Scientists of the Genetic Resources Centre of LSFRI "Silava" in collaboration with colleagues from other European research institutions, have co-authored the article Global meta-analysis shows action is needed to halt genetic diversity loss, which has been published in the journal Nature.
The conservation of genetic diversity is a global priority. To preserve genetic diversity within species, it is essential to identify potential threats, develop conservation strategies, and study how genetic diversity changes over time.
As part of an international research effort involving more than 50 scientists from over 20 countries — including representatives from LSFRI "Silava" for Latvia — a global meta-analysis was conducted to assess and improve the implementation of genetic diversity monitoring. The study reviewed over 80,000 scientific publications, from which 882 were selected for in-depth analysis. The final dataset included over 30 years of research on 628 species (animals, plants, fungi, and chromists) across 141 countries.
The extensive study concluded that, over time, genetic diversity is declining in two-thirds of the species populations analyzed, primarily due to various threats. Moreover, fewer than half of these populations have conservation measures in place. The findings highlight the urgent need to implement existing genetic conservation strategies to improve environmental conditions, support population growth, and introduce new individuals into populations — ultimately to preserve or even enhance genetic diversity.
Additionally, it is crucial not only to maintain but also to expand genetic diversity monitoring programs to ensure timely and accurate data on genetic changes.
The research was carried out within the framework of the COST Action CA18134 Genomic Biodiversity Knowledge for Resilient Ecosystems (G-BiKE).
