Endemics and relicts in the high- fauna of

Petar Beron

Abstract: The orophyte zone in Bulgarian is about 1.37% of Bulgarian territory in eight mountains higher than 2000 m). and are the only mountains higher than 2400 m and most of the relicts and endemics are centered in these mountains.

Key words: Endemics, relicts, high-mountain fauna, Bulgaria

Реликти и ендемити във високопланинската фауна на България

Петър Берон

(Резюме) Разглежданата тук област (над 1900 м) обхваща около 1.37% от българската територия в осем планини, от които Рила и Пирин надхвърлят 2400 м. Там са съсредоточени и повечето ендемични и реликтни видове животни (изброени по-горе). Има както тесни локални ендемити, така и балкански такива. Осоено добре са застъпени групите Araneae, Acari, Orthoptera, Coleoptera, Heteroptera, Lepidoptera.
