Artykuł zajmuje się problemem hibernacji architektury jako formą jej trwania. Przykładem do rozważań na ten temat jest projekt Międzynarodowego Centrum Wystawienniczego w Trypolisie zaprojektowane przez Oscara Niemeyera w 1962 roku w Północnym Libanie. Ten olbrzymi kompleks budynków jest drugim co do wielkości po Brazylii, zrealizowanym przez tego autora i pozostaje w stanie hibernacji od blisko półwiecza. Z jednej strony przetrwał w stanie niezmienionym, pomimo iż na około zmieniło się wszystko, z drugiej strony nigdy nie pełnił roli, jaką mu pierwotnie przeznaczono. Ten stan trwania określamy architekturą w hibernacji.

The paper is dealing with the problem of hibernation in architecture as a form of existents. An example on this topic is a complex of buildings called the International Exhibition Centre in Tripoli designed by Oscar Niemeyer in North Lebanon in 1962. This huge complex, the second largest after Brazil, designed by Oscar Niemeyer remains in hibernation for nearly half a century. This complex, survived in an unchanged form when everything in Lebanon was changed, but on the other hand, never served the role originally assigned to him. This kind of existents we can define as an architecture in state of hibernation.

Numbers of wintering Natterer's bats Myotis nattereri (Kuhl, 1817) and Daubenton's bats M. daubentonii (Kuhl, 1817) were monitored at seven study sites (three single large hibernacula and four groups of roosts) in central Poland. The longest monitoring period was 1987-2009, the shortest - 1999-2009. The aim of the study was to find out if the numbers of the two species are stable, or if any trends could be detected. For most of the study period, bats were counted twice during each hibernation season: in autumn (November/December) and in winter (January/February). The numbers of Natterer's bats show a strong increase all over the study area - a trend similar to that reported earlier from other parts of the country. Daubenton's bats, on the other hand, declined in the hibernacula located in the north-eastern part of the study area, while in those located in the south-western part their numbers were stable or even slightly increased. A decrease in the numbers of Daubenton's bats is in contrast with reports from other hibernacula in Poland and elsewhere in Europe, where the species increases in numbers. The changes in the numbers of both studied species could be explained by neither changes in the hibernacula nor weather conditions during the study period, so our results probably reflect changes in the numbers of local populations.

The aim of our study was to assess the small scale distribution (up to several m[^2]) of hibernating forest-dwelling snails in relation to small-scale environmental factors, like litter composition, soil temperature and humidity or vegetation cover. The study was conducted in the "Dębno nad Wartą" (local name) natural reserve, western Poland, in December 2006. A novel, cartographic method was applied for analysing and illustrating the small-scale distribution and habitat preferences of the snails. Four permanent study plots (15 m[^2]) were established in 50 m intervals. Each plot was divided in fifteen 1m[^2] squares, and from each square a litter sample was taken and analysed (60 samples in total). 17 snail species were recorded (6.13 species per plot; 0.8 per square). The distribution of particular species was clustered as its coefficients of variation were high (CV%> 150) as well as was the small-scale distribution of the total abundance of all the species (CV% = 122). The most uniformly distributed and frequent (C% of all samples) species were Trichia hispida (Linnaeus) (CV%= 153; C% = 45), Cochlodina laminata (Montagu) (206; 30) and Perforatella incarnata (O.F. Muller)(152; 37). Among frequent species the greatest value of CV% (425) and therefore the most patchy distribution was recorded for Ruthenica filograna (Rossmassler). According to the results of CCA, this species, together with Vitrina pellucida (O.F. Muller) (CV% = 296), and Clausilia bidentata (Strom) (CV% = 291), were the most stenotopic, wintering in specific microhabitats with low herb layer coverage, elm leaves prevailing in the litter and high percentages of hornbeam, ash, birch and alder leaves. In turn, for Perforatella rubiginosa (A. Shmidt) (CV% = 440) and Perforatella bidentata (Gmelin)(CV% = 440), also the species with patchy distribution - optimal wintering conditions were found in places with a higher soil temperature and the litter consisting mainly of oak leaves. The remaining snail species seem to be more eurytopic and winter in microhabitats with intermediate conditions. The results of the present study show that for the distribution of majority of species studied the most important factor is the proportion between the coverage of litter and herbaceous vegetation cover. The species richness of the malacocenoses studied strongly depends on the diversity of litter, since particular species prefer leaves of different trees.
