This study evaluated the effects of providing 3–15 kg of a soluble and biodegradable biopolymer-based enrichment material (blend of biodegradable polymers and natural fibers) to prepartum sows housed in farrowing crates. Fifteen sows were blocked by body weight and backfat thickness and assigned to three treatments: no enrichment material (CONT), 3 kg of enrichment material (BN3), or 15 kg of enrichment material with added nut...
The Asian Green Mussel Perna viridis in the Canal do Itajurú, Brazil: Establishment in a Hypersalinity-Influenced Coastal ChannelNARA Subscribed
The Asian green mussel, Perna viridis , is a globally successful invasive bivalve first recorded in the South Atlantic in 2018. Here, we report and characterize the establishment of P. viridis in the Canal do Itajurú, a coastal channel connecting the hypersaline Araruama Lagoon to the Atlantic Ocean in Rio de Janeiro, Brazil. We assessed its spatial distribution, substrate association, and morphometric variation to evaluate lo...
Melatonin Alleviates Aluminum Toxicity in Pfaffia glomerata by Modulating Tolerance MechanismsNARA Subscribed
Aluminum (Al) toxicity is the main factor limiting agricultural production in acidic soils around the world. In this scenario, melatonin (MET) has emerged as a promising approach to alleviate Al toxicity. Thus, we investigated morphophysiological responses of Pfaffia glomerata (Spreng.) Pedersen, a medicinal plant, to Al toxicity and MET application. Plants were grown in vitro for 40 days in MS medium (control) supplemented wi...
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...
The COVID-19 pandemic triggered unparalleled political, economic, and social ramifications, exacerbating global food insecurity (FI). To understand the overall impact of the pandemic and how different socio-economic groups were affected, we assessed prevalence and severity of FI in a sample of 18,997 households across seven countries in South America. We employed the Food Insecurity Experience Scale developed by the FAO. Our r...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Evaluation of the convection-permitting regional climate model CNRM-AROME41t1 over Northwestern EuropeNARA Subscribed
Since a decade, convection-permitting regional climate models (CPRCM) have emerged showing promising results, especially in improving the simulation of precipitation extremes. In this article, the CPRCM CNRM-AROME developed at the Centre National de Recherches Météorologiques (CNRM) since a few years is described and evaluated using a 2.5-km 19-year long hindcast simulation over a large northwestern European domain using diffe...
Mitigation of nitrous oxide emissions in grazing systems through nitrification inhibitors: a meta-analysisNARA Subscribed
Grasslands are the largest contributor of nitrous oxide (N 2 O) emissions in the agriculture sector due to livestock excreta and nitrogen fertilizers applied to the soil. Nitrification inhibitors (NIs) added to N input have reduced N 2 O emissions, but can show a range of efficiencies depending on climate, soil, and management conditions. A meta-analysis study was conducted to investigate the factors that influence the efficie...
