Sugarcane nutrition under organomineral fertilizer, phosphate‐solubilizing bacteria, and reduced phosphate doses

Annals of Applied Biology, EarlyView.
Sugarcane phosphorus (P) availability is limited in tropical soils, requiring strategies to improve fertilizer efficiency. This study evaluated Bacillus velezensis UFV 3918 (Bv) in combination with an organomineral fertilizer (OF) at reduced monoammonium phosphate (MAP) doses. It showed that Bv + OF + 1/3 MAP achieved soil and plant P levels comparable

Threats to and management of Natura 2000 protected areas relative to agricultural practices

Conservation Biology, EarlyView.
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...
