• Sommario/riassunto: The general theme is being based around the ongoing European Science Foundation SIZEMIC Research Network, which has been running for several years. The network has focused on the role of body size in ecosystems and embraces a wide remit that spans all ecosystem types and a range of disciplines, from theoretical to applied ecology. Updates and informs the reader on the latest research findingsWritten by leading experts in the fieldHighlights areas for future investigation
