Molecular investigation of the phylogenetic placement of Kartalinia and a revision of Bituminaria (Fabaceae: Psoraleeae)

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Kartalinia was described to accommodate a single, obscure species, Psoralea acaulis, based on its unique morphology and karyology. No concerted molecular phylogenetic studies were available for this species at the time, and therefore its phylogenetic position was uncertain.

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1223-1237, July 2026.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

An Announced Extinction: The Impacts of Mining on the Persistence of Arthrocereus glaziovii, a Microendemic Species of Campos Rupestres

open access: yesConservation
The mountaintops of eastern Brazil harbor the highest rates of plant endemism in South America. However, local biodiversity faces constant threats due to habitat loss and mining activities.

Effects of Time‐Since‐Fire on Ant Interactions With Nectar Resources in a Semi‐Arid Landscape

open access: yesAustral Ecology, Volume 51, Issue 7, July 2026.
ABSTRACT Semi‐arid ecosystems are shaped by frequent wildfires, making the management of landscape disturbances a major conservation challenge in this region. Ant–plant nectar interactions, driven by mutualisms, contribute to ecosystem functioning and biodiversity, with interaction networks a poorly understood aspect of ecosystem recovery from ...

Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

Species Composition of Termites (Isoptera) in Different Cerrado Vegetation Physiognomies

open access: yesSociobiology, 2013
Little is known about the termite fauna of the different vegetation physiognomies in the Cerrado biome. It is suggested that the species compositions in grassland and savanna areas are closely related to each other, and quite distinct from those of ...

Revisiting the typification of Lippia riedeliana (Verbenaceae)

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract The present study revisits the previously selected lectotype for Lippia riedeliana, which was designated in a proposal to reject this name. According to our reinterpretation, this typification was based on non‐original material and, therefore, must be superseded. The holotype is at LE, and this specimen must be cited accordingly.

Growing straight versus growing decumbent: soil quality and allometry in Syagrus glaucescens Becc. (Arecaceae), an endemic and threatened palm of the Espinhaço Mountains, Brazil

open access: yesActa Botânica Brasílica, 2015
Syagrus glaucescens is an endemic palm found in the rupestrian grasslands of the Espinhaço Mountains in southeastern Brazil. It is highly associated with quartzitic soils and exhibits strong intra-specific morphological variation in the different areas ...
