How transfer the biodiversity knowledge to society? Here I show several ways used by the BOS Arthropod Collection of the University of Oviedo to open the biodiversity data associated to specimens deposited in the Collection to society. Primary biodiversity data are released through local GBIF IPT, GBIF metadata repository and data-portal, Collection website and data-papers (one for each digitisated subcollection). Moreover, scientific publications are deposited, when possible, in the institutional repository of the University (RUO), data are included in open access conservation works & monographies, communicated in scientific congress and the presentations shared in internet. Several divulgative articles about BOS Collection or some taxonomical groups have been wrote, colaborations with newspapers, and dissemination of scientific results, biodiversity data, conservation issues and other biodiversity topics posted in social networks in the Collection profiles.
