Vascular plant biodiversity richness and endemo relictness of the karst mountains Prenj–Čvrsnica–Čabulja in Bosnia and Herzegovina (W. Balkan)

The complex of karstic mountains Prenj-Čvrsnica and Čabulja in Herzegovina (w. Balkan) is characterized by high level of both geomorphology and biodiversity richness. This has been confirmed by a research of plant communities, their structure and dynamics, which took place throughout several seasons from 2005 to 2008. In the investigated area the vegetation cover, as a reliable indicator for specific karstic circumstances, is being differentiated in a great number of syntaxa (plant communities) that encompass over 2,500 vascular plants. On the surface of about 100,000 ha identified were up to 236 plant associations, 116 alliances and 63 vegetation orders that belong to 34 classes. This amounts 34% of total of vegetation classes at the European level and 100% of so far known vegetation classes in Bosnia and Herzegovina, over 80% of classes at the level of Montenegro and Croatia.There have been identified nearly 450 endemic and relict species, which is why most of the identified communities are endemic and relict ones, not only at the level of association but also at the level of higher syntaxonomic categories, such as alliance and order. The highest diversity level characterizes those communities that make a direct contact with the calcareous geological foundation either in rock crevices or screes on limestone. That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean.That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean. Such pattern of vegetation (syntaxonomy) and floristic diversity confirms the unique role of dinaric-herzegovina karst as a complex of unrepeatable ecological factors on global scale

Epipelonske dijatomeje u Šerićkoj bari (sjeveroistočna Bosna i Hercegovina)

Epipelic diatom communities were studied in the Šerićka bara marsh in northeast Bosnia and Herzegovina throughout 2009. During spring and summer a total of 57 species was found at 6 sampling points. The highest number of species was noted for genera Gomphonema (8) and Nitzschia (5). The most abundant species were Melosira varians C.Agardh, Gyrosigma acuminatum (Kützing) Rabenhorst, Lemnicola hungarica (Grunow) F.E.Round & P.W.Basson, Navicula cryptocephala Kützing, Cocconeis placentula var. placentula Ehrenberg, Hippodonta capitata (Ehrenberg) Lange-Bertalot, Metzeltin & Witkowski, Fallacia pygmaea (Kützing) A.J.Stickle & D.G.Mann, Anomoeoneis sphaerophora E.Pfi tzer, Craticula cuspidata (Kutzing) D.G.Mann, Cyclotella meneghiniana (Kutzing) D.G.Mann and Tryblionella hungarica (Grunow) Frenguelli. The spatial variation of the epipelic community was higher in summer as summarized by PCO analysis. Values of the Shannon-Wiener Diversity Index ranged from 2.47 to 2.96, while the Rott Trophic Index ranged from 2.7 to 3.4. Most of the species were eutraphentic (61%) and alkaliphilous (60%), indicating the eutrophic and polytrophic status of this wetland.U radu su istraživane epipelonske zajednice dijatomeja tijekom 2009. godine u Šerićkoj bari u sjeveroistočnoj Bosni i Hercegovini. Determinirano je 57 vrsta na 6 lokaliteta u proljetnoj i ljetnoj sezoni uzorkovanja. Rodovi najbrojnij i vrstama su Gomphonema (8) i Nitzschia (5), a dominantne vrste bile su Melosira varians C.Agardh, Gyrosigma acuminatum (Kützing) Rabenhorst, Lemnicola hungarica (Grunow) F.E.Round & P.W.Basson, Navicula cryptocephala Kützing, Cocconeis placentula var. placentula Ehrenberg, Hippodonta capitata (Ehrenberg) Lange-Bertalot, Metzeltin & Witkowski, Fallacia pygmaea (Kützing) A.J.Stickle & D.G.Mann, Anomoeoneis sphaerophora E.Pfizer, Craticula cuspidata (Kutzing) D.G.Mann, Cyclotella meneghiniana Kutzing i Tryblionella hungarica (Grunow) Frenguelli. Struktura epipelonske zajednice bila je prostorno raznolikija u ljetnoj u odnosu na proljetnu sezonu uzorkovanja. Shannon-Wienerov indeks raznolikosti iznosio je od 2,47 do 2,96, dok se trofički indeks prema Rott-u kretao u rasponu od 2,7 do 3,4. Najveći broj vrsta pripadao je kategoriji alkalifi lnih (60%) i eutrofnih (61%) pokazatelja i upućuje na eutrofni i politrofni status močvare

Alge i makrofiti kopovskih jezera šireg područja Tuzle, Bosna i Hercegovina

The algal and macrophytic occurrence in the pit lakes of the wider area of Tuzla (Bosnia and Herzegovina) was investigated in 2008. The purpose of this investigation was to establish the qualitative composition and the relative abundance of the phytobenthos and epiphyton communities and the structure of the aquatic vegetation in the littoral area of the seven pit lakes. The basic physical and chemical parameters were measured and in total 73 algal taxa and 8 macrophytic species were determined. Most of the algal species belonged to Bacillariophyceae. The macrophytic vegetation was differentiated into two types of habitat. Using the statistical method of the numeric classification, a grouping of samples of phytobenthos and epiphyton compared to the habitat type in which samples were taken was established.Struktura zajednica algi i makrofita je istraživana tijekom 2008. godine na umjetnim jezerima koja su nastala na mjestima okončane površinske eksploatacije ugljena u široj okolici Tuzle (Bosna i Hercegovina). Cilj istraživanja bio je utvrđivanje kvalitativnog sastava i relativne brojnosti algi i makrofita u litoralnom području sedam umjetnih jezera. Mjereni su osnovni fizikalno-kemijski pokazatelji, a u uzorcima algi su utvrđena 73 taksona algi, od kojih su najzastupljenije bile dijatomeje. Makrofitska vegetacija s determiniranih 8 vrsta diferencirana je u dva tipa staništa. Koristeći se statističkom metodom numeričke klasifikacije, utvrđeno je grupiranje uzoraka fitobentosa i epifitona u odnosu na tip staništa na kome su uzorkovani

Balkan Vegetation Database (BVD) – updated information and current status

The Balkan Vegetation Database (BVD; GIVD ID: EU-00-019) is a regional database, which was established in 2014. It comprises phytosociological relevés covering various vegetation types from nine countries of the Balkan Peninsula (Albania – 153 relevés, Bosnia and Herzegovina – 1715, Bulgaria – 12,282, Greece – 465, Croatia – 69, Kosovo – 493, Montenegro – 440, North Macedonia – 13 and Serbia – 2677). Currently, it contains 18,306 relevés (compared to 9.580 in 2016), and most of them (82.8%) are geo-referenced. The database includes both digitized relevés from the literature (65.6%) and unpublished data (34.5%). Plot size is available for 84.7% of all relevés. During the last four years some “header data information” was improved e.g. elevation (now available for 83.4% of all relevés), aspect (67.7%), slope (66%), total cover of vegetation (54.3%), cover of tree, shrub, herb, bryophyte and lichen layers (27.1%, 20.1%, 40.2%, 11.5% and 2.1%), respectively. Data access is either semi-restricted (65.6%) or restricted (34.4%). Most relevés (84.6%) are classified to syntaxa of different levels. The database has been used for numerous studies with various objectives from floristic, vegetation and habitat-related topics, to macroecological studies at the local, regional, national, continental and global levels. During the last four years, BVD data were requested from 111 different projects via the EVA and sPlot databases
