Periodical cicada ( Magicicada spp.) ranges have continued to decline even as their habitat has rebounded from historic lows. This counterintuitive trajectory may be a consequence of Magicicada 's limited dispersal capabilities combined with their requirement that individual host trees survive across decades. Indeed, we find that the presence of Magicicada breeding populations is best predicted by tree cover in 1930, not by pr...
Introduction Ringed seals ( Pusa hispida ) are sentinel species of Arctic change, yet baseline microbiome data across their circumpolar range remain limited. Methods We profiled nasal and anal microbiomes from 90 free-ranging ringed seals across eight Arctic and sub-Arctic locations in Canada using 16S rRNA gene amplicon sequencing. Results Body site was the primary determinant of microbiome structure, with nasal and anal asse...
Oblong turtles hybridise with an introduced congener and display a size-heterozygosity relationshipNARA Subscribed
Freshwater turtles are among the most imperilled vertebrate groups globally, facing compounding threats from habitat loss, climate change, and invasive species. We conducted the first comprehensive range-wide genomic assessment of the oblong turtle ( Chelodina oblonga ; Indigenous Noongar: Yaakan and Booyi), a species endemic to the rapidly drying biodiversity hotspot of southwestern Australia. To evaluate individual and popul...
Early detection through mammographic screening plays a central role in improving breast cancer outcomes, with diagnostic accuracy relying heavily on radiologist performance. While experience and case volume are recognised contributors to accuracy, the specific effect of weekly mammogram reading hours (HPW) remains unclear. This study examined the relationship between HPW and diagnostic performance among BreastScreen (BS) radio...
Amazon Dry Season Will Lengthen Under Future ClimateNARA Subscribed
The Amazon rainforest is a key component of the Earth system, regulating regional climate, sustaining high biodiversity and carbon stocks. However, it is threatened by climate and land‐use changes. In recent decades, the region has experienced intensified droughts and heatwaves, trends expected to worsen under future warming. In this study, we assess how the timing, length, and spatial distribution of the dry season across the...
A primary care pharmacogenetic precision medicine pilot based on specific Māori tribal ethical frameworks and principlesNARA Subscribed
Indigenous tribal communities are frequently underserved by genomic medicine because they are under-represented in research, often live in remote locations and have ethical and cultural perspectives that vary from westernised standpoints. The Rakeiora platform, a permissioning and analytical environment that incorporates Māori perspectives and ethical frameworks on how precision medicine research is best conducted was used to...
Effect of six weeks ubiquinol supplementation on mitochondrial respiratory function and exercise capacity in healthy malesNARA Subscribed
Coenzyme Q10 (CoQ 10 ) is an integral component of the mitochondrial electron transfer system. Most studies have administered the oxidised form of CoQ 10 (ubiquinone) and observed no effects on mitochondrial respiratory function or endurance exercise performance. The reduced form of CoQ 10 , ubiquinol (UQH 2 ), has greater bioavailability than ubiquinone, but the effects of UQH 2 supplementation on mitochondrial respiratory fu...
Multimorbidity as a predictor of mortality in companion dogsNARA Subscribed
An Integrated Biostratigraphy and Chemostratigraphy for the Dawn of the Jurassic (the Hettangian Stage in the Cheshire Basin, UK)NARA Subscribed
Highly resolved Earth System reconstructions of the Earliest Jurassic are hampered by complexities of existing reference sections. Here, an integrated stratigraphy of two core records is constructed, representing the expanded Hettangian sequence of the Cheshire Basin, UK. The combined record is based on ammonite and calcareous nannofossil biostratigraphy, organic carbon isotope ratios, and bulk rock chemical properties of lega...
Since the early 2000's, Modern Coexistence Theory (MCT) has guided empirical investigations of coexistence. We reviewed empirical applications of MCT to answer two questions: (1) What have we learned about the strength of temporal, spatial and variation‐independent mechanisms of coexistence in nature? (2) How have studies of niche and fitness differences advanced our understanding of coexistence? With respect to the first ques...
