The production of biogas as a strategy for biotransforming large volumes of waste into bioenergy is one of the alternatives for reducing greenhouse gases. Metabarcoding analysis aims to understand the role of microbiota from the beginning of the process in the success of biogas production. This study compared microbial diversity and metabolic prediction in a pilot plant producing biogas for vehicular use, utilizing organic sol...
A Proposal for a Hierarchical and Hybrid Methodology for Resource Classification: Integration of Traditional Methods with Risk MapsNARA Subscribed
Mineral resource classification, based on confidence levels associated with tonnages and grades, is essential for public disclosure and for assessing deposit maturity and related risks. Although geometric classification methods are transparent and straightforward, they do not explicitly account for local variations in uncertainty. In contrast, geostatistical approaches focus primarily on the quality of grade estimation. The sc...
Serum Neurofilament Light Levels in Patients with Cerebrotendinous Xanthomatosis: a Pilot StudyNARA Subscribed
Introduction: Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by pathogenic variants in CYP27A1 , leading to cholestanol accumulation and progressive neurological dysfunction. Neurofilament light chain (NfL) is a biomarker of neuroaxonal injury in several hereditary ataxias, but its role in CTX has not been investigated. We aimed to determine whether serum NfL is elevated in CTX and whether i...
A Marseillevirus isolate from the Brazilian wetlandsNARA Subscribed
Marseilleviruses are giant viruses that infect amoebas and have been isolated from various environments. Here, we describe a new strain, isolated from a water sample collected from the Paraguay River in the Brazilian Pantanal, which we have named "Marseillevirus pantanense". Transmission and scanning electron microscopy revealed icosahedral particles approximately 190 nm in diameter. Genomic and phylogenetic analyses show that...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
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...
