Translocation of nitrogen and carbon integrates biotic crust and grass production in desert grassland (2008, background): “The contribution of crusts to soil fertility has been demonstrated in disturbed areas where loss of crusts was found to decrease soil N content by 25–75% (Evans & Belnap 1999) and decrease the N and micronutrient content of nearby plants (Harper & Belnap 2001).”
Biological crusts as a model system for examining the biodiversity–ecosystem function relationship in soils (2010, background): “In addition, numerous BSC activities involving alterations of chemistry or water status in the soil can alter nutrient availability and cycling rates (Harper and Belnap, 2001).”
The role of microorganisms at different stages of ecosystem development for soil formation (2013, background): “Regarding the soil fertility, data from different BSCs indicate that crusts have 200 % higher N content than uncrusted soils from the same site (Harper and Belnap, 2001; Rogers and Burns, 1994; Pointing and Belnap, 2012).”
Recovery of biological soil crusts following wildfire in Idaho (2004, background): “Many cyanobacteria and all cyanolichens associated with crusts also fix atmospheric nitrogen, and may enhance the establishment and survival of vascular plant seedlings by increasing the availability of essential mineral nutrients (Harper and Belnap 2001).”
Correlates of biological soil crust abundance across a continuum of spatial scales: support for a hierarchical conceptual model (2006, background): “Collectively, these organisms are major contributors to whole-system nitrogen (N) fixation (Belnap 2002) and carbon (C) fixation (Beymer & Klopatek 1991) and they enhance mineral nutrient content of soils and associated vascular plants ( Harper & Belnap 2001 ).”
Influence of Biological Soil Crusts on Soil Environments and Vascular Plants (2001, background): “This competitive effect is expected to be most severe for small, short-lived (especially annual) plants that root heavily at the soil surface, which is the area most influenced by the biological soil-crust organisms.We have observed that many plants, including shrubs, produce hair-like feeder roots ”
Biological soil crust development affects physicochemical characteristics of soil surface in semiarid ecosystems (2012, background): “Several publications have reported up to a 300% increase in soil C content (Rao and Burns, 1990; Rogers and Burns, 1994) and an increase in soil N of up to 200% (Rogers and Burns,1994; Harper and Belnap, 2001) due to the presence of BSCs. Malam Issa et al. (1999) found that the presence of BSCs impr”
Soil nematode communities are ecologically more mature beneath late- than early-successional stage biological soil crusts (2007, background): “, 1992) and mineral chelation and retention (Belnap and Harper, 1995; Harper and Belnap, 2001).”
Biological soil crusts and their microenvironment: Impact on emergence, survival and establishment of seedlings (2009, background): “Alteration of soil by BSCs is correlated with an increase of some elements in phytomass (Harper and Belnap, 2001; Harper and Pendleton, 1993).”
Soil lichen and moss cover and species richness can be highly dynamic: The effects of invasion by the annual exotic grass Bromus tectorum, precipitation, and temperature on biological soil crusts in SE Utah (2006, background): “Plant productivity and concentrations of most plant-essential nutrients are higher in plants growing in crusted soils compared to adjacent uncrusted soils and plants often have increased survivorship (Harper and Belnap, 2001; for more references, see Belnap et al., 2003).”
Biological soil crusts greatly contribute to small-scale soil heterogeneity along a grazing gradient (2013, background): “The retention of fine , nutrient rich particles and the secretion of organic acids by D . diacapsis may explain the lower pH values and an overall higher nutrient avail - ability ( Harper and Belnap , 2001 ; Beraldi - Campesi et al .”
