Where does decentralised green nitrogen fit in Africa’s fertiliser resilience strategy?NARA Subscribed
Africa faces recurrent fertiliser shocks because much of its nitrogen supply depends on imported products, fossil energy, and exposed trade routes, while production, product mix, logistics, and farm-gate demand remain poorly aligned. Decentralised green nitrogen production – defined as small-scale nitrogen fertilizer synthesis powered by renewable electricity – could make a major contribution to addressing these challenge, but...
Limitations of using the canopy to infer the structure and functioning of giant kelp forestsOA Marine
Data obtained from remote sensing of floating kelp canopies are routinely used to assess changes in the distribution, structure and functioning of kelp forests. Such assessments rely on the assumption that changes in surface canopies reflect changes in the structure and functioning of the underlying kelp forests. So far there has been little attempt to validate this assumption, which raises the risk that management decisions p...
Three Decades of Silviculture in Northern Rocky Mountain Forests, USA: Trends, Practices, and OutcomesNARA Subscribed
The Northern Rocky Mountains region includes 42 million acres of forest land which is diverse in landownership, management objectives, tree species, site productivities, disturbance regimes, and silvicultural practices resulting in a mosaic landscape. Substantial changes in landownership, management objectives, markets, policy, forest conditions, and silvicultural practices have occurred over the last thirty years. This review...
The purpose of this study was to investigate the prevalence of relative age effects (RAEs) within and between U18, U21 and professional senior squads, that compete in the highest (respective) leagues within England. Birthdate, playing position and age (years) of U18 ( n = 487), U21 ( n = 350), and senior ( n = 396) players from squads competing in the highest divisions of their respective age groups were obtained. Moreover, na...
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...
Diagnosing scaling bottlenecks in 10 community conservation initiatives in southern and eastern AfricaNARA Subscribed
Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e., bottlenecks) could improve scaling strategies. We used insightsfrom 84 ex...
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...
Modeling forest restoration potential in the Scottish Highlands using multiple machine learning approachesNARA Subscribed
Natural range contraction and millennia of anthropogenic disturbance have led to a steady decline in stands of Caledonian Pine Forest (CPF) across the Scottish Highlands. Much of the land is now dominated by short-stature shrubs, with fragmented areas of native forest and commercial plantation. Several surmountable barriers exist to large-scale reforestation of the CPF, including tensions with existing economies, land ownershi...
