Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not b… Web10. sep 2014 · The analysis of phenotypic change is important for several evolutionary biology disciplines, including phenotypic plasticity, evolutionary developmental biology, …
WebPhenotypic variation is an important adaptive mechanism in rotifers, but has posed difficult problems for systematists. This variation arises by several mechanisms including cyclomorphosis, dietary- and predatorinduced polymorphisms, polymorphisms in hatchlings from resting eggs, and dwarfism.
