Collembola, Protura and Pauropoda in a riparian forest - mesic forest
Rusek, Josef ; Reithofer, D. ; Schmid, S. ; Truxa, Ch. ; Weber, J. ; Wilde, U.
Communities of soil Collembola, Protura and Pauropoda were studied in a riparian forest - mesic forest ecotone in the Stromovka Park in the inundation zone of the Vltava River in České Budějovice, South Bohemia, Czech Republic. Ten soil samples, each 10 cm.sup.2./sup. and 5 cm deep, were taken on April 3rd, 2000 in each of five parallel rows from the swampy part without water (row I). Row II was 1 m to the east from row I in a dense .i.Pragmites communis./i. uderstory of the .i.Populus canadensis, Quercus robus./i. dominated riparian forest. Row III was 5 m to the east with the same understory composition, and IV was 10 m further to the east with less dense .i.Phragmites./i. understory growth mixed with grasses and .i.Geranium silvaticum./i. and other understory herbs and poplar and oak litter on the soil surface. Row V was 5 m from row IV in a mesic forest with .i.Quercus robur, Betula alba./i. trees and grass with mosses in understory.

Nová klasifikace životních forem Collembola a Protura
Rusek, Josef
A new classification of Collembola and Protura life forms is proposed. Each eco-morphological life form group is morphologically and ecologically characterized, allowing Collembola to be classified into two main groups: A - atmobionts, and B - edaphobionts. Group A comprises four subgroups: a) macrophytobionts, b) microphytobionts, c) xylobionts, and d) neustons. Group B is divided into three subgroups: a) epigeonts, b) hemiedaphobionts, and c) euedaphobionts. Hemiedaphobionts comprise two subclasses according to their size and occurrence in the soil profile. Euedaphobionts are divided into three classes (large, medium, small) and six subclasses according to presence or reduction of the furca (with furca versus furca missing or reduced). Protura belong to the medium and small size subclasses of euedaphobionts. Former life form systems of Collembola are discussed. The proposed system facilitates the use of Collembola in a more comprehensive way for ecological studies.

Sukcese hmyzenek (Protura) a vidličnatek (Diplura) na haldách chemické továrny
Rusek, Josef
Primary succession of Protura and Diplura was studied on deposits of a former chemical factory at Petrovice u Karviné, NE Moravia, Czech Republic, in 1978-1979, 1993 and in 2002-2004. Chemically loaded deposits were 15, 25 and 60 years old in 1979 and a primary succession without plant re-cultivation took place there. The succession was delayed on small humps and slopes where the deposited substrate was covered by terrestrial algae, lichens and mosses. Protura did not enter the primary succession before a moss cover occurred on the 15 years old heap and they were represented only by .i.Acerentulus traegardhi./i.. Three species of Protura were established in the 20 years old grass-covered stage as well as on the 49 years old heap. They occurred in low densities up to the 74 years old stage (and older), in which a proturan community of 4-6 species was established.
