Impacts of delayed grazing and mowing on bumblebees and flowers in species rich grasslandsNARA Subscribed
Species-rich grasslands are key habitats for bumblebees. Intensive agricultural practices such as frequent mowing and high grazing pressure have led to significant declines in floral resources in grasslands, contributing to pollinator declines. We investigated the effects of delayed mowing and delayed grazing on bumblebee and floral communities in species-rich grasslands in north-west Ireland. Using a paired field design, we m...
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...
Marine heatwaves (MHWs) are a major concern worldwide due to their increasing impacts in recent years, and these extreme events may trigger deoxygenation of coastal waters affected by sewage and eutrophication. Here we investigate the combined effects of MHWs and nutrient enrichment on the water quality and biodiversity of the Bay of Santa Catarina Island (Brazil). We used historical (1994–2020) sea surface temperature data fr...
