Alarm at the Blue: Why Large Predators in the Balearic Sea Leave Almost No Traces

Answer

What does the decline of large predatory sharks mean for Mallorca's marine life?

Large predators regulate stocks, migrations, and food webs, so their decline can shift coastal ecosystems and fish communities. A study around Cabrera using environmental DNA found virtually no traces of big species in roughly 80 samples across twelve sites, though the method has limits. This absence signals potential ecosystem changes that deserve careful monitoring.
