The Ferruginous Rupestrian Grassland is a highly biodiverse ecosystem that harbors endemic species vulnerable to anthropogenic activities and climate change, such as Sinningia rupicola , classified as endangered. In vitro cultivation enables large-scale seedling production with high physiological quality. Among the factors influencing the success of the technique, spectral quality stands out, acting on photosynthesis and morph...
Nutrient washing to amend nitrite accumulation during hydrocarbon remediation of Antarctic soilNARA Subscribed
Nitrogen-based fertilizers are frequently employed in bioremediation to stimulate microbial degradation of hydrocarbon contaminants. At Casey Station, in eastern Antarctica, a urea-based fertilizer was applied to seven engineered biopiles to remediate soils impacted by historic diesel spills. While this treatment enhanced hydrocarbon degradation, it also altered soil chemistry, resulting in elevated concentrations of ammonia a...
Lithology Classification Based on Well Log Data: A Benchmark for Machine Learning ModelsNARA Subscribed
Lithology classification based on well log data has attracted the attention of geologists, as the extraction of rock samples from the wellbore is a costly process. Although some machine learning techniques have recently been applied to the problem, the existing studies are not standardized in terms of data processing and evaluation protocols. This paper aims to bridge this gap by providing common ground for the comparison of p...
The ecological impact of cattle grazing on Brazilian savannas is poorly known. This study aimed to evaluate vegetation structure, diversity, and fuel load in savannas under rotational grazing. We studied three adjacent, fire-excluded savanna fragments in Central Brazil: one subjected to rotational grazing, one excluded from grazing for 2.5 years, and one ungrazed. For vegetation sampling, we used the line-point intercept metho...
Wildlife monitoring is essential for guiding biodiversity conservation strategies, particularly in fragmented ecosystems under intense anthropogenic pressure. While noninvasive methods, such as camera traps, are widely used for terrestrial species, their application in other forest strata is underexplored despite its potential for studying elusive and nocturnal arboreal mammals. We aim to evaluate whether arboreal camera trapp...
Expanding beyond the exome: identifying pediatric patients best suited for genome sequencingNARA Subscribed
Objective This study aimed to compare the diagnostic yield of genome sequencing (GS) versus exome sequencing (ES) in a pediatric population, with a focus on determining whether GS offers a significant advantage over ES in identifying genetic variants. Methods A retrospective analysis of prospectively allocated pediatric patients was performed on 297 pediatric patients who underwent next-generation sequencing. Of these, 59.6% (...
