The role of benthic amphipods in Antarctic trophodynamics: a multidisciplinary study
Long-term controlled feeding experiments have been performed with four Antarctic amphipod species. For several weeks three scavenger and one herbivore species (Abyssorchomene plebs, Pseudorchomene coatsi, Waldeckia obesa and Djerboa furcipes, respectively) have been fed ad libitum with an isotopical...
