Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.Climate change is projected to sharply reduce suitable habitats for eight endemic rupestrian plant species in Brazil's Iron Quadrangle. Ensemble niche models reveal species‐specific vulnerabilities and highlight climatic refugia and corridors that may support persistence.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae) [PDF]
American Journal of Botany, Volume 113, Issue 2, February 2026.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Repeated genetic adaptation under demographic limits in kiwifruit [PDF]
The Plant Journal, Volume 128, Issue 1, October 2026.SUMMARY Population genetic theory predicts that species with narrow geographic distributions experience stronger genetic drift, higher inbreeding, and greater mutational burden than their widespread relatives, yet how demographic history shapes the genomic basis of adaptation remains poorly understood.

Plant Reproductive Success Mediated by Nectar Offered to Pollinators and Defensive Ants in Terrestrial Bromeliaceae [PDF]
PlantsMost plants produce floral nectar to attract pollinators that impact pollination and seed production; some of them also secrete extrafloral nectar harvested by insects that may influence the plant reproductive success.
