SummaryThe Houbara Bustard Chlamydotis undulata macqueenii is a regular winter visitor from northern breeding grounds to the United Arab Emirates (UAE) but the migration routes and origin of these birds are still poorly known. Five bustards were fitted with platform transponder terminals in UAE in the winter of 1996-1997. The overall distances covered by the birds were very variable, ranging from 3,747 km to 11,938 km. The return migration date of Houbara from UAE ranged from 19 March to 2 April 1997, while the outward migration began from 10 September to 7 November 1997. The Houbara spent the summer n i different areas, namely China (north of lake Nor), Kazakhstan (Kyzyl Kum desert and north of the Aral Sea), Uzbekistan (south of the Aral Sea) and north Afghanistan. These results are the first to describe an annual cycle of migration for Houbara Bustards and should aid the development of appropriate conservation measures for this species.

In last years, in floristic investigations, more attention has been paid to the formation of the electronic databases. In Uzbekistan, this tendency is associated with the research of K.Sh. Tojibayev (Database, 2010), where a database of large natural flora was compiled for the first time in Central Asia. In subsequent years, the accumulation of floristic data in the form of an electronic database has become one of the mandatory components. In particular, special attention was paid to this in the work of F.I. Karimov on monocotyledonous geophytes of the Ferghana Valley (Karimov, 2015)

The article is devoted to the study of the growth and development of Salsola orientalis S. Gmel in a culture. In the literature, the growth and development of Salsola orientalis S. Gmel is readily eaten by animals in all seasons and is a good fatty food for sheep. The eaten part of the plants is annual shoots with leaves; flowers and fruits, often more lignified lower parts of the bushes. Therefore, it is difficult to find plants in grazed areas that are not damaged by animals, which makes Salsola orientalis quite suitable for making hay. Despite the practical value of this species and great attention from researchers, the growth and development of Salsola orientalis, taking into account the influence of the ecological conditions of the Karakalpak part of the Kyzyl-Kum Desert, have been little studied.

Survey of the aquatic subterranean fauna from caves, springs, interstitial habitat, wells in deserts, artificial tunnels (Khanas) of five countries of the former URSS (Kazakhstan, Kyrgyzstan, Tadjikistan, Turkmenistan, Uzbekistan) located far east the Caspian Sea. The cave fauna present some originalities: - the rich fauna of foraminiferida in the wells of the Kara-Kum desert (Turkmenistan); - the cave fish Paracobitis starostini from the Provull gypsum Cave (Turkmenistan); - the presence of a rich stygobitic fauna in the wells of the Kyzyl-Kum desert (Uzbekistan); - the rich stygobitic fauna  from  the hyporheic of streams and  wells around the tectonic Issyk-Kul Lake (Kyrgyzstan); - the eastern limit of the European genus Niphargus from the sub-lacustrin springs  on the eastern shore of the Caspian Sea (Kazakhstan); - the presence of cave fauna of marine origin. Approximately 96 stygobionts, 9 stygobionts/stygophiles and 3 troglobionts are recorded.
