Journal of Experimental Biology is the leading journal in comparative animal physiology. It publishes papers on the form and function of living organisms at all levels of biological organisation, from the molecular and subcellular to the integrated whole animal. It plays a major role in increasing cross-fertilisation of techniques and knowledge across specialisation boundaries. Our authors and readers reflect a broad interdisciplinary group of scientists who study molecular, cellular and organismal physiology in an evolutionarily and environmentally based context. Journal of Experimental Biology is published twice monthly (24 issues/year).
