Aim Energy availability is often assumed to be a primary driver of variation in biodiversity across large‐scale environmental gradients such as elevation, but support for the role of energetic constraints is far from universal. Here, we assume that these variations in energy–richness relationships might arise from the degree of match between the scale of the response of organisms to energy (response scale) and the scale of the...
Multi‐Model Ensembles in Ecosystem Modeling: Challenges and Best Practices for Decision‐MakingNARA Subscribed
Ecosystem models are increasingly central to the decision‐making for environmental policy, conservation planning, and climate‐related investments. Yet, the growing reliance on Multi‐Model Ensembles (MMEs) of ecosystem models by practitioners and policymakers, sometimes under tight timelines and imperfect information, has frequently outpaced the scientific rigor required to ensure ensemble reliability. Here, MMEs refer to appro...
Characterizing pancreatic cancer-associated fibroblast heterogeneity in vascular microphysiological systemsNARA Subscribed
Pancreatic Ductal Adenocarcinoma (PDAC), one of the deadliest cancer types, is dominated by a tumor microenvironment (TME) that is desmoplastic, immunosuppressive, and generally unresponsive to conventional cancer treatments. Cancer-Associated Fibroblasts (CAFs) are thought to drive many of the features of PDAC that contribute to treatment resistance, yet CAFs exhibit wide phenotypic heterogeneity with unclear biological and c...

Widespread non-target-site resistance in Setaria viridis to four classes of herbicideNARA Subscribed
Key message Although herbicide resistance in Setaria is rampant and cosmopolitian across four herbicide families, we encountered little evidence of target-site resistance, indicating diverse non-target mechanisms of metabolizing, sequestering, and overwhelming herbicides. Abstract Setaria viridis is a cosmopolitan weed and model genetic system with increasing reports of resistance to multiple classes of herbicides. Our goal wa...
Observation‐Constrained Agroecosystem Model Inversion Reveals Continental‐Scale Variation of Winter Wheat TraitsNARA Subscribed
Understanding how crop trait variability shapes genotype × environment × management (G × E × M) interactions remains a key uncertainty in predicting agricultural performance under a changing climate. Continental‐scale crop models commonly rely on spatially uniform parameters, limiting their ability to represent adaptive variation in phenology, allocation, and yield formation. Here we integrate the mechanistic agroecosystem mod...
Evolution of lagoon formation and desiccation along the southeast Caspian coast: A historical and modern perspectiveNARA Subscribed
The southeastern Caspian coast, a climate transition zone from subtropical to arid conditions and host to several Ramsar wetlands, is highly sensitive to Caspian sea‐level (CSL) fluctuations and climate change. This study investigates the environmental evolution and resilience of the Gomishan Lagoon by integrating paleoenvironmental archives, instrumental observations, re‐analysis data sets, satellite imagery, and future clima...
Purpose This study investigated foliar-applied silicon dioxide (SiO 2 ), alone and with calcium (Ca), as a sustainable strategy to enhance lettuce quality and performance, using a genetically diverse panel of accessions for broad applicability. Methods We conducted multi-year outdoor pot and field experiments to assess the effects of a range of SiO 2 and Ca concentrations and a promising subset of treatments, respectively....
Our study on the composition and functional groups of soil fungi in phosphate mine spontaneous recovery areas has identified several fungal genera that play a crucial role in soil regeneration. This finding carries significant practical implications for the methodologies employed in mine site reclamation. We used amplicon sequencing‐based high‐throughput sequencing (HTS) and traditional fungal culturing methods in the Kunyang...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
