| Description | Bryophytes growing close to lamps in regular use were studied in show caves. Data were collected in 2004 in five caves open to the public: Balcarka Cave, Kateřinská Cave, Javoříčko Caves, Punkva Caves, and Sloup-Šošůvka Caves. All of them are situated in Moravia (the Czech Republic). They are formed in Devonian limestone. The cave environment has an even temperature and high air humidity. Previous investigations of the lamp flora were done in the 1960s–70s. The management of show caves (illumination, chemical removal of plants) has changed since that time. This paper compares the bryophyte lamp flora in the 1960s–70s and the present one. During the previous investigations 51 bryophytes (only mosses) were recorded. In 2004 only 35 mosses were recorded. Overall, 36 % of the bryophyte flora remains the same as in the past. 64 % of the bryophyte flora is different. Amblystegium serpens, Brachythecium velutinum, Fissidens taxifolius and Leptobryum pyriforme were frequently observed both in past and in the present. |
