Abstract: [eng] [cze]
The micro-distribution of soil mesofauna was studied around a beech stem in a .i.Luzuleto-Fagetum./i. forest in the Voděradské Bučiny National Nature Reserve, ca 30 km east of Prague, Central Bohemia. The soil type was a cambisol on granite. Fifty soil samples (10 cm.sup.2./sup. surface area and 5 cm deep) were taken in five parallel rows at different distances below and above the stem on a gentle SW slope. Soil arthropods were extracted from each sample in a high-gradient extractor. Soil pH and bulk density were determined for each sample after animal extraction. Three .i.Protaphorura./i.-species were recorded in the samples: .i.P. armata, P. pseudovanderdrifti, Protaphorura./i. sp. nov. The eudominant .i.P. armata./i. reached highest density in samples 50 to 100 cm below and above the beech stem where .i.Protaphorura./i. sp. nov. was present only in a low frequency and at most by a single (exceptionally two) specimen per sample. Mikrodistribuce půdní mesofauny byla studována okolo kmene buku v lesním společenstvu .i.Luzuleto-Fagetum./i. v NPR Voděradské bučiny ve středních Čechách. 50 půdních vzorků (10 cm.sup.2./sup. a 5 cm hluboko) bylo odebráno v 7 rovnoběžných liniích na svahu v různé vzdálenosti nad a pod kmenem buku. Ve vzorcích byly zjištěny tři druhy rodu .i.Protaphorura./i.: .i.P. armata, P../i. sp. n. a .i.P. pseudovanderdrifti./i.. Eudominantní .i.P. armata./i. měla nejvyšší abundanci ve vzorcích 50 a 100 cm pod a nad kmenem, v nichž .i.P../i. sp. n. byla zastoupena pouze v nízké frekvenci a nanejvýše v jediném jedinci ve vzorku a .i.P. pseudovanderdrifti./i. se vyskytovala v nízké frekvenci a abundanci pouze ve vzorcích vzdálenějších od kmene. Korelace abundance s biotickými faktory ve vzorcích ukázala, že .i.P. armata./i. dosahovala nejvyšší abundance v blízkosti kmene a .i.P../i. sp.n. se nevyskytovala ve vzorcích s vysokou abundancí .i.P. armata./i..
