Short summary
The Weddell Sea is one of the most studied marine ecosystems outside the Antarctic Peninsula in the Southern Ocean. Yet, few studies consider the complexity of the Weddell Sea food web, which comprises 490 species and 16041 predator–prey interactions. Here we analysed a quantitative version of the Weddell Sea food web, where the interactions’ intensity is explicitly considered. We found that only a few species of marine mammals, sea birds, and fishes are important for the food web stability.
