Nesting of green turtles (Chelonia mydas) at Ascension Island, South Atlantic
Abstract A detailed survey of the nesting by green turtles ( Chelonia mydas ) on Ascension Island (7°57′ S, 14°22′ W) was conducted between 1 December 1998 and 1 October 1999. During this periodExpand
Green turtle nesting on Trindade Island, Brazil: abundance, trends, and biometrics
Green turtles Chelonia mydas nesting at Trindade Island, 1140 km off the coast of Brazil, were monitored discontinuously from 1982/83 to 2008/09. For 7 years during this period, the majority ofExpand
Migration of green (Chelonia mydas) and loggerhead (Caretta caretta) turtles to and from eastern Australian rookeries
Feeding-ground captures of green and loggerhead turtles tagged while nesting at eastern Australian rookeries over a 21-year period are summarised and migratory behaviour, imprinting and navigation are discussed. Expand
The Influence of Beach Sand Characteristics on the Nesting Behavior and Clutch Survival of Green Turtles (Chelonia mydas)
The thermal sensitivity of sprint speed in Anolis lizards and the effect of temperature on jump performance of the frog Limnodynastes tasmaniensis is studied. Expand
The interplay of homing and dispersal in green turtles: a focus on the southwestern atlantic.
Impacts of population size, geographic distance, ocean currents, and juvenile natal homing on connectivity, addressed calls for increased genetic sampling in the southwestern Atlantic, and provided data important for conservation of globally endangered green turtles. Expand
Green turtle nesting at Aldabra Atoll ― population estimates and trends
Green turtle (Chelonia mydas) nesting activity was monitored o n the beaches of Aldabra Atoll during the years 1981—1985 to estimate the numbers of egg clutches deposited on the atoll each year. Expand
The Interplay of Homing and Dispersal in Green Turtles : A Focus on the Southwestern Atlantic
Current understanding of spatial ecology is insufficient in many threatened marine species, failing to provide a solid basis for conservation and management. To address this issue for globallyExpand
Current status of the sea turtles nesting on Okinawajima and adjacent islands of the central Ryukyus, Japan
The geographic pattern of the density of body pits calculated on the basis of data from the present and the previous surveys suggests that several beaches in the northern half of Okinawajima are especially important for breeding populations of sea turtles around the central Ryukyus. Expand
Reproductive seasonality and sexual dimorphism in green turtles
Mating was observed to begin before nesting and follow a pattern consistent with a seasonal influx of suitable females into the annual breeding population, and the possible mechanisms behind the evolution of such a pattern are discussed. Expand
The seasonal pattern and distribution of green turtle (Chelonia mydas) nesting activity on Aldabra Atoll, Indian Ocean
The number of beaches being used by the turtles has apparently increased but no clear reason could be provided for the varying levels of use of different beaches. Expand


Demography of the Breeding Population of the Green Turtle, Chelonia mydas, at Tortuguero, Costa Rica
A comparison of niche overlap and species packing and the competition funct on with illustrations from coral reef fish and an introduction to mathematical ecology are shown. Expand
Synopsis of Biological Data on the Green Turtle in the Hawaiian Islands
This report is a synopsis of biological data on the green turtle in the Hawaiian island, including their ecology and life phases, population, exploitation, and the protection and management as ofExpand
Seafloor spreading theory and the odyssey of the green turtle
Seafloor spreading theory seems to explain why the ancestors of a green turtle (Chelonia mydas) subpopulation which now travels 2,000 km from Brazil to breed at Ascension Island, were induced to swimExpand
An Analysis of Sand from Green Turtle Nesting Beaches on Ascension Island
It is concluded that in the absence of disturbance or competition, green turtles have a wide tolerance of physical conditions on their nesting beaches. Expand
Some Aspects of the Nesting Behavior and Reproductive Biology of Sea Turtles
The relatively large number of yolkless eggs laid by many leatherbacks and by some hawksbills invites further study and some aspects of sea turtle nesting behavior and reproduction are compared to those of other chelonians. Expand
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
The problem of open-sea navigation: the migration of the green turtle to ascension island.
The possibility that orientation is based, in part, on the detection of some chemical substance originating at Ascension Island, and the potential advantage of having the hatchlings imprinted by the taste or odor of the waters near their birthplace is considered. Expand
Green Sea Turtles: A Discrete Simulation of Density-Dependent Population Regulation
Field data on the nesting of the green sea turtle were used to construct a stochastic model. This model was simulated by use of a digital computer language simscript (Monte Carlo) to determine theExpand
Swell waves at Saint Helena related to distant storms
This paper discusses the relationship between a frequency-time plot of energy density of swell, from records taken at St Helena in December 1970 and January 1971, and meteorological records ofExpand
