to their survival. The discovery of narrow migration corridors used by the leatherbacks in the Pacific Ocean raised the ...

Leatherback Turtle Deep Dive Optimization Algorithm
This paper proposes an optimization algorithm, called Leatherback Turtle Deep Dive Optimization (LTD-DO), inspired by the unique ecological behavior of leatherback sea turtles. This algorithm simulates the leatherback's behavioral characteristics, including pelagic migration, deep-sea foraging, temperature perception, historical regression, and energy ...openaire +1 more source
