"The present report is a summary and preliminary analysis of data on the green turtle, Chelonia mydas, that has been collected during a 22-year tagging program at Tortuguero, Costa Rica, 52 miles north of the Caribbean city of Puerto Limon. [...] Key Result Smaller numbers of recoveries cluster in Colombia, Panama, and Mexico.Expand
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 theExpand
Some Problems of Sea Turtle Ecology
An apparent dichotomy in the "lost-year" ecology of the Tortuguero green turtles and Kemp's ridley is suggested and possible causes of one-season nesting and its bearing on sea turtle demography are discussed. Expand
The Ecology and Migrations of Sea Turtles 8. Tests of the Developmental Habitat Hypothesis
The studies in Panama and Bermuda reported in this paper use netting, mark/recapture, laparoscopy, and satellite telemetry to investigate size distributions, maturity status, residency, site fidelity, and developmental migrations of three species of sea turtles at three study sites. Expand
The spatio-temporal distribution and population structure of green turtles (Chelonia mydas) in New Zealand
A baseline understanding of the ecology of green turtles at the edge of their range is provided, providing opportunities to investigate regional niche modelling and connectivity of this highly mobile species, while also monitoring broad-scale effects of climate-induced environmental change. Expand
Marine turtle nesting and conservation needs on the south-east coast of Nicaragua
The goal of this study was to quantify marine turtle nesting activity by species, identify threats to their populations, and provide recommendations for their conservation on the south-east coast ofExpand
The Feeding Ecology of the West Caribbean Green Turtle (Chelonia mydas ) in Nicaragu a
The stomach contents of 243 subadult and adult green turtles, Chelonia mydas, taken at their foraging grounds off the eastern coast of Nicaragua, were examined and it was postulated that conditions on the foraging pastures may determine the timing of the reproductive cycles. Expand
Laying on the edge: demography of green sea turtles (Chelonia mydas) nesting on Playa Norte, Tortuguero, Costa Rica
The results presented here concur with results from studies of nesting females at TNP and highlight the importance of Playa Norte as a nesting ground for Atlantic green turtles. Expand
Migration of green turtles Chelonia mydas from Tortuguero, Costa Rica
The proximity of foraging grounds to the nesting beach (mean 512 km) may permit female turtles to invest more energy in reproduction and hence the Tortuguero population may have greater potential for recovery than other green turtle nesting populations. Expand
An Assessment of the Sea Turtles and Their Marine and Terrestrial Habitats at Saipan, Commonwealth of the Northern Mariana Islands
An estimated 169 individual Chelonia mydas were observed via 238 sightings over 28 marine surveys covering roughly 54% of Saipan’s outer reef and shoreline perimeter. No other sea turtle species wereExpand
Population structure and demographic history of green turtle (Chelonia mydas) in the West Atlantic
Sea turtles are reptiles with a long lifespan that undertake wide-ranging migrations through feeding and nesting sites, resulting in successive stages of mixing and isolating genetic stocks, bothExpand


Green turtle migrations in the Hawaiian archipelago
Abstract In order to understand better the natural history and conservation status of the unique land-basking Hawaiian green turtle population ( Chelonia sp.), intensive tagging studies wereExpand
Observations on Sea Turtles at Aldabra Atoll
The majority of the work was carried out on adult green turtles which had been harpooned and captured by the Seychellois turtlemen at Aldabra, and certain colour characteristics are strongly correlated with sex; a predictive index for sex determination is presented. Expand
Modulated Reproductive Periodicity in Chelonia
After 15 yr tagging at the nesting ground of Chelonia mydas at Tortuguero, Costa Rica, 447 remigration returns have been recorded. These confirm previous indications that some Tortuguero femalesExpand
Sea turtles nesting in Surinam
This book contains sections on general taxonomy and on the biology of sea turtles, subjects which have been treated elsewhere in a superior way by more competent authors. Expand
Energetics of swimming of a sea turtle.

Based upon the drag calculations for young turtles, it is estimated that adult turtles making the round-trip breeding migration between Brazil and Ascension Island would require the equivalent of about 21% of their body mass in fat stores to account for the energetic cost of swimming. Expand
Hunting and Fishing Focus Among the Miskito Indians, Eastern Nicaragua
The amounts of native animals taken in hunting and fishing by Amerind peoples are almost unknown. The interrelationships of cultural and ecological systems determine to a large extent hunting andExpand
Revision of the African tortoises and turtles of the suborder Cryptodirac by Arthur Loveridge and Ernest Ep Williams
Revision of the African tortoises and turtles of the suborder Cryptodira, Revision of the European tortoise and turtle suborder cryptodira is presented. Expand
Oxygen diffusion across a sea turtle (Chelonia mydas) egg shell
Abstract 1. 1. The egg shell and outer membrane of the turtle egg have a mean diffusion coefficient K of 6·59 × 10−6 cm3 STP sec−1 cm−2 mm Hg−1. 2. 2. This coefficient is approximately twice that ofExpand
