THE EVOLUTION OF PHENOTYPIC PLASTICITY IN BUTTERFLIES
Phenotypic plasticity is the ability of an organism to have distinct phenotypes in response to environmental cues. Early work in insects implicated changes to hormone titers as key molecular mediators of plasticity, but details on how the environment alters the development of traits via these …

Phenotypic Plasticity of Oral Jaw Dentition in Archosargus Probatocephalus
<p>Phenotypic plasticity, the capacity of a single genotype to exhibit variable phenotypes in different environments, is common in many species. A sample of wild caught <i>Archosargus probatocephalus</i>, also known as sheepshead, from Florida was randomly divided into two treatment groups: one …

Phenotypic plasticity from a predator perspective: empirical and theoretical investigations
Phenotypic plasticity is common in predator-prey interactions. Prey use inducible defenses to increase their chances of survival in periods of high predation risk. Predators, in turn, display inducible offenses (trophic polyphenisms) and adjust their phenotypes to the prevailing type of prey. In …

Patterns and mechanisms of phenotypic plasticity in poison frog tadpoles
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-08-01

Evolutionary trade-offs and adaptive phenotypic plasticity under multidimensional selective pressure
… of mutations and shapes traits directly through phenotypic plasticity. Moreover, the ability of plasticity to allow a single genotype to thrive in multiple environmental conditions could provide an important mechanism for the evolution of generalists. Predicting evolutionary dynamics will require …

THE ECOLOGICAL IMPORTANCE AND EVOLUTIONARY POTENTIAL OF PHENOTYPIC PLASTICITY IN NOVEL ENVIRONMENTS
<p>Phenotypic plasticity refers to a genotype’s ability to produce different phenotypes in response to different environments. How organisms respond to environments through phenotypic plasticity can impact the fitness of individuals and thus the demography and even evolution of a population. Having …

Phenotypic plasticity and population differentiation in Suaeda maritima on a salt marsh
… main aim of this study has been to examine the phenotypic variations within and between its populations in the heterogeneous microenvironments of a salt marsh. Detailed field characterizations of the growth, seed production and seed heteromorphism of four Suaeda maritima populations at Stiffkey …

Genetic connectivity, adaptation, and phenotypic plasticity of corals and anemones under thermal stress
… selection and adaptation across generations to phenotypic plasticity within a single individual’s lifespan. In this context, I explore three case studies of thermal stress in corals and anemones. I begin with massive Porites lobata corals from the central Pacific. Here, reefs that are most …

Exploring the role of auxin in phenotypic plasticity in Arabidopsis thaliana root development
Auxin is a plant hormone that positively regulates the initiation and emergence of lateral roots. In this study we used several approaches to reduce auxin transport moving either from the shoot toward the root apex or from the root tip toward the base and examined the effect of these treatments on …

Phenotypic Plasticity in Economically and Ecologically Important Bivalves in Response to Changing Environments
… I seek to investigate if higher degrees of phenotypic plasticity and parental carryover will have the potential to improve bivalve’s fitness and tolerance as climate change progresses. My goal is to evaluate plastic capacity by taking a multi-method approach to assessing the physiological …

Increased phenotypic plasticity linked to broader geographic range size in sunflower (Helianthus) species
… spp.). In a garden experiment, we compared the phenotypic plasticity of five Helianthus species representing different geographic ranges. Locally restricted H. longifolius and H. verticillatus showed less plasticity in growth and allocation traits than widespread H. angustifolius and H. …

Exploring Eastern Musk Turtle (Sternotherus odoratus) Population Dynamics and Phenotypic Plasticity in Comal Springs, Texas
… may be driving morphological changes through phenotypic plasticity and highlight the capacity for freshwater turtles to adapt to novel ecological pressures.

Phenotypic plasticity in Mercurialis annua : the role of signal detection and response in sex determination
Mercurialis annua has been found to show phenotypic plasticity in terms of their sexual strategies. In androdioecious populations (males coexisting with cosexes), genetically labile males function as cosexes at low densities. At high densities, the frequency of males increases, while cosexes …

Phenotypic Plasticity of Native and Invasive Cool-Season Grasses in Response to Frequency of Moisture Availability
<p>Phenotypic plasticity, the ability of an individual to alter its growth in response to environmental conditions, is an attribute that is considered a likely invader attribute, as it provides the opportunity to expand its ecological niche breadth. Adaptive phenotypic plasticity can affect not …

Molecular mechanisms of phenotypic plasticity: Explorations of DNA methylation and transcriptional regulation using the honey bee
Honey bee behavioral maturation exemplifies phenotypic plasticity, the ability of a single genotype to produce multiple phenotypes in response to environmental conditions (Scheiner, 1993; West-Eberhard, 1989). Behavioral maturation in honey bees is characterized by a socially regulated transition …

Phenotypic plasticity in soybeans (glycine max (l.) merrill) associated with plant density and phenological stage at thinning
… (Glycine max L.) is reported to demonstrate plasticity responses when exposed to either supra or sub optimal plant density stress. However, it is not known whether determinate and indeterminate varieties respond the same and at what phenological stage a soybean plant is able to exhibit …

Environment-induced Phenotypic Plasticity in the Teeth of Hatchery and Wild Largemouth Bass, <i>Micropterus floridanus</i>
… anatomy, and behavior. With fishes being highly phenotypically plastic, the potential exists for all aspects of hatcheryreared fish to vary significantly from their wild counterparts while having potentially adverse effects on their survival after release. Previous analyses have demonstrated …
