Fire disturbance belowground: untangling consequences for soil food webs and organic matter
Soils and the ecological communities they house provide a diverse array of ecosystem services including the provisioning of food and fiber, decomposition and nutrient cycling, water filtration, and the maintenance of terrestrial biodiversity. These complex belowground communities, and therefore the …

Monitoring the influx of marine derived Nitrogen and characterizing soil food webs of riparian zones of the Elwha River Watershed, WA, USA.
… post dam removal. I sampled riparian soil and vegetation along three tributaries, representing either the lower (undammed reference), middle (accessible since 2012), or upper Elwha (no anadromous salmon control). I was not able to detect MDN in soil or vegetation at any of the …

Bottom-up effects of aboveground biota, invasive species and drought on soil animal communities
Soil ecosystems are facing the threat of a growing human population and the consequent global changes. Soil food webs are being exposed to unprecedented levels of disturbance, with the potential to disrupt the regulating interactions between soil biota components, and the role these components play …

Multi-scale Studies of Microbial Mats and Biocrusts: Integrating Remote Sensing with Field Investigations in Antarctica's McMurdo Dry Valleys
… form visually conspicuous layers on sediment, soil, and rock surfaces, called microbial mats and biological soil crusts (i.e., biocrusts). Both microbial mats and biocrusts consist of cyanobacteria, moss, diatoms, and green algae, and also support diverse heterotrophic taxa. These communities …

Invertebrate mediated biodiversity-ecosystem functioning relationships : lessons from tropical forest dung beetles
… and trophic complexity in grasslands and soil food webs are positively associated with the cycling of nutrients in soil and water, primary productivity and decomposition. Since these ecosystem processes underpin a number of goods and services to society, human-driven changes in the …
