The notion of people and nature as intertwined and embedded in the biosphere is gaining traction in contemporary scientific discourses. But what does it mean for a human being to be intertwined? Here, we explore this question through two lenses: looking at the human body as an open living system in continuous exchange with the chemical elements on Earth; and looking across the biosphere, at the intricate functioning of the web...
Phylogenetically Diverse Introgression Drives Subtle Population Structure in Pacific RockfishesNARA Subscribed
Genomic methods have shown that admixture and introgression are common across animal taxa. Pacific rockfishes, genus Sebastes , are a group of commercially important species that primarily inhabit inshore, shelf and slope habitats along the North American west coast. Among these, Copper and Quillback Rockfishes are closely related species known to hybridize, particularly within the Salish Sea in North America's Pacific Northwe...
Remote Spectral Detection of Canopy Functional Dimensions Varying Within and Across Forest TypesNARA Subscribed
Global trait axes reveal overarching dimensions of plant functional variation. However, how these dimensions are spatially organized within and across forest types remains unclear. We combined drone‐based full‐range imaging spectroscopy with crown‐level measurements of 16 physiological, morphological and biochemical traits across temperate, subtropical and tropical forests in China to enable spatially‐explicit trait mapping. T...
Osteoporosis, characterized by low bone mineral density (BMD) and increased fracture risk, is common yet underdiagnosed in older adults. Medications such as corticosteroids, levothyroxine, and antiepileptic drugs are well-documented contributors to BMD loss. This study examines how long-term use of these medications affects osteoporosis prevalence, specifically focusing on sex and age differences. This retrospective electronic...
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...
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...
In 2023, more than half of olive harvests ( Olea europaea ) across Spain, Greece, and Türkiye were lost to drought. The same year late freeze destroyed 90% of the peach crop ( Prunus persica ) on the Georgia Piedmont and the apple crop ( Malus domestica ) in central New York, Vermont, and southern Quebec. Climate extremes now rank with the costliest threats to agriculture, but their role in forest recovery from diebacks that a...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
A Comparison of Diving Behavior of Goose‐Beaked and Dense‐Beaked Whales From Tagging Studies in Multiple Ocean BasinsNARA Subscribed
Studies of cetacean diving behavior in multiple locations in different ocean basins allow for an assessment of variability within and among populations. We examine foraging dive behaviors of goose‐beaked whales ( Ziphius cavirostris ) and dense‐beaked whales ( Mesoplodon densirostris ) using data from 132 tagged whales in seven locations in the Pacific and Atlantic Oceans and the Mediterranean Sea. Acoustic recording tags are...
Pelagic sharks target long‐lived, retentive anticyclonic eddies in the Northwest Atlantic OceanNARA Subscribed
Open ocean ecosystems represent the largest habitat on Earth and are highly dynamic in time and space. Mesoscale eddies are a primary driver of this variability and serve a key structural role in ocean ecosystems. Eddies modulate marine biodiversity beyond their impacts on plankton, influencing many ecologically and commercially important predators that may preferentially occupy anticyclonic eddies. However, how animal‐eddy in...
Coastal managers worldwide must prepare for changes in annual wave overtopping events due to climate change and sea-level rise. Research often assesses overtopping discharges by extreme events at a sea wall crest, typically using data from physical models or empirical rules based on scaled experiments. Here, we analyse a unique 1-year field dataset of coastal wave overtopping, from SW England, to determine the number of indivi...
