Direct Evidence of the Geographic Origins of Horse in the Yaoheyuan Site From Ningxia, China

Archaeometry, EarlyView.
ABSTRACT In this study, It is explores the geographic origin of horses by analyzing the strontium isotope ratio of horses from the Yaoheyuan site, an important site in the northwest region of China during the Western Zhou Dynasty. The results show that most of the horses at the Yaoheyuan site were domesticated locally, while a small number came from ...

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Anaerobic Attenuation of Diisopropyl Ether (DIPE) in Groundwater: Kinetics and Implications for Monitored Natural Attenuation

Groundwater Monitoring &Remediation, EarlyView.
Abstract Diisopropyl ether (DIPE) is a branched ether used as a solvent, extractant, and gasoline additive. While aerobic biodegradation of DIPE has been documented, attenuation under anaerobic conditions (typical of groundwater impacted by petroleum hydrocarbons and fuel oxygenates) remains poorly constrained.

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Insights into plant‐part‐specific N2O production in roots and shoots of chicory (Cichorium intybus) using stable isotope labelling

New Phytologist, EarlyView.
Conceptual scheme of the nitrous oxide (N2O) production, consumption, and transport processes across the soil–plant–atmosphere continuum. Summary Nitrous oxide (N2O) contributes substantially to climate change and stratospheric ozone degradation, yet large uncertainties in its global budget point to overlooked sources.
