The Ribosomal Database Project is running a user survey on habitat terms that are most important to users. Click on the RDP website and the quick survey will automatically launch in your browser: http://rdp.cme.msu.edu
The survey is part of the Habitat-Lite initiative within the Genomic Standards Consortium (GSC). Habitat-Lite is a small set of high-level terms for describing the habitat of biological samples, particular selected to cover genomes, metagenome, 16/18S sequences and related molecules. All Habitat-Lite terms are taken from the much larger Environment Ontology (http://environmentontology.org).
A paper on Habitat-Lite will appear as part of the special issue of OMICS to come from the 5th GSC workshop. A online version can be seen here: Pubmed
