An investigation into the diet of elephant fish ( Callorhinchus milii ) in the waters of Aotearoa/New ZealandNARA Subscribed
Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters. Its trophic ecology is poorly defined, despite its commercial and recreational importance across much of its range. This study used stomach content anal...
Organic matter respiration stoichiometry in the Arctic Ocean is linked to shifts in plankton community compositionNARA Subscribed
The global rate of ocean deoxygenation may be influenced by the molar ratio of dissolved oxygen to organic carbon consumed during microbial respiration. However, respiration stoichiometry and its environmental controls are not fully understood due to sparse direct measurements and limited global coverage. Here, we measured surface concentrations of particulate chemical oxygen demand, particulate organic carbon, and particulate...
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...
Engaging Patient Advocates to Reduce Breast Cancer Disparities: Opportunities to Advance Breast Cancer Research and EngagementNARA Subscribed
Inclusion of patient advocates in breast cancer (BC) research as experts, co-creators, and decision-makers has the potential to reduce breast cancer health disparities and enhance the implementation of clinical research. However, patient-advocates are often not included throughout the cancer care continuum. In this study, we examine the strategies of our patient advocacy training model to increase biomedical knowledge, address...
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...
Heterogeneity, Productivity, and Migration Drive Continental Evenness Patterns of Bird AssemblagesNARA Subscribed
Aim Evenness quantifies similarities in abundances among species in an assemblage and may influence processes such as species coexistence and the supply of ecosystem services. Previous work has failed to identify generalised patterns of how productivity and habitat heterogeneity influence evenness and moreover has not considered seasonal variation in evenness arising from migration. Therefore, our goal was to quantify the inte...
Effects of methamphetamine on human effort task performance are unrelated to its subjective effectsNARA Subscribed
Rationale Stimulant drugs increase objective indices of reward-related behavior, including willingness to expend effort for reward, and also produce feelings of well-being and positive mood. However, it is not known to what extent these different measures are related to each other. Objectives The present study was designed to assess the relationship between the behavioral measure of effort expenditure and positive subjective r...
Following rapid climate change, tundra plant communities are experiencing extensive compositional shifts. A conservation concern is the potential encroachment of boreal species into the tundra (‘borealisation’). Tundra borealisation has been sporadically reported, but not systematically quantified. Here, we synthesised data from across 32 study areas, spanning 1137 plots and 287 vascular plant species, resurveyed between 1981...
