The sacred kingfisher Todiramphus sanctus is a widespread bird species that is non-migratory in New Zealand, in contrast to elsewhere in the world. We describe a new species of Skrjabinoclava , a genus of acuariid nematodes, recovered from the oropharynx of sacred kingfishers in New Zealand. This is the first record of Skrjabinoclava in Australasia and the first publicly available DNA sequence for the genus. Skrjabinoclava pha...
Thermal tolerance and acclimation limits in bull trout ( Salvelinus confluentus ) alevinNARA Subscribed
The critical thermal maximum ( CT max ) of bull trout ( Salvelinus confluentus ) alevin was measured after 3 weeks of acclimation to 4–21°C. CT max increased from 24.3 at 4°C to 26.7 at 9°C, plateaued between 9 and 12°C (26.9°C), and declined to 25.9°C at 15°C. Acclimation mortality increased above 12°C, reaching 53.7% at 15°C, and no fish survived at 18–21°C. Condition factor declined at ≥12°C. Results indicate bull trout ale...
Normalization method for relative cerebral blood flow influences sex and cognitive status effects in nondemented older adultsNARA Subscribed
Cerebral blood flow (CBF) is lower in males than females in cortical gray matter, but these sex effects are unknown in the hippocampus. Potential interactions between sex and cognitive status on CBF, which may contribute to the greater risk for females to develop mild cognitive impairment (MCI), are also understudied. Moreover, these effects may vary when regional CBF is normalized relative to individual differences in referen...
Corporations and financial institutions driving coastal conflicts involving Indigenous PeoplesNARA Subscribed
Socio-environmental conflicts associated with large-scale economic projects in Indigenous territories are well documented, but conflicts in coastal areas remain largely unexplored, despite the crucial differences between inland and coastal ecosystems. While the empirical literature about socio-environmental conflicts in Indigenous territories in coastal areas is growing, the role of financial institutions and corporations in t...
Methods for investigating trace metal speciation and partitioning in mangrove sediments: a systematic quantitative literature reviewNARA Subscribed
Purpose Mangrove rhizosphere sediments are strong sinks for trace metals, yet conventional sampling and analytical approaches often lack the resolution to capture the fine-scale biogeochemical processes driving metal immobilisation. This review evaluates the limitations of common methodologies used to study trace metal speciation and partitioning in mangrove sediments and provides recommendations for best practices. Methods A...
Radon is an established lung carcinogen, but more research is needed to inform whether area-based measures of radon exposure reflect underlying cancer risk. This study, the first of its kind in the UK, aimed to investigate the association between a nationwide indicative radon atlas and lung cancer risk in Northern Ireland, a region in which lung cancer screening programmes are under design. A population-based case–control stud...
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...
The Damaraland mole-rat ( Fukomys damarensis ) is a cooperatively breeding rodent primarily inhabiting sandy soils of southern Africa. It has the largest distribution of all the species in the genus Fukomys , from northwestern South Africa to Zambia, and from central Namibia across to western Zimbabwe. To the north of the Zambezi River in Zambia, it is replaced by its sister species Micklem’s mole-rat ( Fukomys micklemi ). Des...
Nutrient Transfer Dynamics of Anadromous Alewives (Alosa pseudoharengus) in Freshwater Spawning and Nursery HabitatsNARA Subscribed
River herring (alewife, Alosa pseudoharengus and blueback herring, A . aestivalis ) can act as vectors of nutrient transfer between marine and freshwater environments. Adult river herring can transfer marine-derived nutrients to freshwater ecosystems during spawning migrations through excretions and direct consumption of adults, eggs, and early phase juveniles by freshwater scavengers and predators. Adults and juveniles can tr...
Shallow seasonal stratification ameliorates coral bleaching during record-breaking marine heatwaves in a marginal subtropical systemNARA Subscribed
Marine heatwaves are intensifying globally, with the Fourth Global Coral Bleaching Event (GCBE) beginning in 2023, yet coral bleaching outcomes remain highly variable across space and time. This study examines the role of fine-scale thermal variation in shaping bleaching impacts during two record-breaking marine heatwaves (2022 and 2024) affecting shallow coral assemblages in the marginal and urbanised environments of Hong Kon...
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...
