From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar StoneNARA Subscribed
The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain. Proposed mechanisms include Neolithic human transport via marine or overland routes or southward movement as a glacial erratic. Here,...
Decadal predictions of future habitat favourability of the European green crab (Carcinus maenas) on the Pacific Coast of North AmericaNARA Subscribed
The European green crab ( Carcinus maenas ) is a globally important invasive species. Since 1989, it has been spreading north from San Francisco Bay on the Pacific Coast of North America. Climate change is likely to lead to the species spreading further north into Alaskan and Arctic waters. Previous studies predicting its potential future distribution have focused on its range at the end of the century, under only one of multi...
The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleostNARA Subscribed
Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work. This study examined whether acute exposure to isosmotic conditions (9 ppt) lowers aerobic metabolism and enhanc...
Semi-aquatic mammals in the face of urbanization in IllinoisNARA Subscribed
Throughout their range, the North American River Otter ( Lontra canadensis ), Common Muskrat ( Ondatra zibethicus ) and North American Beaver ( Castor canadensis) , have been exploited for their fur for centuries, leading to local-scale extirpations. More recently, these species have begun to return to landscapes where they have been absent since the commercial fur trade. The reappearance of these species in human-dominated, h...
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...
The complex population structure of Tamanend's bottlenose dolphins ( Tursiops erebennus ) along the U.S. Mid‐Atlantic coast complicates assessment of their bycatch. To improve our understanding of the stock identity of individual dolphins taken as bycatch in this region, we compared images of the dorsal fins of bottlenose dolphins that stranded with evidence of fishery interactions (FI+) to the Mid‐Atlantic Bottlenose Dolphin...
Success of restoration strategies in preventing extirpation of 2 critically endangered coral speciesNARA Subscribed
An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral ( Acropora palmata ) and staghorn coral ( Acropora cervicornis ), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species occurred in outplanted populations, in o...
New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target. However, there is a lack of species occurrence data to support evidence of where biodiversity can be best protected. To address t...
