Analiza ilościowa i jakościowa szczątków fauny ze stanowisk, reprezentujących poziom morski Barbara (V) w przekopach dołowych kopalń Sośnica, Gliwice, Knurów i Pstrowski pozwoliła na dokładną charakterystykę tego poziomu w północno-zachodniej części GZW. Stwierdzono dominujący udział małżów z rodzaju Polidevcia sp. i Anthraconeilo sp. , ślimaków z gatunku Glabrocingulum ostraviensis oraz raminonogów zawiasowych z ewolucją zbiornika morskiego: biofazę nukulową oraz biofazę produktusowo-gonitytową.

Quantitative and qualitative analysy based on fossils in Barbara (V) horizon from mine-galleris in Sośnica, Gliwice, Knurów and Pstrowski coal mines was made. It allowed for detailed characteristics of this level in north-western part of Upper Silesian Coal Basin. Pelecypods, especially Polidevcia sp. and Anthraconeilo sp., gastropods - Glabrocingulum ostraviensis and articulata brachopods are predominating by the number of individuals. Faunal assemblages in Barbara (V) horizon indicate two biophases, connected with basin evolution: biophase of Nucula and biophase of Productids and goniatids.
Analiza taksonomiczno-ilościowa szczątków makrofauny ze stanowisk, stwierdzonych na poziomie 950 m w kopalni Sośnica, pozwoliła na identyfikację tych stanowisk jako reprezentujących morskie poziomy faunistyczne serii paralicznej. W przekopach zidentyfikowano poziomy Barbara, Gabriela, Henryk, Konrad, poziom dodatkowy wiązki Roemer oraz, po raz pierwszy w kopalni, poziom Jarosz. Stwierdzono, że wykształcenie poziomów w badanych stanowiskach nie odbiega od charakterystyki stanowisk, zbadanych na pozostałych poziomach eksploatacyjnych, co świadczy o niewielkiej zmienności warunków środowiskowych podczas utworzenia się poziomów morskich, w obrębie dzisiejszego obszaru górniczego kopalni.

Quantitative and qualitative analyses based on fossils from new localities at 950 m level in Sośnica coal-mine ware made. Which enabled their identification as marine faunal horizons in namurian paralic series. Levels: Barbara, Gabriela, Henryk, Konrad, additional level of the Roemer bunch were identificated in three mine - galleries. For the first time marine horizon Jarosz was recognized in Sośnica coal - mine. The examined marine horizons have a similar formation to those from the localities described earlier in Sośnica coal - mine. This indicates that the environment circumstances during sedimentaton of marine horizons were not very differentiated.

Studies were carried out in the vicinity of Turew near Poznań (Western Poland) in the years 2003 and 2004 in three midfield shelterbelts of different age (150, 11, 6 years old) and along two transects across shelterbelt (6 and 11 years old) >ecotone> field at distance 15 and 50 m from the shelterbelt. The field located in deforested area was treated as the control. The studies were aimed at estimating the changes in community structure (composition, density, biomass) of soil and litter macrofauna, (mainly dipteran larvae), related to shelterbelt age both within shelterbelts as in adjoining fields. The results were compared to previous studies carried out in 1999-2000 in the same agricultural landscape. The density and biomass of soil and litter macrofauna were many times higher in shelterbelts (2824-870 ind. m[^-2] and 3782-521 mg.d.wt. m[^-2]) than in fields (483-53 ind. m[^-2] and 101-12 mg.d.wt. m[^-2]) and increased with the age of planted trees. The same was true for taxonomic richness. Ecotone zone of both transects was characterised by the greatest density and biomass of animals, mainly those of mobile epigeic animals, particularly the ants. The density and biomass values were declining in the field with the increasing distance from the shelterbelt. Across the transect of an older (10-11 years old) shelterbelt and adjacent field the density and biomass of studied animals were higher in all plots than across the younger (5-6 years old) one. It can be concluded, that the effect of the shelterbelt increases with age of planted trees. The results confirm the previous suggestions of the enhancement of the field macrofauna by forested strips. The highest similarity in taxonomic and dominance structure was found between the shelterbelts and their ecotones and they differed significantly from those in the field.
