Coriaria nepalensis , a nitrogen-fixing actinorhizal shrub, is prominent and successful colonizer of bare rocks landslide affected degraded lands. Field experiments were conducted to determine the differences in biomass decomposition nutrient release pattern different plant parts C. using litter bag technique. Results showed that leaves decomposed completely within 6 months while only 46.55% la...

This commentary examines an "inconvenient truth" that phosphorus (P)-based nutrient mitigation, long regarded as the key tool in eutrophication management, in many cases has not yet yielded the desired reductions in water quality and nuisance algal growth in rivers and their associated downstream ecosystems. We examine why the water quality and aquatic ecology have not recovered, in some case a...

During the twentieth century, agricultural production strived to achieve increased food production in order to satisfy both local and export demands. In many cases, this led to increased farm sizes and an operational separation of crop and livestock production. Society fears that the trend of increasing centralization and industrialization of agriculture, specifically animal agriculture, has re...

N,N-Dimethyldithiocarbamate (DMDTC) is a typical precursor of N-nitrosodimethylamine (NDMA). Based on separate hydrolysis, sorption and biodegradation studies of DMDTC, a laboratory-scale anaerobic-anoxic-oxic (AAO) system was established to investigate the removal mechanism of DMDTC in this nutrient removal biological treatment system. DMDTC hydrolyzed easily in water solution under either aci...

Plants accommodate a specific microbiota on and in their roots that, similar to the microbial communities in human or animal guts, supports the host in nutrient acquisition (1). Beneficial associations with fungi are widespread in the plant kingdom and probably best known are so-called mycorrhizal symbioses (Fig. 1), which are formed between soil fungi and ∼90% of land plants (2). In these part...

The changes in diatom species composition in a sediment core from Crevice Lake, Yellowstone National Park, spanning the past 2550 yr, were used to reconstruct long-term limnological and ecological conditions that may be related to late Holocene climate variability. Planktic forms dominate the fossil diatom assemblages throughout this record, but changes in species dominance indicate varying nut...

Iron deficiency (ID) is a common nutrient deficiency worldwide. This condition is linked to changes in myelin formation, dopaminergic function, and energy metabolism. Early ID results in persistent long-term cognitive and behavioral disturbances in children, despite a return to normal iron status. The present study assesses formerly ID adult rats on maze learning tasks that depend on specific b...
