Researchers in communication technology and a number of biological and environmental sciences show how semantic technology can deal with the vast heterogeneity of studies about biodiversity in a wide range of fields using very different theories and methodologies. In sections on linked biodiversity data, biodiversity ontologies, and novel insights through applications, they consider such topics as linked open data for biodiversity, semantic phenotypes, the biocollections ontology, an ontology for fish reproduction, the large-scale study of prokaryotic phenotypes, and the semantic analysis of traits and genes.
