The Ponto‐Caspian round goby Neogobius melanostomus is a fish well known for its invasion success in North America and Europe. Though it originates from eastern Europe, it is only native to a few rivers in this region. Since the species is physiologically tolerant of varying environmental conditions, rapid spread and establishment to adjacent water basins is likely. Establishment of the species is...
Fish introductions, particularly in areas of high biological diversity and endemism, represent a major threat for biodiversity. In the Balkan Peninsula, 60 fish species have been introduced to date, of which 36 have become naturalized in inland waters. Since the Balkans are one of the world's 35 biodiversity hot spots, this large presence of alien fish species poses a serious threat for the stability...
Ecotourism has been marketed as a form of nature-based tourism, in response to a number of local and regional initiatives associated with marketing nature conservation, local traditions and culture, as alternatives to mass tourism and the need for businesses that can be managed by people without large amounts of money. In this paper we try to apply the principles and methodologies of Knowledge Management...
The study focuses on the phylogenetic origin and genetic diversity of brown trout in the eastern part of the Balkan Peninsula. It further aims to reveal the impact of human-mediated transfers and stocking with non-indigenous trout on the populations in this area. For these purposes, mtDNA control region and microsatellite variation of 204 individuals from 16 populations were analysed. The results...
