Development of the polysaccharidic matrix in biocrusts induced by a cyanobacterium inoculated in sand microcosms (2017, background): “plained as due to shrinking and swelling of clay minerals (Williams et al. 2012) and to the viscoelastic properties of EPSs (Navarini et al.”
Biological soil crust and disturbance controls on surface hydrology in a semi-arid ecosystem (2017, result): “Their argument that the large pore space found in sandy soils can decrease runoff levels is analogous to that offered by other studies (Warren 2001, Williams et al. 2012, Zaady et al. 2014).”
Complex role of the polymeric matrix in biological soil crusts (2018, background): “In natural dry hot environments the formation of cracks may provide open pathways to increase soil permeability and aeration under crust layers (Williams et al. 2012), leading to new colonizable niches with enhanced moisture regimes (Danin et al.”
Early life on land and the first terrestrial ecosystems (2013, background): “The capacity of microbes to trap and bind particles has been demonstrated for numerous underwater and subaerial environments (Gunatilaka 1975; Zhang 1992; Takeuchi et al. 2001; Altermann 2008; Gradzinski et al. 2010; Williams et al. 2012).”
