New scientific publication in Forests by LIFE STEMMA ATHOS

A significant scientific study titled Genetic Diversity and Population Structure of Black Pine (Pinus nigra Arn.) in Mt. Athos, Northern Greece was recently published in the journal Forests (16 (9):1399, DOI: 10.3390/f16091399) on 1 September 2025. The study was elaborated in the framework of the LIFE STEMMA ATHOS project, examines the genetic diversity and structure of four black pine (Pinus nigra) populations in northern Greece, with a focus on the Athos peninsula.

The findings reveal that Mount Athos functions as a vital genetic reservoir for the species, hosting the population with the highest genetic diversity. In contrast, isolated populations such as Perama (Evros) exhibit significant genetic erosion due to bottleneck effects.

The observed genetic differentiation within the Athos region underscores the importance of targeted conservation and restoration strategies, such as enhancing gene flow and using local genetic material for reforestation. The study is especially relevant in the context of climate change adaptation, as genetically diverse populations are more resilient and better equipped to respond to environmental stresses.
