Tin–Lead Sewn Tokens From 13th‐Century Gdańsk: Assessing Local and Non‐Local Production Through Archaeometric Analysis

Archaeometry, EarlyView.
ABSTRACT This study presents the results of an interdisciplinary investigation of 98 tin–lead sewn tokens from 13th‐century Gdańsk, the largest assemblage of its kind in Central Europe. Combining archaeological context, typology, SEM‐EDS and lead isotope analysis, the research explores provenance, production and function.

Manure, Soil Organic Matter and Fertility

Bulgarian Journal of Soil Science, 2016
Higher content of soil organic matter can greatly reduce the difficulties of a good crop production system. Content of organic matter in the majority of Bulgarian soils is very low which is evident from the results of soil survey and the data from mass chemical soil tests – nearly 60% of studied soils are with humus content lower than 2.5%. The organic

Wet Season Carbon (δ13C) and Nitrogen (δ15N) Composition of Modern Plants as Isotopic Framework for Agropastoral and Palaeoecological Studies in Northern Greece

Archaeometry, EarlyView.
ABSTRACT Mediterranean wetlands are one of Europe's most vital and endangered biodiversity hotspots. This study determined the carbon (δ13C) and nitrogen (δ15N) isotope values of modern plants to construct an isotopic framework by which to contextualize agropastoral management in and around past wetland ecosystems.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, EarlyView.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...
