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.), B...

Up to date there are 24 Grimmia species known for Albania and 18 for Kosovo. Albania and Kosovo both have a rich Grimmia flora, due to geographic position and high mountain ranges with diverse rock types. There are three Grimmia species for Albania which have threat status, all vulnerable (VU), in the checklist and country status of European bryophytes: Grimmia crinita, G fuscolutea and G. mollis. Many more species have conservation value in the context of SE Europe, especially in Bulgaria and Romania. However for Albania and Kosovo several other species seem to be rare and should be considered for future conservation: Grimmia anodon, G. elongata, G. caespiticia, G. decipiens, G. longirostris and G. reflexidens.

A bryophyte red list is lacking as well. Since it is not yet possible to use the IUCN criteria guidelines proposed for bryophytes, the aim of the present contribution is to compile a list of the bryophyte taxa from Albania with, wherever possible, the inclusion of conservational values, according to the European Bryophyte Red Data Book or other regional red lists (e.g. those existing for Serbia, Montenegro, Bulgaria and Romania). Hence, 16 liverwort species (ca 17% of the total) and 64 moss species (ca 18%) are taken into account. For an improved red list of the bryophytes of Albania extensive exploration and collecting is greatly needed in the country. Th e hereby presented account should be considered as a tentative one. Th is preliminary version of a red list is provided with the aim to highlight the "national red list candidate" bryophyte species, which might need to be included in further natural heritage conservation initiatives in Albania. Even until then it is clear that there is an urgent need for the protection of the bryophytes in Albania.

The aim of this study was to increase that knowledge by investigating Sharri National Park for its moss flora. Several field trips were carried out in 2014, 2015 and 2018. About 1900 specimens were collected in various locations of the Park (e.g. Brezovicë, Prevallë, Prroi i Duhlës, Ostrovicë, Restelicë, Mushtishtë, Pashallarë, Burimi i Lumbardhit etc.). Thus far, most of the specimens are identified and represent 159 moss taxa. Seventy-three taxa are new records for Sharri National Park, in which a total of 255 moss taxa have now been reecorded. Furthermore, 19 species are new records for Kosovo, which is now known to have a total of 346 moss taxa. The new records are for Amphidium lapponicum, Blindiadelphus recurvatus, Brachythecium geheebii, Dicranella schreberiana, Didymodon rigidulus, Grimmia dissimulata, G. muehlenbeckii, G. trichophylla, Kiaeria starkei, Paraleucobryum longifolium, Pohlia melanodon, Ptychostomum elegans, Racomit...

Nine species (Bryum ruderale, Fissidens adianthoides, F. crassipes, Grimmia fuscolutea, G. meridionalis, Orthotrichum patens, O. philibertii, Tortella fasciculata, T. infl exa) were collected for the fi rst time in Albania. 31 species found have conservation interest; rare on the Balkans or even in Europe or/and candidates of the new European bryophyte red-list.

The high number of new records reflects the poor state of our knowledge of the bryoflora of the country. Many of the newly recorded species have Alpine, Boreal or even Arctic affinities. However the most significant record is that of Jungermannia calcicola Konst. & Vilnet., previously known only from the Russian Caucasus.

Altogether 145 trees were investigated for epiphytic mosses during the spring of 2016. Altogether 553 moss samples were collected resulting in a total of 40 moss taxa, 19 taxa for strictly urban area and 39 for park area, with 18 taxa being in common for both communities. For the strictly urban area the fi ve most common species were Orthotrichum diaphanum, Syntrichia papillosa, Fabronia pusilla, Homalothecium sericeum and Syntrichia laevipila. From the other side, the fi ve most common species of the Park area were Hypnum cupressiforme, Homalothecium sericeum, Syntrichia papillosa, S. laevipila and Leucodon sciuroides. Th e values of biodiversity indices were higher for the park area, and the similarity between these two communities was of average degree. Among the epiphytic mosses recorded some are resistant to air pollution and others are sensitive to it. Th e question if the diff erences seen between the two communities are only a consequence of microclimatic conditions remains open, as a long term monitoring of biodiversity dynamics will be needed on the one hand and a standardised method to check for correlations between biological parameters and chemical-physical parameters on the other hand.

This research is a part of the international program (International Cooperative Programme (ICP) Vegetation, UNECE) carried out in most European countries since 1987, investigating the impacts of air pollutants on crops and natural vegetation. Sampling was carried out during the dry seasons of autumn 2010 and summer 2011 at 62 sites distributed all over Albania. Unwashed, dried samples were totally digested by using microwave digestion, and the concentrations of metal elements were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The results reflect local emission points. Only the elements with high values of concentration, Al, Cr, Fe, Ni, V, and Zn, compared to other European countries are discussed in this paper. The median values of chromium (4.75 mg/kg, dry weight (DW)), iron (1,618 mg/kg, DW), nickel (5.85 mg/kg, DW), vanadium (3.51 mg/kg, DW), zinc (13.77 mg/kg, DW), and aluminum (6,974 mg/kg, DW) are similar to those of neighboring countries but higher than those of European countries. An exponentially weighted moving average (EWMA) and univariate control chart was used to investigate the moving range of successive observations and to estimate the variability of the data. Certain local emitters were identified like the iron-chromium metallurgy and cement industry, oil refinery, mining industry, and transport. In addition, natural sources, such as the accumulation of these metals in mosses caused by metal-enriched soils, associated with the wind blowing soils particularly in the southeast direction of the country, were pointed as another local emitting factor.

The number of taxa reported is still very low compared with the neighboring countries from one side, and the presence of two important mountain massifs in Kosovo (Bjeshkët e Nemuna/Prokletije and Shar/Šar Mountains) from the other side. Bjeshkët e Nemuna (BN) is made up of many large mountains located in three different countries (Albania, Kosovo and Montenegro) of the Balkan Peninsula. The knowledge of bryoflora of BN is better known for Albania and Montenegro, with recent publications for both countries, whereas there is only one publication for Kosovo. In this context, the results from two field trips (in 2015 and 2019) carried on in various localities (Lagjia e Kaprojve, Reka e Allagës, Liqenat, Bogë and Hajla) in the BN Mountains are presented here. Altogether, 1140 moss specimens were examined, which comprise about 130 taxa. Thirteen species are new records for Kosovo: Calliergonella lindbergii, Campyliadelphus chrysophyllus, Cyrtomn...

The lagoon, with its environs, is one of the most important coastal ecosystems in Albania and includes diverse habitats: coastal sand dunes, pine forests, maquis, shibliak, and marshlands. The number of bryophyte species reported for the area has substantially increased (from 11 to 60), in addition to a few findings in the Orikum Lagoon area (previously bryologically unexplored). Twenty-one entities are new for Albania.

Among them 72 taxa (2 liverworts, 70 mosses) are recorded for the first time in Albania: Conocephalum salebrosum, Marchantia polymorpha subsp. monti-vagans species (Fissidens curvatus, Grimmia sessitana, Pseudoleskea saviana) are included in the Red Data Book of European Bryophytes.
