Decoupling of Taxonomic and Functional Recovery in a Multi‐Decadal Mixed Araucaria Forest Chronosequence

open access: yesAustral Ecology, Volume 51, Issue 8, August 2026.
ABSTRACT Understanding how different biodiversity dimensions recover following disturbance is critical for interpreting forest successional trajectories. We examined this question in a protected remnant of Araucaria Mixed Forest (AMF) in subtropical southern Brazil, a frost‐prone montane system with multiple anthropogenic disturbance legacies.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Stylosanthes cv. Campo Grande response to Bradyrhizobium inoculation in an Amazon Cerrado Oxisol

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Species of the genus Stylosanthes show great potential for use in mixed pastures and as green manure due to their symbiotic potential in symbiosis with diazotrophic bacteria, particularly Bradyrhizobium. These herbaceous legumes can improve pasture quality and contribute to sustainability.

Matchmaking: a meta‐analysis of plant growth‐promoting microbial partnerships driving tree seedling performance in the Atlantic Forest biome

open access: yesRestoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction The Brazilian Atlantic Forest (BAF) is a biodiversity hotspot, and inoculating native seedlings with plant growth‐promoting microorganisms (PGPMs) may enhance seedling vigor for forest restoration. Objectives We performed a meta‐analysis to evaluate the effects of PGPMs on BAF seedlings and identify strategies to optimize ...

Recruitment of Native Pollinators and Dispersers by Lonicera japonica May Facilitate Its Invasion and Its Potential Threat to Local Biodiversity

open access: yesAustral Ecology, Volume 51, Issue 4, April 2026.
ABSTRACT Lonicera japonica is a plant native to Asia that has been widely used in landscaping as an ornamental plant, but has escaped cultivation and become invasive in several countries. This study examined the reproductive phenology, pollinator attraction, and potential dispersal mechanisms of L.

Pollen dispersal and gene flow by pollen in Araucaria angustifolia

open access: yesAustralian Journal of Botany, 2003
Araucaria angustifolia (Bert.) O.Ktze. is an economically important tree in southern Brazil. Indiscriminate exploitation is threatening this species with extinction. Conservation programs are urgently needed to save the remaining forest, and such programs must be guided by biological studies that genetically characterise the remaining populations ...

Anatomical and Physicochemical Characterization of the Araucaria angustifolia Seed Coat [PDF]

open access: yesFloresta e Ambiente, 2019
ABSTRACT Seed coat plays an important role in the embryo protection and seed germination. This study aimed to characterize the anatomical structure, histochemical and physicochemical aspects of the seed coat of Araucaria angustifolia Kuntze. Light and scanning microscopy usual procedures, and histochemical tests were used to describe and characterize ...
