Micropropagation enables the mass propagation and conservation of Dyckia distachya Hassler [PDF]

Crop Breeding and Applied Biotechnology, 2005
The Atlantic Forest has a rich biological diversity and elevated levels of endemism in which bromeliads are frequent, but endangered. Tissue culture techniques raise high hopes for the rescue, mass propagation for commercial aims or the conservation of ...

Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]

Ecol Evol
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]

Am J Bot
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.
