Succession of a Glacial Moraine in Alaska

Abstract: A 4 page overview of ecological succession as it occurs on glacial moraines. The author emphasizes the importance of lower species such as lichens, mosses, and bacteria. The crushed rock composing the moraines offers little in terms of nutrients to support more complex species. The job of the initial colonizers thus becomes one not only of gaining a toehold to support their own propagation but also of creating biomass to ultimately allow the establishment of more demanding species. Bibliography lists 5 species.
