The cave of Les Pradelles (Marillac‐le‐Franc, France) was repeatedly visited by Neandertals ~55 000 years ago and is a key site in discussions of Neandertal cannibalism. Excavations between 1967 and 1980 (Vandermeersch) and between 2001 and 2013 (Maureille/Mann) produced a rich faunal assemblage (>20 000 bones), alongside Quina Mousterian tools. Here, we provide a combined study of both collections integrating ZooMS (Zooarchae...
A New Species of Arthropteris From SamoaNARA Subscribed
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly 4 cm wide); fronds monomorphic with all pinnae distinctly lobed (vs. weakly dimorphic, sterile pinnae with subentire margins and fertile pinnae a...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
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...
Experimental drought consistently underestimates productivity responses to natural drought in four Central US grasslandsNARA Subscribed
Climate change is increasing the frequency and severity of droughts globally, and grasslands are particularly vulnerable to such hydrological extremes. Drought effects at the ecosystem scale have been assessed both experimentally and through the study of naturally occurring drought, with emerging evidence that the magnitude of drought effects may vary depending on the approach used. We took advantage of a decadal study of four...
Environmental Heterogeneity Imposed by Photovoltaic Array Alters Grassland Soil Microbial CommunitiesNARA Subscribed
The rapid expansion of photovoltaic (PV) energy production has generated concern over its potential ecosystem impacts. PV arrays induce unique microenvironmental conditions by altering resource availability and substantially impacting aboveground processes. However, the belowground consequences of PV development are understudied, limiting our understanding of overall ecosystem impacts. Here, we paired soil physiochemical, mole...
Extreme Drought Decreases the Stability of Above‐ but Not Below‐Ground Productivity Across Eurasian SteppesNARA Subscribed
Ecological stability plays a crucial role in determining the sustainability of ecosystem functioning and nature's contribution to people. Although the disruptive effects of extreme drought on ecosystem structure and functions are widely recognized, their effect on the stability of above‐ and belowground productivity remains understudied. We assessed the effects of drought on ecosystem stability using a 3‐year drought experimen...
Plio‐Pleistocene Climatic Fluctuations and Divergence With Gene Flow Drive Continent‐Wide Diversification in an African BirdNARA Subscribed
Diversification mechanisms in Sub‐Saharan Africa have long attracted research interest, with varying support for either allopatric or parapatric models of speciation. However, studies have seldom been performed across the entire continent, a scale which could elucidate the relative importance of allopatric and parapatric models of divergence. To shed light on continental‐scale patterns of African biogeography and diversificati...
Determinants of riverine migration success by Atlantic salmon ( Salmo salar ) smolts from rivers across the UK and IrelandNARA Subscribed
There is some evidence that the river migration success of Atlantic salmon smolts, on their first migration to sea, varies both spatially and temporally. However, we have only a poor understanding of what may be driving this variation. In this study, we used acoustic telemetry to quantify the spatial and temporal variations in river migration success in Atlantic salmon smolts on their first migration to sea. In total 4120 Atla...
Voxel-wise insights into early Alzheimer’s disease pathology progression: the association with APOE and memory declineNARA Subscribed
Longitudinal investigation of the Apolipoprotein E (APOE) genotype’s impact on Alzheimer’s disease (AD) biomarker progression, focusing on amyloid beta (Aβ) accumulation and gray matter (GM) atrophy, integrating cognitive decline and baseline levels. Longitudinal florbetapir-PET and T1-weighted MRI data from 100 cognitively normal (CN) and mild cognitive impaired (MCI) participants both with considerable global Aβ accumulation...
Extreme Drought Increases the Temporal Variability of Grassland Productivity by Suppressing Dominant GrassesNARA Subscribed
Extreme droughts are intensifying, yet their impact on temporal variability of grassland functioning and its drivers remains poorly understood. We imposed a 6‐year extreme drought in two semiarid grasslands to explore how drought influences the temporal variability of ANPP and identify potential stabilising mechanisms. Drought decreased ANPP while increasing its temporal variability across grasslands. In the absence of drought...
