Contrasting stem NSC dynamics in evergreen and deciduous conifers of a Siberian mixed forestNARA Subscribed
Key message Siberian evergreen conifers maintain stable starch reserves, while deciduous larch adopts a dynamic carbon strategy with autumn NSC accumulation to fuel spring growth, enhancing boreal forest resilience. Abstract Non-structural carbohydrates (NSC) play a fundamental role in tree growth, metabolism, and resilience by buffering temporal imbalances between carbon supply and demand. However, comparative studies integra...
Building better homes for pollinators using native-based landscapes in new suburban developmentsNARA Subscribed
Maintaining healthy pollinator communities is vital for both agricultural and natural ecosystems, but there are many threats to pollinator communities globally. Urbanization is a one of these major threats, but urban green spaces present opportunities for pollinator conservation. The effectiveness of designed urban landscapes in supporting pollinators largely depends upon plant selection and design, and there is an increasing...
Resident and Migratory Falcons' Breeding Phenology and Productivity Respond Differently to Weather and Climate Change Across the ArcticNARA Subscribed
Climate change is disproportionately warming the Arctic, leading to changes in weather patterns that affect breeding phenology for many Arctic species. Despite extensive research on non‐predatory birds, few studies have examined the impacts of climate change on higher trophic levels, especially those comparing breeding phenology and productivity between migratory and resident species. Our study used long‐term monitoring data f...
Land use influences dissolved organic matter composition in the U.S. Coastal Critical Zone NetworkNARA Subscribed
Coastal watersheds are highly productive biogeochemical systems supporting robust coastal fisheries and contributing significantly to the marine gross primary production flux. These ecosystems are comprised of civil infrastructure, farms, forests, and marshes, and their diversity is reflected in the quantity and quality of dissolved organic matter (DOM). Here, we assess the role of farming in influencing DOM from surface water...
Global patterns and regional insights into kelp forest protection, restoration, and stewardshipNARA Subscribed
Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
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...
Unprecedented Burning in Tropical Peatlands During the 20th Century Compared to the Previous Two MillenniaNARA Subscribed
Tropical peatland wildfire incidence has risen in recent decades, driven by drainage for land use and intensified by severe droughts with global climate change. These disturbances have altered vegetation structure, disrupted ecosystem functioning, and increased carbon emissions, particularly in Southeast Asia. However, the long‐term history and characteristics of wildfires in tropical peatlands remain largely unknown. Here, we...
Modeling Ringed and Bearded Seal Future Habitats Indicates Stability, Shifts, and RefugiaNARA Subscribed
Understanding how marine habitats are changing with a warming Arctic is essential for conservation, management, and adaptation strategies bearing tangible consequences for Arctic communities and ecosystems. Ringed seals and bearded seals rely on specific ice and snow conditions to support critical life history events affecting survival and reproduction. Here, we develop a panarctic habitat suitability model linking life events...
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...
