Central European Journal of Biology (CEJB) is an international journal that publishes research results in all biology fields. The aim of this journal is to become the premier source of high quality research from Central and Eastern Europe. Also, we assist researchers from Central and Eastern Europe and from other regions where English is not the mother tongue, e.g. native English speaking researchers polish up the language of articles submitted to CEJB. Nevertheless, contributions from other parts of the world are by no means excluded. All authors receive very fast and comprehensive peer-review. Additionally, every published article is promoted to researchers working in the same field. The CEJB is peer-reviewed and is published quarterly in paper and electronic version. The language of the CEJB is English. CEJB will feature research articles, rapid communications, reviews, minireviews, report and guest commentaries, letters to the editor and book reviews.
