“…The relatively small number of taxa recorded in Bunica Spring, 104 on natural substrates and 82 on artifi cal substrates, matches the results in the reviewed papers (BLAGOJEVIĆ 1974, SABATER and ROCA 1990, 1992, CANTONATI 1998, TAXBÖCK and PREISIG 2007, HAFNER et al 2008, CANTONATI and SPITALE 2009, ANGELI et al 2010, DEDIĆ et al 2012, WOJTAL and SOBEZYK 2012. Bunica Spring also showed great similarity to the others with regard to the composition of diatom taxa.…”

-This study presents investigations of the periphytic diatoms on artifi cial (glass slides) and natural substrates in the karstic, limnocrene spring of Bunica situated in the south of Bosnia and Herzegovina. Investigations were performed in summer 2010. Samples were collected every seven days for eight weeks. Physical and chemical characteristics of water, temperature, oxygen saturation, dissolved oxygen, electric conductivity and nutrients as well as fl ow velocity at sample site, were measured simultaneously with each sampling. Physical and chemical characteristics showed low temperature oscillations, good aeration and oligotrophic conditions. In general, greater diatom diversity was noted on natural substrate. A total of 104 diatom species were found on natural substrate and 82 on glass slides. The best represented genera on both types of substrate were Gomphonema and Navicula (each with eight species), Nitzschia (with six species), and Cocconeis (with fi ve species). Achnanthidium exiguum, Achnanthidium minutissimum, Amphora pediculus, Cymbopleura amphicephala and Surirella minuta were recorded in all samples of natural substrate and Gomphonema minutum in artifi cial substrate samples.

“…In general, the oxbow lake impacted by anthropogenic pressures and a high average concentration of different ions can be characterized by a high average density of phytoplankton, which were mainly diatoms and coccoid chlorophytes. Both of these algal groups consist of taxa, which are characteristic for polluted waters . But, in the oxbow lake, impacted by the forest ecosystem and subjected to possible temporary lack of availability of nutrients, we observed a high density of mixotrophs, which may use different feeding strategies e.g.…”

In this study, we present the effects of environmental factors on phytoplankton in two different oxbow lakes formed from the Vistula River. One of these lakes is under extreme anthropogenic pressure, i.e. impacted by industrial and municipal effluents and characterized by high water temperature and high concentrations of ions. The other oxbow lake is located in a natural forest with some its abiotic factors lower compared to the first oxbow lake. There were significant changes among environmental parameters, which influenced significant differences between the phytoplankton populations. The dominant algae of the impacted oxbow were small centric diatoms, which are able to rapidly absorb nutrients and have a rapid turnover. The results demonstrated that human impacted lake was a habitat, where species with a broad range of ecological requirements survive. However, these habitats are also more vulnerable for the entry and colonization of invasive algal species. In the forest oxbow lake, without human impact, heterogeneity of water quality parameters resulted in different specific habitats. Oxbow lakes are important as biodiversity hotspots for rare and/or endemic species.

“…However, low-elevation carbonate springs in densely populated areas, directly affected by various types of impacts, have been less considered than near-natural mountain springs. Some information on this type of springs is nevertheless available from Poland (Wojtal 2013;Żelazna-WieCzorek 2011;Wojtal & Sobczyk 2012), Switzerland (taxböck & preiSig 2007), France (bertrand et al 1999), andSpain (aBoal et al 1998;delgado et al 2007, Maiorca). Small springs on carbonate substratum fed by local aquifers are often affected by marked discharge fluctuations and even are intermittent or seasonal.…”

Diatom assemblages in carbonate spring habitats at low elevations, with low discharge, and affected by direct human impacts were studied only recently and in some geographic areas. We describe and characterize the ecology of a new Navicula species from springs with these characteristics within the basin of the River Adige in the south-eastern Alps and Alpine foothills (Province of Verona, Italy). Navicula veronensis sp. nov. is in the group of species around N. cincta but has distinct outline, size, central area, and proximal raphe endings. The availability of data on the distribution of the new species in streams of the Island of Cyprus allowed to quantitatively compare the ecological preferences, niche position, and niche breadth of Navicula veronensis sp. nov. with those of allied species. The new species was found to be characteristic of medium-high conductivity freshwaters, rich in sulphates and chloride, often nitrate enriched and affected by marked discharge fluctuations and seasonal desiccation. Niche position however differed only slightly from those of morphologically-similar species, with the exception of Navicula dealpina that was found to be characteristic of oligotrophic, calciumbicarbonate rich environments with medium(-low) conductivity. Canonical Correspondence Analysis clearly showed that the most influential environmental variables determining the diatom assemblages of low-elevation carbonate springs affected by anthropogenic disturbance were nitrate enrichment, spring morphology alteration (in particular for water abstraction), and low discharge.
