The paper presents a brief review of published so far and recently recorded unpublished bryological data concerning the distribution in Poland of two neophytic (sensu Meusel 1943) mosses: Campylopus introflexus (Hedw.) Brid. and Orthodontium lineare Schwaegr.to estimate their current influence on native bryoflora. The data clearly indicate the constant spreading of these species towards the east, however, there is no direct evidence that they have been limiting the occurrence of native moss species. They are acidophilous species, so the acidification of the environment probably promotes their expansion. Maps of the most current distribution of Campylopus introflexus and Orthodontium lineare in Poland (in a system of ATMOS-grid squares) are provided, as well as a description of the first locality in Poland of another European bryo-neophyte species Leptophascum leptophyllum Mull.

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,
The results of bryological investigations from the "Boczki" nature reserve, located in Puszcza Romincka Forest, are presented. The reserve was established in 1974 for protection well preserved forest communities characteristic of the Romincka Primeval Forest. 154 bryophyte species were recorded -37 liverworts and 117 mosses, including 37 unpublished species from the Puszcza Romincka Forest. In respect of frequency the main group make rare species -29.2%, the least numerous were frequent -21.4%. Terrestrial and epixylic habitats were the richest -refer 98 and 85 species respectively. Significant were groups of protected (47) and endangered ( 14) species. There is also a large share of bryophytes considered as primeval forest species -seven liverworts and 24 mosses, Antitrichia curtipendula and Zygodon rupestris among them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
