In this Research Round Table episode we discuss three recent research papers from within the institute: a paper by James Grecian and colleagues examining sex-based differences in foraging behaviour in gannets; a study by Who-Seung Lee, Pat Monaghan, and Neil Metcalfe studying the costs of rapid growth in sticklebacks; and a paper by Annabelle Haudry, Barbara Mable and colleagues investigating the consequences of self-fertilization for genetic diversity in plants.
