We monitored trace metals and nitrogen using naturally growing moss Hypnum cupressiforme Hedw. in urban and peri-urban forests of the City Municipality of Ljubljana. The aim of this study was to explore the differences in atmospheric deposition of trace metals and nitrogen between urban and peri-urban forests. Samples were collected at a total of 44 sites in urban forests (forests within the motorway ring road) and peri-urban forests (forests outside the motorway ring road). Mosses collected in urban forests showed increased trace metal concentrations compared to samples collected from peri-urban forests. Higher values were significant for As, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Tl and V. Within the motorway ring road, the notable differences in element concentrations between the two urban forests were significant for Cr, Ni and Mo. Factor analysis showed three groups of elements, highlighting the contribution of traffic emissions, individual heating appliances and the resuspension of contaminated soils and dust as the main sources of trace elements in urban forests.

A moss genus Herzogiella, from the pleurocarpous family Plagiotheciaceae contains only seven species world wide. It occurs in North, Central and South America, Europe and Asia. In Europe, only three species occurred, namely H. seligeri, H. striatella and H. turfacea of which, the last one is threatened. With aim to develop the methodology for protection, conservation and active propagation of H. turfacea, more commonly distributed counterpart, H. seligeri, were taken from the National Park Fruška Gora and axenically culture were established. The study gives overview into the problems of sterilization, in vitro establishing, development, propagation and biology of species, as well as indices applicable to threatened counterpart.

The bryophytes of the Balkan Peninsula are still very poorly known, and the region of South-Eastern Europe is bryologically the less investigated area in Europe. The aim of this study is to evaluate the stage of bryophyte flora knowledge and bryophyte diversity richness in the Balkan Peninsula compared to Europe. Thus, species richness (alpha diversity) and the size of territories, and their logarithmic ratio, are taken into consideration. At the present, bryophyte flora in the region of SE Europe counts 5 hornworts, 267 liverworts and 897 moss species. It comprises 59.9 % of European hepatic and 69.4 % of moss flora. The richest territories in hepatic species are Romania (197 sp.) followed by Bulgaria (170 sp.) and Slovenia (167 sp.). On the other side, the poorest territories in hepatic species are the European part of Turkey (27 sp.), FYR of Macedonia (69 sp.) and Albania (91sp.). Similarly, the moss flora counts most species in Romania (747 sp.) followed by Slovenia (637 sp.), Bulgaria (558 sp.) and Serbia (553 sp.). One hundred and twenty mosses (12.9 %) and 42 (16.1 %) hepatic species are known from only one of eleven regional territories of SE Europe. The picture can be drown with the species recorded in only two of eleven territories : 149 mosses (16.9 %) and 57 hepatics (20.95 %). Besides, many species described from the region in the past still remain open to investigation regarding their taxonomic status. In the last years, there have been high activity in bryophyte investigation in SE Europe, and data on regional bryoflora constantly increase. However, achieving recent data on bryophytes within SE Europe remains still a problem to face. Intensive investigation of bryophytes in SE Europe is urgently needed, just to approach the level of knowledge in other well-known European regions., Aperçu de la diversité de la flore des bryophytes de la péninsule des Balkans dans le contexte européen. Les bryophytes de la péninsule Balkanique sont toujours très pauvrement connues et, au point de vue bryologique, l’Europe du Sud-Est demeure la région la moins prospectée en Europe. Le but de cette étude est d’évaluer l’état des connaissances sur la richesse de la diversité des bryophytes dans la péninsule Balkanique par rapport à l’Europe. Ainsi, la richesse spécifique (diversité alpha), la taille des territoires et leur rapport logarithmique sont pris en considération. Actuellement, la flore bryologique compte, dans le S.-E. de l’Europe, 5 anthocérotées, 267 hépatiques et 897 espèces de mousses. Elle comporte 59,9 % des hépatiques européennes et 69,4 % de la flore des mousses. Les territoires les plus riches en hépatiques sont la Roumanie (197 sp.), suivie par la Bulgarie (170 sp.) et la Slovénie (167 sp.). À l’opposé, les territoires les plus pauvres en hépatiques sont la partie européenne de la Turquie (27 sp.), la FYR de Macédoine (69 sp.) et l’Albanie (91 sp.). De même, la flore des mousses compte la plupart des espèces en Roumanie (747 sp.), suivie par la Slovénie (637 sp.), la Bulgarie (558 sp.) et la Serbie (553 sp.). Cent vingt mousses (12,9 %) et 42 hépatique (16,1 %) sont connues de seulement un des onze territoires régionaux de l’Europe du S.-E. L’image peut être complétée avec les espèces enregistrées dans seulement deux des onze territoires : 149 mousses (16,9 %) et 57 hépatiques (20,95 %). De plus, beaucoup d’espèces décrites de la région dans le passé restent toujours en attente d’une enquête quant à leur statut taxinomique. Dans les dernières années, il y a eu une hausse de l’activité d’enquête sur les bryophytes du S.-E. de l’Europe et les données sur la flore bryologique régionale augmentent constamment. Néanmoins, l’obtention de données récentes sur les bryophytes du S.-E. de l’Europe reste toujours un problème d’actualité. Une enquête intensive des bryophytes du S.-E. de l’Europe est une urgente nécessité, ne serait-ce que pour approcher le niveau de connaissance d’autres régions européennes bien connues., Sabovljević Marko,Alegro Antun,Sabovljević Aneta,Marka Jani,Vujičić Milorad.

