“…Corresponding author: danafidlerova@azet.sk diatoms proved to serve as valuable indicators also in standing waters in many European regions, especially with regard to eutrophication (Hofmann, 1994;King et al, 2000;Kitner and Poulíčková, 2003;Blanco et al, 2004;Poulíčková et al, 2004;Schaumburg et al, 2004;Ács et al, 2005;Stenger-Kovács et al, 2007;Jüttner et al, 2010;Novais et al, 2012;Bennion et al, 2014;Cantonati and Lowe, 2014;De Nicola and Kelly, 2014;Kelly et al, 2014a;Poulíčková et al, 2014). Despite their promising bioindicative potential in European lentic ecosystems, only a few countries have produced diatom-based WFD-compliant assessment systems for these habitats (Kelly, 2013) and there are very few studies focusing on the evaluation of ecological potential assessment of reservoirs based on benthic diatoms (Novais et al, 2012).…”

-The main objective of the present study is to describe the structure of benthic diatom communities in 23 water reservoirs in Slovakia classified as heavily modified water bodies. Environmental variables together with biological data obtained during the routine biomonitoring of water reservoirs in Slovakia were explored and analysed to understand variability of benthic diatom communities and their relationships with environmental variables in order to obtain an integrated knowledge about their relevance as bioindicators for the Water Framework Directive-compliant ecological potential assessment. This study summarizes results from a four-year monitoring programme of water reservoirs surveyed during the period of 2011-2014. The performed survey and statistical analyses revealed the following: (i) two main groups of reservoirs could be distinguished based on the purpose of their main use (multipurpose or drinking water-supply use); (ii) multipurpose and drinking water-supply reservoirs differed in benthic diatom community structure, diatom water quality indices as well as in the principal environmental gradients structuring the diatom communities; (iii) 5 distinct sub-groups of reservoirs could be identified differing in terms of diatom species composition and several environmental parameters; (iv) the most significant environmental variables in explaining differences in diatom species composition in multipurpose reservoirs were mean depth and mean annual flow; in drinking water-supply reservoirs conductivity and water transparency.Key-words: benthic diatom / phytobenthos / water reservoir / Slovakia / Water Framework Directive Résumé -Les relations entre la structure des assemblages de diatomées benthiques et certains paramètres environnementaux dans les réservoirs slovaques (Slovaquie, Europe). L'objectif principal de la présente étude est de décrire la structure des communautés de diatomées benthiques dans 23 réservoirs en Slovaquie classés comme masses d'eau fortement modifiées. Les variables environnementales ainsi que des données biologiques obtenues au cours de la biosurveillance de routine des réservoirs en Slovaquie ont été explorées et analysées afin de comprendre la variabilité des communautés de diatomées benthiques et leurs relations avec les variables environnementales et d'obtenir une connaissance intégrée sur leur pertinence comme bioindicateurs pour la directive cadre sur l'eau -conforme à l'évalua-tion du potentiel écologique. Cette étude résume les résultats d'un programme de suivi de quatre ans des réservoirs au cours de la période 2011-2014. Le suivi effectué et les analyses statistiques ont révélé : (i) deux principaux groupes de réservoirs peuvent être distingués en fonction du but de leur utilisation principale (polyvalente ou d'approvisionnement en eau potable) ; (ii) les réservoirs à usages multiples et d'alimentation en eau potable différaient dans la structure des communautés de diatomées benthiques, aussi bien les indices diatomée de qualité de l'eau, que les principaux gradien...

“…For instance, fine, freshwater sediments (epipelon) are known for very low sampling efforts (Poulíčková et al 2014), even though they are inhabited by a complex and diverse community of cyanobacteria and other algae (Mann et al 2008;Poulíčková et al 2008). Moreover, the sampling efforts of cyanobacteriologists are traditionally concentrated in temperate zones, although tropical latitudes may serve as hot spots of biodiversity (see Hohner-Divine et al 2004 for review).…”

Difference without distinction? Gaps in cyanobacterial systematics; when more is just too much

Cyanobacteria are amongst the most abundant, ubiquitous, ecologically and evolutionarily significant microbes on Earth. Unique among the Bacteria in their capacity to be identified using morphology, understanding the evolutionary relationships and describing the diversity of this lineage is both important and challenging. The advent of modern sequencing technology has proven a boon to those studying cyanobacterial systematics as it has provided copious amounts of sequence data (mainly of the 16S rRNA gene sequence). However, this influx of data has also led to taxonomic confusion and recognition of polyphyly in many genera. Thus, the purpose of this paper is to describe this apparent paradox of increasing data yet poor phylogenetic resolutions by employing the Poisson Tree Process (PTP) algorithm and to propose some ameliorative efforts.

“…Light and temperature significantly influence diatom abundance in different communities (Hill, 1996). Poulíčková et al (2014) stressed that epipelon distribution is affected primarily by the depth of the overlying water, light, temperature, and sediment type. The most influential factor in this investigation was water transparency, which is in accordance with Goldenberg et al (2014), who also pointed out the influence of particles that decrease transparency, and thus change the structure of diatom communities.…”
