Discovery of Late Mississippian (late Serpukhovian)-Early Pennsylvanian (earliest Bashkirian?) foraminiferal assemblages from the Sanandaj-Sirjan Zone, Iran: Biostratigraphic and palaeoenvironmental implications.

This study reports the new discovery of relatively abundant foraminiferal faunas from the upper Serpukhovian-lowermost Bashkirian? of the Ghaleh Formation in the Shahreza region of the Sanandaj-Sirjan Zone, Iran. Four successive assemblages spanning the upper Serpukhovian-lowermost Bashkirian? are proposed: (1) Assemblage with and ; (2) Assemblage with ; (3) Assemblage with and spp., (4) Assemblage with ex gr.

A database of weed plants in the European part of Russia.

Background: Weeds are plants that, although not specially cultivated, grow and often adapt to growing in arable lands. They form an ecological variant of flora, as a historically-formed set of species growing on cultivated soils. For the rational use of the chemical and biological crop protection products and to produce safe and high-quality food, up-to-date data on the floristic diversity of weeds and the patterns of its geographical change are required.
