Накратко на български

Генетичният състав на зелените костенурки в Югозападния индийски океан се анализира чрез ДНК, за да се установи връзката между популациите и местата им на гнездене. Това помага за създаването на по-точни мерки за опазване, съобразени с нуждите на всяка група.

Conservation genomics of endangered green sea turtles

The Southwest Indian Ocean (SWIO) is known as a biodiversity hotspot. It has diverse marine ecosystems, including coral reefs, rocky shores, and mangroves. These habitats are home to diverse marine life, including five species of marine turtles. The green turtle (Chelonia mydas) plays a vital role in these habitats by maintaining the ecological balance in these environments. However, conservation and management of marine turtle populations is challenging because they face many threats, including direct harvesting and bycatch in fisheries, habitat degradation, pollution, and the effects of climate change. In addition, their mainly aquatic life history and the large distances they travel make them difficult to study. The SeaTGen project aims to improve our understanding of the spatial structure and genetic makeup of green turtles in the SWIO. We do this using the turtles' DNA to 1) understand how turtle populations are related and 2) to trace marine turtles in the ocean back to their nesting origins. The information gathered through this project can help us to link turtles to their population origins more accurately, which is crucial for developing conservation efforts that target the specific needs of each turtle population. Furthermore, this data can be used to identify and establish efficient conservation units, such as Regional Management Units.

Цел на проекта

Conservation and management of marine turtle populations are challenging because of their complex life history involving long-distance migrations. Consequently, marine turtles are affected by a wide range of anthropogenic threats across temporal and spatial scales, including climate change. The cumulative effect of these impacts is likely to have direct and indirect implications on these endangered species in the near future. This project aims to refine our understanding of the spatial structure of green turtles (Chelonia mydas) in the South-West Indian Ocean to understand better how populations interact and how they may be impacted by threats both at the nesting ground, at distant foraging areas, and along migratory corridors. To do so we aim to apply the power of genome-wide Single Nucleotide Polymorphisms (SNPs) combined with traditional mtDNA markers to assess fine-scale population structure and recent demographic history. In addition, the research will take a multidisciplinary approach, combining novel genetic methods with data from movement ecology (satellite telemetry) and oceanography (ocean current modelling) to provide a comprehensive analysis of connectivity between breeding and foraging areas. The results will allow conservation managers and policymakers to identify areas in need of protection and to assess the potential impacts of anthropogenic activities such as marine turtle interaction with fisheries. As such, our results will provide the scientific basis for future conservation actions within the framework of Integrated Maritime Policy. This project will allow me to gain critical new skills in conservation genomics. This will broaden my research horizon, strengthen my research profile and place me in a strong position for furthering my research career within the European Community.
