Abstract:

This study aims to determine the Hawksbill Turtle nesting area (Eretmochelys imbricata) Faong Beach, Manusela National Park. The method used in this research is the survey method, namely the direct field data collection and the 2x2 meter square plot method to see the understorey vegetation. The results showed that the characteristics of the hawksbill nesting area (Eretmochelys imbricata) at Faong beach were chosen as one of the most suitable places for turtle nesting.

Abstract:

Tag recoveries from four adult female hawksbill turtles, Eretmochelys imbricata, tagged on the Great Barrier Reef, Australia, are reported. Hawksbill turtles on breeding migrations move between Australia and neighbouring countries including Vanuatu, Solomon Islands, Papua New Guinea and Indonesia. Migratory distances between foraging areas and nesting beaches ranged from 368 to 2425 km. A review of data from tag recoveries, genetic analysis and satellite telemetry indicates that adult female hawksbill turtles often exhibit migratory behaviour parallelling that of other marine turtle species.

Anecdotal evidence of fishermen and dealers in turtle products, measurement of captured animals and personal observations of the authors all point to declines in numbers and average size

The illegal trade of hawksbill turtles is an act prohibited by the CITES Convention of 1973. This Convention aims to protect threatened wildlife and biodiversity. The illicit trade of hawksbill turtles in East Kalimantan warrants serious attention due to the declining population of hawksbill turtles, which is deemed a violation of regulations. The issue revolves around the effectiveness of law enforcement against the illegal trade of hawksbill turtles in East Kalimantan based on the CITES Convention of 1973 and Indonesia’s responsibility in the case of unlawful hawksbill turtle trade in East K

Here we estimate the overall seasonal sex ratios of hatchling hawksbill turtles produced in Bahia, Brazil, during 6 nesting seasons, based on incubation durations, pivotal temperature, and pivotal incubation duration.

Abstract:

Eggs of hawksbill turtles, Eretmochelys imbricata, from Antigua were incubated at constant tempe ratures. The pivotal temperature (the temperature at which 50% of each sex is produced) for the sample was estimated to be 29.2 °C. Sand temperatures at the depth of turtle nests were recorded over two nesting seasons at Pasture Bay, Antigua. Although sand temperatures were sometimes higher than the pivotal temperature, more often they were lower. On this basis, it is unlikely that hatchling hawksbill turtles in this area have the highly female-biased sex ratios reported for some other reptiles.

Abstract:

Of the six species of marine turtle in Papua New Guinea, the green turtle Chelonia mydas and the hawksbill turtle Eretmochelys imbricata are the most common and the most utilized in the Port Moresby region. This paper describes a study carried out in 1989, which monitored the trade in green turtles in the country's main market and the sale of tortoiseshell in a major shopping centre. The price of turtle meat was higher than that of some common reef fish, but cost less when fish was abundant. The commercial trade in tortoiseshell appeared to be negligible. As the urban population increases it i

Abstract:

The hawksbill turtle, Eretmochelys imbricata, has been at risk of extinction for more than 40 years and remains critically endangered. While nesting beach protection is important for hatchling production, identifying inter-nesting, migratory, and foraging habitats is crucial for mitigating threats to population recovery. We report the use of satellite telemetry to monitor movements of 15 hawksbill turtles in the Western Caribbean. Transmitters were deployed on nesting turtles in Honduras (2012 n = 2; 2017 n = 3), Costa Rica (2000 n = 2; 2014 n = 1; 2015 n = 1; 2018 n = 4; 2021 n = 1), and Pana

Abstract:

Sea turtles face a great danger of extinction because of human impacts, and the number of turtle occurrence is decreasing. By interviewing fishermen, coastal residents and authorities combined with field surveys in some places where turtles regularly lay eggs, such as Con Dao and Ninh Thuan, the results show that 05 species of sea turtles were found in Vietnam: The Green (Chelonia mydas), Hawksbill (Eretmochelys imbricata), Olive Ridley (Lepidochelys olivacea), Loggerhead (Caretta caretta) and Leatherback (Dermochelys coriacea). Among them, Green turtles are the most abundant and distributed i

The islands are insignificant nesting sites for the green turtle, Chelonia mydas, and the hawksbill turtle, Eretmochelys imbricata. The N. depressa turtles that nest in western Torres Strait-north-eastern Gulf of Carpentaria are smaller and lay smaller eggs on average than the N. depressa turtles that breed in the southern Great

The complex processes involved with animal migration have long been a subject of biological interest, and broad-scale movement patterns of many marine turtle populations still remain unresolved.

The present-day status of this nesting population provides insight into the conservation of marine turtles, a long-lived species. In 1998 and 1999, the first systematic survey of marine turtle nesting in the Cayman Islands found 38 nests on 22 beaches scattered through the three islands. Three species were found: the green Chelonia mydas, hawksbill Eretmochelys imbricata and loggerhead Caretta caretta turtles. Compar
