Phosphorus and base cations drive contrasting root dynamics in a central Amazon forestNARA Subscribed
Background and aims In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root st...
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...
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...
NCBI Orthologs: Public Resource and Scalable Method for Computing High-Precision Orthologs Across Eukaryotic GenomesNARA Subscribed
Orthologs are fundamental for enabling comparative genomics analyses that further our understanding of eukaryotic biology. The unprecedented increase in the availability of high-quality eukaryotic genomes necessitates scalable and accurate methods for orthology inference. The National Center for Biotechnology Information (NCBI) developed “NCBI Orthologs”, a resource and a computational pipeline designed to meet this challenge...
Redfield revisited: Insights into freshwater seston carbon : nitrogen : phosphorus stoichiometryNARA Subscribed
Seston carbon (C), nitrogen (N), and phosphorus (P) stoichiometry plays a fundamental role in aquatic ecosystems, influencing nutrient cycling, primary and secondary production, and trophic interactions. In freshwater systems such as lakes, P limitation is more common, whereas in marine environments, N more frequently limits primary production, reflecting different nutrient limitation patterns across aquatic ecosystems. The Re...
Habitat suitability assessment for native oyster based on temperature and salinity modelling in an estuarine environmentNARA Subscribed
The European flat oyster, Ostrea edulis , has been harvested in Galway Bay, Ireland, for centuries, but the oyster populations in the bay have declined and are currently facing multiple threats. One major concern in the bay is the recurrence of heavy-rainfall, high-runoff and low-salinity events. In this work, a high-resolution hydrodynamic coastal model of Galway Bay is used together with experimental data on oyster mortality...
Information Provision for Patients Who Undergo Resection of Colorectal Liver MetastasesNARA Subscribed
Information provision to patients is helpful prior to and during cancer treatment. However, the level of information required or warranted varies, and no studies have examined this in patients who have had resection of colorectal liver metastases (CRLM). The aims of this study are to assess how patients perceive information received from different healthcare providers and to examine factors that might be associated with the qu...
Nitrogen fixation may not alleviate stoichiometric imbalances that limit primary production in eutrophic lake ecosystemsNARA Subscribed
Ecosystem‐scale primary production may be proximately limited by nitrogen (N) but ultimately limited by phosphorus (P) because N 2 fixation contributes new N that accumulates relative to P at ecosystem scales. However, the duration needed to transition between proximate N limitation and ultimate P limitation remains unknown for most ecosystems, including lakes. Here we present the results of a fully replicated, multi‐annual la...
Purpose of Review Environmental chemical exposures may disrupt child development, with long-lasting health impacts. To date, U.S. studies of early environmental exposures have been limited in size and diversity, hindering power and generalizability. With harmonized data from over 60,000 participants representing 69 pregnancy cohorts, the National Institutes of Health’s Environmental influences on Child Health Outcomes (ECHO) P...
