Conover and Schultz (1995) used reciprocal transplant experiments with the Atlantic silverside (Menidia menidia) to test whether countergradient variation in growth and size (faster growth and larger individuals in cooler northern regions) was due to phenotypic plasticity
in response to variable environmental conditions.
(10) Sex change in teleost fish offers a dramatic example of environmentally cued phenotypic plasticity
unprecedented in any other group of vertebrates.
While genetic differences are also bound to influence the evolution of phenotypic plasticity
, ecophenotypic variation in gastropod shells in response to multiple predators may explain geographic and temporal variation in shell morphology (Appleton and Palmer, 1988; Palmer, 1990).
The degree to which these phenotypic responses represent adaptive evolution or phenotypic plasticity
remains an active area of investigation, with evidence for both evolution and plasticity found in several studies (reviewed in ).
(2004) Predator-induced phenotypic plasticity
in organisms with complex life histories.
However, understanding the complete impact of climate change-induced coat colour mismatch on hare demography requires a detailed understanding of the potential for phenotypic plasticity
or microevolution in the phenology of coat colour moults in the species.
Goal of this research was to recognize variations in chromosomal stoichiometry especially of complete ploidal change between specimens, within specimens and between cells within specimens of the species Girardia schubarti (Marcus, 1946), any tendencies those variations might present and any relations they might have with selected components of phenotypic plasticity

of penis morphology and delayed reproductive maturation in response to male competition in waterfowl."
has been defined as the ability of a single genotype to produce more than one alternative morphological form in response to environmental conditions (1).
Adaptive phenotypic plasticity
(the ability of a single genotype to change its phenotype in res ponse to environment cues) is often key to optimizing crypsis in animals whose habitat is heterogeneous through space or time (Umbers et al.
