Vulnerability of Marine Turtles to Climate Change

Marine turtles are generally viewed as vulnerable to climate change because of the role that temperature plays in the sex determination of embryos, their long
life history, long age-to-maturity and their highly migratory nature. Impacts of different consequences of climate change, such as temperature and sea level rise, extreme weather events etc. in combination with anthropogenic pressures are discussed in this book chapter.

Global Dugong Genetics Project

The Global Dugong Genetics Project aims to examine the phylogeography of the dugong based on historical samples from throughout the dugong’s range. It will update conservation and management actions through mapping the distribution of discrete dugong populations; identifying historical and potential migratory routes; and highlighting small populations as a priority for conservation. The Project was a collaboration between James Cook University and Nelson Mandela Metropolitan University.

GEF Dugong and Seagrass Conservation Project

The GEF-5 Project represents a major international collaboration. It is unique in being the first coordinated approach to enhance the effectiveness of conservation of dugongs and their seagrass ecosystems through community-based stewardship, incentive-based conservation, removal of knowledge barriers and national and regional mainstreaming activities. The project covers 38 national projects, managed in collaboration with 26 local partners in Indonesia, Madagascar, Malaysia, Mozambique, Sri Lanka, Solomon Islands, Timor-Leste and Vanuatu.

First Report of Metallic Elements in Loggerhead and Leatherback Turtle Eggs from the Indian Ocean

Bio-monitoring of pollutants in long-lived animals such as sea turtles is an important tool in ecotoxicology. We present the first report on metallic elements in sea turtle eggs from the Indian Ocean. Eggs of the leatherback and loggerhead turtle that breed on the Indian Ocean coast of South Africa were analysed for 30 elements. The eggshells and egg contents of the loggerhead turtle, the smaller of the two species, had higher or significantly higher concentrations than leatherbacks, except for strontium - the reason is unknown.

Metals in Blood and Eggs of Green Sea Turtles (Chelonia mydas) from Nesting Colonies of the Northern Coast of the Sea of Oman

The green sea turtle (Chelonia mydas) has been a species of global concern for decades. In this study, heavy metals (mercury: Hg; Cadmium: Cd; Lead: Pb; Copper: Cu; and Zinc: Zn) were measured in blood and three egg fraction of green sea turtles nesting on the northern coast of Sea of Oman. Heavy metals concentrations in blood, yolk, albumen, and egg shell ranged between 0.16–36.78, 0.006–33.88, 0.003–4.02, and 0.002–6.85 μg/g (ww), respectively.

Genetic Diversity of the Green Turtle (Testudines: Cheloniidae: Chelonia mydas (Linnaeus, 1758)) Population Nesting at Kosgoda Rookery, Sri Lanka

We determined the genetic diversity of the Green Turtle Chelonia mydas (Linneaus, 1758) nesting at Kosgoda rookery, the second largest sea turtle aggregation on the southwestern coast of Sri Lanka. Skin tissue samples were collected from 68 nesting females and genetic diversity was estimated using six microsatellite loci. High genetic diversity was observed within the population as all loci analyzed were highly polymorphic with a total of 149 alleles observed.

Eretmochelys imbricata: Lessons to Learn from a Monitoring Program in the North of Mozambique

Monitoring programs for nesting turtles around the world have been important to build up a matrix of information for better comprehension of their behaviour and dispersion. The Western Indian Ocean has several monitoring programs that are being used to reveal migration routes, phylogenetic interconnections and nesting behaviour patterns. We determined the nesting parameters for 69 records of hawksbill turtles collected during the Vamizi Island monitoring program.
