MISCELLANEA Tomas 2. ZOOLOGICA 1984 HUNGARICA p. 7—11 Results of complex parasitological investigations on small mammals in the Cergov Mountains (Western Carpathians, Czechoslovakia)* By F. MÉSZÁROS & A. STOLLMANN (Received November 28, 1983) The paper is dedicated to the memory of Tibor WEISZ (1914—1983). ABSTRACT. In the course of parasitological investigations of the small mammals of the Cergov Mts, 104 ecto - and endoparasites were found in 11 species of hosts: Horex araneus

, S. m inn tus

, S. alpinus, Neomys fodiens

, N. anomalus

, Muscardinus avellanarius, Apodemus agrárius, A. flavicollis, Clethriomomys glareolus, Pitymys subterraneus, Microtus arvalis. The parasites were distributed among the following higher taxa: Trematoda 4 species, Cestoda 26 spp„ Nematoda 20 spp,, Acanthocephala 1 sp., Anoplura 4 spp., Siphonaptera 19 spp., Mesostigmata 22 spp., Ixodida 1 sp., Trombidida 7 spp. Research workers from the Institute of Experimental Biology and Ecology of the Slovak Academy of Sciences, Research Station Stare Hory, and the Department of Zoology of the Hungarian Natural History Museum - Michal AMBROS, Alexander DUDICH, Jan KOVACIK, Ferenc MÉSZÁROS, Éva MURAI, Andrej STOLLMANN - carried out ecto- and endoparasitological studies on 382 small mammal specimens belonging to 11 species, collected between August 1980 and April 1982 in the Cergov Mts. Besides this material, some lesser collections have also been analysed, such as fleas from 37 small mammals collected in

4 localities (Circ, Circ-Miníol, Ruská Vol'a, Lenartov) between 1974 and 197 5, and the helminths from 4 small mammal from the vicinity of Krize. The Cergov Mts are part of the Eastern Beskids in the Outern Western Carpathians (Fig. 1). The ridges of the mountains are 900-1050 m a.s.l., the highest point is Minéol, 1157 m. Average temperature in January is -5°C to -7.2°C, in July 13-16°C. The average annual precipitation is 650-800 mm. The basal rocks of the mountains are flysch, marl and sandstone. As to phytogeography, the range belongs to the district "Beskidium Orientale", according to DOSTAL (I960). Prevalent plant communities are Fagetum pauper, Abieto-Fagetum, Abietum and Acereto-Fagetum

. The forested pastures at higher altitudes are a result of human activity (SOFRON, 1975). Eighty percent of the mountains is wooded. The localities (at 550 to 1000 m a.s.l.) are as follows: 1) Hertnik, 2 6-28 Aug. , 1980. Valley of Hertnicky" potok stream, beech forest; 2) Lenartov, 10-12 Nov., 1981 and 20-23 April, 1982. Valley of Vecny

1 potok stream, beech and fire-beech forest; 3) Livov, 20-23 April, 1982. Valley of Vlci potok stream, beech and fire-beech forest, * Report No. 12 from the project "Complex parasitological studies on small mammal populations", a co-operation between the Department of Zoology, Hungarian Natural History Museum, Budapest, and the Institute of Experimental Biology and Ecology, Slovak Academy of Sciences, Research Station Stare Hory.