Pogonatum urnigerum (Polytrichaceae) in vitro culture was established from spores collected in nature. Both protonema and gametophore stages of gametophyte development were obtained. Also, a stable callus culture was established using hormone-free nutrient medium. The best nutrient medium for development was half-strength Murashige-Skoog medium supplemented with 1.5% sucrose. Auxin treatment enabled some gametophores to develop, but prolonged treatment induced early senescence. Tissues grown on cytokinin did not produce any gametophytes and did not survive prolonged treatment. Sterilna kultura mahovine Pogonatum urnigerum (Polytrichaceae) uspostavljena je iz spora sakupljenih u prirodi. Gajenjem na hranljivoj podlozi bez biljnih hormona iz spora su se razvile protoneme i gametofiti. Uspostavljena je i stabilna kultura kalusa. Ustanovljeno je da je za gajenje ove vrste najbolja hranljiva podloga koja sadrži smanjenu koncentraciju soli i vitamina po Murashige-Skoog-u i 1.5% saharozu. Tretman auksinom nije pospešio razviće gametofita, dok je produženi tretman doveo do postepenog odumiranja protoneme. Tkiva gajena na podlozi koja je sadržala citokinine uopšte nisu produkovala gametofite i nisu preživela produženi tretman ovim hormonom. Ovaj rad predstavlja prvu studiju razvića vrste Pogonatum urnigerum u in vitro kulturi. null

The moss species Atrichum undulatum (Hedw.) P. Beauv. (Polytrichaceae, Bryophyta) is widespread throughout the northern hemisphere. Selected accessions from Europe (23) have been studied based on 5 enzymes and their isoforms with aim to reveal genetic diversity. The results obtained clearly show that there is a high genetic diversity in Atrichum undulatum within the samples tested. However, the results do not document any distributional pattern or any special gradient based on genetical analyses.

An ecological and distributional approach of the urban bryoflora of the city of Belgrade has been made. Many different parameters and indices have been analyzed with aim to infer the significance and get better idea on the bryophytes within the urban areas. Mosses significantly dominate over liverwort species in urban conditions, and the most common life forms are turfs and rough mats. Small spores (less than 20μm) are abundant if sex reproduction is present among mosses. Urban environment conditions decrease sex and increase vegetative reproductive effort by producing many kind of vegetative propagules in the most of the species recorded. As expected, due to geographical position and climate, dominant distribution types within urban bryophyte flora of Belgrade is temperate.

Syntrichia norvegica is a circumpolar arctic- montane species (Smith, 2004), rare at lower altitudes and in southern Europe (Frey et al., 2006). It is known from several south-eastern European countries (Sabovljevic et al., 2008) and now it is recorded for the first time in Croatia. Regarding its conservation status, S. norvegica is red listed in Great Britain (EN), Czech Republic (CR), Slovakia (VU), Bulgaria (NT), Hungary (DD), Romania (VU) and Estonia (VU) (Hodgetts, 2014). It was found in the northern Velebit Mountains, in an area with the most outstanding and extreme karst relief, with steep slopes, perpendicular rocks, screes and deep dolines. The locality is situated in the Pinus mugo Turra belt, but owing to its position in the shaded bottom of a deep, funnel-shaped doline with slopes inclined at more than 70u, the zonal vegetation is replaced by frigoriphilous communities. The main community on the very bottom is Drepanoclado uncinati-Heliospermetum pusillae Surina & Vres 2004, which encompasses many species of cold habitats characterized by long-lasting snow cover, e.g. Saxifraga sedoides L. subsp. prenja (Beck) Beck (glacial relict in the Velebit), Heliosperma pusillum (Waldst. & Kit.) Rchb., Polygonum viviparum L., Myosotis alpestris F.W.Schmidt, Poa alpina L. and Festuca nitida Kit. This community was spread over ca 250 m2 and was bordered by low shrubs of Salix waldsteiniana Willd., which form another frigoriphilous community Salicetum waldsteinianae Beger 1922. In the moss flora, another arctic- montane species, Cyrtomnium hymenophylloides (Huebener) T.J.Kop., is very abundant, and this is the only known locality in Croatia (Blockeel et al., 2009c). Further bryophytes that were present include Sanionia uncinata (Hedw.) Loeske, Orhothecium rufescens (Dicks. ex Brid.) Schimp., Campylium protensum (Brid.) Kindb., Campylophyllum halleri (Hedw.) M.Fleisch., Sciuro-hypnum reflexum (Starke) Ignatov & Huttunen, Platydictya jungermannioides (Brid.) H.A.Crum, Hypnum bambergeri Schimp., Plagiopus oederianus (Sw.) H.A.Crum & L.E.Anderson, and Plagiochilla porelloides (Torr. ex Nees) Lindenb. among others. The population of S. norvegica was vigorous, forming dozens of dense patches of several dm2 on rocks and among other bryophytes and herbs. Plants were typically developed, deep green, with long, reddish leaf points, but capsules were not found.

The names of all mosses published up to the end of August 2011 in the countries of the Mediterranean basin, the Macaronesian Islands and Bulgaria are compiled in an annotated checklist. The list comprises accepted names and synonyms, and provides explanatory annotations for ambiguous and disputed names. Literature references supporting the reports in each individual area are given only for taxa reported once or in a single locality. A total of 1168 accepted species and 81 infraspecific taxa are reported from the whole area.
