Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, Volume 2026, Issue 3, March 2026.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Boundaries Within the Paepalanthus chiquitensis Species Complex (Eriocaulaceae)

open access: yesFeddes Repertorium, Volume 137, Issue 1, March 2026.
ABSTRACT Four morphotypes with associated names are presented toward a more reliable circumscription of Paepalanthus chiquitensis. Morphotype I, associated with the names P. chiquitensis, P. speciosus var. bolivianus, and P. amoenus var. bolivianus, is restricted to savannas of Bolivia and western Brazil.

Integrated Anatomical, Chemical, Biological and Computational Studies Approach of Myrcia sylvatica (G. Mey) DC. A Multifaceted Insight Into a Promising Amazonian Species

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 2, Page 270-293, March 2026.
This study presents an integrated anatomical, chemical, biological, and computational analysis of Myrcia sylvatica, revealing key bioactive compounds with antioxidant and toxicological potential, and identifying spathulenol and globulol as promising acetylcholinesterase inhibitors with favourable pharmacokinetic properties. ABSTRACT Myrcia sylvatica (G.
