Methods for remote sensing of the underlying surface in microwave range based on moisture dependence soil emissivity were successfully used monitoring droughts and assessing water availability studied territories. Soil influence cover calibrated units radio brightness temperature (TB) was studied. We values TB derived from SMOS satellite data. This paper presents results a comparative analysis ...

Aims : The vegetation classification system of China (China-VCS) is not completed. Stipa steppes are the most important in China. Here we made optimal use available plot data to classify into associations a way that consistent with International Vegetation Classification. Study Area: Songnen Plain, Inner Mongolian Plateau, Loess Tibetan and northwest mountain areas Methods: We used 1337 plots p...

Une dédicace à Neptune découverte en 1963 Feriana, l’antique Thelepte Afrique proconsulaire, est restée longtemps marge des études sur l’Afrique antique. Succinctement signalé et publié plusieurs reprises, ce texte très court l’unique document de type provenant site fort important mais peu fouillé. Il atteste également un nom rare, Magaricus, qui n’était jusque-là attesté qu’à Sicca Veneria sou...

Biological Soil Crusts (BSCs), consisting of prokaryotes, microalgae, lichens, mosses and eventually small vascular plants, cover wide areas in arid and semi-arid environments. In the present study, the microbial diversity of these crusts was explored at extrazonal mountain steppe sites in the western Khentej (Northern Mongolia). At the study site the Siberian taiga borders on the Mongolian-Dau...
