Bromus tectorum Litter Alters Photosynthetic Characteristics of Biological Soil Crusts from a Semiarid Shrubland
Invasion by the exotic annual grass Bromus tectorum has increased the cover and connectivity of fine litter in the sagebrush steppes of western North America. This litter tends to cover biological soil crusts, which could affect their metabolism and growth. To investigate this possible phenomenon, biological soil crusts dominated by either the moss Bryum argenteum or the lichen Diploschistes mu...
متن کاملSuppression of annual Bromus tectorum by perennial Agropyron cristatum: roles of soil nitrogen availability and biological soil space
Worldwide, exotic invasive grasses have caused numerous ecosystem perturbations. Rangelands of the western USA have experienced increases in the size and frequency of wildfires largely due to invasion by the annual grass Bromus tectorum. Rehabilitation of invaded rangelands is difficult; but long-term success is predicated on establishing healthy and dense perennial grass communities, which sup...
متن کاملBiological soil crusts affect small-scale spatial patterns of inorganic N in a semiarid Mediterranean grassland
The influence of biological soil crusts (BSCs) on the small-scale spatial distribution of inorganic nitrogen (N) in drylands is largely unknown, despite their known impact and importance on the N cycle in these environments. We evaluated how perennial plants and BSCs affected small-scale spatial patterns of soil inorganic N (ammonium and nitrate) availability in a semiarid grassland from Spain....
متن کاملEffect of lichen biological soil crusts on soil properties derived from early Holocene sandy sediments
Introduction: Biological soil crusts are a community of cyanobacteria, fungi, lichens, and mosses and play key roles in arid and semi-arid regions including carbon and nitrogen accumulation, soil fertility, dust capture, soil conservation and stability. Recent studies show that the formation of biological soil crusts on mobile dunes areas is extremely difficult due to low vegetation cover, st...
متن کاملMicrofauna Within Biological Soil Crusts
A variety of microfauna inhabit the biological soil crusts (biocrusts) of arid soils from all parts of the globe, including the southwestern USA (Bamforth 2004, 2008; Darby et al. 2006, 2007a, b; Neher et al. 2009), the Negev Desert of Israel (Jones and Shachak 1990; Pen-Mouratov et al. 2011), the Tengger Desert of northern China (Liu et al. 2011; Li et al. 2011), Australia (Robinson et al. 200...
