Abstract

ABSTRACT This paper presents the occurrence of 25 moss species on trunks of alien trees in Wrocław (without city forests), their species diversity, frequency, coverage in the plots, and preferences to the host-tree species. In general, 36% of the trees colonised by bryophytes in the city were of non-indigenous origin (11 taxa), and the most frequently occupied were Populus xcanadensis Moench., Acer negundo L. and Robinia pseudoacacia L. Research showed that alien trees hosted a large group of species rarely noted in the city, such as: Syntrichia virescens (De Not.) Ochyra, Orthodicranum tauricum (Sapjegin) Smirnova, Leskea polycarpa Hedw., Hypnum pallescens (Hedw.) P. Beauv. and Orthotrichum affine Schrad. ex Brid. But the most total coverage in the plots was occupied by two facultative epiphytes, Orthotrichum diaphanum Schrad. and Hypnum cupressiforme Hedw. Comparing the results of this study with data presenting bryoflora of Robinia pseudoacacia L. and Quercus rubra L. found in secondary woodlands, it appears that these phorophytes in the city are colonised by different bryophytes. Results of UPGMA classification of bryofloristic similarity of all phorophytes in the city are discussed in reference to the theory that alien species can facilitate the occurrence of native species, as formulated by Rodriguez (2006).

Wrocław(波兰西南部)外来寄主树种上的附生苔藓植物

摘要:本文报道了Wrocław(无城市森林)外来乔木树干上25种苔藓的发生情况、物种多样性、频率、样地盖度以及对寄主树种的偏好。总体而言，被苔藓植物占领的乔木中有36%(11个类群)为非本地来源，其中以加拿大杨(Populus xcanadensis Moench)占据最多。研究表明，外来树木中有大量在城市中很少发现的物种，如:绿针藓(Syntrichia virescens, De Not.)Ochyra, Orthodicranum tauricum (Sapjegin) Smirnova, Leskea polycarpa Hedw。，淡紫色(hew .)测定。和仿射赤藓。Brid交货。但总盖度最高的是兼性附生植物赤藓(Orthotrichum diaphanum Schrad)。和hypum cupressiforme hew。将本研究结果与次生林地中刺槐(Robinia pseudoacacia L.)和红栎(Quercus rubra L.)苔藓植物区系数据进行比较，表明城市次生林地中这些苔藓植物是由不同苔藓植物定殖的。参考Rodriguez(2006)提出的外来物种可以促进本地物种发生的理论，讨论了UPGMA对城市所有植虫区系相似性的分类结果。
