Colorectal cancer (CRC) is a multifactorial disease strongly influenced by genetic and environmental factors, as well as by immune and metabolic disorders such as obesity and gut dysbiosis. Recent evidence highlights the interplay between the endocannabinoidome (eCBome) and the gut microbiota as a central regulatory axis of intestinal homeostasis, metabolism, and immune responses. Although no studies have directly investigated...

Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...

While bats are known to harbor various viruses and bacteria, their role as hosts for hemoparasites has not been extensively studied. This research investigated the presence of ectoparasites and vector-borne pathogens—including Anaplasmataceae agents, hemoplasmas, apicomplexans, and kinetoplastids—in 74 Phyllostomidae bats sampled from an urban forest fragment in southeastern Brazil. Overall, 31.1% of the bats were infested wit...

Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...

We used acoustic telemetry to investigate the nursery habitat use of 33 juvenile meagre Argyrosomus regius (mean size = 581 ± 105.1 mm), recording more than 60,000 detections in the Tagus estuary, located in the North-Eastern Atlantic. All individuals used the nursery area from spring to autumn, and a small number (22.2%) remained in the Tagus estuary during winter. Daily movements averaged 6.2 ± 1.9 km, with maximum daily dis...

Plants have developed adaptive strategies to combat dehydration, including forming associations with microbes, which help plants cope with drought by altering hormone levels, enhancing antioxidants, or improving water uptake. Selaginella species, the resurrection plants, can endure desiccation and revive with rehydration. Here, we investigated the bacteriome of leaves and roots of S. convoluta and S. sellowii inhabiting rocky...

Summary Two new species of Digitaria are described from two locations in western Tanzania, including the Uzondo plateau, following collecting trips by Kaj Vollesen and colleagues, Digitaria laciniata and D. setarioides . Line drawings accompany the descriptions and scanning electron micrographs show spikelet and trichome morphology. Digitaria parodii is recorded from Tanzania for the first time. All three species represent asp...

Along more than 2,500 km of tropical coastline north of Rio de Janeiro, the invasive coral Tubastraea spp. has primarily been observed on shipwrecks and oil platforms located on the outer continental shelf or slope. An exception is Baía de Todos os Santos (BTS), a large estuary near 13°S, where Tubastraea spp . has been repeatedly documented since its first occurrence in 2012. These reports have raised concerns about BTS poten...

Air pollution is a critical environmental issue influenced by both natural and anthropogenic sources. We hypothesized that PM 2.5 chemical composition varies spatially due to local anthropogenic sources, soil resuspension, and biomass burning. This study analyzed particulate matter (PM 2.5 ) concentrations and chemical composition (black carbon (BC), elements, and ions) in three locations in Rio de Janeiro state: Gávea (urban...

Wastewater treatment remains a challenging issue in developing countries, particularly due to the difficulty in controlling nitrogenous compounds release. Anaerobic reactors are widely used and effective in removing organic matter, but they are usually insufficient to meet nitrogen discharge criteria. The recirculation of nitrified effluent has become a viable alternative to promote denitrification without major structural cha...
