Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye ( Sander vitreus )NARA Subscribed
Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye ( Sander vitreus ) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to assess temporal changes in carbon (δ 13 C) and nitrogen (δ 15 N) and pulverized th...
Uncovering correlates of decline and critical refuges for a threatened terrestrial mammalNARA Subscribed
Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with persistence to inform conservation planning and management. We integrated changes in realized...
Emerging infectious diseases threaten wildlife globally, yet standard surveillance often relies on lethal sampling, an approach that can conflict with conservation priorities. The recognised threat of Ranavirus ( Rv ) to amphibian populations exemplifies this challenge, highlighting the urgent need for refined, non-lethal surveillance methods. Using a stepwise approach, we conducted four sequential experiments spanning laborat...
Global movement of woodwasps (Hymenoptera: Siricidae) inferred from border interception recordsNARA Subscribed
Global trade has accelerated the spread of wood-boring insects. Woodwasps (Hymenoptera: Siricidae) include several species that have established outside their native ranges, but their global translocation is not well documented. Despite several biases, port interception records can serve as indirect proxies of propagule pressure and can be used to quantify invasion pathways. Here, we use historical border interception records...
The Asia region harbors exceptional chondrichthyan (shark, ray, and chimaera) diversity but faces intense fishing pressure. The Important Shark and Ray Areas (ISRA) process provides a collaborative, evidence-based framework to identify critical habitats and inform spatial management. We assessed ISRAs across the Bay of Bengal, Southeast Asia, and the Northwest Pacific to characterize their extent, ecological significance, and...
Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a necessary part of regeneration. In some animal lineages, a second opsin functions as 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...
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of a range of environmental parameters along the length of a fibre optic cable. In this article, we review the recently emerged applications of DOFS techniques in physical oceanography and offer a perspective on the technology's potential for future growth within the field. The introduction of DOFS to physical oceanography...
