Polytraits Database

Polytraits is a database on biological traits of bristle worms (Polychaeta). The database contains 47 different traits describing the morphological, behavioural, reproductive and larval features as well as the environmental affinities of a taxon. Each trait has several sub-categories, so-called modalities. In total, 252 modalities are covered. The expression of a trait in a taxon is coded in the database by declaring each modality as present or absent.

Each assignment of a modality (and its presence/absence value) to a taxon is connected to a literature reference. This assignment is mandatory, no data can be entered without specifying the source of the data; however, to capture undocumented knowledge, the option "Expert's opinion" can be specified. Additionally, most records are accompanied by the quotation of the exact literature passage which has led to the coding of the information.
