Luminescence dating of palaeoshoreline deposits from Khyargas Nuur, Western Mongolia: A comparative study of multigrain and single‐grain K‐feldspar dating

Journal of Quaternary Science, EarlyView.
ABSTRACT The evolution of lakes in western Mongolia and their responses to climate changes and glacial meltwater input remain poorly understood. This study evaluates the reliability of multigrain and single‐grain K‐feldspar post‐infrared infrared stimulated luminescence (IRSL) (pIRIR) dating applied to palaeoshoreline sediments at Khyargas Nuur ...

An aminostratigraphy of the northern Upper Rhine Graben, Germany

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

JSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

Contribution of pollinators to delivering fruit quality in commercial sweet cherry orchards

JSFA reports, EarlyView.
Abstract Background Pollinators provide an essential ecosystem service to many crops, including sweet cherry (Prunus avium), which can be quantified in terms of fruit number and/or quality. Most studies in sweet cherry have explored the extent to which fruit set relies on pollinators but have neglected pollinators' contribution to fruit quality.
