Transformations of the herpetofauna of South-Western Kyzylkum (Uzbekistan) under the influence of technogenesis

The diversity of herpetofauna in the natural ecosystem southwestern part Kyzylkum has been studied quite deeply. In recent decades, vast desert areas have developed for agricultural crops, and a network irrigation facilities set up watering water supply development new lands socio-cultural objects. However, study animal world, including complex amphibians reptiles under influence anthropogenic factors, overlooked transformed areas. this paper, we present impact consequences man-made factors on Bukhara region, using example hydraulic structures – collectors. studies were carried out along Northern collector at Ramitan Shafirkan stationary points. Seasonal field works from March to May September 2018, October-November 2019, June-August 2020. population density species was determined based permanent selective routes. total, about 80 day-time nighttime observations out, with length more than 130 km. fauna area is represented by two 17 reptiles, three which are listed Red Book Uzbekistan Annex I II CITES one IUCN List. According seasons year, current state population, their habitats, dynamics ratio adults young individuals described. expansion territorial space connection construction collector-drainage system established. Detailed data negative agriculture that verge complete extinction provided. It advisable conduct conservation activities critically endangered regularly.
