The objective of this study was to evaluate the effects of immunocastration and ractopamine hydrochloride (RAC) supplementation on growth performance and carcass traits of male pigs slaughtered 21 days after the second immunization. Sixty-four pigs (Landrace × Large White, initial body weight 103.05 ± 0.67 kg) were individually tagged and randomly assigned to a 2 × 2 factorial arrangement in a completely randomized design, con...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Exploring Palmaria palmata as a dietary ingredient for European sea bass (Dicentrarchus labrax) juvenilesNARA Subscribed
The red macroalgae Palmaria palmata is rich in protein and bioactive compounds and has been identified as a promising dietary ingredient for aquafeeds, with the potential to partially replace selected plant-based feed components. A digestibility trial and a growth trial were conducted to evaluate the potential of untreated and pretreated P. palmata as feed ingredients for juvenile European seabass ( Dicentrarchus labrax ), wit...
Evolutionary forecast of vineyard yield in a mediterranean climate: A multi-temporal machine learning approach in Cádiz, SpainNARA Subscribed
Purpose Accurate and early prediction of crop yield is essential for agricultural management, economic planning, and market stability, particularly for high-value products such as wine. This study presents a multi-temporal modeling framework to predict grapevine yield (in kilograms) in the province of Cádiz, Spain, a region with a deep-rooted winemaking heritage. Methods Using a 12-year dataset that includes historical harvest...
Codium tomentosum , a marine green macroalga is also produced in integrated multi-trophic aquaculture (IMTA) systems; however, its use in aquafeeds remains unexplored. This study evaluated the potential of C. tomentosum as a feedstuff for European seabass ( Dicentrarchus labrax ) and, for the first time, applied a high-solid-loading alkaline autoclave pre-treatment to enhance its nutritional value. Macroalgal biomass was treat...
Phosphorus is an essential yet limited element that regulates biological productivity and ecological balance within the Earth’s interconnected biogeochemical systems. Its transformations link the lithosphere, hydrosphere, and biosphere; however, the absence of a gaseous phase makes phosphorus one of the least mobile nutrients. Microorganisms play a pivotal role in maintaining its bioavailability through mineralization, solubil...
The effects of dietary inclusion of the macroalgae Codium tomentosum, either untreated or pre-treated with high-solid-loading alkaline hydrolysis, on the oxidative status, intestinal immune responses, and gut microbiota was evaluated in European seabass juveniles. Four diets, a control diet (CTR) and three diets containing 7.5% C. tomentosum, either untreated (COD) or pre-treated for 30 min (COD30) or 60 min (COD60), were form...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Studies of swordfish growth provide essential biological parameters for stock assessment and fisheries management, informing both conventional population models and the evaluation of different management strategies. The present study aims to provide insight into the dynamics of the South Atlantic Ocean stock growth patterns. The sampling is the most complete to date in the literature, with a wide geographical distribution and...
Functional diversity of Brazilian bees: revealing the unique patterns of the NeotropicsNARA Subscribed
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...
The neurotoxic threat of micro- and nanoplastics: evidence from In Vitro and In Vivo modelsNARA Subscribed
Micro- and nanoplastics (MPs/NPs), ubiquitous contaminants in ecosystems and food chains, have emerged as a significant concern due to their potential neurotoxic effects on human health. Here, we conducted a systematic review of the existing literature, which included 26 studies providing evidence from cellular and animal studies on the risks posed by MPs/NPs to the nervous system. In vitro studies reveal that MPs/NPs can disr...
