Other G-proteins, in more usual cellular environments, would dilute in the cytoplasm if they were released fro

ing of the individual components involved during the fibrillation, notably without physical separation of the species. In this chapter we explain how to optimize a small angle scattering analysis of the fibrillation process and the basic principles behind analysis of the data. We include several pra

nd hybrid modelling approaches, solution scattering is synergistically used with other structural techniques utilizing the complementary information such as atomic models of the components, intramolecular contacts, subunits orientations etc. for the reconstruction of complex systems. The usual requi

uch as propagule banks and the presence of other biocrust organisms. Primary colonists such as cyanobacteria and fungi typically facilitate establishment, and bryophytes often occur in the later stages of crust development. Ecologically, biocrust bryophytes provide habitats for other crust community

significant soil properties influencing the cover, richness, and composition of biocrusts in dryland environments are soil texture, pH, and calcareousness. Additionally, gypsiferous soils are often associated with distinct floras and high abundance and diversity of biocrusts, especially lichens. At
