Interpreting the environmental record in the sediments of Blelham Tarn [PDF]

open access: yes, 1977
Two aspects of the environmental record in the sediments of Blelham Tarn have been investigated: (1) the ecological history of the catchment, and lake-catchment relationships, by detailed analysis of the preserved pollen (as an indication of vegetation ...

Basophil Activation Test: Bridging Allergy and Oncology for Diagnostic, Therapeutic and Prognostic Applications in AllergoOncology: An EAACI Position Paper

open access: yesAllergy, EarlyView.
ABSTRACT The basophil activation test (BAT) is gaining increasing relevance as an ex vivo functional assay in allergy to evaluate IgE‐mediated hypersensitivity reactions to food allergens, venoms, and drugs and to monitor tolerance induction. Establishing universal standard operating protocols has been difficult, due to several challenges including ...

Multiple indicators record human adaptations to climatic change during the Middle Holocene at the Wanbei site in the middle and lower Huai River valley, China

open access: yesBoreas, EarlyView.
The archaeological sediment sequences analysis from the Wanbei site reveals a predominantly warm and humid climate with a brief cooling phase between 5600 and 5400 a BP, during the Middle Holocene in the middle and lower Huai River valley. Despite the cooling trend, rice remained the dominant crop in mixed farming, while the proportion of millet ...

Luminescence analysis of a postglacial landscape in northeastern Norway and northern Finland

open access: yesBoreas, EarlyView.
Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area. This study uses 186 pOSL measurements and 20 OSL ages to investigate the postglacial landscape evolution inside the Younger Dryas ...

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

open access: yesBoreas, EarlyView.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
