Abstract Species diversity and frequency index of bivalve mollusks’ of unionid family are researched within river basins of Ukraine. The largest frequency index of mussels is identified in the Prypiat and Desna basins (84 and 79% respectively), then (as the indicator declines) – the Dnieper and Severskiy Donets basins (74 and 67%), the Southern Bug and Danube (47 and 46%), the Southern and Western Bug (47 and 28%), the Crimea (17%). No mollusks were found in the Azov basin at all. Most often (33%) there were found groups consisting of only three unpretentious species (Unio pictorum, U. tumidus, Anodonta anatina). In general, settlements from one to three species make up 70% of all researched collecting sites. Settlements formed by four species are identified only in 23% of habitats. Only 6% of settlements consisted of five aboriginal species and about 1% – of six. Locations where six species lived together were identified only in the Danube and Prypiat basins. There are no settlements of five species in the Western Bug and Desna basins at all, and there are not any even four species settlements in the Crimea. The obtained data can be used for organizing environmental activities and assessing water environment quality

In contrast to the hydrological and hydrochemical zoning, hydrographic and water management zoning of Ukraine (2016) was created on a basin basis, taking into account the boundaries of river basins, and not physiographic zoning. The main function of hydrographic and water management zoning is water management. Primary is hydrographic zoning, and water management - based on it. The description of modern hydrographic zoning of the territory of Ukraine, approved in 2016 by the Verkhovna Rada of Ukraine and included in the Water Code of Ukraine is given. Hydrographic zoning is carried out for the development and implementation of river basin management plans. On the territory of Ukraine nine areas of river basins are allocated: Dnipro; Dnister; Danube; Southern Bug; Don; Vistula; rivers of the Crimea; rivers of the Black Sea coast; rivers of the Azov Sea coast 13 sub-basins are allocated in four river basins district. The water management zoning is described - the division of hydrographic units into water management areas, which is carried out for the development of water management balances. In the regions of the river basins in the territory of Ukraine allocated 132 water management areas, 59 of which are located in the Dnipro basin. About 9,000 bodies of surface water allocated for monitoring in Ukraine. Approved zoning is the implementation of the provisions of the EU Water Framework Directive 2000/60 / EC in the management of water resources in Ukraine. Modern hydrographic and water management zoning of the territory of Ukraine approximates the management of water resources of the state to European requirements.

Ecological Remediation

Due to the recent excessive pursuit of rapid economic development in China, the cultural heritage resources have been gradually destroyed. This paper proposes cultural recovery and ecological remediation patterns, and adopts virtual reality (VR) technology to evaluate the visual aesthetic effect of the restored landscape. The results show that: (1) the average vegetation coverage increased, providing data support for remediation design evaluation; and (2) the fixation counts and average saccade counts of the subjects increased after the remediation design, indicating that the restored cultural landscape reduced visual fatigue and provided a better visual aesthetic experience. Furthermore, the comparative analysis of the quality of the water environment shows that the remediation design project improved the ecological environment quality of the relics area. The results of this study will contribute to rural revitalization in minority areas in southwest China.

The current status of the global organic viticulture is discussed. The challenge of conservation of species and landscape biodiversity in the Crimea is actualized. The fauna of mites and other insects in the grape agrocenosis of the South Coast of the Peninsula is reported. Biodiversity of mites and other insects in commercial vineyards at different pesticide loads is shown. The role that wild-growing vegetation in territories adjacent to vineyards plays in the agrolandscape of grape agrocenoses is highlighted. The commonness of species diversity of predatory mites in a vineyard and on its outskirts is revealed. The possibility to rely on natural mechanisms for self-regulation of population numbers of phytophagous mites under conditions of organic viticulture is demonstrated.

Patterns of amplified DNA fragments flanked by (GGAC)n microsatellites, obtained by single primer amplification reaction (SPAR), from 198 Gymnotus specimens (Pisces: Gymnotiformes) sampled from 8 southeastern Brazilian river basins were analyzed. The species studied were Gymnotus carapo, G. pantherinus, G. inaequilabiatus, and G. sylvius. The indirectly obtained patterns reflected the distribution of simple sequence repeats in the nuclear genome of the specimens. Species-specific patterns of DNA amplification were found and were useful for the analysis of the geographic distribution of Gymnotus species. Monomorphic patterns were found in G. carapo, G. pantherinus, and G. inaequilabiatus. Three polymorphic patterns were found in G. sylvius populations. The SPAR technique could be a useful molecular tool in conservation programs involving communities of neotropical freshwater fish.
