Biology Letters

Aims & Scope

Previously a supplement to Proceedings B, and launched as an independent journal in 2005, Biology Letters is a primarily online, peer-reviewed journal that publishes short, high-quality articles, reviews and opinion pieces from across the biological sciences.

The scope of Biology Letters is vast - publishing high-quality research in any area of the biological sciences.

However, we have particular strengths in the biology, evolution and ecology of whole organisms.

We also publish in other areas of biology, such as molecular ecology and evolution, environmental science, and phylogenetics.
