Hawksbill sea turtles (Eretmochelys imbricata) from the Hawaiian archipelago form a small and genetically isolated population, consisting of only a few tens of individuals breeding annually. Most females nest on the island of Hawai’i, but little is known about the demographics of this rookery. This study used genetic relatedness, inferred from 135 microhaplotype markers, to determine breeding sex-ratios, estimate female nesting frequency and assess relationships between individuals nesting on different beaches.

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.

A BIORAP is a biological inventory programme undertaken in marine and terrestrial environments, and is designed to rapidly assess the biodiversity of highly diverse areas. Options to manage threats and protect biodiversity of national or international significance are recommended to governing communities.

This report is targeted at policy-makers, particularly those responsible for developing climate mitigation and adaption strategies that address issues like conservation, ecosystem services, agriculture and sustainable livelihoods. It focuses on the primary linkages between invasive species and climate change, as well as the secondary and tertiary interactions of their corresponding impacts. Finally, the enclosed recommendations are intended to provide guidance on the best ways to integrate invasive species prevention and management into the consideration of climate change responses across a range of sectors. Building on a review of existing scientific and conservation literature (which is frequently centered on well-studied invasive species in developed countries), our research has reaffirmed that there are significant gaps and questions about the intersection of these two major drivers of change. The case studies included below highlight key relationships and questions related to invasive species, climate change and the role of ecosystem-based adaptation. The three key messages that can be distilled from this report are: 1. Climate change will have direct and second order impacts that facilitate the introduction, establishment and/or spread of invasive species. 2.Invasive species can increase the vulnerability of ecosystems to other climate-related stressors and also reduce their potential to sequester greenhouse gasses. 3.Using an ecosystem-based adaptation approach, these pressures on ecosystems and their ability to provide important services can be offset by preventing the introduction of new invasive species and by eradicating or controlling those damaging species already present.

Cheloniid turtles are characterised by a complicated life history: their eggs are laid on warm beaches; hatchling sex is determined temperature dependent sex determination during embryonic development; lack of parental care; hatchlings are imprinted to the natal area; hatchlings disperse to feed on plankton in the pelagic environments followed by inshore recruitment to feed on benthic organisms; immature turtles have slow growth and delayed maturation; adults migrate to breed in their respective natal area; they lay multiple clutches in a breeding season but dot normally breed annually; adults display high fidelity to both their respective breeding and the feeding areas and have an extended adult life (Hirth. 1997).
What can be done to restore Pacific turtle populations? The Bellagio blueprint for Action on Pacific Sea turtles
Island and Ocean Ecosystems

2004
The Pacific Ocean is the habitat of 5 species of widely distributed sea turtles and one restricted to Australian waters that evolved nearly 30 millions of years ago. All species are long-lived and clow growing, they take form 10 to 30 years to reach maturity and exhibit complex life cycles involving eggs laid in nests on tropical beaches natal homing and extraordinary feeding and breeding migrations that can span the entire Pacific Ocean. Sea turtle populations are slow to increase and replace themselves.
