Spatial distribution of birds and terrestrial plants in Bunger Hills
Abstract In this paper, we synthesize recorded observations of moss, lichen and bird species in Bunger Hills, East Antarctica, and assess the role of environmental controls, including sediment, salinity, moisture and geology, on species' distributions. The distribution of snow petrels ( Pagodro...
