Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Arterial Spin Labeling: a non-invasive approach for estimating perfusion in Multiple Sclerosis.

reservedMultiple sclerosis (MS) is a neurodegenerative disorder affecting the central nervous system. The process of demyelination lies at the core of this condition, which can lead to the formation of plaques. The disease progresses from an inflammatory

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

JSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...

Characterizing vineyard‐specific differences in Pinot Noir grape composition in relation to soil properties and rhizosphere microbial communities

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grape berry chemical composition is closely linked to wine quality and provides important information for vineyard management. However, the relationships between berry composition, vineyard soil conditions and rhizosphere microbial communities remain insufficiently understood.
