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...
Constructive engagement with farming stakeholders around diffuse nutrient pollution remains an ongoing global sustainability challenge. Using a participatory action-research approach, this study integrates multi-year, high-frequency nitrate-sensing across three North Queensland sugarcane catchments (Herbert, Tully and Russell-Mulgrave) to examine whether digital sensing technologies, by delivering water quality information at...
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...
Symbiotic relationships between microbes and hosts frequently involve the assembly of complex microbial communities. Community‐level patterns influence life‐history traits, ecological trajectories of partners, and are often critical for host health. These patterns are driven by mechanisms acting at the individual level, including microbial dispersal, host selection, and microbe–resource interactions. Critically, we still lack...
Infectious agents shape fish populations by inducing lethal and sublethal changes that alter nutrient metabolism and metal bioaccumulation. These shifts can manifest as changes in the ionome—the specific combination of essential and non-essential chemical elements defining the whole-body composition of an individual. Understanding how pathogens shape the fish ionome is critical for developing advanced monitoring tools and clar...
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...
A Review of Phage Therapy for Aquaculture Applications: Efficacy, Health Ramifications and Research ChallengesNARA Subscribed
The emergence of antimicrobial resistance has encouraged a reappraisal of bacteriophage therapy for the mitigation of bacterial diseases in different environmental settings, including aquaculture. Here, we review aquaculture applications of phage therapy by considering its efficacy and potential for broader host‐associated effects, including host immunity, microbiome composition and behaviour. The advantages of phage therapy f...
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...
A comparison of dating models for reservoir sediment records using mass accumulation, radioisotopes, and Bayesian statisticsNARA Subscribed
Paleolimnological investigations of reservoirs (i.e. human-made lakes) are becoming more common, establishing a need to explore dating approaches for sediment records from reservoirs. Traditional dating methodologies such as Constant Rate of Supply (CRS), 137 Cs, and Mass Accumulation Rate (MAR) have been utilized for sediment records from reservoirs for decades. However, with the advent of newer Bayesian approaches, such as t...
