In three wet-meadow herbs (Scorzonera humilis, Oenanthe peucedanifolia, and Lychnis flos-cuculi), landscape connectivity and plant community diversity are largely decoupled from intraspecific genetic diversity.
- Why it matters: Habitat connectivity’s role in linking plant species diversity to within-species genetic diversity is unclear, especially whether ecological heterogeneity and co-occurrence produce consistent co-variation.
- What they did: The study combined species distribution modelling, resistance-to-movement mapping, landscape connectivity analysis, and population genomics to test diversity patterns across the three species and their surrounding plant communities.
- The result: Connectivity metrics explained genetic diversity only in O. peucedanifolia, while genetic diversity in two species varied with presence of some community species yet remained consistently unrelated to local plant community diversity.
