Biological soil crusts greatly contribute to small-scale soil heterogeneity along a grazing gradient

Climatic and soil texture threshold values for cryptogamic cover development: a meta analysis

“…2). BSCs are further known to respond to conditions apart form soil texture and climate, for example to succession after various sources of disturbance (Belnap & Eldridge 2001;Concostrina-Zubiri et al 2013;Spröte et al 2010;Kuske et al 2012;Herrick et al 2010;Muscha & Hild 2006;Dougill & Thomas 2004), to geomorphic characteristics like slope exposition (Kidron et al 2001(Kidron et al , 2010Yair 2001), or to meteorological conditions during sampling.…”

“…Soil texture, in particular, has been found to have significant influence on crust development (Concostrina-Zubiri et al 2013). Different crust types, in particular those dominated by mosses, have been found to be related to total annual rainfall, soil pH, calcium carbonate levels, plant cover, texture, organic carbon, and soil texture, whereas lichen crusts were related to annual rainfall, pH, calcium carbonate levels, plant cover, sheet erosion, organic carbon, and crust cover (Eldridge & Tozer 1997).…”

Development of bacterial communities in biological soil crusts along a revegetation chronosequence in the Tengger Desert, northwest China

“…It would be good to understand more of the factors that together influenced the composition and function of BSC bacteria in long-term revegetation, including BSCs, plants, soil biochemical properties and climate conditions, and the microorganisms that in turn have the positive influence on soil improvement (Li et al, 2007b(Li et al, , 2010. Many reports have interpreted correlations among soil properties and BSCs as an indicator that BSCs are drivers of soil fertility and development (Chamizo et al, 2012;Delgado-Baquerizo, 2013;Yu et al, 2014;Zhang et al, 2010); some have reported the opposite and suggest a direct influence of soil properties on BSC development (Belnap et al, 2014;Bowker et al, 2006a;Bowker and Belnap, 2008;Concostrina-Zubiri et al, 2013;Rivera-Aquilar et al, 2009;Root and McCune, 2012;Weber et al, 2016). These are important questions, and parsing out the interactions of BSCs and soil biogeochemical properties remains an important frontier in BSC research.…”

Biological Soil Crust effects and responses in arid ecosystems: recent advances at the species level

“…y una especie de musgo (Bryum argenteum) sobre las propiedades físico-químicas del suelo en un pastizal semiárido del centro de México (Concostrina-Zubiri et al, 2013). El estudio se llevó a cabo en tres localidades con diferentes regíme-nes de manejo de la tierra: exclusión de ganado y tres niveles de impacto por pastoreo.…”
