in this research, the correlation between precipitation change in southern coasts of caspian sea and variability of sea level pressure have been analyzed by using environmental to circulation approach at time period 1339- 1383. in this respect, we make use of daily precipitation data of the 12 synoptic stations of studied area at surface data base section and prepare the time series matrix of p...

There is a strong imbalance in EU transport mode share. In addition issues like road congestion, noise, accident rate and especially pollutant emissions result not only in external costs to society but also in high logistical costs to customers of transport services. The present paper proposes an assessment model to evaluate final internal and external costs of transport chains served by road a...

Investigated sediment cores from the southeastern Black Sea provide a high-resolution record from mid latitudes of the Laschamp geomagnetic polarity excursion. Age constraints are provided by 16 AMS C ages, identification of the Campanian Ignimbrite tephra (39.2870.11 ka), and by detailed tuning of sedimentologic parameters of the Black Sea sediments to the oxygen isotope record from the Greenl...

This information is distributed for the purpose of predissemination peer review. It has not been formally disseminated by NOAA. It does not represent any final agency determination or policy. Introduction Black sea bass (Centropristis striata) are protogynous hermaphrodites, with most individuals maturing first as a female before changing sex to male later in life (Wenner et al 1986). This life...

Article history: Received 5 August 2015 Received in revised form 14 March 2016 Accepted 9 May 2016 Available online 10 May 2016 Dissolved organic carbon (DOC) concentrations in the deep Black Sea are ~2.5 times higher than found in the global ocean. The twomajor external sources of DOC are rivers and the Sea ofMarmara, a transit point forwaters from the Mediterranean Sea. In addition, expansive...

The Ibis T5000 is a novel diagnostic platform that couples PCR and mass spectrometry. In this study, we developed an assay that can identify all known pathogenic Vibrio species and field-tested it using natural water samples from both freshwater lakes and the Georgian coastal zone of the Black Sea. Of the 278 total water samples screened, 9 different Vibrio species were detected, 114 (41%) samp...

The Black Sea is the largest anoxic basin on earth and provides unique conditions for the study of microbial habitats and controls on key anaerobic microbial processes in the element cycles. Recent studies of European research programs carried out in situ measurements of fluxes and turnover of methane and sulfur at seep systems of the Black Sea, and investigated the microbial diversity in perma...

F ontaine et al. provide insight into the structure of a geographically disjunct population on a severe downtrend (1). To understand these data, they turned to a Bayesian statistical approach, providing the mathematical base for changing existing beliefs in light of new evidence. Their hybrid simulation/genomic analysis is one of the latest demonstrations that increasing crossfertilization betw...
