Background Chronic inflammatory pain is associated with persistent sensory and immune dysregulation. We evaluated the therapeutic efficacy of two cannabinoids formulations—Cannabigerol (CBG) and Standardized Full-Spectrum Cannabis Extract (FULL) in a preclinical model of acute and Chronic inflammatory pain and examined their effects on peripheral and central inflammatory mediators. Methods Cannabinoid analgesic effects were as...

The American manatee ( Trichechus manatus ) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater. We applied MaxEnt modeling to presence‐only data (sightings and filtered telemetry records) to p...

Main conclusion The biological control of phytophagous mites mediated by predatory mites promotes the maintenance of plant physiology by mitigating damage and preserving key traits related to photosynthesis and development. Abstract The immune system of plants, upon perceiving the presence of phytophagous mites, triggers signals mediated by reactive oxygen species (ROS). Under intense infestations, these redox signals can trig...

Introduction This study investigates the size composition of Brachyplatystoma vaillantii specimens caught by the Amazon industrial fleet, identifying spatiotemporal patterns and assessing the vulnerability of juveniles to fishing. Methods The research was conducted at the Amazon River mouth, using data collected by onboard scientific observers between 2008 and 2011, including catch records and length sampling of goliath catfis...

Temperature and light intensity are among the most influential environmental factors modulating cyanobacterial physiology, yet their interactive effects on metabolite accumulation remain understudied in several genera with biotechnological potential. In this study, the influence of temperature (12, 20 and 28 °C) and light intensity (60, 120 and 180 µmol photons m −2 s −1 ) on the growth, pigment profile, and lipid composition...

Sternochetus mangiferae is a pest of mangoes, occurring worldwide in regions where mangoes are cultivated. In Brazil, this insect was first detected in 2014 in Seropédica, Rio de Janeiro, and since then, various measures and studies have been conducted to contain, monitor and potentially eradicate it. Semiochemicals may provide feasible targets to develop sensitive detection and monitoring tools. Therefore, this study aimed to...

Non‐native species introductions have caused biodiversity loss worldwide, yet it is unclear how temporal diversity patterns vary across native and non‐native communities, and what mechanisms control their respective dynamics and assembly. Using a unique 12‐year time series dataset of arthropods sampled in forest fragments on Terceira Island, we observed no systematic species losses but steady temporal β‐diversity (Sørensen dis...

Bees are essential for ecosystem functioning, pollinating many wild and crop plant species. Predicting which species are most vulnerable to global changes, and how their loss may impact ecosystems and human well-being, is critical. Comprehensive information on bee response and effect traits is fundamental to these assessments. However, the Raunkiærian shortfall—insufficient trait data—remains significant for bees, particularly...

Aim Oceanic islands are known for being home to drastically different communities compared to the mainland, as their isolation and limited area significantly favour clades able to travel long distances over water. On spiders, this happens mainly, although not exclusively, through ballooning whose propensity is unevenly distributed across species and requires specific conditions, possibly influencing their microhabitat distribu...
