the asmari formation at nil anticline area has been studied in order to determine faunal assemblages, the age and the paleoecology. paleontological and biostratigraphical studies led to the identification of 5 faunal assemblages. as a result, the age of the asmari formation in this section, with 291m thickness, is rupelian/chattian-burdigalian. extension of the large benthic foraminifera sugges...

ABSTRACT Functional, physiological traits are the underlying drivers of niche differentiation. A common framework related to niches occupied by terrestrial prokaryotes is based on copiotrophy or oligotrophy, where resource investment primarily in either rapid growth stress tolerance, respectively. quantitative trait-based approach sought relationships between taxa, and prokaryotes. With 175 tax...

Abstract Functional traits can be used to identify various ecosystem processes that are influenced by natural and anthropogenic factors. We tested the hypothesis species composition functional feeding of zooplankton environmental gradients, such as depth, trophic status, ion content. This was in three lignite strip mine lakes Central Poland. Two shallow, polymictic were reclaimed (1994 2008), t...

A novel halophilic bacterium, strain RHS90(T), was isolated from marine sediments from the Gulf of Lions, in the Mediterranean Sea. Its metabolic and physiological characteristics were examined under various cultural conditions, including exposure to stressful ones (oligotrophy, high pressure and high concentrations of metals). Based on phylogenetic analysis of the 16S rRNA gene, the strain was...

The black yeast Exophiala dermatitidis is known as a rare etiologic agent of neurotropic infections in humans, occurring particularly in East and Southeast Asia. In search of its natural habitat, a large sampling was undertaken in temperate as well as in tropical climates. Sampling sites were selected on the basis of the origins of previously isolated strains, and on the basis of physiological ...

For the implementation of the Water Framework Directive we need to develop an informative and cost-effective set of biological monitoring and assessment methods, especially for remote areas. Chironomids are known to be an abundant and speciesrich group that dominate the aquatic macroinvertebrate assemblages in the north and therefore should be an integral part of monitoring and assessment plans...

The deep-water fauna of the Mediterranean is characterized by an absence of distinctive characteristics and by a relative impoverishment. Both are a result of events after the Messinian salinity crisis (Late Miocene). The three main classes of phenomena involved in producing or recording these effects are analysed and discussed: Historical: Sequential faunal changes during the Pliocene and ther...

The geographical location, the shape and the circulation pattern makes the Mediterranean Sea an ideal laboratory to study the interplay between different climatic systems, abrupt climate changes and the response of marine ecosystems. The Ocean Drilling Program Site 963 was drilled in the Northwestern part of the Sicily Channel, the sill that divides the western from the eastern Mediterranean Se...
