| relationship between organochlorine pesticides and stress indicators in hawksbill sea turtle (eretmochelys imbricata) nesting at punta xen (campeche), southern gulf of mexico. | data on the impact of environmental pollution on the homeostasis of sea turtles remains scarce, particularly in the southern gulf of mexico. as many municipalities along the coastline of the yucatan peninsula do not rely on a waste treatment plant, these organisms could be particularly vulnerable. we searched for relationships between the presence of organochlorine pesticides (ocp) and the level of several oxidative and pollutant stress indicators of the hawksbill sea turtle (eretmochelys imbric ... | 2017 | 28025743 |
| comparison of organochlorine pesticides and pcb residues among hawksbill (eretmochelys imbricata) and green (chelonia mydas) turtles in the yucatan peninsula and their maternal transfer. | organochlorine pesticides and pcb (pops) concentrations were determined in the blood and eggs of green and hawksbill turtles. we compared concentrations between species, analyzed the relationship between turtle size and the pops concentrations and the relationship between the concentrations in the blood of the nesting turtles and their eggs. we expected higher concentrations in the hawksbill turtle because of its higher trophic level, but concentrations were not higher in all the cases. signific ... | 2015 | 25549825 |
