Sensitivity analysis of modeled soil water dynamics within variable rate irrigation zones for winter wheatNARA Subscribed
Understanding within-field and season variability of soil water supply and crop water stress is critical for successful variable-rate irrigation (VRI) management. The objectives of this study were to (1) assess within-field variability of field capacity (FC), wilting point (WP), total available water (TAW), and initial soil volumetric water content (VWC init ); (2) validate a water balance model based on the American Society o...
Purpose Deepwater Horizon oil spill (DWHOS) responders potentially experienced multiple stressors. We examined associations between DWHOS deployment-related stressor patterns and neurological and endocrine/metabolic conditions among U.S. Coast Guard active duty responders who completed post-deployment surveys (n = 3102). Methods Deployment-related stressor patterns were identified using principal component analysis of self-rep...
Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing and managing SPF. In response to these challenges, an international working group was f...
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...
Greenhouse gas (GHG) emissions from coastal aquaculture are an emerging environmental concern, with implications for ecosystem sustainability and climate mitigation. In this preliminary field-based study, we quantified carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous dioxide (N 2 O) fluxes from 35 randomly selected prawn farms in coastal Bangladesh, at a single time point using the floating chamber method, with concurrent...
Aquaculture in Maritime Spatial Planning Frameworks and Its Contribution to Global Food SecurityNARA Subscribed
Increase in aquaculture toward realizing the potential of the ocean as a key food provider requires comprehensive and proactive management approaches to mitigate impacts on coastal areas and to secure space for sustainable aquaculture development in both inshore and offshore areas. Maritime Spatial Planning (MSP) and Marine Functional Zoning (MFZ) are policy instruments employed in the management and regulation of multiple hum...
A New Pathogen Population Challenges the Prevention and Control of Potato Late Blight in DenmarkNARA Subscribed
Unexpected and severe outbreaks of potato late blight occurred in Denmark during the 2022 growing season due to the emergence and rapid spread of a new SSR genotype, EU43, which exhibited 100% resistance to mandipropamid. This prompted a shift in control recommendations from block applications of fungicides to fungicide mixing and alternation. Three early warning components played a critical role in the effective management of...
Regional ecosystem responses to environmental drivers in cold‐water lakes evaluated using stable isotopes of salmonid fishesNARA Subscribed
Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope measurements (carbon and nitrogen) of brown trout ( Salmo trutta , n = 2854) and Arctic charr ( Salvelinus alpinus , n = 3062) from 120 cold‐water lakes across northern Europe, spanning 0.02 to 1090 km 2 in size, to quantify the re...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
