Response of soil mites (Acari, Mesostigmata) to long-term Norway spruce plantation along a mountain stream.

During the nineteenth and twentieth centuries, coniferous monocultures were introduced, replacing natural broadleaved forests in Central Europe, mainly for economic benefits. In the mountains, Norway spruce [Picea abies (L.) H.

Natural forest remnants as refugia for bryophyte diversity in a transformed mountain river valley landscape.

Riparian forests are among the most threatened ecosystem types worldwide. Their exploitation and replacement by coniferous plantations affects species pools and contributes to loss of biodiversity. We aimed to investigate bryophyte species pools within different habitat types in a transformed mountain river valley.

Abiotic determinants of the historical buildings biodeterioration in the former Auschwitz II-Birkenau concentration and extermination camp.

The paper presents the results of a study conducted at the Auschwitz-Birkenau State Museum in Oświęcim on the occurrence of biodeterioration. Visual assessment of the buildings revealed signs of deterioration of the buildings in the form of dampness, bulging and crumbling plaster, and wood fiber splitting. The external surfaces, and especially the concrete strips and ground immediately adjoining the buildings, were colonized by bryophytes, lichens, and algae.

Assessment of biological colonization of historic buildings in the former Auschwitz II-Birkenau concentration camp.

The objective of this study was to assess biological colonization of wooden and brick buildings in the former Auschwitz II-Birkenau concentration camp, and to identify the organisms colonizing the examined buildings. Microbiological analysis did not reveal increased microbial activity, and the total microbial count of the barrack surfaces did not exceed 10 CFU/100 cm. However, certain symptoms of biodegradation of the buildings were observed.
