Abstract: Size-based analyses, where body size rather than species identity is the principle descriptor of an individual’s life history and role in the food web, can provide insights into productivity, sensitivity and community interactions that complement those from species based analyses. In this seminar, I describe recent developments in methods of size-based analysis, their strengths and weaknesses and their role in assessing the effects of fishing and climate change.
