“…The species developed in oligotrophic conditions in the upper, shaded parts of small streams with a rapid current, and among mosses. Placogeia gereckei was reported by Cantonati and Lange-Bertalot [57] and Vidakovic et al [61] under similar conditions. As the species usually develops in the upper reaches of streams or sources, it may be a good indicator species for unpolluted, oligotrophic waters.…”

“…The species occurred under oligotrophic conditions, where the pH was alkaline (8.0) and conductivity was low [57]. The species was later reported several times from sources in the Alps [58][59][60], and recently in Serbia in two small mountain rivers, in the epilithon and epibryon [61]. The species developed in oligotrophic conditions in the upper, shaded parts of small streams with a rapid current, and among mosses.…”

Valuable habitats of protected areas in southern Poland – a source of rare and poorly known diatom species

The peatbogs and natural upper sections of streams in national parks in southeastern Poland represent unique study areas for research on freshwater diatom diversity. During studies conducted on diatoms in three Polish national parks, many little-known, very rare, and endangered species were noted. For most of the taxa presented in this article, especially from the Adlafia, Eunotia, and Placogeia genera, only single individuals have been observed, and only from a few localities worldwide. Moreover, this is the first presentation of SEM photodocumentation and descriptions for Eunotia minutula Grunow and Fallacia sublucidula (Hustedt) D. G. Mann. Based on both light and scanning electron microscopy, detailed descriptions of morphological characteristics, ecological notes, and new localities are presented for the following species: Adlafia langebertalotii Monnier

“…Spring areas often contain significant biodiversity values, including a diverse mixture of cosmopolitan and endemic flora and fauna (Vidakovic et al 2017;Puczko et al 2018;Wojtal 2013). The springs studied differed in their richness of organisms, which is associated with varying degrees of human transformation, the physical and chemical parameters of water, the diversity of bottom substrates, their stability and availability of food resources (Kwiatkowska et al 2016).…”

Hyporheic zone (HZ) is an interstitial part of groundwater. Complex physical, chemical and biological processes in HZ impact water quality. We hypothesized that groundwater upwelling improves surface water with biogenic compounds in lowland spring niches, and it depends on among others biota communities. The research was conducted in two spring niches in suburbs of Białystok. Interstitial samples were collected with mini-piezometers. In the field, the physical parameters of water were examined, and the micro and macro elements were determined in the laboratory. The analysis of biota included: vascular plants and bryophytes, diatoms, macroinvertebrates and bacteria. The springs studied differed in their richness of organisms, which is associated with varying degrees of abiotic conditions and human transformation. In spring niche with high degree of naturalness were twice less nitrate ions in the surface water than in interstitial water, which indicates the assimilation of nitrate ions by plants growing on the bottom of the niche. Hydrophilic vegetation performs a stabilizing function by assimilating nitrogen compounds and contributing to a variation in nutrients concentration. Groundwater upwelling enrich surface water with DOC and TON. In spring niche No.1 with patches of vegetation, the largest number of macrozoobenthos was recorded. While, the heterogeneous bottom of spring niche No.2 affected the diversity of habitats, and greater biodiversity of benthic fauna. In interstitial waters, there were about twice as few bacteria as in spring waters. Psychrophilic bacteria were present in interstitial waters that influence natural hyporheic processes including circulation of organic matter in the microbiological loop and self-purification of water.

A total of 15 Navicula taxa were recorded in epilithic communities occurring in seven rivers of Serbia, all of which are new to the diatom flora of Serbia. The most interesting of them are N. splendicula and N. moskalii. When observing N. splendicula specimens under SEM, we noticed a characteristic silicate tongue in the center of raphe ends, which had not been previously reported in the available literature. The insufficiently researched distribution of N. moskalii and scarce autecological information on the taxon prompted us to provide new details about the species in this study. These findings clearly indicate the need for further comprehensive research that would provide new information on rare taxa.
