Microbial symbionts of marine sponges play important roles for the hosts and also for their ecosystems. The unique tolerance of marine sponges to a wide diversity of microbial symbionts allows them to acquire a wide variety of “evolutionary solutions” to environmental challenges. Ice scour is one of the main forces structuring Antarctic benthic communities, and its effect is expected to increase as further warming is projected for the Western Antarctic Peninsula (WAP). The interaction of these physical drivers may have a significant impact, shaping the microbiome of Antarctic sponges under current and future scenarios of climate change. The aim of this research was to assess how stressors, such as warming and injuries produced by ice scour, affect the microbiome of the marine Antarctic sponge Isodictya kerguelenensis under current and predicted scenarios. Individuals of I. kerguelenensis were sampled in shallow waters (10 m) off the coast of Doumer Island, Palmer Archipelago, WAP. In order to mimic the effect of tissue damage produced by ice scour, tissue samples were taken at days 0 (T0d) and 15 (T15d) from individuals placed in a control (0.5°C) and two temperature treatments (3 and 6°C).
