Seasonal development and vertical distribution of soil rotifer populations in South-Bohemian beech forest
Devetter, Miloslav
The soil rotifer community in a climax beech forest in South Bohemia was investigated during 2005 focusing on seasonal and vertical distribution changes. Samples 10 cm.sup.2./sup. large and 10 cm in depth were divided into 5 layers, which were processed separately. Altogether 31 rotifer species were determined during the investigation, of these 9 species were monogononts, while the rest were bdelloids. The most important species were .i.Encentrum arvicola, Wierzejskiella vagneri./i. among the monogononts and .i.Adineta steineri, Ceratotrocha cornigera, Habrotrocha filum, H. ligula, Macrotrachela plicata, Mniobia tentans, M. incrassata, M. granulosa./i. among the bdelloids. Mean Shannon diversity index varied from 1.99 to 2.63. Total rotifer abundance varied from 212 (± 63) to 513 (± 127) 10.sup.3./sup. ind. m.sup.-2./sup. year-round, with the highest numbers found in May, while the lowest were in July.
