<i>Tuber mesentericum</i> Vitt. is the only member of black truffles collected in Po|and in the calcareous area at the Częstochowa Upland. It was discovered in 1981 in old beech wood at the Zielona Góra nature reserve (Ławrynowicz 1988, 1990). Recently it has been collected in ca 30 years old oak forest situated 13 km NE from the Częstochowa town. Taxonomic notes, description of habitat and distribution are given.

The Village

The study of the nature reserve oak forest near the village of Pelya-Khovanskaya ecosystem was done in the region of Nizhny Novgorod. The investigated wood is unique for its complex structure. It is situated in the forest-steppe zone, characterized by a high species diversity of small mammals and vegetation, which indicates the complexity of trophic and spatial connections. Several series of sample plots were described: 41 of 2020 m and a number of 11 m sites, totaling 300. Abundance of species by Brown-Blanke scale and the number of specimens of adolescence were specified for each 1 sq. m. plot. Mammals were trapped with the help of trapping grooves and transects method. Vegetation cover is characterized by the presence of a clear intra-differentiation as well as the existence of two basic ecologo-coenotic groups/cores - the nemoral (with Pulmonaria obscura Dum. as the center species of the core) and the meadow-fringe. The most distinct group is formed by forest-shoot species. It can be explained by more forest-steppe rather than nemoral nature of vegetation. Small mammals are represented by the following species: common and small shrews, small forest mouse, yellow-throated and field mice and harvest mouse, vole-housekeeper, common, plowed and red voles, European mole. Two species among them - vole-housekeeper and mouse-baby - are listed in the Red Book of the Nizhny Novgorod Region. Matching burrows of mouse-like rodents with soil richness with nitrogen and humidity, two well-defined peaks are observed. The greatest number of burrows is found in places where the soil is high in nitrogen. Moles were found in areas with a large projective coating of Primula veris: coefficient Spearman rank 0,50. There was a negative correlation of the number of moles and vegetation covering of Pyrethrum corymbosum (-0,46), which is the marker of the driest parts in the forest. In general, the nature reserve oak forest near the village of Pelya-Khovanskaya is of considerable interest, both from botanical and from zoological point of view. Long-term studies of biocoenosis will allow to monitor the facility and to correct the proposed protective measures.

Abstract The paper provides information about 7 species of liverworts and 51 species and 1 variety of mosses collected within the ‘Retno’ Nature Reserve. The diversity of the flora of the reserve is low without any particular bryological values. The most interesting species are Bryum rubens and Orthodicranum tauricum. There are 9 species partially protected in Poland and 1 endangered, however, most of them are common bryophytes throughout the country.

Carabid communities were investigated in a woodland area within the long-term framework of the MAB project in Hungary, in 1985—86 and in 1993—94, using pitfall trapping. The structural characteristics ofthe carabid communitites and the habitat preferences of the most abundant species were studied in a beech wood, an oak forest, a transition zone and an ecotone. Altogether 7,636 carabid individuals were collected, representing 39 species. The value of Shannon diversity and the equitability consistently peaked in the transition zone. Further statistical analysis showed that the studied habitats were remarkably differentiated from each other.

This paper presents data on the occurrence of lichens in xerothermic grasslands, representing a great mycological peculiarity of the NW part of Pomerania, Poland. The 12 examined specimens of six species originated from fieldwork carried out in 2011–2014 in the nature reserves Brodogóry, Stary Przylep, Bielinek, Wrzosowiska Cedyńskie, Prof. Adam Wodziczko Nature Reserve in the Wolin National Park, and an old chalk excavation site on Wolin Island. Within the study sites, four lichen species were recorded as a new to Western Pomerania: <em>Agonimia gelatinosa</em>, <em>Collema cristatum</em>, <em>Dermatocarpon luridum</em>, and <em>Leptogium subtile</em>. The other two species, <em>Collema auriforme</em> and <em>C. flaccidum</em>, are rarely observed in the studied region.

Forest management mimicking natural processes represents an approach to maintain mixed, uneven-aged stands at small spatial scales. The reliance on natural processes, especially on natural regeneration leads to the use of gap-based regeneration as a fundamental silvicultural technique. As a baseline for such management, we investigated mixed forest in unmanaged National Nature Reserve Sitno in the Western Carpathians, which harbours extraordinary diversity on a rather small scale. To quantify the impact of gaps on gap-filling processes and to assess the role they play in recently observed changes in tree species composition we established a large (2.5 ha) permanent research plot and surveyed the status of natural regeneration, forest structure, tree species composition, and disturbance regime. Our research highlights the long-term and contemporary difficulties in the establishment of Quercus petraea (Matt.) Liebl and Fagus sylvatica (L.). Based on the provided evidence, the native tree species diversity in one of the few preserved old-growth multi-species beech-oak forest remnants is not likely to persist, what could have many implications for future ecosystem functioning. Our results suggest that variation in gap size is an important factor contributing to composition of tree species composition of natural regeneration. The recent intermediate-scale disturbance pattern dominating the old-growth beech-oak forest is beneficial to canopy recruitment of species less shade-tolerant than Fagus sylvatica, as Acer pseudoplatanus (L.), Acer platanoides (L.), and Fraxinus excelsior (L.). We discuss possible factors behind observed shifts in tree species composition and limitations for application of gap dynamics to forest practice in managed beech-oak forest systems. Overall, results of this study may help to design silvicultural measures promoting mixed-species forests to deliver a range of desired ecosystem services.

We have researched the population dynamics of Brachyiulus jawlowskii Lohmander, 1928 in the arena of the Dnepr river (within the "Dnieper-Orilsky” Nature Reserve) and also present a full picture of the habitat distribution of Julidae within the researched area. The tested models were basic types of arena biogeocenosis: sand steppe, black maple forests, artificial pine plantations, deciduous forest, meadow and swamp. Variation in population density of B. jawlowskii is determined by biotopical features. The swamp and meadow habitats can be characterized by the highest level of population dynamics. B. jawlowskii plays the greatest role in the herpetobiont grouping in swamp and oak forest habitats (6.7% and 4.6% respectively). In other types of habitat this species composes 0.1–3.5% of the total abundance of this group. The highest abundance dynamic was reached by the Julidae cenopopulations which inhabit the swamp, oak forest and meadow habitats. B. jawlowskii occupies a relatively significant share in the herpetobiont communities of these habitats. Thus, the indicators of absolute number of this species and its relative participation in the herpertobiont grouping indicate the preference of this species for marsh, oak forest and meadow habitats. These habitats can be characterized by an excessive or moderate level of edaphotopic humidification. The ecosystem of the steppe zone of Ukraine is subject to significant human impact. In nature reserves, this effect is minimized, which permits research to be conducted on regimes of natural population dynamics. We established that B. jawlowskii inhabits all habitats investigated within the arena zone of the Dnepr river. This indicates that this is an environmentally flexible Julidae species. The population dynamics of B. jawlowskii can be characterized by three distinct periods: spring-summer, summer and autumn. Each of these periods is characterized by a distinct population dynamic, but throughout the study period the metapopulation of B. jawlowskii remained stable. This is due to the redistribution of representatives of the biotopical metapopulation over a wide range. The conservation regime within the "Dnieper-Orilsky" Nature Reserve had a positively effect on the state of the B. jawlowskii population. Within the reserve on the territory of the arena of the Dnepr river B. jawlowskii uses a wide variety of types of habitats.
