How does the decline of sea turtle populations influence marine biodiversity?

The decline of sea turtle populations in Mallorca, as in other regions, significantly impacts marine biodiversity. Sea turtles, particularly the loggerhead turtle, play a crucial role in marine ecosystems. By grazing on seagrass beds, they help maintain the health and productivity of these vital habitats, which serve as homes for numerous marine species. Healthy seagrass ecosystems also contribute to carbon sequestration, helping mitigate climate change.

Furthermore, sea turtles are integral to the food web; their decline can lead to overgrowth of seagrass and changes in species composition, disrupting the balance of marine life. For instance, an increase in jellyfish populations, often associated with the decline of sea turtles that feed on them, can result in negative consequences for fisheries and other marine organisms. Additionally, the decline of such keystone species can indicate broader environmental issues, including habitat degradation and pollution, which also threaten the overall health of marine ecosystems. Thus, protecting sea turtle populations is vital for maintaining marine biodiversity and ecosystem function in the waters surrounding Mallorca.
