Summary
Organism development is shaped by genetics and environment, including parental effects. Understanding adaptive phenotypic plasticity requires clear hypotheses and experimental data, particularly in birds.
Area of Science:
- Developmental biology
- Evolutionary biology
- Ecology
Background:
- Phenotypic development arises from genetic and environmental interactions.
- Environmental influences include direct and indirect (parental) effects, potentially shaping offspring for future conditions.
- Adaptive phenotypic plasticity is crucial for organism survival and reproduction.
Purpose of the Study:
- To clarify paradigms, predictions, and experimental needs for studying direct and indirect environmental effects on phenotypic development.
- To examine the role of endocrine systems in mediating environmental influences on development.
- To identify knowledge gaps in avian developmental plasticity.
Main Methods:
- Review and synthesis of existing research paradigms in developmental plasticity.
- Focus on avian studies, integrating mechanistic and functional approaches.
- Analysis of experimental data requirements for hypothesis testing.
Main Results:
- Environmental influences can constrain development or promote adaptive plasticity.
- Endocrine systems are likely key mediators of environmental effects on phenotype.
- Distinguishing adaptive responses requires careful experimental design and hypothesis elucidation.
Conclusions:
- Further research is needed to fully understand the adaptive significance of developmental responses to environmental factors.
- Experimental manipulations are essential to validate theoretical frameworks.
- Avian models offer valuable insights into phenotypic plasticity, but broader application is possible.

01:10Nature and Nurture
19.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

19.9K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

02:27Background and Environment Affect Phenotype
5.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

1.4K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Microorganisms inhabit highly localized spaces known as microenvironments, which are defined by distinct physical and chemical characteristics. These include oxygen concentration, pH, temperature, light availability, and nutrient levels. The conditions within a microenvironment can differ markedly from those in the surrounding area and significantly influence microbial growth, metabolism, and community structure.Microenvironments often display sharp physicochemical gradients over small spatial...
