Different Grazing Frequencies Modify the Structure, Production, and Nutritional Value of ‘Zuri’ Guineagrass in the Brazilian Cerrado

open access: yesGrass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT The increasing climate variability in tropical regions demands management goals that allow for shorter rest periods without compromising pasture persistence. The objective of this study was to evaluate the effects of four pre‐grazing light interception (LI) levels on the structural, productive, and nutritional responses of ‘Zuri’ guinea grass ...

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

open access: yesGrassland Science, Volume 72, Issue 2, Page 73-81, April 2026.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...

Optimization of passive acoustic bird surveys: a global assessment of BirdNET settings

open access: yesIbis, Volume 168, Issue 2, Page 785-798, April 2026.
BirdNET is a popular machine learning tool for automated recognition of bird sounds. However, evidence on how to optimize its settings for accurate bird monitoring remains limited. Here, we evaluate how BirdNET settings influence model performance in identifying bird vocalizations and characterizing bird communities, using 4224 1‐min recordings from 67

The Biogeography of ENSO‐Induced Climate Variability, Deforestation Trends and Fire‐Induced Forest Loss in the Neotropics

open access: yesJournal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim To identify Neotropical ecoregions experiencing compound environmental exposure to El Niño/La Niña‐driven climate variability, deforestation trends and fire‐induced forest loss. Location Neotropical realm. Methods We quantified historical exposure to ENSO‐related climate variability by correlating the Oceanic Niño Index with four ...

Adenosine A2A Receptors Control the Mis‐Localization of Aquaporin‐4 in Rats Subject to Repeated Restraint Stress

open access: yesJournal of Neurochemistry, Volume 170, Issue 4, April 2026.
Restraint stress triggers anxiety, along with a loss of polarization and coverage of aquaporin‐4 (AQP4) in astrocytes of the frontal cortex; these effects are attenuated by blockade of adenosine A2A receptors. ABSTRACT Repeated stress triggers anxiety accompanied by a deregulation of cortical glucocorticoid receptors, which is relieved by blocking ...
