Many long-lived marine species exhibit life history traits. that make them more vulnerable to overexploitation. Accurate population trend analysis is essential for development and assessment of management plans for these species. However, because many of these species disperse over large geographic areas, have life stages inaccessible to human surveyors, and/or undergo complex developmental migrations, data on trends in abundance are often available for only one stage of the population, usually…

Population trends and survival of nesting green sea turtles Chelonia mydas on Aves Island, Venezuela

Although these findings support the importance of long-term conservation programs aimed at protecting nesting grounds, they also highlight the need to extend management actions to foraging grounds where human activities may still impact green turtle populations.

Long-term growth and survival dynamics of green turtles (Chelonia mydas) at an isolated tropical archipelago in Brazil

Slow growth and stable stocking numbers may be suggestive of density-dependent regulation having taken place following initial population recovery that occurred prior to the current study.

Long-term growth and survival dynamics of green turtles (Chelonia mydas) at an isolated tropical archipelago in Brazil

For effective management of species of conservation concern, knowledge of life history parameters is essential. Here, we present the results of one of the longest ongoing capture-mark-recapture

Survival probability of immature green turtles in two foraging grounds at Culebra, Puerto Rico

This is the first study on the survival of green turtles in the West Indies and employs the Cormack-Jolly-Seber model to estimate the survival probabilities of green Turtles in 2 neritic bays at Culebra municipality, Puerto Rico.

Trophic ecology of a green turtle breeding population

Stable isotope analysis is used to investigate the trophic ecology and spatial distribution of foraging green turtles in the Greater Caribbean and explores the possibility that adult green turtles, originally considered to be herbivores, may, like their counterparts in the Pacific Ocean, display carnivorous feeding strategies.

Population Status of Green Turtles (Chelonia mydas) Foraging in Arica Bay, Chile1

The consistent presence of turtles between 2012 and 2016 and the relatively high abundance compared to the general situation reported for the species in Chile makes Arica Bay the most important feeding congregation of green turtles in the country.

Trends in fishery-dependent captures of sea turtles in a western North Atlantic foraging region

Accurate assessments of sea turtle populations are essential for determining population trends and formulating conservation plans for the recovery of these imperiled species. Although counting

Ecology and Conservation of Marine Turtles in a Central Pacific Foraging Ground

This study represents the first data and discussion on marine turtle distribution, abundance, and health at a marine turtle foraging ground in the central Pacific, Palmyra Atoll National Wildlife Refuge, which constitutes a regionally important mixed-size-class foragingGround for green turtles and hawksbill turtles.

Genetic composition and origin of juvenile green turtles foraging at Culebra, Puerto Rico, as revealed by mtDNA

This study addresses the information gap on the connectivity of the green turtle in the North Atlantic, and establishes an important baseline that can be used to determine future changes in stock composition.



Survival probability estimates for immature green turtles Chelonia mydas in the Bahamas

This study reports the first application of the joint analysis of live-recapture and dead-recovery data to sea turtle populations and demonstrates the advantages of this modeling approach.

Genetic composition of a green turtle (Chelonia mydas) feeding ground population: evidence for multiple origins

Evidence from genetic markers, haplotype frequencies, and maximum likelihood analyses are concordant in indicating that multiple colonies contribute to the Bahamian FG population, which supports a life-cycle model in which individuals become pooled in post-hatchling and juvenile habitats as a consequence of ocean currents and movement among FGs.


The carrying capacity of pastures of the seagrass Thalassia testudinum, the major diet plant of the green turtle, is estimated to serve as a baseline to estimate changes in green turtle populations in the Caribbean since pre- Columbian times and to set a goal for recovery for these depleted populations.

Trophic status drives interannual variability in nesting numbers of marine turtles

It is suggested that green turtles are herbivorous, feeding on sea grasses and macro–algae, and this primary production will be more tightly coupled with prevailing environmental conditions than the carnivorous diet of the loggerhead turtle.

Twenty‐Six Years of Green Turtle Nesting at Tortuguero, Costa Rica: An Encouraging Trend

The green turtle (Chelonia mydas) population that nests at Tortuguero, Costa Rica, is the largest in the Atlantic by at least an order of magnitude. Surveys to monitor the nesting activity on the

Origins of green turtle (Chelonia mydas) feeding aggregations around Barbados, West Indies

The data suggest that the similar-sized green turtles sampled on the Barbados FG are a mixed stock of more diverse origins than any previously sampled feeding aggregations in the Caribbean region, and support a life cycle model that incorporates a tendency of immatures to migrate from their initial foraging Grounds at settlement towards suitable foraging grounds closer to their natal rookeries as they mature.
