Comprehensive river basin management mast move beyond narrowly focused programs dealing with water quantity or water quality. A more comprehensive approach to river basin management recognizes that both flow quantity and water quality can be summarized as habitat measures. A number of well developed physical habitat analysis and prediction procedures are presently available. Several computerized systems available from the U.S.Fish and Wildlife Service (Habitat Suitability Index - HSI and PHysical HABitat SIMulation - PHABSIM) provide macrohabitat definition. We have developed a water quality based habitat component which operates effectively for general analysis. With an emphasis on site specific management in the United States, the macrohabitat definition procedures may not meet all river basin management and planning requirements. This paper reviews the results of research which characterizes microhabitat in streams and rivers and provides a valuable extension to basin management procedures.

AbstractRecently confirmed expansion of golden jackals (Canis aureus) into countries without any previous records poses questions, one of them focusing on the species potential and possibly varying habitat use. In this study, we investigated the presence and distribution of golden jackals in northern Bosnia and Herzegovina, where knowledge about golden jackal distribution and habitat use is still scarce. We used bioacoustic stimulation as a non-invasive tool to gather data on golden jackal presence. Habitat structures potentially selected by the species were assessed at 92 calling stations and used as input for binary logistic regression models. Our study area covered approximately 1150 km2, and bioacoustic stimulation within this area resulted in an estimated minimum relative group density of 3.5 territorial groups per 100 km2. We found territorial groups at distances between 15 and 38 km southwards from the river Sava but always within a maximum range of 3 km to perennial watercourses. Habitat analysis identified shrub vegetation and pastures as structures with a significant effect on the presence of resident golden jackals. Probability that golden jackals answered at calling stations increased with increasing surface area covered with pastures and shrubs. Distances between golden jackal territories and the nearest human settlement were relatively small. Our results indicate that structures like transitional woodland-shrubs and pastures, together with other potential influencing factors like local agricultural practices, low hunting pressure, diverse natural and anthropogenic food sources, could have benefited the settlement of golden jackals in the northern lowlands of Bosnia and Herzegovina.

The article discusses issues related to the monitoring of public opinion in pre-project studies on the further development of the Cheremushki district in the city of Odessa. These studies were carried out as part of the international project “Unloved Heritage of a Socialist City?”, in the period from 2016 to 2019. The project was attended by Germany, Ukraine, Russia. The first and second stages of the project were devoted to the study of the German experience in renovation and a research workshop in the city of Odessa. The third stage is the creation of an office to familiarize residents of Cheremushki with pre-project research and monitoring public opinion. The article describes the results of a survey and two discussion round tables on the development and problems of the area; the authors noted the importance of taking into account the results of a sociological survey when conducting pre-design decisions. As a result of the discussion of the first round table, the participants came to the following conclusions: the residents of the region are indifferent to the adjacent territories, believing that these are housing and communal services tasks; their interests end outside their apartments; it is necessary to find methods to activate local residents and involve them in the management of their local territories; the solution may be to create a model quarter on Cheremushki as an example of successful renovation, thereby attracting residents to self-government and the desire to change something; a sociological survey of residents and their acquaintance with research developments on the topic of the development of Cheremushki will favorably affect not only future design decisions, but also the thoughts of residents themselves about the fate of their habitat. Analysis of the survey, the second round table and monitoring the opinions of residents led to the following conclusions: at the moment, investors are not interested in investing in the development of the Cheremushki region; there is no detailed plan for the development of the district at the official level, the city authorities support point and chaotic development; German experience as tracing paper cannot be transferred to Ukrainian realities; the district is inhabited by people of different social levels who have different levels of understanding in the ongoing processes, but most of them favor the preservation of basic architectural and urban planning decisions and the modernization of houses on Cheremushki; there are activists of the region and specialists interested in developing Cheremushki along the path of modernization and comprehensive renovation, using the experience of architectural and urban planning solutions in other countries, for example, Germany, but legal, economic and state support is needed; in conditions of extensive development of the city, it is advisable to use and develop existing territories.
