Abstract: [eng] [cze]
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. Význam dálnic pro šíření organismů je ve střední Evropě široce diskutovaným tématem. Založili jsme tři transkety podél tří hlavních dálnic (D1, D5 a R10) a sledovali jsme závislost výskytu měkkýšů na faktorech geografická poozice, nadmořská výška, vegetační pokryv a stáří komunikace. Překvapivě bylo zaznamenáno 44 druhů, z nichž 21 je v červeném seznamu ohrožených druhů. Dálnice jsou významnou antropogenní stavbou pro šíření nbepůvodních druhů a druhů invazních.
