Standardized microhaplotype databases and frameworks for assessing and mining crop genetic diversityNARA Subscribed
Keymessage Standardized microhaplotype databases for eight diverse crops enable multiallelic analyses, comparative genetics, and breeding decisions. Abstract Microhaplotypes are short genomic segments that contain multiple tightly linked variants, providing multi-allelic data that can enhance genetic resolution compared to traditional biallelic single nucleotide polymorphism (SNP) markers. Here, we present the creation and uti...
The Commercial Potential of High-Oil Moringa oleifera: A Competitive Analysis for the Biofuel and SAF MarketsNARA Subscribed
The accelerating global commitment to decarbonisation has intensified the search for sustainable, high-performance feedstocks capable of supporting the growing biofuel and Sustainable Aviation Fuel (SAF) sectors. Although conventional oilseed crops such as rapeseed, soybean, sunflower, and palm oil currently dominate biodiesel production, their long-term viability is constrained by issues including yield plateaus, competition...
Bottom‐tow gear fisheries (trawls and dredges) produce ~24 million mt of harvest annually, representing a globally important animal‐sourced food system. While many are currently sustainably managed, growing concern over the potential for ecosystem impacts from bottom‐tow gears has increased pressure to improve these fisheries. We assembled an international working group of > 30 contributors, including fishing industry particip...
Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practiceNARA Subscribed
Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare. This study aims to evaluate the utility of expert elicitation for adaptive management in the New South Wales Saving our Species program in Australi...
Millennial-scale reef assemblage shifts in the Spermonde Archipelago, Makassar Strait, IndonesiaNARA Subscribed
The Coral Triangle is the region in the Indo-Pacific with the highest diversity of reef organisms. Coral reefs here have experienced increased anthropogenic stressors since the late 1970s due to destructive fishing, land reclamation, industrialization, and agriculture. Biological observations in the Spermonde Archipelago (SW Sulawesi, Indonesia) started only after large-scale disturbances had begun limiting insights into long-...
Effective conservation and enforcement strategies for marine turtles depend on understanding population structure, connectivity, and the geographic origins of turtles impacted by threats such as bycatch, overexploitation, and illegal trade. However, mitochondrial DNA (mtDNA) data remain fragmented across studies, with inconsistent sequence lengths, haplotype nomenclature, and metadata standards limiting their application in co...
Fluvial Export of Carbon and Nutrients from Boreal Catchments Disturbed by Fire and Permafrost ThawNARA Subscribed
Increased frequency and intensity of fire in the boreal forest can degrade permafrost and redistribute large pools of carbon and nitrogen that influence global climate. However, these changes are difficult to observe and predict at regional spatial scales and decadal or longer timescales. As receiving features of landscapes, streams integrate biogeochemical activity within the contributing area and might provide signals of dis...
Critical elements underpin clean-energy, electronics and catalysis, yet conventional extraction from mine waste is chemically intensive, poorly selective, and increasingly infeasible as ore/waste grades decline. Bioleaching is gaining traction, but purification from leachates remains difficult, especially for chemically similar ions such as rare-earth elements (REE) and platinum group elements (PGE). Proteins offer an alternat...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
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...
Conserving Freshwater Biodiversity in U. S. Protected Areas – Management Intervention and the RAD FrameworkNARA Subscribed
Protected areas are considered a critical antidote to global biodiversity loss. Yet, protected areas have not effectively preserved freshwater biodiversity compared to other taxonomic groups, in part because they are not designed or managed with freshwater ecosystems in mind. Additionally, historical and current human activities have degraded freshwater biodiversity, and climate driven transformation constrains the ability of...
Weedy rice is a close relative of cultivated rice ( Oryza sativa ) that infests rice fields worldwide and drastically reduces yields. To combat this agricultural pest, rice farmers in the southern US began to grow herbicide‐resistant (HR) rice cultivars in the early 2000s, which permitted the application of herbicides that selectively targeted weedy rice without harming the crop. The widespread adoption of HR rice coincided wi...
Global Patterns and Drivers of Seagrass Biomass, Net Primary Production and Meadow StructureNARA Subscribed
Aim We decipher global patterns in seagrass growth and structure to advance seagrass science, facilitate multidisciplinary research, and promote effective management strategies and policy development for seagrass habitats. Location: Global. Time period: 1975 to 2024. Major taxa studied: Seagrasses—marine angiosperms. Methods A global data set on seagrass total biomass, total net primary productivity (NPP), shoot density, and p...
