Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

Journal of Applied Entomology, Volume 150, Issue 8, Page 1017-1024, September 2026.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

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 ...

Premature pollen development hinders autonomous self-pollination and promotes insect pollination in soybean (Glycine max L.)

Scientific Reports
Flower traits (e.g., self-compatibility) determine pollinator dependence, and thereby seed production and mating. But crop research often overlooks how specific flower traits influence pollination quantity and quality and, consequently, yield.

Floral resource‐mediated multilayer networks: structure and pollinators' roles

Oikos, Volume 2026, Issue 8, August 2026.
Resource availability shapes interactions among free‐living species, particularly in plant–pollinator mutualisms, where the composition of floral resource types influences pollinator foraging. Bees, known for utilizing a broad array of floral resources, play a crucial role in these dynamics. However, how the structure of interaction networks vary among
