Diversity and Community Structure Underlie Divergence in Thermal Strategies Across Tropical Elevations

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We examined how community diversity and phylogenetic context are associated with plant thermal strategies along a tropical elevational gradient in the Brazilian Atlantic Forest, using Pitcairnia flammea as a focal species. By integrating community surveys, phylogenetic structure, functional traits, and experimental estimates of heat and cold tolerance,

Airborne Plant eDNA Reflects Local Biodiversity: A Multi‐Method Assessment in a Botanical Garden

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Botanical garden sampling site, three air‐sampling approaches, and three sequencing pipelines (amplicon, short‐, and long‐read shotgun). Results demonstrate strong agreement with known plant sources, high complementarity among methods, and substantial contributions of sub‐pollen particles to airborne plant eDNA.

Update on Ouratea cidiana Sastre (Ochnaceae), a microendemic species from the Amazon: enlightening the identity and conservation status

open access: yesNordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Ouratea cidiana (Ochnaceae) is a microendemic shrub species from the Brazilian Amazonia, occurring along the banks of the Trombetas River and restricted to the Cachoeira Porteira region, in western Pará State. Since the original collection nearly forty years ago, no additional records have been made, which is concerning given the continuous decline in ...

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 4, Page 751-775, July 2026.
Using Angiosperms353 and plastid genome skimming, the generic limits of Hyacinthinae were explored. Floral morphology conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define groups similar to those defined by DNA.

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

open access: yesFood Chemistry International, Volume 2, Issue 2, Page 285-294, June 2026.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.
