Eco-evolutionary dynamics are well studied but the term is applied to a wide variety of effects and interactions. Yet comparing these different types of studies on eco-evolutionary dynamics will inform on how this field can move forward, which is precisely the aim of a recent British Ecological Society cross-journal Special Feature. Here I discuss a study published within this Special Feature that investigates how an eco-evolutionary feedback loop between population dynamics and fighter expression affects the evolution of alternative reproductive tactics.
Over the last century, a predominant number of biological investigations utilized either model systems or laboratory populations for experimentation. While model organisms are extensively studied from diverse perspectives (genetics, behaviour, life-history, etc.) it would be imprudent to assume new organism-oriented discoveries are behind us. Most recently, Stewart et al. (2018) revealed the existence of a new male type in the laboratory model organism, the bulb mite Rhizoglyphus robini.
