Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] 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 be ...
Phenotypic plasticity can be seen in many organisms, one species that exemplifies this concept is the seed beetle Stator limbatus. This seed beetle reproduces on different host plants, two of the more common ones being Cercidium floridum and Acacia greggii .
Phenotypic plasticity is the ability of an individual organism to alter its behavior, morphology and physiology in response to changes in environmental conditions. [1] Root phenotypic plasticity enables plants to adapt to an array of biotic and abiotic constraints that limit plant productivity. Even though the exploitation of soil resources ...
Example of phenotypic plasticity in the desert locust Schistocerca gregaria. The green pigment locust (top) has miniature wings that result from a low-density population. The deep pigmentation locust (bottom) has leg and wing development suitable for migration, which arose due to a high-density environment. [2]
For example, crocodiles possess a temperature-dependent sex determining polyphenism, where sex is the trait influenced by variations in nest temperature. [ 3 ] When polyphenic forms exist at the same time in the same panmictic (interbreeding) population they can be compared to genetic polymorphism . [ 4 ]
Plants display the most obvious examples of ecophenotypic variation. One example are trees growing in the woods developing long straight trunks, with branching crowns high in the canopy, while the same species growing alone in the open develops a spreading form, branching much lower to the ground.
Temporal plasticity is considered adaptive if the phenotypic response results in increased fitness. [3] Non-reversible phenotypic changes can be observed in metameric organisms such as plants that depend on the environmental condition(s) each metamer was developed under. [1]
The authors considered three biological phenomena that are often considered to be either irrelevant to evolution, or absent because “forbidden” namely, i) role of phenotypic plasticity and developmental canalization, ii) reverse flow of information from phenotype to genotype (or its absence), and iii) conditions under which direct ...
