The seasonality of forage production is one of the main challenges in semi-arid regions, where environmental conditions limit agricultural productivity. One promising option is the use of elephant grass ‘BRS Capiaçu’, together with deficit irrigation. This study evaluated the impact of different irrigation depths with brackish water (50%, 75%, 100% and 125% of the reference evapotranspiration – ET 0 ) on the productive, physio...
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 Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex ( Thamnomanes caesius and T. schistogynus ) to disentangle the relative contributions of riverine barriers and historical climatic fluctuations to diversification, using large specimen sampling across their entire distribu...
Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)NARA Subscribed
During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ongoing climate change. In this paper, we combine lithostratigraphy, targeted foraminiferal...
Physiological and Proteomic Shifts in Pfaffia glomerata Under Drought and Elevated CO₂NARA Subscribed
Drought is a major constraint to plant growth and productivity, and rising atmospheric CO₂ concentrations are expected to modify plant responses to water limitation. However, how CO₂ enrichment reshapes the physiological, metabolic, and molecular regulation of specialized metabolite production under drought remains poorly understood. Here, we investigated the combined effects of elevated CO₂ (e[CO₂]) and drought on plant morph...
The plant ontology of cell typesNARA Subscribed
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...
A case for monitoring fungi of clinical relevance at beaches: enterococci measures do not correlate with all disease risksNARA Subscribed
Fungal disease is on the rise, coupled with fungal pathogens increasing in geographic range. Studies have shown that viable fungal pathogens may be present in beach sand and water, and consequently, efforts are ongoing in Europe to develop guidelines for fungi levels at beaches. In the USA, fungal diseases are a growing concern, and yet, they are not subject to public health reporting, and beach environments are currently not...
