LC-MSMS analysis of green sea turtles in Reunion Island

Human activities and climate change have negatively affected the world's oceans, leading to a 30-60% decline in biodiversity and habitats in coastal ecosystems. Marine turtles, as bioindicator species, accumulate contaminants, including trace elements, due to their extensive migration and long life span. However, there is a lack of data on the abundance of these contaminants and their effects on marine turtles' health. This study focuses on analyzing the muscle proteome of juvenile green sea turtles (Chelonia mydas) from Reunion Island. The ultimate goal was to evaluate whether muscle proteome responds to in-situ mixtures of inorganic contaminants to decipher the possible impacts on individual health, thereby identifying potential new biomarkers for long-term monitoring and conservation efforts.
