Many of the open-pit mines have been abandoned, and the measures of the phytoremediation and restoration of ecosystems have not been implemneted. Permanent water bodies have been formed on such abandoned open-pit mines (pit lakes). The process of creation of wetlands of this type is the opposite to the trend of loss of wetlands in the world. This paper presents the research results of physico-chemical analysis of water taken from six explored pit lakes in the Zenica-Doboj Region, and the analysis of macrophytes and macrophyte vegetation. Physico-chemical analysis has identified a favorable water quality at all six explored pit lakes. Water taken from all the explored pit lakes have a neutral to slightly alkaline pH value, with favourable oxygen regime and slightly increased concentrations of nitrate, ammonium, sulfate and iron. The phytobentosof the explored pit lakes are characterized by the following species of cyanobacteria and algae: Oscillatoria princeps, Peridinium bipes, Dinobryon divergens, Cocconeis placentula, Cymbella neocistula, Eunotia turgida, Botryococcus braunii, Amphypleura pellucida, Rhopalodia gibba, Eucocconeis flexella, Scenedesmus quadricauda, Closterium moniliferum etc. The macrophyte vegetation is represent in three types of habitats including: hard oligo-mesotrophic Waters with submerged benthic vegetation of Charophyta (Chara sp., Nitella sp., Natura code 3140), eutrophic standing water (Magnopotamion, Natura code 3150) and wetland vegetation (Phragmitetea, Natura code 7230). By applying the method of correspondent analysis, it has been found that diversity of macrophytes community depends on the age of the lake and the Development of macrophyte vegetation. Based on the Research conducted on the conditions of the pit lakes in the Zenica-Doboj Region, it can be concluded that these water bodies represent a good basis for restoration and conservation activities, but also for the Protection of the wetland biodiversity. Key word: mine-pit lake, phytobenthos, restoration, cyanobacteria, algae.

Peatlands are widespread on the North, where they occupy large areas of northern Europe, Asia and Canada. Occurrence of this type of ecosystems in Bosnia and Herzegovina contains an indication of nature conservation in general and represents an extraordinary natural value. The status of peatland ecosystems in the Balkans should be carefully monitored especially today, at the time of the already recognizable effects of climate change. The preserved structure and functionality of these ecosystems might indicate satisfactory degree of resilience to climate change, but adverse state warns on the need to take appropriate actions. Multiply drivers as overexploitation of natural resources, water, air and soil pollution and spread of invasive alien species, also have a negative effect o...

Spatial ecological modelling is a promising toolbox for understanding the past, present and future distribution and diversity patterns in groundwater-dependent ecosystems, such as fens, springs, streams, reed beds or wet grasslands. Still, the lack of detailed water chemistry maps prevents the use of reasonable models to be applied on continental and global scales. Being major determinants of biological composition and diversity of groundwater-dependent ecosystems, groundwater pH and calcium are of utmost importance. Here we developed an up-to-date European map of groundwater pH and Ca, based on 7577 measurements of near-surface groundwater pH and calcium distributed across Europe. In comparison to the existing European groundwater maps, we included several times more sites, especially in the regions rich in spring and fen habitats, and filled the apparent gaps in eastern and southeastern Europe. We used random forest models and regression kriging to create continuous maps of water pH and calcium at the continental scale, which is freely available also as a raster map (Hájek et al., 2020b; https://doi.org/10.5281/zenodo.4139912). Lithology had a higher importance than climate for both pH and calcium. The previously recognised latitudinal and altitudinal gradients were rediscovered with much refined regional patterns, as associated with bedrock variation. For ecological models of distribution and diversity of many terrestrial ecosystems, our new map based on field groundwater measurements is more suitable than maps of soil pH, which mirror not only bedrock chemistry but also vegetation-dependent soil processes.

These types of habitats occur in the wide area of Vranica Mountain. During our research (August and September 2018) of freshwater habitats in this area, rare golden macroalgae Hydrurus foetidus (Villars) Trevisan was found. It has been already detected in Bosnia and Herzegovina, but in this study new localities are presented. Water temperature, pH, dissolved oxygen, specific electrical conductivity, turbidity and total dissolved solids were measured on sampling sites. In addition to the analysis of ecological characteristics of habitats, diatom assemblages were analysed. In this study a total of 48 diatom taxa belonging to 25 genera were identified. The results of diatom indices confirmed the good water quality of the studied sites on which H. foetidus was found. This study represents a contribution to algological research in Bosnia and Herzegovina.

Due to nature of their formation, these lakes may contain various heavy metals that might have an adverse effect on diversity of phytobenthos. The objective of this paper is the analysis of the phytobenthos assemblages in the mine pit lakes and assessment of the effects of certain heavy metals on diversity of this group of organisms. Special emphasis of this work is to determine the presence of tolerant species of algae on heavy metal pollution in mine pit lakes and their application in biomonitoring. The field research was performed during autumn season in 2014, at six mine pit lakes in the territory of B&H. The following heavy metals were analysed Al, Cr, Zn, Ni and Fe. The results were discussed in terms of confirmation or rejection of the hypothesis on the adverse effect of heavy metals on diversity ...

Today, they are colonised by different types of organisms, where algae hold a special place in their biocenosis. For the purpose of this paper, ecological conditions and phytobenthos assemblages were compared in two mine pit lakes in Bosnia and Herzegovina (Veovača and Bistrik). Samples of the phytobenthos are collected during the summer and autumn season in 2013 and 2014. Analysis of the basic physical and chemical properties of the water was also performed. The research is based on cyanobacteria and algae samples collected in accordance with the methodology in compliance with the standards of the European Union Water Framework Directive (WFD, 200/60/EC). The multivariate statistical analysis was performed by using the software package PRIMER v6. With the aim of understanding the ecological differentiation of the phytobenthos assemblages with reference to the gradient of the measured physical and chemical parameters, the cluster and PCO analyses were used. The aim of the paper is to analyse the algae diversity with reference to different ecological conditions in the research area.

Study area: Inner-alpine valleys of Austria. Methods: We sampled 67 plots of 10 m 2 , following the standardized EDGG methodology. We subjected our plots to an unsupervised classification with the modified TWINSPAN algorithm and interpreted the branches of the dendrogram syntaxonomically. Biodiversity, structural and ecological characteristics of the resulting vegetation units at association and order level were compared by ANOVAs. Results: All the examined grasslands belong to the class Festuco-Brometea. From ten distinguished clusters, we could assign four clusters to validly published associations, while the remaining six clusters were named tentatively. We classified them into three orders: Stipo-Festucetalia pallentis (Armerio elongatae-Potentilletum arenariae, Phleo phleoidis-Pulsatilletum nigricantis, Medicago minima-Melica ciliata community, Koelerio pyramidatae-Teucrietum montani), Festucetalia valesiacae (Sempervivum tectorum-Festuca valesiaca community); Brachypodietalia pinnati (Astragalo onobrychidis-Brometum erecti, Agrostis capillaris-Avenula adsurgens community, Anthericum ramosum-Brachypodium pinnatum community, Ranunculus bulbosus-Festuca rubra community, Carduus defloratus-Brachypodium pinnatum community). Conclusions: The ten distinguished dry grassland communities of the Austrian inner-alpine valleys differ in their ecological affinities as well as their vascular plant, bryophyte and lichen diversity. We point out their high nature conservation importance, as each of them presents a unique habitat of high value.
