Nature Study suggests global decline in Intraspecific genetic diversity

The study has analyzed data spanning 3 decades and examined >600 species of animals, plants and fungi across terrestrial and marine ecosystems.

  • Genetic Diversity refers to the range of inherited traits within a species critical for a population to adapt to changing environments. It is essential for long-term survival of species populations and ensuring ecosystem resilience.

Key findings of the study

  • Extent of genetic loss: 2/3rd of studied populations experienced decline in genetic diversity, with less than half receiving any conservation management.
  • Impact Areas: Genetic loss occurred regardless of IUCN status and is not exclusive to rare and threatened species.
    • The loss of genetic diversity was high especially among birds and mammals.
  • Conservation Measures: Habitat restoration, disease control, captive breeding can help in reversing genetic loss.

Various Initiatives

  • Convention on Biological Diversity’s Kunming–Montreal Global Biodiversity Framework: It includes targets for safeguarding genetic diversity of all species.
  • In-situ Conservation: Protected Areas, National Parks etc. E.g. Project Tiger
  • Ex-situ Conservation: Zoological Parks, Gene Banks etc.
  • Technological Advancement: Environmental DNA (eDNA), Genome Sequencing, DNA Barcoding.

Conclusion

Maintaining genetic diversity safeguards biodiversity against future environmental changes and ensures the continued benefits that nature provides to society.
