Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.

Understory frog communities recover quickly during tropical forest regeneration

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Millions of hectares of tropical forest have been lost to agriculture, posing a major threat to biodiversity. However, where agricultural activities do not cause irreversible damage, forests can regenerate after abandonment, forming secondary forests that are increasingly important for conserving forest species.

Selective Lipoprotein Removal Enables High‐Purity EV Isolation from Plasma via Aptamer‐Based Mesh Filtration

Small, Volume 22, Issue 24, 27 April 2026.
A novel affinity‐based mesh filtration system, ApoFilter, enables selective removal of plasma lipoproteins via sequential aptamer‐functionalized layers targeting ApoA1 and ApoB100. While EVs pass through unimpeded, (V)LDL and HDL are rapidly depleted.

A connecter-like factor, CacA, links RssB/RpoS and the CpxR/CpxA two-component system in Salmonella

BMC Microbiology, 2012
Background Bacteria integrate numerous environmental stimuli when generating cellular responses. Increasing numbers of examples describe how one two-component system (TCS) responds to signals detected by the sensor of another TCS.

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Monitoramento participativo de caça de subsistência da Reserva Extrativista Tapajós-Arapiuns (PA): caminhos para uma participação social efetiva

Biodiversidade Brasileira, 2018
A atividade de caça é uma das principais causas da perda de biodiversidade. Medidas de conservação que consigam alinhar a caça à preservação de espécies ao desenvolvimento local são fundamentais.
