A global dataset of terrestrial biological nitrogen fixation A global dataset of terrestrial biological nitrogen fixation
Biological nitrogen fixation (BNF) is the main natural source of new nitrogen inputs in terrestrial ecosystems, supporting terrestrial productivity, carbon uptake, and other Earth system processes. We assembled a comprehensive global dataset of field measurements of BNF in all major N-fixing niches across natural terrestrial biomes derived from the analysis of 376 BNF studies. The...

Global terrestrial nitrogen fixation and its modification by agriculture Global terrestrial nitrogen fixation and its modification by agriculture
Biological nitrogen fixation (BNF) is the largest natural source of new nitrogen (N) that supports terrestrial productivity1,2, yet estimates of global terrestrial BNF remain highly uncertain3,4. Here we show that this uncertainty is partly because of sampling bias, as field BNF measurements in natural terrestrial ecosystems occur where N fixers are 17 times more prevalent than their...

Using long-term ecological datasets to unravel the impacts of short-term meteorological disturbances on phytoplankton communities Using long-term ecological datasets to unravel the impacts of short-term meteorological disturbances on phytoplankton communities
Extreme meteorological events such as storms are increasing in frequency and intensity, but our knowledge of their impacts on aquatic ecosystems and emergent system properties is limited. Understanding the ecological impacts of storms on the dynamics of primary producers remains a challenge that needs to be addressed to assess the vulnerability of freshwater ecosystems to extreme weather

Identifying preferential flow from soil moisture time series: Review of methodologies Identifying preferential flow from soil moisture time series: Review of methodologies
Identifying and quantifying preferential flow (PF) through soil—the rapid movement of water through spatially-distinct pathways in the subsurface—is vital to understanding how the hydrologic cycle responds to climate, land cover, and anthropogenic changes. In recent decades, methods have been developed that use measured soil moisture time series to identify PF. Because they allow for...

Rapid butterfly declines across the United States during the 21st century Rapid butterfly declines across the United States during the 21st century
Reports of declining insect populations have received widespread media attention, but evidence for declines has been variable across regions and taxonomic groups. Edwards et al. examined trends in the most surveyed taxon: butterflies (see the Perspective by Inouye). Combining data from 35 citizen science programs across the continental US, the authors found declines in overall butterfly...

A survey of mammal and fish genetic diversity across the global protected area network A survey of mammal and fish genetic diversity across the global protected area network
Global conservation targets aim to expand protected areas and maintain species’ genetic diversity. Whether protected areas capture genetic diversity is unclear. We examined this question using a global sample of nuclear population-level microsatellite data comprising genotypes from 2513 sites, 134,183 individuals, and 176 mammal and marine fish species. The genetic diversity and...

Impact of thermoelectric power plant operations and water use reporting methods on thermoelectric power plant water use Impact of thermoelectric power plant operations and water use reporting methods on thermoelectric power plant water use
Thermoelectric power generation accounts for over 41% of total U.S. freshwater withdrawals, making understanding the determinants of power plants’ water withdrawals (WW) and consumption (WC) critical for reducing the sector’s reliance on increasingly scarce water resources. However, reported data inconsistencies and incomplete analysis of potential determinants of thermoelectric water...

Developing a probabilistic tsunami hazard assessment framework for Pacific sources: USGS Powell Center meeting summary Developing a probabilistic tsunami hazard assessment framework for Pacific sources: USGS Powell Center meeting summary
Multi-organizational principal investigators formed a U.S. Geological Survey (USGS) Powell Center Working Group (WG), Tsunami Source Standardization for Hazards Mitigation in the United States, to develop a comprehensive series of sources capable of generating tsunamis that could impact U.S. state and territory coastal areas using probabilistic tsunami hazard analysis (PTHA). PTHA...

A fire deficit persists across diverse North American forests despite recent increases in area burned A fire deficit persists across diverse North American forests despite recent increases in area burned
Rapid increases in wildfire area burned across North American forests pose novel challenges for managers and society. Increasing area burned raises questions about whether, and to what degree, contemporary fire regimes (1984–2022) are still departed from historical fire regimes (pre-1880). We use the North American tree-ring fire-scar network (NAFSN), a multi-century record comprising...

Spatiotemporal synchrony of climate and fire occurrence across North American forests (1750-1880) Spatiotemporal synchrony of climate and fire occurrence across North American forests (1750-1880)
Aim Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre-1880) fire records limits our ability to understand long-term continental fire-climate dynamics. The goal of this study is to use tree-ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and...
