Phylogenomics and morphology reveal a new species of Anthurium (Araceae) endemic to the Caatinga Domain in Brazil

TAXON, Volume 75, Issue 2, April 2026.
Abstract The Caatinga is an exclusively Brazilian phytogeographic domain characterized by xerophytic vegetation, high biodiversity, and remarkable levels of endemism. Despite its ecological importance, this region remains understudied, particularly in terms of its floristic diversity.

Hoffmannseggella viridiflora (Orchidaceae, Laeliinae), a New Species from Brazilian Campos Rupestres

Novon: A Journal for Botanical Nomenclature, 2007
ABSTRACT The species of the Brazilian genus Hoffmannseggella H. G. Jones (Orchidaceae, Laeliinae) are under investigation as part of a biosystematic study. A new species, H. viridiflora Verola & Semir, is recognized by differences in morphological characters, such as the spatulate petals and reduced lip, the greenish yellow coloration of the perianth ...

The Blue List Initiative: Guiding Biodiversity Restoration in Brazil's Espinhaço Range

Applied Vegetation Science, Volume 29, Issue 2, April/June 2026.
The campo rupestre is a biodiversity hotspot marked by extreme habitat heterogeneity and high species turnover. Using phytosociological data, floristic clustering and zeta diversity, we show that habitats are floristically non‐interchangeable and propose habitat‐ and substrate‐specific Blue Lists to guide effective, locality‐based ecological ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Biogeographic History and Morphological Trait Influence in the Diversification of the Subtribe Calothecinae (Poaceae)

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim The biodiversity of the Neotropics has been shaped by complex interactions over time with several major geological and climatic events linked to the diversification of lineages. The subtribe Calothecinae (Poaceae) comprises 28 species adapted to open environments, ranging from lowlands to high‐altitude grasslands in America.

Microclimate drives demographic compensation in a narrow endemic tropical species

New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.
