Climate change effects on organic matter decomposition rates in ecosystems from the Maritime Antarctic and Falkland Islands
Antarctic terrestrial ecosystems have poorly developed soils and currently experience one of the greatest rates of climate warming on the globe. We investigated the responsiveness of organic matter decomposition in Maritime Antarctic terrestrial ecosystems to climate change, using two study sites in...
