1. Defence on Demand : A physiological perspective on phenotypic plasticity in anti-predator traits
Abstract : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. READ MORE

2. Plant Inducible Responses to Damage: Evolution and Ecological Implications
Abstract : Abstract Inducible plant responses to damage, i.e. inducible defence responses and compensatory growth responses, are theoretically examined in an evolutionary and ecological context. Inducible defences are generally considered to be beneficial under conditions of low risk of herbivory and when initial damage is moderate. READ MORE

3. The prey perspective - behaviour and appearance in a world of predators
Abstract : The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. READ MORE

4. Causes and consequences of individual variation in anti-predator traits
Abstract : Predation imposes a potent evolutionary force on prey, moulding the evolution of traits and diversification of species, and can furthermore have powerful ecological consequences. We know that different species vary in how they cope with their natural enemies, and, consequently, a huge range of anti-predator defences are displayed in nature. READ MORE

5. Phenotypic plasticity and local adaptation in tadpoles
Abstract : Amphibian larvae are plastic in many traits. Can plasticity buffer population divergence, so that local adaptation is more common in non-plastic traits? I argue that this may be the case for adaptive plastic responses. READ MORE
