Comparative analysis of lampenflora in two show caves in Serbia

Nowadays, caves are increasingly being transformed into tourist attractions by constructing paths, electricity, water infrastructure, and the introduction of light, thereby becoming affected various disturbances that alter their inherent equilibrium. Conservation these sensitive environments should be a priority from moment opening. All parameters, including potential changes around artificial lights, such as lampenflora, monitored. Lampenflora in show Serbia has been done for several years Lazar Resava caves, which cave was monitored over 6 years. This work aimed to compare lampenflora two considering samples taken year 2021 at beginning end official season. Artificial light created favorable conditions proliferation phototrophs, developed both caves. Considering community type, epiliths endoliths were present localities. The difference is Cave covered more significant areas substratum, constantly spreading, thus posing threat substratum structures. One problematic genera Chlorella, can switch an autotrophic mixotrophic, finally heterotrophic lifestyle, making dangerous hard deal with. large area while Cave, it usually localized near lights. When compared based on phototrophic microorganism composition, using multivariate analysis, all morphological groups Cyanobacteria (coccoid, simple trichal, heterocystous) related Chlorophyta Bacillariophyta (based diversity number sampling sites they found). In cave, dominated season end. Mosses present, too, with moss protonema characteristic many places. contrast, mosses frequently found reflectors. addition analysis microorganisms, ecological primary production, biofilm parameters measured, showing seasonal or site variations. We hope monitoring will performed regularly future include conservation.
