1. 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

2. Phenotypic Processes Triggered by Biological Invasions
Abstract : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. READ MORE

3. Phenotypic plasticity and local adaptation in island populations of Rana temporaria
Abstract : Phenotypic plasticity is the ability of a genotype to express different phenotypes in different environments. Despite its common occurrence, few have investigated differences in plasticity between populations, the selection pressures responsible for it, and costs and constraints associated with it. READ MORE

4. 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

5. Intraspecific divergence and phenotypic plasticity in behavioural profiles of teleost fish
Abstract : Behavioural differences between and within individuals can greatly affect the outcome of behavioural studies. In addition, behavioural interactions between individuals can compromise the health and welfare of captive fish. READ MORE
