Environmental variability greatly influences the eco-evolutionary dynamics of a population, i.e. it affects how its size and composition evolve. Here, we study a well-mixed population of finite and fluctuating size whose growth is limited by a randomly switching carrying capacity. This models the environmental fluctuations between states of resources abundance and scarcity. The population consi...

Extended Producer Responsibility (EPR) legislation focuses on the life-cycle environmental performance of products and has significant implications for management theory and practice. In this paper, we examine the influence of EPR policy parameters on product design and coordination incentives in a durable product supply chain. We model a manufacturer supplying a remanufacturable product to a c...

1. Understanding an animal’s ecology requires knowledge of how individual variation in behaviour and physiology interact with each other and with the environment that an animal experiences. 2. Environmental variation affects behaviour, but whether individual variation in physiological performance also affects behaviour is poorly known. 3. We studied a high-altitude population of Deer Mice ( Per...
