Shapovalova I.B. Techniques of Assessment of the Condition of Coastal Ornithological Communities on the Example of Internal Reservoirs of the Dry Steppe Zone in Southern Russia (Republic of Kalmykia) // Arid ecosystems. 2018. V. 24. № 4 (77). P. 58-65. | PDF

The technique of assessment of a condition of coastal ornithological complex is developed, which can be used on any artificial water bodies to detect violations in their work and operation. The article presents the data of some artificial reservoirs of the dry-steppe of the Southern of the European part of Russia (the Republic of Kalmykia). In the course of the work, the main influence factors (water factor) on the water body were identified, and the main indicators of the assessment (number and density) were determined. In the course of the conducted analysis of the coastal ornithocomplexes of the water bodies (dynamics of species diversity, abundance and density of birds in the marsh-near-water complex), their dependence on the water factor (drainage/flooding of a reservoir) was established, which reflections the principle of this technique. In connection with the intensification of anthropogenic impact considered changes of biodiversity of birds of some domestic water reservoirs of Kalmykia, such as Sarpa and Deed-Hulsun, during the period from 2008 to 2015 is considered. The ecological characteristics and the modern assessment of the state of their population in accordance with the developed methodology is given. Recommendations about management of their hydrological mode for the purpose of maintenance and preservation of populations of rare and vulnerable bird species are made.

Keywords: assessment technique, evaluation indicator, influence factor, fluctuation amplitude, look number, look density, abundance, dry-steppe zone, reservoir, aridization, intrazonal landscape, hydrological mode, climate, ornitokompleks, population, marsh and coastal complex.
