Coastal waters are increasingly susceptible to low-oxygen conditions where circulation or nutrient inputs have been altered by anthropogenic activities, leading to increased occurrence of coastal hypoxia worldwide. Low-oxygen conditions also occur naturally in coastal settings, typically in bottom water or landward of sills where circulation is weak. Here we identify and characterize a persistent, low-oxygen layer in the mid-w...
Diet-dependent, beneficial and adverse effects of rapamycin on life span of Drosophila melanogasterNARA Subscribed
Rapamycin supplementation has been reported to extend life spans in numerous species, including Drosophila melanogaster , but a recent study in this laboratory revealed a marked life-shortening effect in y w male flies. The experiments reported here were performed to characterize conditions under which rapamycin could extend or shorten life spans in five fly strains. On a cornmeal/torula yeast-based medium, rapamycin extended...
Different Beta‐Diversity Frameworks Reveal Contrasting Roles of Species Abundance Distributions and Spatial AggregationNARA Subscribed
Aim Determining why community composition changes from place‐to‐place (spatial β‐diversity) is central to advancing biodiversity theory and conservation of threatened species. Spatial β‐diversity can occur most simply due to random sampling effects from the larger species‐pool, such as the random placement and distribution of individuals and species. However, ecological processes can also generate intraspecific aggregation cha...

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...
Diversification and Colonisation in the Indo‐Australian Archipelago: Genomic Insights From Colubrid SnakesNARA Subscribed
Aim The Indo‐Australian Archipelago (IAA) is one of the most geologically complex and species‐rich regions on Earth. However, our knowledge of the geological processes and dispersal mechanisms that generate archipelago‐wide distributions across the IAA is limited to a few vertebrate groups and often solely attributed to Plio‐Pleistocene sea‐level fluctuations. In this study, we use phylogenomics‐based analyses to investigate t...
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...
Micro‐Refuges or Ecological Traps: Context‐Dependent Effects of Rock Pools on Intertidal Biodiversity Across LatitudesNARA Subscribed
Aim We investigated how local‐scale environmental heterogeneity influences biodiversity patterns across broad biogeographic gradients, using intertidal microhabitats as a model system within one of the most environmentally stressful ecosystems on Earth. Location Intertidal habitats at 26 locations (two rocky shore sites per location) across six continents, spanning 98° of latitude (38°S to 60°N). Time Period 2019–2022. Major T...
Human‐induced landscape modifications and climate change are forcing wildlife into closer contact with humans as the availability of natural habitats decreases. Although the importance of anthropogenic structures for the conservation of species is widely recognized, negative narratives surrounding bats may impede conservation efforts in human‐dominated landscapes. We conducted a global systematic literature review to summarize...
Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted spatiotemporal scales. This project presents a framework for assessing the feasibility of usi...
On the 3rd April 2017 a widely felt Moiyabana earthquake shook Botswana and the rest of southern Africa. Previous Moiyabana earthquake locations used mainly teleseismic or regional seismograms; and/or non-seismic methods which include Synthetic Aperture Radar (InSAR), and magnetotelluric (MT). These results did not agree, as evidenced by the depth of the earthquake that ranged from zero to 30 km (i.e. indicating either a man-m...
Understanding fish life history is essential for effective management of fisheries, but continuous tracking over lifetime temporal scales can be difficult. Fish otoliths contain a natural biogeochemical record of ambient environmental conditions and habitat use over such scales. However, ecological interpretations of these elemental compositions can be influenced by the structural composition of calcium carbonate otoliths, whi...
Conservation of climatic refugia, or locations that will buffer vulnerable species from the effects of climate change, has recently emerged as a prominent climate adaptation strategy. Here, we introduce an important and complementary concept, ‘climatic nuclei’—locations that harbor populations of species that are expected to expand under future conditions—which has so far received little attention. While the climatic refugia c...
