The Missing Branches of the Bee Tree of Life: Addressing Global Darwinian Shortfalls and Their DriversNARA Subscribed
Aim Estimate the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) of bees worldwide, as well as identify their drivers. Location Global. Taxon Bees (Hymenoptera, Anthophila). Methods We built phylogenies for over 12,000 bee species, combining the most comprehensive phylogeny and an algorithm with random solutions to insert missing lineages. The Darwinian shortfall was quantified as the Phyloge...
El Niño Reduces Beta Diversity of Fish Assemblages Across a Large Subtropical Coastal LagoonNARA Subscribed
The El Niño –Southern Oscillation (ENSO) profoundly alters climatological and hydrological conditions, reshaping environmental gradients and ecological dynamics in riverine, estuarine, and coastal ecosystems. We hypothesized that El Niño events would promote homogenization of fish assemblages and reduce β-diversity, whereas La Niña conditions would enhance habitat differentiation and increase β-diversity. To test this hypothes...
Agroforestry systems as habitat aggregators: a spatiotemporal analysis of the Brazilian subtropical Atlantic forestNARA Subscribed
Agricultural expansion, especially in the Neotropics, has been a major driver of habitat and ecosystem loss through the conversion of native vegetation into croplands and pastures. In southern Brazil, large areas of Atlantic Forest have been lost for this purpose. Current estimates suggest that only 7.5% of the original Atlantic Forest remains. In contrast, alternative agricultural approaches, particularly Agroforestry Systems...
Nursery habitat use of juvenile meagre (Argyrosomus regius): findings from acoustic telemetry in the Tagus estuaryNARA Subscribed
We used acoustic telemetry to investigate the nursery habitat use of 33 juvenile meagre Argyrosomus regius (mean size = 581 ± 105.1 mm), recording more than 60,000 detections in the Tagus estuary, located in the North-Eastern Atlantic. All individuals used the nursery area from spring to autumn, and a small number (22.2%) remained in the Tagus estuary during winter. Daily movements averaged 6.2 ± 1.9 km, with maximum daily dis...
The use of herbicides in modern agriculture has been the subject of ongoing debate due to their negative impacts on the environment and human health. The aim of this study was to assess the bacterial, physicochemical and genotoxicity parameters of three soil samples of public farming settlements in Petrolândia, Brazil. The bacterial resistance patterns were examined after soil exposures to a known concentration of glyphosate (...
What percentage of neuromuscular strength reduction in older adults determines the decline in walking speed?NARA Subscribed
Background/Objective Although different neuromuscular strength (NS) cutoff points have been proposed to identify low walking speed (WS) in older adults, the extent to which NS changes predict long-term WS decline remains unclear. This study aimed to determine the percentage of NS change associated with WS decline in older adults. Methods A longitudinal analysis was conducted using data from 4,541 participants aged ≥ 60 years i...
Removal of Bisphenol A, Bisphenol S, and Estrogenic Activity from Real Wastewater Using a Multi-stage IFAS SystemNARA Subscribed
This study evaluated the removal of bisphenol A (BPA), bisphenol S (BPS), and estrogenic activity from real municipal wastewater using a pilot-scale multi-stage integrated fixed-film activated sludge (MS-IFAS) system. The configuration comprised five sequential reactors (Anaerobic, Anoxic-1, Aerobic under IFAS, Anoxic-2, and Re-aeration) providing distinct redox conditions. Influent concentrations averaged 112.6 ± 49.5 µg L −1...
Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...
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...
