Conservation translocations require careful assessment of dietary resources to ensure population viability. Here, we used environmental DNA metabarcoding to characterise fungal assemblages across three major habitat types on Dirk Hartog Island, Western Australia, prior to the planned reintroduction of two threatened mycophagous species: the boodie ( Bettongia lesueur ) and woylie ( Bettongia ogilbyi ). We detected 243 fungal A...
Spent coffee ground biochar for the adsorption of phenolic compounds: influence of pyrolysis conditions and hydrolysate concentrationNARA Subscribed
This study investigates the use of biochar produced from spent coffee grounds (SCG) as an adsorbent for phenolic compounds found in sugarcane bagasse hydrolysates. SCG is an abundant sustainable and low-cost agro-industrial residue, which was evaluated as potential adsorbent for removing fermentation inhibitors commonly found in lignocellulosic hydrolysates. Biochar samples E1 to E6 were produced via pyrolysis under nitrogen a...
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...
Phosphorus and base cations drive contrasting root dynamics in a central Amazon forestNARA Subscribed
Background and aims In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root st...
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...
Dispersal is one of the most important aspects of animal behavior and can have far‐reaching consequences for organismal ecology and evolution. Despite recent theoretical advances in understanding why individuals within the same population vary in dispersal behavior, relatively few studies have empirically evaluated the long‐term causes and consequences of variable dispersal within natural populations. In this study, we used li...
Distinct patterns of endothelial response to endotoxin in aged mice as compared to young miceNARA Subscribed
Aging exacerbates organ injury in endotoxemia, but it is not clear whether endotoxemia is associated with a specific, age-related profile of the endothelial response. Therefore, the aim of the study was to assess the pattern of endothelial response to lipopolysaccharide (LPS) in aged mice (18-month-old) as compared to young mice (3-month-old). Our analysis was based on functional endothelial responses measured in vivo by magne...
