Identification of groups of metabolically-active rhizosphere microorganisms by stable isotope probing of PLFAs
Abstract We combined microbial community phospholipid fatty acid (PLFA) analyses with an in situ stable isotope 13 CO 2 labelling approach to identify microbial groups actively involved inExpand

How does the Fungal Endophyte Neotyphodium coenophialum Affect Tall Fescue (Festuca arundinacea) Rhizodeposition and Soil Microorganisms?
The goal of our study was to investigate the impact of fungal endophytes in tall fescue (Festuca arundinacea) on rhizodeposition and in turn, the soil microbial community. Sand-based, asepticExpand

Effects of a one-year rainfall manipulation on soil nematode abundances and community composition
Abstract Soil nematodes play a crucial role in the terrestrial nitrogen cycle by accelerating the release of ammonium from microorganisms (bacteria and fungi). As aquatic organisms, nematodes areExpand

Characterization of soil nematode communities in three cropping systems through morphological and DNA metabarcoding approaches
We used complementary morphological and DNA metabarcoding approaches to characterize soil nematode communities in three cropping systems, conventional till (CT), no-till (NT) and organic (ORG), fromExpand

Invertebrate Biodiversity in Antarctic Dry Valley Soils and Sediments
ABSTRACT We studied invertebrate communities across a transition zone between soils and stream sediments in the cold desert landscape of Taylor Valley, Antarctica. We hypothesized that hydrologicalExpand

The use of anhydrobiosis by soil nematodes in the Antarctic Dry Valleys
1. Anhydrobiosis is a survival strategy used by soil nematodes that confers protection from environmental stress and is induced by desiccation. 2. To study the use of anhydrobiosis by soilExpand

Effects of organic amendment and tillage on soil microorganisms and microfauna
Abstract Soil microorganisms (bacteria, fungi) and microfauna (nematodes, protozoa) have been shown to be sensitive to organic amendments, but few experiments have investigated the responses of allExpand

Field and Microcosm Studies of Decomposition and Soil Biota in a Cold Desert Soil
In the extreme cold desert soil of the McMurdo Dry Valleys of Antarctica, we studied the effects of changing moisture and temperature on rates of decomposition and the activity and abundance of soilExpand

Interactions between fertilizer addition, plants and the soil environment: implications for soil faunal structure and diversity
The linkages between plants and soil biota are both important and complex, involving both positive and negative feedbacks between soil organisms and their physical environment. An experiment wasExpand
