| Summary: | The objective of this study was to describe various types of Arctic soil crust that were collected in the vicinity of Petunia Bay, Svalbard in the 2012 summer season. The photosynthetically active area of different soil crust samples was estimated by a chlorophyll fluorescence imaging camera. Biodiversity of cyanobacteria and microalgae from the collected soil crusts was analyzed using a stereomicroscopy and light microscopy. In most cases, cryptogamic crusts were dominated by cyanobacteria such as Gloeocapsa sp., Nostoc sp., Microcoleus sp., Scytonema sp., and Chroococcus sp. The dominant green microalgae were Coccomyxa sp., Hormotila sp., and Trebouxia sp. which commonly occurred in a lichenised soil crust. Soil crusts that were located in conditions with high water content were dominated by Nostoc sp. |
