Opis:
During the Devonian the sedimentation on the continental shelves of Ardenne Massif and Boulonnais has changed from a mixed siliciclastic-carbonate ramp (Eifelian), through a carbonate barrier reef (Givetian) and then to a detritic influx with local mud-mounds (Frasnian). Here we analysed the faunistic dynamics of the trilobite associations through the changing environment. We used multivariate analyses (clustering and ordering) to discriminate the trilobite associations within 67 different samples. Three previously known communities and one new were recognised: the Eifelian Mixed association, the Givetian Dechenella association and the two Frasnian Bradocryphaeus and Scutellum-Goldius associations. These trilobite faunas present a progressive ecological specialisation. The Mixed association occurs both in the ramp or carbonated (local reef developed on the ramp) facies without any significant difference in its composition. The Dechenella fauna occurs preferentially close to barrier reefs, but can also survive during short periods of detrital input. The two Frasnian communities show a strong relationship with their environment. The Scutellum-Goldius association is only found in reef systems, whereas the Bradocryphaeus flourishes exclusively in lateral facies.

Opis:
The paper deals with succession in an abandoned quarry of crystalline limestone, located in the village of Rogóżka (Krowiarki Mts near Konradów, the northern extension of the Śnieżnik Massif). Its bottom is covered by synanthropic communities of unspecified systematic rank and communities of limestone screes as well as clumps of Alnus incana and Betula sp. The following communities, gradually entering the quarry, have been distinguished: Dentario-Fagetum, Aceri-Tilietum and Carici remotae-Fraxinetum. The malacofauna collected in the quarry (45 species) constitutes 50.6% of the terrestrial snails recorded from the OEnieżnik Massif (89 species) and 43.7% of those collected in the Kłodzko Region (103 species). Seven of the 15 clausiliid species recorded from the Kłodzko Region were found in the quarry (47%), which indicates considerable diversity of the microhabitats. The most important species include Eucobresia diaphana, Semilimax semilimax, Macrogastra tumida, Helicigona lapicida, and most of all Clausilia parvula; for the last species the quarry in Rogóżka is the only extant locality in the Kłodzko Region. The fate of the quarry’s malacofauna is uncertain, since formally it has not been exluded from exploitation; measures need be taken to establish a nature reserve there.

Opis:
Previously, it was believed that there was a dramatic turn−over in the fauna of beavers (Rodentia, Castoridae) from the Barstovian to the Clarendonian from Nebraska. Stratigraphically controlled collections of fossil castorids from the Valentine Formation, which cross this boundary, now indicate that a complete change in the castorid fauna did not occur, but instead a more gradual change and replacement of earlier taxa with more advanced taxa occurred. The range of Eucastor tortus and Monosaulax skinneri is extended from late Barstovian into the latest Barstovian Devil’s Gulch Member and the range of the otherwise Clarendonian species of Prodipoides is extended downward into the late Barstovian Crookston Bridge Member. The skulls of Monosaulax skinneri and Eucastor valentinensis are described in detail for the first time. The cranial morphology of M. skinneri is primitive for Castoroidini and that of E. valentinensis is specialized for tooth−digging behavior as in the Nothodipoidini. A new genus, Temperocastor, is proposed for E. valentinensis based on its primitive morphology of the cheek teeth and derived cranial morphology. Temperocastor represents the most primitive nothodipoidine.

Opis:
The paper presents the results of a three−year research on ground beetle (Carabidae) assemblages conducted in the stands of the Piska Primeval Forest damaged by the 2002 hurricane and in control stands. Observations were carried out in the stands categorised into 5 age classes: class I (20−40 years), class II (40−50 years), class III (50−60 years), class IV (60−70 years) and class V (over 70 years). Beetles were caught using modified Barber's traps. The soil CO2 efflux rate and C:N ratio were measured. The Ward cluster analysis and Canonical Correspondence Analysis (CCA) clearly distinguished between carabid assemblages in the stands damaged by the hurricane and control stands. In damaged stands there was an increase in the number of Carabidae species with the simultaneous decrease in their abundance. The proportion of forest and European species has been considerably reduced. A marked decline in abundance of hygrophilous species in favour of xerophylous ones was also noted. The observed reduction in the SPC (Sum of Progressive Characteristics) index may indicate the preservation of changes in carabid assemblages and that their regeneration has not yet started.

Opis:
Exceedingly violent winds can result in windbreak and in windthrow. It has happened in summer of 2002 in Pisz Forest District (north part of Poland). Strong wind damaged about 30 000 hectares of pine forest. In most situations, damaging wind resulted in windthrow rather than windbreak. In total 30 plots were selected for the studies, 15 plots in Pisz forest (damaged by wind) and 15 control plots in Maskulińskie District Forest (not damaged by wind). There were distinguished 5 age variants of stands, all of them in three recapitulations. The five age classes of stands were: I class (20−30 years old), II class (30−40 y.), III class (40−50 y.), IV class (50−70 y.) and V class (above 70 years old). In total 4 000 carabids individuals belonging to 46 species were caught during studies. The wards analy− sis showed substantial diference of carabid assemblages occurring in damaged and non damaged forest. In damaged forest, small zoophages, hemizoophages, an open area or eurtyopic species, xerophilus species were frequently observed. Substantial differences in mean individual biomass of assemblages occurring in damaged and non damaged forest were also observed.

Opis:
Investigations were carried out in 2000−2001 on the succession of carabid assemblages accompanying the spontaneous succession of pine stands on former agricultural land. Observations concerning changes in the number of carabid individuals and species, proportion of individuals in the groups: developmental, ecological, trophic, geographical, moisture preference, wing differences, as well as the mean individual biomass (MIB) indicated that the development of carabid assemblages during the spontaneous succession of stands can be compared to the regeneration process of the carabid fauna that accompany afforestation and that the direction of this development is similar to the development of carabid assemblages that accompany afforestation of farmlands.
