Overview of bryophyte flora research in Serbia with presentation of the Serbian BRYO database
Pantovic J &Sabovljevic MS
Pages 153-162
Full reference | Abstract | Full text PDF

ABSTRACT: Bryophyte flora research in Serbia was rather sporadic until the end of the 19th century, when a group of mostly high-school teachers started researching bryophytes. This was the first fruitful period of exploration, with many new country records. Thereafter, not many researchers investigated bryophytes in Serbia, and the majority of chorological data came from vegetation, ecological, or palaeobotanical studies. This lasted until the 1990s, when a revival of bryophyte investigation occurred, bringing with it many floristic studies and new species records for the country. At the present time, Serbia is considered to be rich in bryophyte diversity, with as many as 797 species. However, further study and a critical approach to the bryophyte flora of Serbia are needed.

ABSTRACT: Atlas Florae Europaeae (AFE), a programme for mapping the distribution of vascular plants in Europe, was launched in 1965 as a collaborative effort between European botanists. A historical review of the mapping for AFE in the Balkan countries, cited in the last volume (16) from 2013 as Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Former Yugoslav Republic (F. Y. R.) of Macedonia, Greece, Kosovo, Montenegro, Serbia, Slovenia, and Turkey (European part), is presented and achievements and problems discussed. The special challenges facing mapping of the Balkan area during the past 50 years include the extremely rich flora, diverse and mountainous relief, political and economic difficulties, inaccessibility of available data, and scarcity of botanists contributing and collecting data for mapping.

Full reference | Abstract | Full text PDF

ABSTRACT: Due to complex and heterogeneous geographical characteristics, Serbia is represented by a diverse flora with many endemic taxa of vascular plants. Investigation of plant endemics stored in the national herbaria and perusal of extensive literature sources indicate that 46 taxa occur exclusively within the political borders of the Republic of Serbia, while 104 taxa can also be found in adjacent countries of the Balkan Peninsula. These national and subendemics are presented in the form of a list together with their ecological and geographical characteristics. Centres of endemism are located in the southern and eastern regions of Serbia and on the territory of Kosovo and Metohija. The majority of taxa are associated with mountainous regions of Kosovo, Metohija, and Central Serbia, at medium elevations between 500 and 1500 m. Most of the national endemics occur on limestones and dolomites and on soils such as cambisols, lithosols, and rankers. They are mainly under the influence of a modified mountain and moderately continental climate.

Diversity of chasmophytes in the vascular flora of Greece: floristic analysis and phytogeographical patterns
Panitsa M &Kontopanou A
Pages 199-211
Full reference | Abstract | Full text PDF

ABSTRACT: Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa. A main database has been prepared which includes vascular plant taxa that are obligate or facultative chasmophytes and also contains information about their life form, chorology, protection status, occurrence in more than 135 places such as cliffs, gorges, or open rocky habitats, and their geographical distribution in the 13 phytogeographical regions of Greece based on available floristic, vegetation, and phytosociological literature and on the authors’ own collections and observations. The paper presents an analysis of the total diversity of cliff plant species, as well as the diversity of obligate chasmophytic plant species, endemics, and range-restricted taxa, in addition to the results of studying the distribution patterns of different subsets of plant taxa in the different phytogeographical regions of Greece. Hemicryptophytes and chamaephytes are the dominant life forms of the chasmophytic taxa. Among 935 species and subspecies registered, 476 are obligate chasmophytes, of which the majority are Greek endemics. Hierarchical cluster analysis of different subsets of plant taxa revealed affinities of the cliff flora of different phytogeographical regions. Additionally, 15 chasmophytic taxa mentioned in Annexes II, IV, and V of EEC Directive 92/43 belong to the cliff flora, of which 10 are obligate chasmophytes and nine have a priority for protection. Eighteen taxa are included in the IUCN Red List of Threatened Species, of which four are critically endangered (CR), seven are vulnerable (VU), and three are endangered (EN). The distinct correlation between endemism and chasmophytic ecology is emphasized, since a detailed understanding of the local distribution and specific habitats of rare plants provides an opportunity for local conservation efforts that can influence biodiversity conservation on a larger scale.

Pages 213-219
Full reference | Abstract | Full text PDF

ABSTRACT: We present in this paper the first assessments, made by means of flow cytometry, of nuclear DNA amounts in one genus, 11 species, and one variety (including the first data from wild material in the case of one of the species), all of them from the family Asteraceae. Chromosome numbers are provided for three of these taxa, the presented material including new data for one species. These data complement existing information on plant genome size in the largest plant family.

ABSTRACT: Although it is well known that dry open rocky grassland vegetation on shallow serpentine (ultramafic) soils represents one of the most interesting, highly endemic, and often studied vegetation types, the authors of several detailed studies of Balkan serpentine flora and vegetation suggested that the vegetation cover of Balkan ultramafics needs further exploration due to its heterogeneity. In this article, phytosociological characteristics of seven poorly known associations of grassland communities from the order Halacsyetalia sendtneri are analysed. In order to provide additional descriptions of these communities (with diagnosis and lists of diagnostic, dominant, and constant species), check their phytosociological validity, and confirm their syntaxonomical position, the stands of these communities were compared with 18 associations distributed throughout the area of serpentine outcrops in Bosnia and Herzegovina and Serbia. The results of cluster analysis confirmed that the analysed heretofore poorly known associations in the vegetation of open rocky serpentine grasslands are floristically well-defined.

Spread of Sporobolus neglectus and S. vaginiflorus (Poaceae) in Slovenia and neighbouring countries

Pages 249-256
Full reference | Abstract | Full text PDF| Appendix

ABSTRACT: Systematic field sampling revealed that within 50 years since the first records in Slovenia, Sporobolus neglectus and S. vaginiflorus became widespread. They are two superficially similar N American annual grass species with cleistogamous spikelets and similar ecology that are confined to dry ruderal places in their European secondary range, especially along roads. The oldest records of naturalised populations of both species in Europe date back to the 1950s, when both were found for the first time in the Vipava valley (SW Slovenia). They spread slowly in the next decades to NE Italy, N Croatia, and S Austria until recently, when an explosive expansion has been observed along almost all the main roads in lowland and montane Slovenia. In addition to that, one or both of them have recently been recorded scattered in SE Europe (Hungary, Serbia, B&H, Montenegro) and W Europe (France, Switzerland). Sporobolus vaginiflorus is herein reported for the first time for Serbia, Herzegovina (in B&H), and Slavonia (in Croatia).
