Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

The Anatomical Record, EarlyView.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

Whole‐bone shape of hominoid manual proximal phalanges

The Anatomical Record, EarlyView.
Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

The role of refluxing deep hypersaline brines and evaporite precipitation dynamics in the Castile Formation and marginal carbonate strata (Delaware Basin, USA)

The Depositional Record, EarlyView.
The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

The Depositional Record, EarlyView.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

Quantification of rheological parameters in deep‐sea mining plumes

Deep Underground Science and Engineering, EarlyView.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

Lentils can Absorb Amino Acids as a Nitrogen Source Supporting Early Growth

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Lentils (Lens culinaris Medik.) are a valuable crop due to their high nutritional content, low environmental impact, and nitrogen‐fixing ability via rhizobacteria. Early in development, before this symbiosis is established, lentils require external nitrogen, typically supplied through fertilizers or already present in soils.

Hydroclimate variability in the eastern Kimberley, Australia, since the last deglaciation

Journal of Quaternary Science, EarlyView.
Abstract The climate of the Kimberley region in tropical northwest Australia is dominated by the Indo‐Australian summer monsoon (IASM). Understanding of the palaeoclimate since the Last Glacial Maximum in this region, which is well placed to record IASM variations, is currently based on few records.

Distinguishing Spiennes and Lanaye Flints Using Portable ED‐XRF to Trace Neolithic Exchange Networks in the Rhine‐Meuse Delta

X-Ray Spectrometry, EarlyView.
ABSTRACT Flint, or chert, sources in the Rhine‐Meuse delta are generally distinguished based on macroscopic characteristics such as fossil inclusions, colour variations, and translucency. Previous studies on chemical characterisations of flint sources proved challenging due to the variation and overlap between different sources. Energy Dispersive X‐ray

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...
