This study examined the cladoceran assemblages in three oxbow lakes of the Taquari River floodplain, near the transition between the plateau and the plain. We sought to answer the following questions: does the Taquari River function as a geographical barrier or dispersal corridor for Cladocera? Can different degrees of connection induce different structures in the assemblages in each lake? Cladocerans and limnological variables were sampled every other month for one year. Forty-one species were recorded, four of which were common to all the lakes. Our results indicated that the different degrees of connection between the river and the oxbow lakes favoured environmental heterogeneity and diversification in the cladoceran assemblages. The greatest dissimilarity between the two lakes connected with the river indicates that in this case the river functions better as a barrier than a dispersal corridor.

Представлены экспериментальные данные о влиянии капельного орошения на урожайность и качество плодов томата при выращивании культуры в открытом грунте Московской области. На плодородных аллювиальных луговых почвах Москворецкой поймы при соблюдении агротехники без орошения в среднем за три года исследований в полевых условиях получена урожайность томата F1 Донской 31,9 т/га, с орошением 48,5 т/га, в т.ч. стандартной продукции 42,6 т/га.The article presents experimental data on the effect of drip irrigation on the yield and quality of tomato fruits when growing crops in open ground of the Moscow Region. On fertile alluvial meadow soils of the Moscow river floodplain, with the observance of agricultural technology without irrigation, the field yield of tomato hybrid F1 Donskoi on average for three years of research was 31.9 t/ha, with irrigation 48.5 t/ha, incl. standard production 42.6 t/ha.

The paper characterizes poplar (Populus alba, P. nig­ra) and white willow (Salix alba) forests of the Irtysh and the Black Irtysh river floodplain, together with the silvery salt tree (Halimodendron halodendron) community of the Black Irtysh river floodplain. The Black Irtysh floodplain willow and poplar forests are separated into a new alliance, Rubio dolichophyllae—Populion albae Taran all. nov. (Salicetalia purpureae Moor 1958, Salicetea purpureae Moor 1958), which includes the associations Rubio dolichophyllae—Popu­letum albae Taran 1997 and Rubio dolichophyllae—Salicetum albae Taran ass. nov. The Halimodendron halodendron community is probably related to the class Nerio-Tamaricetea Br.-Bl. et de Bolós 1958. White poplar forests in the Irtysh R. upper reaches, described within the Semipalatinsk city limits, belong to the association Heracleo dissecti—Populetum albae Taran 1997 and its subassociation H. d. —P. a. lamietosum albi Taran 1997 (Equiseto hyemalis—Populion nigrae Taran 1997, Salicetalia purpureae Moor 1958).

In the Ob river floodplain between the mouths of its tributaries Vakh and Tym (within the limits of Aleksandrovskiy district of Tomsk region), phytocoenoses belonging to 9 associations and 2 communities of Braun-Blanquet classification vegetation classes are listed. Class Lemnetea is represented by associations Ricciocarpetum natantis (Segal 1963) Tx. 1974, Lemnetum trisulcae Soó 1927, Stratiotetum aloidis Miljan 1933; class Potametea is done by asso­ciations Potametum perfoliati Koch 1926, Myriophylletum sibirici Taran 1998, Myriophylletum verticillati Soó 1927, Potametum graminei Koch 1926, Potametum pectinati Carstensen 1955, Nymphoidetum peltatae (All. 1922) Bellot 1951, as well as Sagittaria natans and Potamogeton natans—Ceratophyllum demersum communities. The syntaxa distribution in Western Siberia and adjoining territories is characterized.
