Intrapopulation variation of Siberian stone pine cones and seeds quality in spaced planting plots

open access: yesFORESTRY BULLETIN, 2021
For Siberian stone pine (Pinus sibirica Du Tour), a valuable nut-bearing species, the development of a system of selectively significant signs of crop quality is relevant, which is necessary for the introduction of this species into culture. Were studied the level and nature of variability in the quality of cones and seeds in 32 trees on a 42-year-old ...

Repeatable Genomic Outcomes Along the Speciation Continuum: Insights From Pine Hybrid Zones (Genus Pinus)

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Hybridization is a widespread evolutionary process and a key source of evolutionary novelty. Despite intensive study, the extent to which hybridization is deterministic and repeatable, particularly in recurrent contact events involving the same species under varying ecological conditions, remains unclear. Here, we investigated three replicated
