Global Hydroclimatic Controls on Multithread River Dynamics
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Molecular Ecology, Volume 35, Issue 7, April 2026.ABSTRACT Host species have evolved different strategies for dealing with parasites. ‘Vulnerable’ hosts, which suffer reduced fitness from parasites, are under selection to evolve defences. ‘Tolerant’ hosts, by contrast, avoid reductions in fitness by mitigating parasite damage.

Hemispheric Synoptic Patterns Control Rainfall and Long‐Range Aerosol Transport in the Amazon
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The transatlantic transport of dust and smoke aerosols from Africa to South America is a large‐scale, year‐round process that affects atmospheric and nutrient cycling in the Amazon rainforest. We analyze daily variations in black carbon at the Amazon Tall Tower Observatory (ATTO) to investigate how Atlantic synoptic‐scale meteorology ...

Polymer Composites, Volume 47, Issue 5, Page 4793-4803, 10 March 2026.Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,
