The Microbial Loop at the Surface of a Peatland:Structure, Function, and Impact of Nutrient Input
TLDR
The structure of the protist community in the subaquatic peatland was completely different from that reported for lakes or marine environments and the relative importance of heterotrophic microorganisms was higher than in marine or lacustrine environments. Expand
Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions.
TLDR
It is suggested that warming will destabilize C and nutrient recycling of peatlands via changes in above- and belowground linkages, and therefore, the microbial food web associated with mosses will feedback positively to global warming by destabilizing the carbon cycle. Expand
Carbon balance of a European mountain bog at contrasting stages of regeneration.
TLDR
The recovery of vegetation in the authors' naturally regenerating bog was beneficial for the carbon sequestration after the relatively short period of 20 yr, and air temperature and vegetation index were the two main determinants of ecosystem respiration and gross photosynthesis at light saturation. Expand
Exploitation of northern peatlands and biodiversity maintenance: a conflict between economy and ecology
Peatlands are ecosystems of exceptional conservation value because of their beauty, biodiversity, importance in global geochemical cycles, and the paleoenvironmental records they preserve. CommercialExpand
Horizontal Distribution Patterns of Testate Amoebae (Protozoa) in a Sphagnum magellanicum Carpet
TLDR
The results confirmed the existence of significant broad- and fine-scale spatial structures within testate amoebae communities that could in part be interpreted as effects of ecological gradients, and showed that, on a surface area of 0.25 m2, ecological conditions which look uniform from a macroscopic point of view are not perceived as such by Sphagnum-inhabiting organisms. Expand
Microbial diversity and ecological networks as indicators of environmental quality
Evaluating the quality of ecosystems in terms of biological patrimony and functioning is of critical importance in the actual context of intensified human activities. Microbial diversity is commonlyExpand
Structure of microbial communities in Sphagnum peatlands and effect of atmospheric carbon dioxide enrichment
TLDR
The increase in bacterial biomass is interpreted as a response to a C02-induced enhancement of Sphagnum exudation, and the causes for the decrease of testate amoebae are unclear but could indicate a top-down rather than a bottom-up control on their density. Expand
An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming
TLDR
It is found that five years of consecutive summer warming with peaks of +2 to +8°C led to a 50% reduction in the biomass of the dominant mixotrophs, the mixotrophic testate amoebae (MTA). Expand
Atmospheric phenanthrene transfer and effects on two grassland species and their root symbionts: A microcosm study
TLDR
Neither biomass accumulation nor symbiotic association was affected in ryegrass, probably due to a lower sensitivity of this species to PHE exposure, and Perspectives of carbon allocation and nitrogen nutrition perturbations are suggested in clovers. Expand
