Field anaesthesia of leatherback sea turtles ( Dermochelys coriacea )

Veterinary Record, 2007
Ten 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 ...

Ocular morphology of the Leatherback sea turtle (Dermochelys coriacea)

Veterinary Ophthalmology, 2008
AbstractObjective  The Leatherback sea turtle is the largest extant reptile and the sole member of the family Dermochelyidae. Here, the eye of this critically endangered marine turtle was investigated to determine the anatomy, optics, and optical sensitivity.Animals studied  Three Leatherback sea turtles, Dermochelys coriacea.Results  The eye is small ...

Oxygen Transport in the Leatherback Sea Turtle Dermochelys coriacea

Physiological Zoology, 1990
We have investigated aerobic metabolism and blood O₂ transport properties of the leatherback sea turtle (Dermochelys coriacea). During nesting, at a body temperature of 29° C, resting ventilation (9.2 ± 1. 7 mL min⁻¹ kg⁻¹) and O₂ consumption (0. 25 ± 0.04 mL min⁻¹ kg⁻¹; three turtles) were slightly below values given for other sea turtles. Tidal volume

Canadian waters provide critical foraging habitat for leatherback sea turtles

Biological Conservation, 2006
From 1998–2005, we collected 851 geo-referenced records of leatherback turtles, Dermochelys coriacea, from a volunteer network of commercial fishers and tour boat operators in Atlantic Canada. These data provide new insight into the spatial and temporal distribution of leatherbacks in temperate northwest Atlantic waters. Patterns in sightings data were

Authorship of the Scientific Name of the Leatherback Sea Turtle

Journal of Herpetology, 1986
availability of numerous early taxonomic works, most totally unrelated to those initially involved. Fretey and Bour (1980) first challenged the timehonored authorship of Dermochelys coriacea by Linnaeus (1766) by proposing that Vandelli (1761) was the original author.

MAXIMUM LIKELIHOOD ESTIMATES OF TAG LOSS IN LEATHERBACK SEA TURTLES

Journal of Wildlife Management, 2005
Leatherback sea turtles (Dermochelys coriacea) nesting in French Guiana have been the focus of a long-term monitoring and metal flipper-tagging program and were subjected to a double-tagging experiment starting in 1994. We developed a new method to estimate the rate of tag loss based on the number of days at liberty after tagging, using maximum ...

Oxygen stores and aerobic metabolism in the leatherback sea turtle

Canadian Journal of Zoology, 1992
The leatherback sea turtle, Dermochelys coriacea, is a large, deep-diving species that has a blood oxygen carrying capacity twice that of smaller, shallow-diving sea turtles. In this study we measured lung volume (by argon dilution) and blood volume (by dilution of Evans' blue dye) in leatherbacks to estimate partitioning of oxygen stores and their ...

Salt and water regulation by the leatherback sea turtleDermochelys coriacea

Journal of Experimental Biology, 2002
SUMMARYWe measured the salt and water balance of hatchling leatherback sea turtles, Dermochelys coriacea, during their first few days of life to investigate how they maintain homeostasis under the osmoregulatory challenge of a highly desiccating terrestrial environment and then a hyperosmotic marine environment.
