This study evaluated the anti-inflammatory and antioxidant effects of a methanolic extract of Byrsonima intermedia leaves (EBi) in a rat model of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. Male Wistar rats received intracolonic TNBS for lesion induction and relapse, followed by oral treatment with EBi for seven days. EBi markedly reduced the severity of colonic injury, as demonstrated by a 63% decrease in macr...
Homogenization and functional simplification of zooplankton in reservoirs connected by water transferNARA Subscribed
Water transfer projects between river basins have been globally adopted as strategies to mitigate water scarcity, especially in semi-arid regions. Although their socioeconomic benefits are widely recognized, the ecological effects of these interventions on aquatic ecosystems remain poorly understood. This study investigated how artificial connectivity between reservoirs influences the taxonomic and functional structure of zoop...
Geoengineering techniques have been applied to control phosphorus and cyanobacteria, showing promising outcomes for the restoration of eutrophic aquatic ecosystems worldwide. However, the effects of the materials used in these techniques on non-target organisms, like zooplankton communities, are not well understood. This study evaluated the impacts of the materials used in the Floc and Sink geoengineering technique—specificall...
Modeling Future Climate Impacts on Brazil’s Operational Wind and Solar Energy CapacityNARA Subscribed
Over the past decade, the Brazilian electricity sector has undergone a profound transformation, driven by the large-scale deployment of wind and solar photovoltaic power plants, a trend that is expected to continue in the years ahead. Although the transition to these variable renewable energy resources helps to reduce greenhouse gas emissions and mitigate the climate crisis, they are vulnerable to the very climate changes they...
Mo-CBP3-PepIII Changes the Proteomic Profile of Gastric Cancer Cells, Induces Membrane Pore Formation, and ROS OveraccumulationNARA Subscribed
Background Synthetic peptides have gained prominence due to their potential structural alterations and selective toxicity. In this context, Mo -CBP 3 -PepIII, derived from Moringa oleifera , was developed to increase selectivity against tumor cells. This study evaluated its activity in AGS cells and demonstrated low toxicity in non-tumor cells, MNP-01. Its mechanism of action was investigated using membrane integrity analyses,...
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...
The Amphilinidea represents a peculiar and little‐known order of monozoic cestodes. In a study on Crenicichla cincta collected from the Gama River in the Brazilian State of Amazonas, some amphilinideans were found in the small intestine of the fish. The morphological and genetic characterization of these parasites revealed that they represent a new genus and species, which was named Pochelia juruaensis gen. et sp. n . The new...
NEOTROPICAL FRESHWATER FISHES : A dataset of occurrence and abundance of freshwater fishes in the NeotropicsNARA Subscribed
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distri...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...
