Functional Groups

91.8K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Area of Science:

  • Marine Biology
  • Zooplankton Ecology
  • Functional Trait Analysis

Background:

  • Copepods are vital zooplankton in marine ecosystems, influencing food web dynamics.
  • Understanding functional traits of Mediterranean copepods is crucial for assessing ecosystem health.
  • Previous research has not comprehensively analyzed the functional diversity of this key group.

Purpose of the Study:

  • To compile and analyze functional traits of representative Mediterranean copepod species.
  • To identify distinct ecological roles and functional groups within Mediterranean copepods.
  • To provide a foundation for future ecological and conservation studies.

Main Methods:

  • Database creation for 191 Mediterranean copepod species.
  • Inclusion of 7 key functional traits: body length, trophic group, feeding type, spawning strategy, diel vertical migration, and vertical habitat.
  • Application of cluster analysis in the functional trait space.

Main Results:

  • A comprehensive database of Mediterranean copepod functional traits was established.
  • Cluster analysis successfully separated copepod species into distinct functional groups.
  • These groups represent diverse ecological roles within the Mediterranean Sea.

Conclusions:

  • Mediterranean copepods display significant functional diversity.
  • Functional trait analysis reveals distinct ecological niches occupied by different copepod groups.
  • This classification aids in understanding copepod contributions to ecosystem functioning and resilience.
