  1. Artikel ; Online: An Updated Distribution of the Herpetofauna from the Natura 2000 Site Rarău-Giumalău (Rosci0212), Romania

    Abstract Amphibians and reptiles are among the most threatened animal species in Europe. Because of their legal conservation status, amphibians and reptiles may act as umbrella and flagship species in certain areas. The Rarău-Giumalău Natura 2000 site (ROSCI 0212) is such an area that, despite its conservation status, is still exposed to human activities alterations. In addition, the standard data form of the site mentions only three amphibian species, which is notably below the herpetofauna diversity of the region. Therefore, the aim of this study is to update the existing knowledge on the local herpetofauna. To this end, herpetological field surveys were conducted in the area between May– September, 2015, ten species being identified, as follows: six amphibians (Salamandra salamandra, Lissotriton montandoni, Ichthyosaura alpestris, Bombina variegata, Bufo bufo and Rana temporaria) and four reptiles (Anguis colchica, Lacerta agilis, Zootoca vivipara and Vipera berus). Species distribution is influenced by human activities, among which grazing seems to be the most important. The diversity of herpetofauna is not evenly distributed between the perimeters of the site. The Giumalău perimeter has only six species probably because of a lower habitat diversity compared to the Rarău perimeter. Nine of the identified species are protected by European and national regulations, whereas the standard data form of the site lists only two of them, and one not confirmed by our study. Therefore, the standard data form, a tool for protective management, does not reflect the real situation of the herpetofauna of the site and for this reason, it should be updated.

    Abstract The observations concerning the acoustic behaviour and the recordings of the songs of the Great Reed Warbler (Acrocephalus arundinaceus) were made during the reproduction periods, from April to July, in 2003 and 2004. During the reproduction period, while singing, the Great Reed Warbler shows a characteristic posture: he cleans his plumage with the peak; the plumage is slightly ruffled; the tail is spread; the head is orientated towards the lake or reed beds where it intends to establish a territory. Every time when the Great Reed Warbler sings, it chooses a high place for revealing his vocal repertoire. The Great Reed Warbler’s song shows a considerable variedstructure. In the studied area, the songs comprise six different types of units. The average song duration is 3.57± 0.10 s. The average number of units per song is 12.29± 0.96, whereas the average number of distinct units per song is 3.75± 0.81. There is a positive correlation between the song duration and the number of units per song. The highest amplitudes of the songs of the Great Reed Warbler from the studied area correspond to frequencies smaller than 3kHz.
