Ecology 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 ...

Boundaries Within the Paepalanthus chiquitensis Species Complex (Eriocaulaceae)
Feddes 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.

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.Stemodia diplohyptoides M.M.Sosa & Dematt. and S. lobelioides Lehm. (Gratioleae, Plantaginaceae) are reported for the first time in Paraguay, found in Alto Paraná and Presidente Hayes departments, respectively. These new records extend the known geographical range of both species, representing the northern records to date, S.

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems
Oikos, Volume 2026, Issue 3, March 2026.Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

Influence of Fertilization on the Phytoremediation of Lead‐Contaminated Soils Using Tropical Grasses
Environmental Quality Management, Volume 35, Issue 3, Spring 2026.ABSTRACT Lead is an element intensively used by human activities, representing serious risks to food security due to soil contamination, making it essential to implement control strategies to mitigate its harmful effects. The objective of this study was to evaluate the influence of soil fertilization on the growth and lead accumulation of grasses used ...

Molecular and Serological Detection of Coxiella burnetii in Small Ruminants in Northeastern Brazil
Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.• Serology indicates that one‐third of the sheep and goats had previously been infected with Coxiella burnetii. • qPCR analysis revealed the ongoing presence of C. burnetii in all evaluated flocks, each with a previous history of reproductive disorders. • These results indicate the need for preventive measures and control of C.

Austral Ecology, Volume 51, Issue 3, March 2026.ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...
