Urban freshwater systems are increasingly recognised as critical conduits for microplastic pollution, however, the interactions between land use, hydrology and microplastic transport remain poorly understood, particularly in developing countries. To address this gap, we investigated the relationships between catchment characteristics and the temporal and spatial variations in microplastic concentrations and fluxes in an urban...
Predictions of southern migration timing in coastal sharks under future ocean warmingNARA Subscribed
Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from summer habitats in the Northwest Atlantic Ocean. We then forecasted how migratory ti...
Voxel-wise insights into early Alzheimer’s disease pathology progression: the association with APOE and memory declineNARA Subscribed
Longitudinal investigation of the Apolipoprotein E (APOE) genotype’s impact on Alzheimer’s disease (AD) biomarker progression, focusing on amyloid beta (Aβ) accumulation and gray matter (GM) atrophy, integrating cognitive decline and baseline levels. Longitudinal florbetapir-PET and T1-weighted MRI data from 100 cognitively normal (CN) and mild cognitive impaired (MCI) participants both with considerable global Aβ accumulation...
Environmental Health and Societal Wealth Predict Movement Patterns of an Urban CarnivoreNARA Subscribed
How societal, ecological and infrastructural attributes interact to influence wildlife movement is uncertain. We explored whether neighbourhood socioeconomic status and environmental quality were associated with coyote ( Canis latrans ) movement patterns in Los Angeles, California and assessed the performance of integrated social–ecological movement models. We found that coyotes living in more anthropogenically burdened region...
Complementary value of molecular, phenotypic, and functional aging biomarkers in dementia predictionNARA Subscribed
DNA methylation age (MA), brain age (BA), and frailty index (FI) are putative aging biomarkers linked to dementia risk. We investigated their relationship and combined potential for prediction of cognitive impairment and future dementia risk using the ADNI database. Of several MA algorithms, DunedinPACE and GrimAge2, associated with memory, were combined in a composite MA alongside BA and a data-driven FI in predictive analyse...
Vulnerability of Ecosystem Services and Functions of Elephant Marsh, Malawi, to Land Use and Land Cover ChangeNARA Subscribed
Elephant Marsh is among the Ramsar sites in Africa that exist in complex conditions where its ecosystem services and functions (ESFs) have changed in time and space. The past 24 years have seen it being exposed to various threats instigated by land use/land cover changes (LULCC). Assessing its vulnerabilities under LULCC scenarios is essential in understanding the trajectory of its ESFs and for framing practical policy respons...

Spatial variability in stable isotopes from Lesotho surface waters: insights into regional moisture transportNARA Subscribed
Precipitation in Lesotho is highly spatially variable, a feature of the high altitude and rugged topography. The hydroclimate dynamics, despite being critical to the water security of Lesotho and adjacent South Africa, are poorly understood. Ratios of oxygen and hydrogen isotopes in meteoric water are excellent tracers of hydroclimatic processes. This study presents the first analysis of stable isotopes from surface waters in...
