The west coast of Galathea Bay, Great Nicobar Island, was previously a significant nesting site for leatherback turtles despite pressure from anthropogenic activities and natural predators. The nesting population has the potential to recover from disturbance resulting from the 2004 Indian Ocean tsunami, as human all settlements have gone and the region is, therefore, free of anthropogenic predation and light pollution which might affect nesting turtles. However, there is still predation of turtle nests by Nicobari pigs.

The ecology and reproductive biology of the hawksbill turtle, Eretmochelys imbricata were studied in Kish Island, Persian Gulf. The studied parameters include: environmental factors such as air temperature and humidity, soil types in different habitats during the breeding season; parameters related to the females' body and hatchlings biometrics i.e. weight, curved carapace length (CCL), straight carapace length (SCL), curved carapace width (CCW) and straight carapace width (SCW); and parameters related to reproductive biology, i.e.

In India, the Gahirmatha coast is among the most important nesting grounds of olive ridley turtles, Lepidochelys olivacea. The coastal waters of Odisha are also subjected to heavy commercial fishing activities, leading to turtle-fisheries conflicts. This study was carried out to quantify the effects of fishing on breeding turtles. Data on stranded, dead turtles were collected during three breeding seasons (2007–08, 2008–09 and 2009–10) between November and April along a 35 km stretch. A total of 13,443 dead olive ridleys were counted (2008–09: n=9502, 2007–08: n=2754, 2009–10: n=1187).

Current study emphasizes on recent very severe cyclonic storm Phailin of category -5 hurricane has caused significant morphologic changes in Olive Ridley sea turtle nesting ground in estuarine region of Rushikulya, east coast of India. In the present study, we have used Remote Sensing and GIS tools for investigating and quantifying the morphologic changes especially the sand spit of the study domain. Sequential satellite data (Geoeye & Landsat-8) pertaining to the period 2003 to 2014 were used in the current study.

In the past two decades, sea turtle mortality has increased due to a variety of anthropogenic activities along the Nagapattinam and Chennai coast region in Tamil Nadu, South India. Weekly field surveys were conducted over an eight-month period from December 2013 to July 2014 to monitor the mortality of turtles in these coastal areas, revealing a notable disruption in the nesting activity of the turtles during January–March; the worst affected were mature individuals.

Stomach contents of olive ridley turtles (Lepidochelys olivacea) occurring along the Gahirmatha coast of Odisha, India have been studied between October 2008 and May 2010. We obtained 76 stomach contents from olive ridley turtles that were stranded freshly, of which 12 were males and 64 were females. Among food items, molluscs dominated with 34.5 % in volume while crustaceans were next in order of volume (27.6 %). Occurrence of fish and other invertebrate and algae fragments though were less in amount have been noted almost in all specimens.

Situated about 500 km off the Malagasy east coast, the island of Tromelin is a key nesting site for the endangered green turtle, Chelonia mydas, in the south Western Indian Ocean. Nesting turtles found in this isolated island have been closely monitored since the 1970s, but the most recent estimates of nesting parameters date from 1986.

The most recent climate change projections show a global increase in temperatures along with precipitation changes throughout the 21st century. However, regional projections do not always match global projections and species with global distributions may exhibit varying regional susceptibility to climate change. Here we show the effect of local climatic conditions on the hatchling output of leatherback turtles (Dermochelys coriacea) at four nesting sites encompassing the Pacific, Atlantic and Indian Oceans. We found a heterogeneous effect of climate.

Threatened species are dependent on conservation, with strategic approaches underpinned by the principle of complementarity to find efficient solutions. But are paper-efficient designs always field-effective? After 51 years of monitoring a 56-km-long overlap of two turtle rookeries, there are contrasting population-recovery trends: Vulnerable loggerhead abundance is increasing; and Critically Endangered leatherback abundance is remaining constant, despite leatherback individuals having a higher reproductive output.

To refine our understanding of the spatial structure of the green turtle (Chelonia mydas) populations in the South West Indian Ocean (SWIO), we analysed patterns of mitochondrial DNA (396 base pairs control region fragment) variation among 171 samples collected at five distinct locations (Kenya, Northern Mozambique, and three locations in the Republic of Seychelles: the Granitic, Amirantes, and Farquhar groups) and compared them to genetic data (n = 288), previously collected from 10 southern locations in the SWIO.
