Environmental Applications of Microorganisms01:30

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
Methods to Assess Microbial Communities01:19

Methods to Assess Microbial Communities

Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...
Dimensions of Health and Illness01:21

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
Gene-Environment Interactions01:20

Gene-Environment Interactions

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...
Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

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...

Area of Science:

  • Environmental Science
  • Molecular Biology
  • Ecotoxicology

Background:

  • Conventional biomarkers may not capture the full spectrum of organismal responses to environmental contaminants.
  • Omic technologies offer high-throughput, quantitative monitoring of biological molecules, providing a broader assessment of contaminant effects.
  • Integrating multiple omic approaches is crucial for understanding complex ecosystem responses.

Purpose of the Study:

  • To propose a working scheme for combined transcriptomic and proteomic methodologies in environmental biomonitoring.
  • To address challenges in applying omics to non-model organisms used as bioindicators.
  • To evaluate the utility of omics in assessing pollution impacts.

Main Methods:

  • Transcriptomic analysis using heterologous microarrays in *M. spretus*.
  • Transcriptomic analysis using suppressive subtractive hybridization (SSH) in *P. clarkii*.
  • Proteomic analysis, including two-dimensional gel electrophoresis (2-DE), to assess protein expression changes.

Main Results:

  • Animals exposed to heavy pollution showed enhanced immune responses and/or cell apoptosis.
  • Proteomic data provided a holistic view of pollution-induced protein intensity shifts, complementing transcriptomic findings.
  • Sediment element concentrations correlated with protein expression changes in *C. maenas* crabs.

Conclusions:

  • Combined omic approaches are valuable tools for environmental biomonitoring.
  • Omics facilitate the characterization of biological responses to diverse environmental contaminants.
  • These technologies are essential for identifying and addressing contamination threats in ecosystems.
