Diversity and distribution of the bryophyte flora in montane forests in the Chapada Diamantina region of Brazil

open access: yesActa Botânica Brasílica, 2013
Bryophytes constitute an important component of tropical rain forests, which provide microhabitats favorable for their establishment. Bryophytes are also quite responsive to changes in microclimate, which makes them good bioindicators.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

A new species from an inselberg in the Brazilian Atlantic forest: Stachytarpheta forzzae (Verbenaceae), supported by morphological, palynological and anatomical evidence

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
We describe Stachytarpheta forzzae, a new species from an inselberg located in the municipality of Guaratinga, state of Bahia, within the Brazilian Atlantic forest. Morphologically, it resembles S. sprucei, the only other species of the genus known to inhabit inselbergs.

Beyond the Highlands: Climate Drives Evolutionary Connections Between Ancient Neotropical Mountains and Lowland Biomes

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim The assembly of montane plant communities through time is underlain by historical and abiotic factors. However, the extent of evolutionary connectivity between ancient highland ecosystems and surrounding lowlands remains unclear. Here, we investigate the evolutionary connections between the campos rupestres, a hyperdiverse and fragmented ...
