The pygmy ( Kogia breviceps ) and dwarf ( Kogia sima ) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp. occurrence along the Brazilian coast, spanning both the Equatorial Atlantic Ocean (EAO) and Southw...
Photocatalytic caffeine degradation and toxicity reduction using reduced graphene oxide-modified zinc tellurideNARA Subscribed
The occurrence of emerging pollutants in aquatic matrices has raised environmental concern because of their persistence and potential toxicity. This study assessed caffeine degradation and toxicity reduction using zinc telluride functionalized with reduced graphene oxide as heterogeneous photocatalyst. The catalysts were synthesized by the wet impregnation method with excess solvent, and characterized by physicochemical and op...
Calibration and validation of the safer evapotranspiration model using Landsat 8 and eddy covariance data in vineyardsNARA Subscribed
Accurate estimates of actual evapotranspiration (ET a ) are essential for irrigation management in vineyards. This study locally calibrated and validated the Simple Algorithm for Evapotranspiration Retrieving (SAFER) model for California vineyard systems using Landsat 8 imagery and multi-year eddy covariance (EC) measurements collected between 2013 and 2016 in the Central Valley of California. Two calibration approaches were i...
On-Demand Hospital Manufacturing of Baclofen Lozenges Using Pharmaceutical 3D PrintingNARA Subscribed
Purpose Dysphagia in neurological patients complicates oral drug administration. Manual preparation of lozenges/troches lacks precision and scalability. This study investigates the feasibility of implementing a pharmaceutical 3D printer in a hospital pharmacy for the automated production of personalized baclofen troches. Methods Baclofen troches were manufactured in a hospital pharmacy setting, both manually and via pharmaceut...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Digoxin Derivative BD-8 Attenuates Oxidative Stress and Neuroinflammation in an LPS-Induced Experimental ModelNARA Subscribed
Chronic neuroinflammation contributes to neuronal damage through oxidative stress and inflammatory mediators, highlighting the need for novel therapeutic strategies. This study evaluated the cytotoxicity and neuroprotective effects of BD-8, a digoxin-derived cardiosteroid, in vitro and in vivo. BD-8 showed lower cytotoxicity than digoxin, with CC₅₀ values of 7.4 µM in SH-SY5Y cells and 8.5 µM in BV-2 cells, while digoxin prese...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Seasonal variations in biofiltration efficiency of fish farm effluents using Ulva spp.NARA Subscribed
Intensive aquaculture generates nutrient-rich effluents that contribute to eutrophication if discharged untreated. Seaweed cultivation offers a sustainable approach to mitigate this impact while producing valuable biomass. This study evaluated the seasonal biofiltration efficiency and biomass production of Ulva spp. under simulated flatfish aquaculture effluent conditions using two experimental designs: parallel tanks and seri...
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...
