Caldasia is a quarterly peer-reviewed open access scientific journal published by the Instituto de Ciencias Naturales (Universidad Nacional de Colombia) since 1940. Articles are written in Spanish or English. The journal covers biodiversity topics in a wide sense, including the documentation, understanding, or conservation of biological diversity and thus accepts papers on botany, zoology, ecology, biodiversity, biogeography, taxonomy, systematics, conservation, anthropology, and related disciplines. It publishes full papers, reviews, or short communications. The journal charges no publication fees to authors.
