Satellite tracking reveals unusual diving characteristics for a marine reptile, the olive ridley turtle Lepidochelys olivacea
The movements, diving behaviour and thermal environment occupied by 4 adult female olive ridley turtles Lepidochelys olivacea in northern Australia were determined through satellite telemetry. Patterns of behaviour recorded were rather unusual compared to other sea turtles in that dives were mainly deep, largely benthic and exceptionally long (>2 h) in some cases, characteristics typical of ove...
متن کاملTiming of SOX9 downregulation and female sex determination in gonads of the sea turtle Lepidochelys olivacea.
The SRY-related gene SOX9 is involved in the differentiation of Sertoli cells in male gonads of vertebrates with different kinds of sex determination. In the olive ridley Lepidochelys olivacea, a species with temperature sex determination (TSD), the SOX9 protein is expressed at stages 21-24 in medullary cells in gonads of embryos incubated at both male-(MPT) or female-promoting temperatures (FP...
متن کاملDistribution and Feeding Behavior of Omorgus suberosus (Coleoptera: Trogidae) in Lepidochelys olivacea Turtle Nests
Omorgus suberosus (Fabricius, 1775) has been identified as a potential predator of the eggs of the turtle Lepidochelys olivacea (Eschscholtz, 1829) on one of the main turtle nesting beaches in the world, La Escobilla in Oaxaca, Mexico. This study presents an analysis of the spatio-temporal distribution of the beetle on this beach (in areas of high and low density of L. olivacea nests over two a...
متن کاملDifferential expression of SOX9 in gonads of the sea turtle Lepidochelys olivacea at male- or female-promoting temperatures.
In mouse and chick embryos, the SOX9 gene is down-regulated in genetic females whereas in genetic males it remains in the Sertoli cells. We studied the distribution of SOX9 protein in developing genital ridges of embryos of the sea turtle Lepidochelys olivacea incubated at male- or female-promoting temperatures, using the antibody for detection. At stages 22-24, cells in medullary cords show SO...
متن کاملLack of xenoestrogen-induced vitellogenin in male olive ridley sea turtles (Lepidochelys olivacea) from the Pacific coast of Costa Rica
Olive ridley sea turtles (Lepidochelys olivacea) distribute widely throughout Eastern Pacific (EP) waters. During reproduction these animals aggregate near coastal waters where they may be exposed to industrial or agrochemical environmental pollutants that may disrupt the endocrine system of these reptiles. One group of compounds of concern is the persistent organic pollutants (POPs), some of w...
