Jaguar Range‐Wide Connectivity: Prioritising Core Areas and Corridors Between and Within Protected Areas and Indigenous LandsNARA Subscribed
Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...
This paper presents a comprehensive analysis of the lithic assemblage from Level G1 of El Cierro Cave (northern Spain), attributed to the Cantabrian Lower Magdalenian. The study comprises 2,829 items, including 2,800 knapped artefacts, six macrolithic tools and 23 unmodified pebbles. Lithic procurement is dominated by flint, followed by quartzite and minor amounts of quartz. Eleven flint types have been identified, with local...
In El Bagre, Nechí, Zaragoza, and three other municipalities that comprise the Bajo Cauca region of Antioquia, an estimated total of 28.000 ha have been affected by illegal gold mining, where environmental liabilities such as mine tailings are distributed throughout the area. Urban areas, especially the main urban centers, may be exposed to environmental contaminants and their associated adverse effects. Studies that contribut...
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...
Identification of Genetic Variation Associated With Heat Tolerance in Cowpea ( Vigna unguiculata L. Walp.)NARA Subscribed
Heat tolerance is an important trait in cowpea, a crop that is the primary protein source for a large portion of the human population in sub‐Saharan Africa. Cultivated, landrace, semi‐wild, and wild cowpea grow across the region in diverse climatic conditions. This study used environmental association (envGWAS) and allele‐frequency outlier approaches across a panel of 580 gene bank accessions to identify genomic regions associ...
Hybridization between widespread species and narrow endemics poses a serious conservation threat, often leading to extinction via genetic swamping. In this study, we applied an integrated approach—combining genetics, morphometrics, and functional ecology—to investigate the implications of hybridization between the widespread species Limonium cossonianum and the Critically Endangered L. estevei . We combined molecular markers (...
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...
Vasculogenic potential of adipose tissue derived stem cells from patients with chronic spinal cord injury and pressure injuriesNARA Subscribed
Limited vascularization and ischemia are major contributors to the chronicity of wounds, such as ulcers and traumatic injuries, which impose significant medical, social, and economic burdens. These challenges are particularly pronounced in patients with spinal cord injury (SCI), a disabling condition associated with vascular dysfunction, infections, and impaired peripheral circulation, complicating the treatment of pressure in...
