Sentences with phrase «phenotypic plasticity»

Phenotypic plasticity refers to the ability of an organism to change its physical traits or characteristics in response to different environmental conditions. It means that an organism can adapt its appearance or behavior to better survive or thrive in various situations. For example, certain plants can adjust their leaf size or shape depending on the amount of sunlight they receive. Full definition

Although the two genomes of cells undergoing α - α unisexual reproduction are identical, phenotypic changes to these and other conditions (Figure S4) are clearly evident in even a relatively small sample of progeny produced by this process, which indicates that α - α unisexual reproduction generates phenotypic plasticity de novo since there is no preexisting genetic diversity to admix.
The majority of these studies report short - term (days, weeks or a few months, see [10]-RRB- «shock» responses that do not incorporate the longer - term potential for species gradual acclimatization (i.e. respond via phenotypic plasticity, see [11]-RRB- or adaptation (the selection of extant genetic variation that moves the average phenotype of a population towards the fitness peak).

This change in behaviour is an example of what scientists call phenotypic plasticity — the ability of an organism to respond to changes in their environment with adaptations to their physique, behaviour or life cycle.
Although diet - induced phenotypic plasticity has been documented in New World cichlids, it has been hypothesised that this type of plasticity would be limited in certain Old World cichlids, because of the morphological constraints on the jaw imposed by mouth - brooding.

As climate change advances, phenotypic plasticity could enable some species to remain in place and give others enough time to allow migration and adaptation to occur.

«Because climate change affects some environmental factors like precipitation and temperature but not others like day length, phenotypic plasticity could allow some species to persist in a habitat despite changing conditions and provide more time for them to evolve and migrate,» says co-author Zachariah Gezon, a Ph.D. student in Ecology and Evolutionary Biology at Dartmouth.
The Sequoiadendron canopy, from the American Journal of Botany article «Phenotypic plasticity of leaves enhances water - stress tolerance and promotes hydraulic conductivity in a tall conifer» by Alana R. O. Chin and Stephen C. Sillett.

These are the species that exhibit phenotypic plasticity, the generalists that can thrive in a wide range of environmental conditions and make use of different resources.
Phenotypic plasticity is an organism's ability to change in response to the environment, causing genetically identical organisms to look very different when they live in different conditions.
Our study suggests that the ability to undergo unisexual reproduction may be an evolutionary strategy for eukaryotic microbial pathogens, enabling de novo genotypic and phenotypic plasticity and facilitating rapid adaptation to novel environments.
