Stratigraphy and chronology of a 15ka sequence of multi-sourced silicic tephras in a montane peat bog, eastern North Island, New Zealand. [PDF]

, 1999
We document the stratigraphy, composition, and chronology of a succession of 16 distal, silicic tephra layers interbedded with lateglacial and Holocene peats and muds up to c. 15 000 radiocarbon years (c.

Molecular IgE Reactivity Profiling With Micro‐Arrayed Allergens Reveals Distinct Interregional Patterns of Sensitization and a Hypoallergenic Region in Türkiye

Allergy, EarlyView.
A prospective, systematic and cross‐sectional population study was performed involving 1000 adult subjects from five centers representing different climatic areas of Türkiye (Turkey). Molecular IgE profiling demonstrated substantial interregional variation and identified a hypoallergenic region in the easternmost area with a continental climate.

Arctic Holocene proxy climate database – new approaches to assessing geochronological accuracy and encoding climate variables [PDF]

Climate of the Past, 2014
We present a systematic compilation of previously published Holocene proxy climate records from the Arctic. We identified 170 sites from north of 58° N latitude where proxy time series extend back at least to 6 cal ka (all ages in this article are in ...

Plant Poisons in the Garden: A Human Risk Assessment

Separations, 2022
A study of the plants, and their associated poisons, in the Poison Garden at The Alnwick Garden was undertaken across a calendar year. By selecting 25 plants in the Poison Garden, we have been able to develop a single chromatographic method for the ...

Towards a radiocarbon chronology of the Late-Glacial: Sample selection strategies [PDF]

, 2001
This paper outlines a dating program designed to test the reproducibility of radiocarbon dates on different materials of Late-Glacial age (plant macrofossils, fossil beetle remains, and the "humic" and "humin" chemical fractions of limnic sediments ...

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

Archaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Allergenic pollen seasons and regional pollen calendars for Norway

Aerobiologia
AbstractSeasonal pollen allergy is a major public health concern, with many different pollen aeroallergens being present in the atmosphere at varying levels during the season. In Norway, information about spatiotemporal variation of pollen aeroallergens is currently lacking, leading to reduced ability to manage and treat seasonal allergies.

A POLLEN CALENDAR FOR SIENA (CENTRAL ITALY): PRELIMINARY DATA* [PDF]

New Phytologist, 1982
SUMMARYA preliminary investigation on airborne pollen in Siena was carried out for 1978 using a Burkard trap. For each day pollen grains were counted according to family and expressed in number of grains trapped per m3 of air. The highest concentrations of airborne pollen grains occur in March with the Cupressaceae, Corylaceae, Butulaceae, Salicaceae ...

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

Boreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.

World Allergy Organization Study on Aerobiology for Creating First Pollen and Mold Calendar With Clinical Significance in Islamabad, Pakistan; A Project of World Allergy Organization and Pakistan Allergy, Asthma & Clinical Immunology Centre of Islamabad

World Allergy Organization Journal, 2012
Pollen and mold allergies are highly problematic in Islamabad. This study was conducted to investigate the type and concentration of airborne pollens/molds causing allergic diseases in susceptible individuals. A volumetric spore trap (Burkard) was placed
