Acclimation and plasticity are two closely related concepts in biology. Acclimation refers to the physiological process by which an organism adjusts to a new environment, often in response to short-term changes. On the other hand, plasticity is an organism's ability to exhibit different traits or characteristics in response to environmental changes, which can be sustained over long periods, potentially spanning multiple generations. While acclimation is a form of phenotypic plasticity, the latter also encompasses broader changes in behaviour, morphology, and physiology.

Acclimation is a special case of phenotypic plasticity
Acclimation and plasticity are distinct but related concepts. Acclimation refers to a physiological process through which an organism adapts to a new environmental circumstance. It is a short-term response that is easily reversible. For example, young salmon undergo physiological changes that allow them to migrate from freshwater rivers to the sea, adapting to the change in salinity. When they return to freshwater to reproduce, they revert to their original state.
Phenotypic plasticity, on the other hand, refers to changes in an organism's behavior, morphology, and physiology in response to a unique environment. It is an evolutionary adaptation to environmental variations that occur within an individual organism's lifespan. Phenotypic plasticity can be influenced by both genetics and the environment. For instance, the shape of leaves on a plant can be determined by genetics, but it can also change based on environmental factors like light and humidity.
While acclimation and plasticity are distinct, they are related in that acclimation can be considered a special case of phenotypic plasticity. Acclimation is a type of physiological plasticity, and it can lead to more sustained forms of plasticity. When an organism experiences acclimation over an extended period, it may develop modified external features or structures that better adapt it to the new environmental circumstances. This can become evident not only at the physiological level but also at morphological levels.
For example, thermal acclimation in ectothermic organisms, such as freshwater snails, involves phenotypic adjustments to maintain cell function across temperatures. These adjustments are essential, as all aspects of their physiology are directly dependent on their thermal environment. As another example, acclimatizing animals to high-protein diets can increase the activity of aminopeptidase-N, which is an enzyme that digests proteins.
In summary, acclimation is a rapid and reversible phenotypic modification that allows an organism to adapt to new environmental circumstances. Phenotypic plasticity is a broader concept that encompasses all types of environmentally induced changes that may or may not be permanent throughout an individual's lifespan. Acclimation is a specific type of physiological plasticity that can lead to more sustained forms of plasticity, making it a special case of phenotypic plasticity.

Acclimation is a short-term adaptation to a new environment
Phenotypic plasticity is the ability of a single genotype to generate a range of phenotypes in response to environmental changes. It is a fundamental mechanism of phenotypic plasticity that is essential for population persistence in changing environments. It can be induced during early development, with persistent effects on adult phenotypes, and it can also occur reversibly throughout life, which is known as acclimation.
Acclimation is easily reversible and mostly occurs at the physiological and metabolic levels. For example, thermal acclimation in response to temperature changes can involve adjustments in the lipid composition of cell membranes to maintain membrane fluidity, which is critical for cell function. Acclimation can also involve changes in the digestive system to respond to dietary changes, such as an increase in the activity of enzymes that digest specific nutrients.
The distinction between acclimation and plasticity lies in the timespan and the level of change. Acclimation is a rapid, short-term response to environmental changes, while plasticity can be sustained over longer periods, even spanning filial generations. Plasticity results in more permanent changes, including the appearance of modified external features or structures that are better adapted to the new sustained environment.
It is important to note that the relationship between acclimation and plasticity is complex and intertwined. Acclimation can be considered a form of plasticity, particularly when it is sustained over time. Plasticity, on the other hand, can be viewed as an extension of acclimation, as it involves more profound and lasting changes that provide a survival advantage in the new environment.

Plasticity is an extension of acclimation over a sustained period
Acclimation and plasticity are two related concepts. Acclimation refers to a physiological process—a short-term adaptation to a new environmental circumstance, which is easily reversible. Phenotypic plasticity, on the other hand, refers to changes in an organism's behaviour, morphology, and physiology in response to a unique environment. It can be induced during early development and have persistent effects on adult phenotypes.
Acclimation is a special case of phenotypic plasticity. For example, thermal acclimation in ectothermic organisms is crucial as all aspects of their physiology are directly dependent on their thermal environment. Phenotypic plasticity can be observed in the digestive system of some animals, which can respond to changes in dietary nutrient composition, diet quality, and energy requirements.
The distinction between acclimation and plasticity lies in the timescale and the nature of the changes. Acclimation refers to rapid and reversible phenotypic modifications in response to environmental change. It is mostly physiological or metabolic. Plasticity, on the other hand, can be a longer-term process, spanning multiple generations, and can involve changes at the morphological level, with the appearance of modified external features or structures better adapted to the new sustained environmental circumstance.
Thus, plasticity can be viewed as an extension of acclimation over a sustained period. While acclimation is a short-term adaptation, plasticity involves more permanent changes that can be passed down to subsequent generations. This is evident in the example of young salmon, which undergo physiological changes to transform from freshwater fish to marine fish as they migrate from rivers to the sea. These changes are reversible as the salmon return to freshwater to reproduce, demonstrating the reversible nature of acclimation. However, if the new environmental circumstance is sustained over a longer period, plasticity can occur, with only those individuals who successfully develop modified features being naturally selected for survival.

Phenotypic plasticity is a response to unique environments
Acclimation and plasticity are related concepts. Acclimation refers to a physiological process and can be described as a short-term adaptation to a new environmental circumstance. It is easily reversible. On the other hand, plasticity is an extension of acclimation when the experience is sustained over a period of time, even spanning filial generations.
Phenotypic plasticity refers to the ability of a genotype to express different phenotypes depending on the environment in which it resides. It is the property of organisms to produce distinct phenotypes in response to environmental variation. It is fundamental to how organisms cope with environmental variation, encompassing all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be permanent throughout an individual's lifespan.
Phenotypic plasticity is, therefore, a response to unique environments. For example, genetically identical water fleas (Daphnia) clones can differ in their morphology depending on whether they are reared in the absence or presence of a potential predator. Many species adjust their phenology, the seasonal timing of life-cycle events, to ambient temperatures, with phenology being earlier under warm conditions.
Phenotypic plasticity can be induced during early development, with persistent effects on adult phenotypes, and it can occur reversibly throughout life (acclimation). For example, the southern rockhopper penguin exhibits phenotypic plasticity by expressing different strategies and foraging behaviours depending on the climate and environment.
Phenotypic plasticity is particularly important for immobile organisms such as plants. It allows plants to take in information from their environment and respond without changing their location.

Plasticity can be induced during early development
Acclimation and plasticity are related concepts. Acclimation refers to a physiological process—a short-term adaptation to a new environmental circumstance, which is easily reversible. Plasticity, on the other hand, is an extension of acclimation when the experience is sustained over a period of time, spanning filial generations.
Developmental plasticity refers to changes in neural connections during growth, influenced by environmental interactions and learning. Most of these connections form from birth to early childhood, following three main processes, with critical periods determining lasting changes. The term can also describe how an embryo or larva adjusts its traits based on the environment. Unlike phenotypic plasticity, which can be reversible in adulthood, developmental plasticity shapes traits early in life that usually remain permanent.
For example, in utero exposure to nicotine has been linked to adverse effects, such as severe physical and cognitive deficits due to the impediment of normal acetylcholine receptor activation. Similarly, higher exposure to androgens during prenatal and early postnatal life has been hypothesized to lead to increased plasticity in traits that display greater male variability.
In Anolis lizards, developmental plasticity is demonstrated through limb morphology, allowing them to adapt to different environmental conditions during their early development.
