چکیده
Leatherback turtle (Dermochelys coriacea) is highly impacted by fisheries’ bycatch worldwide. This study updates and estimates the leatherback stranding records from 2001 to 2014 in Gulf of Venezuela. Eighty-six stranded turtles were documented coast Immature most affected (85.1%) highest number strandings recorded during dry season (55.8%). Our findings represent minimum estimate events for Venezuela, especially considering current lack fisheries regulations. latest update Venezuela could help create new management solutions area aiming minimize impact on populations Caribbean.

Endocrine responses to diverse stressors of capture, entanglement and stranding in leatherback turtles (Dermochelys coriacea)
Leatherback turtles (Dermochelys coriacea) are exposed to many anthropogenic stressors, yet almost no data on stress physiology exist for this species. As a first step toward understanding the physiological responses of leatherback turtles to stress, and with the particular goal of assessment of the effect of capture, we quantified corticosterone (an adrenal stress hormone) and thyroxine (a reg...
متن کاملPre-nesting Movements of Leatherback Sea Turtles, Dermochelys coriacea, in the Western Atlantic
Understanding high-use areas for highly migratory species and their movements within these areas may provide insight into behaviors such as foraging and mating. In the Western Atlantic, the leatherback sea turtle, Dermochelys coriacea, has a broad geographic range extending from nesting beaches at low latitudes to foraging areas off the coast of Eastern Canada. Biotelemetry has revealed much ab...
متن کاملThe role of infrequent and extraordinary deep dives in leatherback turtles (Dermochelys coriacea).
Infrequent and exceptional behaviours can provide insight into the ecology and physiology of a particular species. Here we examined extraordinarily deep (300-1250 m) and protracted (>1h) dives made by critically endangered leatherback turtles (Dermochelys coriacea) in the context of three previously suggested hypotheses: predator evasion, thermoregulation and exploration for gelatinous prey. Da...
متن کاملGenetic diversity and origin of leatherback turtles (Dermochelys coriacea) from the Brazilian coast.
The leatherback sea turtle (Dermochelys coriacea) population that nests in Brazil is restricted to a few individuals, but high densities of pelagic individuals are observed along the southern and southeastern Brazilian coast. We investigated the diversity of the mitochondrial DNA (mtDNA) control region in order to understand the relationship between nesting and pelagic leatherbacks from Brazil ...
متن کاملBiotic and abiotic factors affect the nest environment of embryonic leatherback turtles, Dermochelys coriacea.
Clutches of leatherback turtles, Dermochelys coriacea, have lower hatching success than those of other sea turtles, but causes of high embryonic mortality are unknown. We measured characteristics of clutches along with spatial and temporal changes in PO(2) and temperature during incubation to determine the extent to which they affected the developmental environment of leatherback embryos. Minim...
