A contribution to the moss and liverwort flora of the Reberce Nature Reserve at the Przemyśl Foothills (Western Carpathians, Poland)

Abstract

abStRact. The paper presents the results of studies on bryophyte flora of the Reberce forest reserve located in the Przemyśl foothills. Thirty-three species of liverworts, 70 species and two varieties of mosses were found. Terrestrial (66 species) and epixylic (58) bryophytes formed the largest ecological groups in the reserve. Twenty-four protected species were also recorded, eight endangered bryophytes and six taxa considered as primeval forest species. The most interesting finds are: Bazzania trilobata, Buxbaumia viridis,

Geochemical alkalinity and acidity as preferential site-specific for three lineages liverwort of Aneura pinguis cryptic species A

“…This explanation finds its strict argumentation in the fact that soil-banks are naturally rich in mineral alkaline elements from runoff deposition and hence “minerally" attract bryophytes, A. pinguis species among others, by creating favorable growth and colonisation conditions. Investigations carried out at the Reberce Nature Reserve (Western Carpathians, Poland) 26 , stated among others that 63% of terrestrial epixylic bryophytes, which represented the largest group occurred abundantly in the undergrowth, growing both on rich mineral soil and humus.…”
