Impacts of Biostimulants on Nitrous Oxide Emissions and the Soil Microbiome

Journal of Plant Nutrition and Soil Science, EarlyView.
Soil incubation experiment examining the influence of biostimulants on greenhouse gas emissions and the soil microbiome in fertilized soils. ABSTRACT Background Overapplication of nitrogenous fertilizer and enhanced microbial activity in agricultural soils are drivers of increasing greenhouse gas emissions.

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Igniting Technological and Non‐Technological Innovation for Economic Performance: Enhancing Results by Investing in Human Capital

Strategic Change, EarlyView.
ABSTRACT This study investigates how strategic renewal, driven by the interaction among technological, marketing, and organizational innovation, enhances firms' economic performance. Using a panel dataset of 8871 Spanish firms covering the period 2009–2016, we provide empirical evidence on the different effects of each type of innovation and their ...
