The influence of penguin activity on soil diatom assemblages on King George Island, Antarctica with the description of a new Luticola species
Background Ice-free areas in the Antarctic region are strongly limited. The presence of marine mammals and birds in those areas influence soil properties and vegetation composition. Studies on the terrestrial diatom flora in soils influenced by sea birds in the Maritime Antarctic region are scarce....
