Vydra riečna (Lutra lutra L.) v antropicky ovplyvnenej krajine - poznatky zo širšieho okolia Lučenca = Eurasian otter (Lutra lutra) in the anthropic affected landscape - experiences from the Lučenec town broad area (Slovakia) / Peter Urban ... [et al.]. -- Systematic research of the Eurasian otter occurrence, changes of their distribution and limiting factors in a broad Lučenec region has been carried out since 1994. Data on the occurrence and some factors of otter in the surrounding of Lučenec town (in a part of the Ipeľ river with tributaries Krivánsky potok, Tuhársky potok, Budínsky potok, Slatinka, Mašková, Velický potok and Mučínsky potok) recorded in 2007-2008 are summarised in this paper. The survey was undertaken by examining special sites (bridges) for otter signs (spraints, smears, tracks). Some environemtantal factors (f. e. bankside vegetation) were observed and identified. The otter occurs along nearly of all of mapping streams. The study of otter distribution was carried out in autumn 2007 and winter 2007/2008 by a modified IUCN Otter Specialist Group method in 6 quadrats (7583, 7584, 7683, 7684, 7783, 7784) of the Slovak Fauna Databank (DFS) grid (11,2 x 12 km). All of the 6 quadrats being positive. In the study area 29 bridges were evaluated and 5 from them were assesed not suitable for safe under-passes for otter.
