Mammalian Biology (formerly Zeitschrift für Säugetierkunde) is an international scientific journal edited by the Deutsche Gesellschaft für Säugetierkunde (German Society of Mammalogy). The journal is devoted to the publication of research on mammals. Its scope covers all aspects of mammalian biology, such as anatomy, morphology, palaeontology, taxonomy, systematics, molecular biology, physiology, neurobiology, ethology, genetics, reproduction, development, evolutionary biology, domestication, ecology, wildlife biology, conservation biology, and the biology of zoo mammals.

To qualify for publication, a manuscript must contribute to the understanding of mammalian biology by presenting either new and original research data (as a full article or in short communication format) or a thorough review of a particular topic of mammalogical research. Investigations using mammals merely as models or emphasizing experimental or veterinary aspects are of interest only if they are of substantial relevance to mammalogists. Studies testing explicitly formulated hypotheses are preferred to those presenting primarily descriptive results.

At present, one volume consisting of six issues is published each year. Due to its wide range of topics, Mammalian Biology is primarily of interest to scientists working on the listed various fields of mammalogy but also to biologists and zoologists in general as well as to veterinarians and medical scientists.
