Neonicotinoid Levels Exceed EPA Benchmarks in Half of Waterways on Illinois Protected LandsNARA Subscribed
Neonicotinoids have become widely used pesticides due to their specificity for insects. We explored how these contaminants are distributed on protected lands within Illinois. We hypothesized that there would be lower insect biomass at sites with higher neonicotinoid concentrations which we expected to occur at sites with a higher surrounding proportion of agriculture. We predicted that neonicotinoid levels would be highest at...
Root proliferation and microbial enzyme strategies shape elevated CO₂ effects on wheat rhizosphere priming in farming soilsNARA Subscribed
Aims Elevated atmospheric CO 2 can impact soil organic carbon (SOC) cycling through increased photosynthetic carbon allocation in the rhizosphere, accelerating the decomposition of SOC (rhizosphere priming). How elevated CO 2 modifies priming intensity in different soil types and the associated microbial functional pathways remains poorly understood. Methods Using dual 13 C/ 15 N labelling, this study compared rhizosphere prim...
Growing Degree‐Day Trends Associated With ‘False Springs’ in the Continental United StatesNARA Subscribed
The warming climate has lengthened the growing season across mid‐latitude regions, driven largely by an earlier onset of the frost‐free period in spring. Earlier spring warming can advance plant phenological development but may also increase exposure to subsequent frost or freeze events that damage vulnerable new vegetative growth, commonly referred to as a ‘false spring’. We examine long‐term trends in growing degree day (GDD...
Climate and sino-nasal symptomsNARA Subscribed
Patients with sino-nasal issues often believe their symptoms are exacerbated by certain weather conditions, but these relationships are largely anecdotal. Using an extensive archive of patient surveys at the University of Virginia Rhinology Clinic from January 2010–March 2020, we examined whether sino-nasal symptoms were impacted by the weather on, or shortly before, the day of clinic visit. Clinic patients completed the Sino-...
Understanding the effects of climate change on ecological communities has been limited by a lack of general theory for how temperature affects competition. To fill this knowledge gap, we integrated Modern Coexistence Theory and the Metabolic Theory of Ecology by incorporating empirically derived temperature sensitivities into Modern Coexistence Theory's central model. We then simulated warming in consumer‐resource systems and...
Abiotic, biotic, and spatial processes shape patterns of biodiversity in coastal ecosystems. In this study, we test how these processes influence eelgrass‐associated invertebrate diversity in a subarctic seascape. We sampled invertebrate assemblages in 12 meadows along 300 km of coastline in James Bay, Canada, and tested the relative contributions of abiotic conditions, spatial arrangement, and meadow attributes in explaining...
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...
