This study provides an original assessment of Nauphoeta cinerea residues, an unconventional and largely unexplored biomass, as feedstocks for biocoal production via torrefaction. By addressing a novel insect-derived resource, the work advances waste-to-energy strategies beyond traditional lignocellulosic and agro-industrial residues. Raw cockroach (RC) and defatted cockroach (DC) biomasses were processed under a Central Compos...

The Amazon rainforest is a key component of the Earth system, regulating regional climate, sustaining high biodiversity and carbon stocks. However, it is threatened by climate and land‐use changes. In recent decades, the region has experienced intensified droughts and heatwaves, trends expected to worsen under future warming. In this study, we assess how the timing, length, and spatial distribution of the dry season across the...

Understanding future changes in cumulative water deficit (CWD) is essential for assessing the vulnerability of Amazonian ecosystems to climate change. This study evaluates the performance of CMIP6 models in simulating CWD in the southwestern Amazon from 1985 to 2024 and projects future changes through 2100 under three emission scenarios (SSP1‐2.6, SSP3‐7.0, SSP5‐8.5). CWD was calculated using a fixed evapotranspiration thresho...

Aluminum (Al) contamination in acidic soils severely limits plant growth and development. This study investigated the mechanisms and timing of Al toxicity in Pfaffia glomerata , a medicinal species of growing pharmacological interest. Based on the hypothesis that P. glomerata mitigates Al toxicity through tissue-specific adjustments in redox metabolism, accumulation of protective metabolites, and regulation of genes involved i...

To halt further destruction of the biosphere, most people and societies around the globe need to transform their relationships with nature. The internationally agreed vision under the Convention of Biological Diversity—Living in harmony with nature—is that “By 2050, biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering benefits essential for all...

A new species of Curimatopsis is described from the Rio Nhamundá, Amazon basin in northern Brazil. The new species is distinguished from congeners by the presence of a distinctive concentration of dark pigmentation over the entire lower lobe of the caudal fin, reticulate pattern of body pigmentation, lower jaw longer than and overlapping the anterior portion of the upper jaw, crescent‐shaped posterior nostril and by morphometr...
