Microorganisms of the Phyllosphere: Origin, Transport, and Ecological Functions Open
Microbes are ubiquitous residents of the atmosphere, including the air that we breathe. They are also widely present in terrestrial, marine, and aquatic environments. Typical microbes include viruses, fungi, archaea, bacteria, algae, and b…

Validation of the USPED Erosion and Deposition Model at Schofield Barracks, O‘ahu, Hawai‘i Open
Soil erosion has been recognized as a significant environmental issue in the United States for over 200 years. Numerous attempts have been made to predict and quantify the phenomenon, yet significant issues remain that hinder the accuracy …

Atmospheric transport and mixing of biological soil crust microorganisms Open
Biological soil crusts (BSCs) are created where a diverse array of microorganisms colonize the surface and upper few millimeters of the soil and create a consolidated crust. They were originally described from arid ecosystems where vascul…

Invasive Species Response to Natural and Anthropogenic Disturbance Open
Much of the literature dealing with the biology and management of invasive species has focused on the damaging ecological and economic consequences of invasions (see Chaps. 2 , 3 , and 14 of this volume for review). In this chapter, we shi…

Biological Soil Crusts of the Great Plains: A Review Open
Biological soil crusts (BSCs), or biocrusts, are composed of fungi, bacteria, algae, and bryophytes (mosses, etc.) that occupy bare soil, entwining soil particles with filaments or rootlike structures and/or gluing them together with polys…

Riparian and groundwater-dependent ecosystems of the Bridger-Teton National Forest: An assessment of resources and current conditions Open
This assessment was conducted to provide information on the current conditions of riparian and groundwater-dependent ecosystems in relation to their natural range of variation on the Bridger-Teton National Forest.We summarized dominant rip…

Forest and Rangeland Soil Biodiversity Open
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 for all or part of their lives (Decaëns et al. 2006). A single gram of soil is estimated to …

Reproduction and Dispersal of Biological Soil Crust Organisms Open
Biological soil crusts (BSCs) consist of a diverse and highly integrated community of organisms that effectively colonize and collectively stabilize soil surfaces. BSCs vary in terms of soil chemistry and texture as well as the environment…

Aerobiology and passive restoration of biological soil crusts Open
Biological soil crusts (BSCs) commonly occupy the surface of many arid and semiarid soils, and disturbed soils in more mesic environments. BSCs perform many essential ecological services. Substantial resources have been invested trying to …

Floral orientation in <i>Eulychnia acida</i>, an arborescent cactus of the Atacama Desert, and implications for cacti globally Open
The hyperarid Atacama Desert of northern Chile may be the driest place on Earth. Plants surviving there have adapted a number of unique strategies to cope with the harsh conditions. Many cacti in arid areas tend to produce reproductive org…

Directional orientation of reproductive tissue of Eulychnia breviflora (Cactaceae) in the hyperarid Atacama Desert Open
Many barrel or columnar cacti, including some in the Atacama Desert, produce their reproductive tissue at or near the terminal apices of solitary or minimally branched stems that lean toward the equator, reportedly to maximize exposure to …
