Understanding the processes involved in evolution of organisms is a principal topic that has received much attention from the research community. A common way to achieve this is to study the ecological conditions and morphological relationships of taxa. Fish are widely regarded as notable animal models in studies of environmental influence on morphological features given their high environmenta...

The ability of individual organisms to alter morphological and life-history traits in response to the conditions they experience is an example of phenotypic plasticity which is fundamental to any population's ability to deal with short-term environmental change. We currently know little about the prevalence, and evolutionary and ecological causes and consequences of variation in life history pl...
