Společenstva měkkýšů podél dálnic ve vazbě na proměnné prostředí
Juřičková, L. ; Kučera, Tomáš
Motorways are one of the widespread and frequently discussed landscape features, especially in Central Europe. We established three transects along the three main motorways in southeastern, southwestern, and northern directions from Prague (D1, D5, R10). These transects covered major environmental gradients of geographical position, altitude, succession, and vegetation cover. Altogether 44 land snail species (more than 26 % of the Czech Republic’s land snail fauna) were found at the 45 sites on the verges along 225 km of motorways. Surprisingly 21 % of species were such included in the Red List of the Czech Republic’s molluscs, and the endangered species Daudebardia brevipes was even present by a very abundant population. We expected the motorways to be of importance as man-made linear structure for the spreading of invasive and synathropic species, but only one such species has been found - Monacha cartusiana.
