‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Linking debris flows and landslides to large floods in Gravel-Bed Rivers

, 2015
Landslides and debris flows are very effective geomorphic agents influencing the evolution of fluvial systems in mountain catchments. The concurrence of landslides, debris flows and floods urges the development of methods that can cope with multiple ...

Revealing New Aspects of Digital Transformation: The Effects of Digital Transformation on Work Engagement and Proactive Behavior

Strategic Change, EarlyView.
ABSTRACT This study explores the direct and indirect effects of digital transformation (DT) promotion and digital transformational leadership (DTL) on work engagement (WE) and proactive behavior (PB). For many firms, DT requires a change from existing business strategies.

Influence of the growing area on cone yield and alpha and beta acid content in Cascade hops: An Italian case study

JSFA reports, EarlyView.
Abstract Background Territorial food production is a well‐known quality trait, which is attracting new customer preferences for different agricultural products. In this context, many microbreweries and agricultural breweries started to cultivate their own small hopyard to exploit the so‐called “terroir” effect.

Sedimentation characteristics of gravel in discharge pipe of slurry shield tunneling and its impact on slurry

Yantu gongcheng xuebao
The slurry shield tunneling in weathered rock layers is prone to gravel accumulation within the slurry pipe. In order to study the transportation characteristics of gravel in the slurry pipe, a model of gravel transportation in the slurry pipe of the ...

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.

Asynchronous Response of Plant Productivity and Soil Aggregate Nutrients to Grazing Exclusion Duration in Alpine Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grazing exclusion is a critical restoration measure for degraded alpine steppe ecosystems. However, research remains limited on the key factors influencing soil aggregates that affect plant productivity and the mechanisms influencing nutrient distribution across aggregates of different size fractions during long‐term grazing exclusion.

Long‐Term Operation of Photovoltaic Power Stations Promotes Soil Carbon Sequestration but Induces Stoichiometric C:N:P Imbalance in Desert Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Soil carbon‐nitrogen‐phosphorus (C:N:P) stoichiometry governs nutrient cycling and carbon sequestration in desert ecosystems, yet how large‐scale photovoltaic (PV) deployment, a cornerstone of global carbon neutrality, shifts these stoichiometric balances and whether such shifts enhance or degrade long‐term land function remain unresolved over
