Acta Zoologica Bulgarica publishes original research articles, reviews and short communications in systematics and phylogenetics, zoogeography and faunistics, terrestrial ecology and behaviour, aquatic ecology, parasitology, palaeozoology, zoomorphology and developmental biology, conservation biology, applied zoology and other branches of zoology dealing with diversity, ecology and evolution of animals. The geographical scope of the journal is worldwide but a priority is given to the Bulgarian and Balkan fauna as well as the fauna of associated regions (e.g. Black Sea, Danubian Basin, Southeast Europe). Descriptions of new zoological methods, short reviews or annotations of zoological books and information about scientific events (past or forthcoming) are also accepted.
