Hawksbill turtle (Eretmochelys imbricata) nesting populations and behaviors in the Republic of Vanuatu are poorly understood. In an effort to evaluate their internesting home range, post-nesting migration and foraging habitat home ranges, 7 post-nesting hawksbill turtles were satellite tagged at Moso Island, Republic of Vanuatu between January 2018 and January 2020. The mean internesting home ranges of two turtles was 0.8 km2 proximal to their nesting beach indicating possible value in establishing a marine protected area along the north coast of Moso Island during the nesting season. The Great Barrier Reef, Australia and New Caledonia were the two major post-nesting destinations. Hawksbill turtles are legally protected by law in both countries. Foraging home ranges for 4 hawksbill turtles in New Caledonia and Aneityum Island, Vanuatu ranged from 1.7 to 28.9 km2. It will be important to continue this study to better determine the total area of habitat utilization of the internesting hawksbills at Moso Island in order to facilitate the implementation of community-based conservation measures and to illuminate home range location and size.

Since the 1950's, 19 algal species were intentionally (e.g., aquaculture food) and/or accidentally (e.g., ballast water) introduced into Hawaii (Glenn and Doty 1990).

Technical report

The inextricable links between climate change and sustainable development have been increasingly recognised over the past decade. In 2007, the Intergovernmental Panel on Climate Change (IPCC)1 concluded with very high confidence that climate change would impede the ability of many nations to achieve sustainable development by mid-century and become a security risk that would steadily intensify, particularly under greater warming scenarios. Article 4.8 of the United Nations Framework Convention on Climate Change (UNFCCC) lists several groups of countries that merit particular consideration for assistance to adapt to climate change “especially: (a) small island countries, (b) countries with low-lying coastal areas, c) countries with areas prone to natural disasters.” Small Island Developing States (SIDS) have characteristics which make them particularly vulnerable to the effects of climate change, sea level rise (SLR) and extreme events, including: relative isolation, small land masses, concentrations of population and infrastructure in coastal areas, limited economic base and dependency on natural resources, combined with limited financial, technical and institutional capacity for adaptation.2
