Drivers of population genetic structure are still poorly understood in marine micro-organisms. We exploited the North Sea-Baltic Sea transition for investigating the seascape genetics of a marine diatom, Skeletonema marinoi. Eight polymorphic microsatellite loci were analysed in 354 individuals from ten locations to analyse population structure of the species along a 1500-km-long salinity gradi...

petroleum exploration in north sea during the last decade has become of great importance. an attempt is made to discribe the geological characteristics of this region. informations are given about petroleum and gas reserves of this area until mid 1976. finally a comparision is made between these reserves and those situated in other parts of the world such as the united states , soviet :union:, ...

Sand banks have a wavelength between 1 and 10 km, and they are up to several tens of meters high. Also, sand banks may have an impact on large-scale human activities that take place in the North Sea like sand mining, shipping, offshore wind farms, etc. Therefore, it is important to know where sand banks occur and what their natural behavior is. Here, we use an idealized model to predict the occ...

A long-term time series of plankton and benthic records in the North Sea indicates an increase in decapods and a decline in their prey species that include bivalves and flatfish recruits. Here, we show that in the southern North Sea the proportion of decapods to bivalves doubled following a temperature-driven, abrupt ecosystem shift during the 1980s. Analysis of decapod larvae in the plankton r...

Over the past decade, the distribution of harbour porpoises Phocoena phocoena has undergone a southward shift in the North Sea, which has led to an increase in the number of stranded porpoises in its southern part. Since the changes in distribution and relative abundance of porpoises may be linked to the changes in prey availability, the aim of the present work was to investigate whether any ch...

in this research, for synchronization analysis of black sea high pressure with daily precipitation in iran data base have been created with using the sea level pressure data in reanalysis ii database in national centers for environmental prediction(ncep)/national center for atmospheric research(ncar). temporal resolution of data is daily and spatial resolution is 2.5 㗠2.5 degrees of arc. fram...

Although perfluorinated compounds (PFCs) were used for many applications since the 1950s only in recent years their environmental relevance became apparent. Meanwhile the persistent, bioaccumulative and toxic potential of several PFCs has been proven. A retrospective monitoring was performed to assess concentration trends of PFCs in marine biota from the German Environmental Specimen Bank (ESB)...

North Sea. Holt et al. (2014, reference in the manuscript) found the North Sea less sensitive to production changes and projected less consequences of climate change for the North Sea compared to the global ocean, whereby Gröger et al (2013, reference in the manuscript) found the opposite, a more sensitive North Sea production to climate change. The question of regional consequences of climate ...

Climate warming has forced the distribution of several fish stocks in one of Europe's major fishing grounds many kilometres north or to greater depths to find cooler waters, according to a study by climate change scientists. The distribution of major fish species, including cod and haddock, has shifted in response to an average 1 o C rise in the temperature at the bottom of the North Sea over t...

The mechanisms that determine population structure in highly mobile marine species are poorly understood, but useful towards understanding the evolution of diversity, and essential for effective conservation and management. In this study, we compare putative sperm whale populations located in the Gulf of Mexico, western North Atlantic, Mediterranean Sea and North Sea using mtDNA control region ...
