The locus coeruleus (LC), the earliest site of tau accumulation in Alzheimer’s disease, directly influences pupillary and vergence oculomotor systems. Whether task-evoked oculomotor dynamics can non-invasively differentiate AT(N) profiles, A+T+ (biological Alzheimer’s disease) and A−T+ (suspected non-Alzheimer’s tauopathy), remains unexamined despite their differential impact on LC-mediated modulation and cortical network inte...
Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean EstuaryNARA Subscribed
Subterranean estuaries (STEs) are key bioreactors regulating the quantity and chemical composition of groundwater‐derived nitrogen (N) reaching coastal ecosystems. Yet, the microbial controls on N‐cycling within these groundwater–seawater mixing zones remain poorly understood. We investigated the spatio‐temporal variations in microbial communities and their N‐cycling potential within an alluvial Mediterranean STE with high N c...
Coastal areas play a critical role in the well-being of communities worldwide. The Mediterranean basin is a climate change hotspot and contains several vulnerable, low-lying areas such as the Ebro Delta (Northeast Spain). In this study, CMIP6 wind projections from 19 GCMs are used to obtain medium-to-high resolution wave conditions for 2070–2100 in the North-Western Mediterranean, and very-high resolution wave data near the Eb...
Forest Heterogeneity by Chain Saw: How Between‐Patch Variation in Old Growth Attributes Changes the Metacommunities of BeetlesNARA Subscribed
Metacommunity theory has expanded our understanding of how spatial dynamics and local interactions influence species communities. Different assembly archetypes, reflecting different roles of species differences, habitat differences, and dispersal have been described, but we lack empirical studies specifically in terrestrial habitats testing which archetype is most important. In a replicated design, we experimentally enhanced s...
Modern vegetation and its pollen spectra in the Cantabrian mountains, northern Iberian Peninsula, compared with fossil pollen recordsNARA Subscribed
The study of the pollen rain from modern vegetation has greatly improved the interpretation of pollen diagrams and our understanding of ancient plant communities. In this study, 76 pollen samples were studied from various vegetation types in Cantabria, northern Iberian Peninsula. The pollen signals of the main taxa were compared to their estimated spatial coverage at various scales (100 m, 1 km and 5 km from the sampling point...
Historical insights, current challenges: tracking marine biodiversity in an urban harbor ecosystem in the face of climate changeNARA Subscribed
The Boston Harbor Islands is the only coastal drumlin archipelago in the USA, featuring a distinctive and uncommon geological intertidal habitat known as mixed coarse substrate, which supports a range of coastal species and ecological processes. Recently designated as one of America’s 11 most endangered historic places due to climate change impacts, coastal adaptation and restoration efforts are crucial to their preservation....
