Archaeometry, EarlyView.Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Wildlife trade investigations benefit from multivariate stable isotope analyses
Biological Reviews, EarlyView.ABSTRACT The investigation of wildlife trade and crime has benefitted from advances in technology and scientific development in a variety of fields. Stable isotope analysis (SIA) represents one rapidly developing approach that has considerable potential to contribute to wildlife trade investigation, especially in complementing other methods including ...

Classification of direct threats to the conservation of ecosystems and species 4.0
Conservation Biology, EarlyView.Abstract Identifying and assessing the magnitude of direct threats to ecosystems and species are critical steps to prioritizing, planning, implementing, and assessing conservation actions. Just as medical clinicians and researchers need a standard way to talk about human diseases, conservation practitioners and scientists need a common and ...

Generating a Statistically Constrained Quaternary Model of a Buried Bedrock Valley Using FDEM
Groundwater, EarlyView.Abstract An airborne electromagnetic (AEM) survey was conducted using the Resolve™ frequency‐domain system over a buried bedrock valley near Elora, Ontario, Canada. A statistical bootstrapping approach was used to establish a relationship between the electrical resistivity from spatially interpolated one‐dimensional AEM resistivity models and the ...

Patterns and Drivers of Phylogenetic Beta Diversity in the Forests and Savannas of Africa
Journal of Biogeography, EarlyView.ABSTRACT Aim Studying beta diversity, or the variation in species composition among communities, can give insights into plant community assembly over space and time. If different biomes show contrasting large‐scale beta‐diversity patterns, this can indicate divergent evolutionary histories or ecological processes that then drive species turnover among ...

Journal of Anatomy, EarlyView.The study constructs a 3D whole‐body biomechanical model of the Late Triassic archosaurian reptile Lagosuchus talampayensis, which includes reconstructions of the hindlimb musculature. The process of constructing the model revealed that numerous limb bones curated with the main specimens are from other, as‐yet‐undetermined archosaurs.

Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus
Journal of Anatomy, EarlyView.We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...

Meteoritics &Planetary Science, EarlyView.Abstract Troilite is a common phase in iron meteorites, but there are limited data available for the partitioning behavior of elements between troilite and solid metal. In this study, we present the results of experiments with coexisting Fe‐Ni solid metal, an S‐rich metallic liquid, and troilite, conducted at 800–925°C in evacuated silica tubes at 1 ...

Meteoritics &Planetary Science, EarlyView.Abstract The in‐plane rotation method is used to obtain X‐ray random diffraction (XRD) patterns of polished thin sections of 10 CM chondrites. The samples include five intermediately altered CM chondrites with subtypes 2.6–2.3, two heavily altered CM chondrites with subtype 2.0 and three with secondary heating after hydration (Y 980036, Y 980051, and ...

Sedimentology, EarlyView.ABSTRACT Sedimentological analysis of the outcropping Sherwood Sandstone Group, northern Cheshire Basin, UK, documents the preserved stratigraphic expression of water table‐controlled aeolian‐dominated erg‐margin successions (Wilmslow Sandstone Formation and lower Helsby Sandstone Formation), overlain by dryland fluvial deposits (middle Helsby ...
