Introduction
Adriana Cortés currently works at the Laboratoire d'Ecologie, Systématique et Evolution , Université Paris-Sud 11. Adriana does research in Toxicology and Veterinary Medicine. Her current project is 'Inorganic elements in marine turtles (Lepidochelys olivacea) from “La Escobilla” beach (Mexico) and biomarkers related to metal pollutants.'

Article
Full-text available
One recurring difficulty in ecotoxicological studies is that a substantial portion of concentrations are below the limits of detection established by analytical laboratories. This results in censored distributions in which concentrations of some samples are only known to be below a threshold. The currently available methods have several limitations...
Article
Full-text available
We are pleased to have contributed to the newly released State of the World’s Sea Turtles (SWOT) Report, vol. XVII
Article
Full-text available
In marine turtles, sex is determined during a precise period during incubation: males are produced at lower temperatures and females at higher temperatures, a phenomenon called temperature-dependent sex determination. Nest temperature depends on many factors, including solar radiation. Albedo is the measure of the proportion of reflected solar radi...
Article
Full-text available
Several sightings of different pinniped species have been recorded outside their typical areas of distribution. In May 2019, pinniped yearlings were sighted on 4 occasions on the central coast of Oaxaca, Mexico. One of them was found injured in La Escobilla (Oaxaca, Mexico) and was transported immediately to the Centro Mexicano de la Tortuga for re...
Preprint
Sea turtles are marine species that are generally in danger of extinction. The conservation strategies in the different countries are attempting to preserve these species and should be constantly updating their policies according to research results taking place on site. The most abundant and frequent species of sea turtle that nest in the Pacific...
Article
This study reports the largest inorganic elements database in the blood of live marine turtles (Lepidochelys olivacea), with 241 live as well as 38 dead nesting turtles sampled and analyzed for 26 inorganic elements, including essential (Al, As, B, Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Se, S, V, and Zn) and non-essential elements (Cd, Li, P...
Article
Full-text available
A hundred nesting olive ridley turtles were sampled to determine biochemical parameters (ALP, AST, ALT, creatinine, albumin, cholesterol, glucose, proteins, triglycerides, urea, and P-nitrophenyl acetate esterase activity). Esterase activity (EA) is a new biomarker very sensitive to metals. Most of the samples showed detectable levels. We also anal...
Article
Full-text available
The aim of this study was to determine p-nitrophenyl acetate esterase activity (EA) and cortisol concentrations in serum of marine Olive Ridley turtles (Lepidochelys olivacea) from a Mexican Pacific population (La Escobilla beach) and to evaluate the possible relation of metal and metalloids with these biomarkers. EA, cortisol and selected chemical...
Article
The Olive Ridley marine turtle (Lepidochelys olivacea) is characterized by individual morphological variability in the number and shape of scutes. The influence of pollutants on developmental instability and one of its consequences, the asymmetry of individuals, has been demonstrated in several species, especially invertebrates and some birds. Howe...
Article
Due to their longevity and extensive migration areas, marine turtles are able to accumulate diverse contaminants over many years and as a consequence they represent an interesting bioindicator species for marine ecosystem pollution. Metals provoke toxicological effects in many aquatic animal species, but marine turtles have been under-investigated...
Article
Full-text available
Due to their bioaccumulation and biomagnification pathways, inorganic elements can accumulate in high-level aquatic organisms in the food web. Then, this species can be used to monitor the quality of the environment. Blood concentration of nine inorganic elements, including possible toxic metals (An, Cu, Mn, Se, As, Ni, Cd, Pb, and Hg), in 20 males...
Thesis
Full-text available
Long-lived marine species such as marine turtles are becoming an important tool in ecotoxicology because of their sensitivity to marine environmental change, especially regarding pollution. They usually occupy diverse trophic levels in the marine food web (depending on the age and species), and can therefore accumulate different pollutants over the...
Article
Inorganic elements (Pb, Cd, Hg, Al, As, Cr, Cu, Fe, Mn, Ni, Se and Zn) are present globally in aquatic systems and their potential transfer to marine turtles can be a serious threat to their health status. The environmental fate of these contaminants may be traced by the analysis of turtle tissues. Loggerhead turtles (Caretta caretta) are the most...
Article
Lepidochelys olivacea is the most abundant and globally distributed sea turtle species in the world and thus, monitoring this species for persistent organic pollutants, such as perfluorinated chemicals, is fundamental for their protection. This study was the first to evaluate the occurrence of five PFCAs (PFOA, PFNA, PFDA, PFUnA, PFDoA) in liver an...
Conference Paper
The IUCN Red List classifies Olive Ridley turtles (Lepidochelys olivacea) as “vulnerable”. In Mexico, all marine turtles are considered endangered species within the regulation norm NOM-ECOL-059-2010 and have been made a priority for conservation. One of the main treats that have lead turtle to this point is pollution; among them trace elements, es...

Serum biochemistry is commonly used as a diagnostic technique to assess health in wild and domestic animals. These parameters can vary depending on species, gender, age, diet, pathological process and analysis techniques. Due to all these variations is not easy to establish normal parameters in marine turtles and it is recommended to have a databas...

Esterases (EA), such as paraoxonase, are widely studied enzymes due to their multifunctional roles in diverse biochemical pathways such as protection against oxidative damage and lipid peroxidation, contribution to innate immunity, detoxification of reactive molecules, modulation of endoplasmic reticulum stress and regulation of cell proliferation/...

Pb and Cd are the two most studied heavy metals in environmental biomonitoring due to their high toxicity potential. Successive studies can show if the bioavailability of these metals varies with time, and thus evaluate the toxicological risk to which marine turtles are subjected. In the present study we have analyzed blood, liver and kidney sample...
