Gonadal Morphogenesis under Controlled Temperature in the Sea Turtle Lepidochelys olivacea

Herpetological Monographs, 1989
An electron microscopical and cytochemical investigation of the developing gonads of the Pacific Ridley Lepidochelys olivacea (Eschscholtz) reveals that extragonadal primordial germ cells of this sea turtle follow a migratory pathway similar to that of primordial germ cells in mammalian embryos, i.e., through the yolk sac and hind gut mesentery to the ...

A hematologic and biochemical profile on 3-month-old hatchlings of Lepidochelys olivacea

Comparative Clinical Pathology, 2015
The olive ridley turtle (Lepidochelys olivacea) is globally distributed. However, the species is considered vulnerable. Additionally, hematological and biochemical data for this species are seldom published in the scientific literature. The aim of this study was to gather hematological and biochemical data on young L. olivacea, drawing comparisons with

Biochemical Parameter Analysis of Rescued Olive Ridley Sea Turtles (Lepidochelys olivacea)

Indian Journal of Animal Research, 2020
Background: The olive ridley sea turtle also known as the Pacific ridley sea turtle is a medium-sized species of turtle found in warm and tropical waters, primarily in the Pacific and Indian Oceans. Sea Turtles are an integral part of coastal and marine ecosystems, they have also been fundamental to the culture of coastal societies for millennia.

Nesting ecology of olive ridley (Lepidochelys olivacea) turtles on arribada nesting beaches

2021
Historically, the olive ridley (Lepidochelys olivacea) arribada at Playa Nancite, Costa Rica, was one of the largest arribadas in the eastern Pacific with 70,000 nesting females in a year. Recently that arribada drastically declined. We hypothesized that the decline at Playa Nancite could be due to low hatching success as a result of the high density ...

Comments on the Atlantic Ridley Turtle, Lepidochelys olivacea kempi, in the Chesapeake Bay

Chesapeake Science, 1962
Five specimens of this sea turtle, a species infrequently recorded from Maryland and Virginia estuarine waters, were available for study. Morphometric and meristic data do not vary greatly from published accounts. Blue crabs were found in the stomach contents of one specimen from the Bay.

Primary fibroblast cultures and karyotype analysis for the olive ridley sea turtle (Lepidochelys olivacea)

In Vitro Cellular & Developmental Biology - Animal, 2013
The number of sea turtles in the wild is decreasing because of human activities, such as fishery bycatch (Peckham et al. 2007), oil spills, and marine pollution (Witherington 2001). Furthermore, illegal hunting for their oil, meat, and shells are still continuing (Koch et al. 2013).

The olive ridley sea-turtle (Lepidochelys olivacea) in South-east Africa

Biological Conservation, 1972
Abstract Recent discoveries of the Olive Ridley Sea-turtle ( Lepidochelys olivacea ) in south-east Africa confirm some dubious old records and indicate that there are substantial populations of these sea-turtles off a limited portion of the east African coast and in the coastal waters of Madagascar.

The nesting of the Pacific ridley turtle Lepidochelys olivacea on Playa Nancite, Costa Rica

Marine Biology, 1974
A study of the nesting of the Pacific ridley turtle Lepidochelys olivacea was undertaken in Costa Rica on Playa Nancite — one of two beaches on which the authors had, the previous year, discovered large nesting aggregations of this species. During the 3 1/2-month period of this study, approximately 288,000 turtles nested on the 1300 m-long beach. About

First Documented Record of Nesting by the Olive Ridley Turtle (Lepidochelys olivacea) in Ecuador

Chelonian Conservation and Biology, 2007
ABSTRACT We report on the first confirmed occurrence of Lepidochelys olivacea nesting in Ecuador based on the presence of eggshells and the identification of a late-stage embryo at a beach located in Manta (lat 0.94°S, long 80.7°W), Manabi Province, Ecuador, in October 2004.
