Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Contrastive ecoacoustic indices: Large‐scale global soundscape characterization with contrastive inference

Methods in Ecology and Evolution, EarlyView.
Abstract Ecoacoustics mainly aims at monitoring soundscapes by means of non‐invasive protocols. Despite the widespread adoption of machine and deep learning techniques, existing ecoacoustic models predominantly rely on supervised learning and, consequently, face two primary limitations: (1) the necessity of annotated data; and (2) the restriction to ...

Influência da aplicação de água na uniformidade da umidade no perfil do solo

Acta Scientiarum. Agronomy, 2008
A uniformidade de aplicação de água na superfície do solo tem sido usada para caracterizar a qualidade de irrigações. Uma vez que a planta retira água do volume de solo no qual o seu sistema radicular se encontra, pode-se supor que a uniformidade de ...

Infectious bacterial keratitis management in a Swedish region: Risk factors, treatment and time‐to‐resolution

Acta Ophthalmologica, EarlyView.
Abstract Purpose To report treatment patterns, time‐to‐resolution (TTR) and aetiologies of bacterial keratitis (BK) infections treated in a specialized hospital‐based cornea clinic in Sweden. Methods Retrospective study based on electronic health records screened during the period 2010–2019. The study included only culture‐confirmed cases of BK.

Evaluation of reference evapotranspiration by Penman-Monteith using minimum climatic data in the backcountry of Ceará = Avaliação da evapotranspiração de referência por Penman-Monteith usando dados climáticos mínimos no sertão do Ceará

Agro@mbiente On-line, 2013
In areas of semiarid climate, water resources are limited and seriously threatened by excessive exploitation. This study’s objective is to evaluate the performance of the method FAO 56 Penman-Monteith (PM-FAO 56) to estimate the reference ...

16S/18S metabarcoding versus culture for aetiological assessment in infectious keratitis: A prospective paired‐sample study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Infectious keratitis (IK) is a vision‐threatening condition with diverse microbial aetiologies, yet conventional culture‐based diagnostics often have limited sensitivity. We investigated whether 16S/18S rRNA amplicon‐based next‐generation sequencing (NGS) can enhance aetiological assessment when used alongside standard microbiological ...

Key agroecosystems for the conservation of amphibians and reptiles in Europe

Conservation Biology, EarlyView.
Abstract Agricultural expansion and intensification are driving amphibian and reptile declines worldwide. However, sustainably managed agroecosystems can support a high diversity of herpetofauna, which play a key role in pest control, reducing crop damage.
