Convergent Evolution

33.9K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Summary
This summary is machine-generated.

Marine microbes and dissolved organic matter (DOM) show seasonal patterns. Microbial communities are less predictable year-to-year than DOM, suggesting functional redundancy stabilizes ocean chemistry.

Area of Science:

  • Marine microbial ecology
  • Biogeochemistry
  • Oceanography

Background:

  • The marine dissolved organic matter (DOM) pool is a vast carbon reservoir crucial for global carbon flux.
  • Understanding microbe-molecule interactions within the DOM pool is essential but remains challenging.

Purpose of the Study:

  • To investigate the coupling between prokaryoplankton community composition and DOM molecules.
  • To analyze temporal patterns in DOM composition and microbial taxa over three years.

Main Methods:

  • Integration of a 3-year, depth-resolved molecular time series of DOM.
  • Parallel taxonomic characterization of prokaryoplankton.
  • Analysis of temporal coordination and periodicities in DOM molecules and microbial taxa.

Main Results:

  • Approximately 40% of both DOM molecules and microbial taxa exhibited 12-month periodicities, indicating high temporal coordination.
  • Interannual patterns in DOM composition were more predictable than those of microbial communities.
  • Functional redundancy in microbial metabolism may stabilize ocean chemistry.

Conclusions:

  • Microbial processes play a significant role in regulating marine DOM composition.
  • Functional redundancy among microbial taxa contributes to the stability of ocean chemistry.
  • The findings provide a framework for improving biogeochemical models by incorporating microbial dynamics.
