Evolutionary Significance of Phenotypic Plasticity in Plants
TLDR
This chapter focuses on evolutionary significance of phenotypic plasticity in plants, indicating that adaptation by plasticity is a widespread and important phenomenon in plants and has evolved differently in different species.Abstract:
Publisher Summary This chapter focuses on evolutionary significance of phenotypic plasticity in plants. The expression of an individual genotype is modified by its environment. The amount by which it can be modified is termed its plasticity. This plasticity can be either morphological or physiological; these are interrelated. The plasticity of a character is related to the general pattern of its development, and apart from this, that plasticity is a general property of the whole genotype. Plasticity of a character appears to be specific for that character, specific in relation to particular environmental influences, specific in direction, under genetic control not necessarily related to heterozygosity, and able to be radically altered by selection. Because plants are static organisms, plasticity is of marked adaptive value in a great number of situations. Examples of all these situations in plant species are discussed. They indicate that adaptation by plasticity is a widespread and important phenomenon in plants and has evolved differently in different species. The mechanisms involved in plasticity are varied. At one extreme, the character shows a continuous range of modification dependent on the intensity of the environmental stimulus. At the other, the character shows only two discrete modifications. The stimulus causing these modifications may be direct or indirect. The mechanisms found can be related to the particular environmental situation involved.read more

TL;DR: A conceptual model of the evolution of plant defense is concluded, in which plant physioligical trade-offs interact with the abiotic environment, competition and herbivory.

Adaptive versus non‐adaptive phenotypic plasticity and the potential for contemporary adaptation in new environments
TL;DR: It is concluded that adaptive plasticity that places populations close enough to a new phenotypic optimum for directional selection to act is the only Plasticity that predictably enhances fitness and is most likely to facilitate adaptive evolution on ecological time-scales in new environments.

Childhood Experience, Interpersonal Development, and Reproductive Strategy: An Evolutionary Theory of Socialization.
TL;DR: The concept of "reproductive strategy" drawn from the field of behavioral ecology is applied to the study of childhood experience and interpersonal development in order to develop an evolutionary theory of socialization in terms of 2 divergent development pathways.

TL;DR: These models utilize the statistical relationship which exists between genotype‐environment interaction and genetic correlation to describe evolution of the mean phenotype under soft and hard selection in coarse‐grained environments.

Phenotypic Plasticity and the Origins of Diversity
TL;DR: Much recent progress has been made toward integrating developmental and evolutionary biology, especially in vertebrate morphology, developmental genetics, and molecular biology, though an unfortunate one because it seems to imply that the main effect of developmental constraints is that of "Developmental constraints".
