The annual flooding in the Amazon basin transforms the understory of floodplain forests into an aquatic environment. However, a great number of non-aquatic bird species occupy the understory and midstory of these forests. In general, these birds are thought to be sedentary and territorial, but the way they adapt to this dramatic seasonal transformation has never been described in detail. In this study, we describe avifaunal strategies to cope with seasonal flooding in the lower Purus region, central Amazonia, Brazil. We conducted focal observations of five insectivorous species occupying the lowest forest strata in two types of floodplain forest (black- and whitewater) during the low- and high-water seasons. For each observation, the height of the bird above the substrate (ground or water), its vertical position in the forest, and vegetation density around the bird were noted. All species remained present in the floodplain forests during the two seasons and were not recorded in adjacent unflooded (terra firme) forest. In general, birds migrated vertically to higher forest strata and most species (three of the five) occupied similar vegetation densities independent of water level. Despite the tendency of all species to rise in relative vertical position at high water, there was a reduction in height above substrate for four of the five species, suggesting that their position relative to water was not an important microhabitat element for them. Responses were similar in the two floodplain forest types. It is likely that the decrease in available space during the flood, combined with similar vertical displacement in arthropods, leads to increased prey density for understory insectivorous birds and permits year-round territoriality without major habitat shifts.

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).

Geobotanical survey of floodplain natural complexes near gypsum outcrops in the Pinega river valley was done in 2015. Large-scale geobotanical map of the key polygon (scale 1 : 30 000) was composed. Typological units of vegetation were selected on the basis of the composition of dominant species and groups of indicator species. Homogeneous and heterogeneous territorial units of vegetation (serial series, combinations, environmental series) were used. 53 mapped unit types (25 homogeneous types and 28 heterogeneous types) were recognized. The floodplain vegetation consists of 17 homogeneous types of plant communities, 3 series, 14 combinations and 6 ecological series. The sites of old floodplain forests, such as willow forests with Urtica sondenii rare in the Arkhangelsk region and oxbow wet meadows with Scolochloa festucacea were identified.
