BACKGROUND Climate change scenarios that include precipitation shifts and nitrogen (N) deposition are impacting carbon (C) budgets in arid ecosystems. Roots constitute an important part of the C cycle, but it is still unclear which factors control root mass loss and nutrient release in arid lands. METHODOLOGY/PRINCIPAL FINDINGS Litterbags were used to investigate the decomposition rate and nu...
Phylogenetic relationships of Iranian Acanthodactylus species were investigated using 1407 bp of mitochondrial DNA including 606 bp of cytochrome b and 801 bp of NADH dehydrogenase subunit 4 (ND4). Analyses done with maximum parsimony, maximum-likelihood, and Bayesian inference included 67 specimens from 27 geographically distinct localities in Iran. Our molecular results proposed three clear a...
The agricultural transition profoundly changed human societies. We sequenced and analysed the first genome (1.39x) of an early Neolithic woman from Ganj Dareh, in the Zagros Mountains of Iran, a site with early evidence for an economy based on goat herding, ca. 10,000 BP. We show that Western Iran was inhabited by a population genetically most similar to hunter-gatherers from the Caucasus, but ...
The present study investigates the occurrence of wild grasses at Epipalaeolithic and aceramic Neolithic sites in the Near East in order to assess their role in subsistence economies alongside the emergence of cereal cultivation. We use Chogha Golan in the foothills of the central Zagros Mountains (ca. 11.7-9.6 ka cal. BP) as a case study, where the archaeobotanical data suggest the frequent exp...
The emergence of farming during the Neolithic transition, including the domestication of livestock, was a critical point in the evolution of human kind. The goat (Capra hircus) was one of the first domesticated ungulates. In this study, we compared the genetic diversity of domestic goats to that of the modern representatives of their wild ancestor, the bezoar, by analyzing 473 samples collected...
In order to better understand the size distribution of particle-associated PBDEs and their deposition pattern in the human respiratory tract, we carried out a 1-year campaign during 2012–2013 for the measurement of sizeresolved particles at the urban site of Shanghai. The results showed that particulate PBDEs exhibited a bimodal distribution with a mode peak in the accumulation particle size ra...
