Phototrophic Mats of the Desert: The Bacteria of the Biological Soil Crust Community
Biological soil crusts (biocrusts) are surface soil communities that can be made up of cyanobacteria, lichens, heterotrophic bacteria, archaea,...

Diversity of Viridiplantae DNA present on rock surfaces in the Ellsworth Mountains, continental Antarctica
The Ellsworth Mountains experience frigid desert conditions. No macroscopic vegetation is present, with only very few published records of...

Desert Dust as a Vector for Cyanobacterial Toxins
Drylands, which make up 41–45% of the Earth’s land area, are inhabited by 31% of the world’s human population and are characterized by climatic...
-
Forest and Rangeland Soil Biodiversity
Regardless of how soil is defined, soils are the most diverse of all ecosystems. It is estimated that 25–30% of all species on Earth live in soils...
-
Hydrology and Erosion Processes
A common theme throughout this book are the environmental and biological components commonly associated with soil health. The soil environment is not...
-
Cyanobacteria and loess—an underestimated interaction
BackgroundBiocrusts are important functional units in dryland ecosystems. Regarded as ecosystem engineers, cyanobacteria in biocrusts contribute...

How Biological Soil Crusts Became Recognized as a Functional Unit: A Selective History
It is surprising that despite the worldwide distribution and general importance of biological soil crusts (hereafter referred to as biocrusts),...
-
Microfauna Within Biological Soil Crusts
Biocrusts serve as unique habitat for a broad range of microfauna, including protozoa, nematodes, tardigrades, rotifers, mites, collembolans, and...

Easy-to-make portable chamber for in situ CO2 exchange measurements on biological soil crusts
Commercial chambers for in vivo gas exchange are usually designed to measure on vascular plants, but not on cryptogams and other organisms forming...

Structure, Composition, and Function of Biocrust Lichen Communities
In this chapter we examine the structure, composition, and function of soil biocrust (i.e., biological soil crust) communities dominated by lichens....

Description of Pseudomonas asuensis sp. nov. from biological soil crusts in the Colorado plateau, United States of America
A Gram-negative, aerobic, non spore-forming, non-motile, rod-shaped, yellow pigmented bacterium CP155-2 T was isolated from a biological soil crusts...

The nutrient plasticity of moss-dominated crust in the urbanized Sonoran Desert
AimsIn deserts, moss-dominated crusts may play an important role in terrestrial-aquatic and aboveground-belowground connections. Despite its...

Spatial distribution of microbial communities associated with dune landform in the Gurbantunggut Desert, China
The microbial community compositions and potential ammonia oxidation in the topsoil at different positions of sand dune (stoss slope, crest, lee...

Physiological Ecology of Dryland Biocrust Mosses
Soil biocrusts are assemblages of cyanobacteria, lichens, and mosses ubiquitous to arid and semi-arid (dryland) systems that offer an array of...

Dynamics of periphyton nitrogen fixation in short-hydroperiod wetlands revealed by high-resolution seasonal sampling
Periphyton N 2 fixation plays a key role in N cycling of aquatic systems, but temporal studies of this process are often lacking, especially in...
-
Ecophysiological responses of desiccation-tolerant cryptobiotic crusts
In our present studies, the recovery of photosynthetic activity after rehydration was demonstrated. We measured chlorophyll fluorescence, CO 2 gas...
-
Shifting Species Interaction in Soil Microbial Community and Its Influence on Ecosystem Functions Modulating
The supportive and negative evidence for the stress gradient hypothesis (SGH) led to an ongoing debate among ecologists and called for new empirical...

Spatial variation of arbuscular mycorrhizal fungi in two vegetation types in Gurbantonggut Desert
Geostatistical techniques were used to assess the spatial patterns of spores densities and biovolume of arbuscular mycorrhizal fungi (AMF) in soils...

Life at the hyperarid margin: novel bacterial diversity in arid soils of the Atacama Desert, Chile
Nearly half the earth’s surface is occupied by dryland ecosystems, regions susceptible to reduced states of biological productivity caused by climate...
