Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

Optimization of Provitamin A Maize and Iron‐Rich Bean‐Based Composite Flour for Improved Child Nutrition

Food Science &Nutrition, Volume 14, Issue 1, January 2026.
In order to improve child nutrition, the study optimized a composite flour derived from iron‐rich beans and provitamin A maize using Response Surface Methodology. High levels of β‐carotene (1.58 μg/g), iron (6.0 mg/100 g), and sensory acceptability were obtained from the ideal blend (57.9% maize, 17.1% beans, 10% soy, 5% sesame, 5% wheat, and 5 ...

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

Austral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.
