Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3169-3186, November 2026.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Flashy Neighbours: Psilocladus mantilleri Zeballos, Nunes, Silveira & Rosa, sp. nov., the First Termitariophile Firefly Larva (Coleoptera: Lampyridae)

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Fireflies are semelparous beetles whose immature stages are largely unknown. The comparatively few larvae known span diverse ecological niches, such as ground‐dwellers, aquatic (freshwater or marine), semi‐aquatic and arboreal. Psilocladus costae Vaz, Silveira & Rosa, 2020—a bromeliad dweller—is the only species of its genus and subfamily in ...

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

open access: yesNordic Journal of Botany, Volume 2026, Issue 10, October 2026.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Guild‐Based Metacommunity Internal Structure: Insights From Waterbird Assemblages in a Dynamic Estuarine System

open access: yesJournal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Understanding how ecological processes shape species assemblages in dynamic environments is central to community ecology. Estuarine waterbirds are a compelling system for metacommunity analysis because their high mobility, functional diversity and sensitivity to environmental variation make them well suited to examine how assembly is ...

CYCLOP Revegoca: The First Documented Cyclone Formed From Locally Originating Potential Intensity Over the Southwestern South Atlantic

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract On 9 December 2025, an atypical synoptic cyclone developed near the borders of Paraguay, Argentina, and southern Brazil, triggering severe weather across south‐southeastern Brazil. Unlike typical South Atlantic extratropical cyclones, which intensify near the coast, this system originated inland and underwent explosive cyclogenesis without a ...

QUALIDADE FISIOLÓGICA DE SEMENTES DE Araucaria angustifolia (Bertol.) Kuntze SUBMETIDAS A DIFERENTES CONDIÇÕES DE ARMAZENAMENTO E A ESCARIFICAÇÃO [PDF]

open access: yesCiência Florestal, 2006
As sementes de Araucaria angustifolia (Bertol.) Kuntze (pinheiro-do-Paraná) são recalcitrantes e, portanto, perdem rapidamente a viabilidade após a colheita, o que dificulta a sua utilização na produção de mudas. Este trabalho teve como objetivos avaliar
