Genesis of Acetate and Methane by Gut Bacteria of Nutritionally Diverse Termites
TLDR
Findings should help refine global estimates of carbon dioxide reduction in anoxic habitats and the contribution of termite emissions to atmospheric methane concentrations.
P for Two, Sharing a Scarce Resource: Soil Phosphorus Acquisition in the Rhizosphere of Intercropped Species1
TLDR
The relevance of a range of root-induced or microbially-mediated rhizosphere processes driving P acquisition are discussed, and how complementarity may operate when cereals are intercropped with legume by addressing cases of complementary use of soil P resources in space and time.
Global decomposition experiment shows soil animal impacts on decomposition are climate-dependent
TLDR
Inclusion of soil animals will improve the predictive capabilities of region- or biome-scale decomposition models, soil animal influences on decomposition are important at the regional scale when attempting to predict global change scenarios, and the statistical relationship between decomposition rates and climate, at the global scale, is robust against changes in soil faunal abundance and diversity.
Molecular phylogenetic profiling of prokaryotic communities in guts of termites with different feeding habits.
TLDR
The relative abundances of 16S-like archaeal rRNA in guts were positively correlated with rates of methane emission by live termites, and were consistent with previous work linking high relative rates of methanogenesis with the soil (humus)-feeding habit.
Isolation and physiological study of an amylolytic strain of Lactobacillus plantarum
TLDR
An amylolytic lactic acid bacterium identified as Lactobacillus plantarum was isolated from cassava roots during reting andufficient enzyme was synthesized and starch hydrolysis was not a limiting factor for growth.
Differences between Bacterial Communities in the Gut of a Soil-Feeding Termite (Cubitermes niokoloensis) and Its Mounds
TLDR
The findings confirmed that the soil-feeding termite mound (C. niokoloensis) represents a specific bacterial habitat in the tropics and revealed a drastic difference between the genetic structures of the bacterial communities of the termite gut and the mound.
Acquisition of phosphorus and other poorly mobile nutrients by roots. Where do plant nutrition models fail?
TLDR
Better mimicking natural ecosystems and exploiting plant diversity appears as an appealing way forward, on this long and winding road towards ecological intensification of agroecosystems.
