Aquatic animals, such as freshwater turtles, are much dependent on the water bodies where they live. Here we describe the size distribution of a population of Phrynopsgeoffroanus complex that died after the total drought of the artificial water reservoir where it lived in Caatinga. Amongst the 438 animals we found dead in the Cedro water reservoir, we measured the maximum carapace length of 72 individuals. The population was mainly composed of adult individuals and dead turtles measured in areas that kept water for longer were larger than animals from areas that dried up early.

The article considers features of cadastral valuation of agricultural lands occupied by water bodies. The research is based on natural water bodies of the Samara region water fund. A methodology for determining the cadastral value of agricultural lands occupied by artificial water bodies is proposed. The methodology links the land value with the size of the land plot, profit and such objects as dams and other hydraulic structures located within the land plot. The paper confirmed the suggestion that the owner of the land that shall be used for the construction of a pond has the right to the added value of land in the amount of return rate of contributed capital (26.28%). The cadastral value of 1 square meter of agricultural land is 3.11 rubles.

In central Australia, most 1080 (sodium monofluoroacetate) meat baits placed on soil in predator-proof cages remained toxic to dingoes, foxes and feral cats for at least 8 months regardless of whether they were protected from rain or not. Thus, untaken baits will remain a potential hazard to non-target species, particularly farm dogs, for a considerable period. However, when dingo-control programs were monitored (n = 3 stations), approximately 85% of meat baits were taken within 4 days. Dingo-control programs were undertaken on three stations by placing 1080 meat baits near water points (bores) with known dingo activity. Baiting was effective on two stations but not on the third. Where successful, dingo numbers were reduced by 50–70%. The failure on the third station was not due to the lack of bait-take as approximately 80% of these baits were taken within 4 days; it was probably caused by the presence of ephemeral water-bodies that could not be baited. However, this technique was effective in removing those dingoes that utilised the artificial water points, and hence were likely to be interacting with cattle. Such an outcome has benefits to both conservation and the pastoral industry, as problem dogs are removed without placing the long-term survival of dingoes at risk.

A brief review of the ecological state of artificial water bodies is presented on the example of the Voronezh and Matyr reservoirs located in the basin of the river. Voronezh. Ecological-geochemical interrelation of water areas of reservoirs and adjacent territories with anthropogenic sources of pollution located on them is shown. The basis of the research is the bioindication method for the communities of phytoplankton and microphytobenthos. Changes in the sanitary and biological quality of the waters have been studied in the reservoirs, which are related, in particular, to the effect of anomalously high summer air temperatures in 2010–2012 and in subsequent years, and for the Matyr reservoir against this background, an estimate of the effectiveness of the use of algobiotechnology is given.
