Vitex oreadica and V. umbellata (Lamiaceae): two new species from Cerrado and Atlantic forest of Brazil

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

TAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, Volume 40, Issue 8, Page 2379-2391, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Identification of a Benzenesulfonylpiperazine Derivative With In Vivo Efficacy Against Visceral Leishmaniasis

Chemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
This work highlights the satisfactory pharmacokinetic profile of two benzenesulfonylpiperazine lead candidates, followed by in vivo assessment in a murine model of visceral leishmaniasis. This assessment identified compound 2 as moderately active at a lower dose, but its efficacy increased at higher doses, though with concerns regarding safety.

Carbon Stocks in Sugarcane Biomass and Their Implications on Land Use Change CO2 Balance in Brazil

GCB Bioenergy, Volume 18, Issue 8, August 2026.
This paper develops a regionalized carbon stock factor for sugarcane biomass in Brazil, showing that sugarcane cultivation can lead to net carbon removal in most municipalities. The findings improve greenhouse gas inventories and support bioenergy policies by providing more accurate, spatially resolved estimates for land use change emissions.
