Lampenflora and the entrance biofilm in two show caves: Comparison of microbial community, environmental, and biofilm parameters
(The National Speleological Society, 2020)
Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near artificial light (lampenflora ...
Genus Humidophila from caves in Serbia with an improved detailed description of rare H. brekkaensoides
(Beograd : Institut za bioloska istrazivanja Siniša Stanković, 2020)
Phototrophic microorganisms can be found in biofilms at entrances to caves where they have access to sufficient
sunlight, water and nutrients; however, they can also be found inside caves, where they are carried by animals ...
