Abstract

The paper presents a brief review of published so far and recently recorded unpublished bryological data concerning the distribution in Poland of two neophytic (sensu Meusel 1943) mosses: Campylopus introflexus (Hedw.)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. Hal.

Highlights

Nowadays biological invasions are considered to be one of the main topics in the fields of ecology, phytogeography and taxonomy
The aim of study was to analyze the current spreading of neophytic bryophytes in Poland and to attempt to estimate their influence on native bryoflora
First observations of these species in Europe came from Britain: Orthodontium lineare was recorded for the first time in 1911 close to Manchester, Campylopus introflexus in 1941 in Sussex, Leptophascum leptophyllum in 1965 (Frahm 2002)

Summary

INTRODUCTION

Nowadays biological invasions are considered to be one of the main topics in the fields of ecology, phytogeography and taxonomy. First observations of these species in Europe came from Britain: Orthodontium lineare was recorded for the first time in 1911 close to Manchester, Campylopus introflexus in 1941 in Sussex (after Ochyra 1983), Leptophascum leptophyllum in 1965 (Frahm 2002). All European localities of this moss are ecologically very similar It grows on sandy edges of forest roads in pine or in mixed oak-pine forests, as well as in young pine plantations and heath-lands; less frequently Campylopus introflexus was recorded on dried peat (Frahm 1984; Berg 1985). In some of its western localities the moss covered quite big surfaces, of about 3-4 square meters It seems that the species colonizes mainly disturbed habitats and ecosystems; it was noted mostly at the edges of pine plantations, on the road sides in coniferous forests, frequently in pine stands growing on the acidophilous oak forests habitat.
