Nitrogen (N) availability is increasing in many ecosystems due to anthropogenic disturbance. We used a nucleotide analog technique and sequencing of ribosomal RNA genes to test whether N fertilization altered active fungal communities in two boreal ecosystems. In decaying litter from a recently burned spruce forest, Shannon diversity decreased significantly with N fertilization, and taxonomic r...

WordNet and HowNet are large-scale lexical resources that adopt complementary perspectives toward semantic representation. WordNet is differential, inasmuch as it provides a rich taxonomic structure but little in the way of explicit propositional content. HowNet is constructive, and dedicates its representational energies to the explicit definition of relational structures for each lexico-conce...
