“…Also, A. exiguum, G. parvulum, A. ovalis have been previously reported as thermophiles existing at 40-58°C(Quintela et al, 2013;Covarrubias et al, 2016). Moreover, A. exiguum has been recorded in all samples collected from the limnocrene springs of Bunica that are situated in the south of Bosnia and Herzegovina, and this species has been frequently found in many alkaline hot springs(DeDić et al, 2015).…”

Diatom diversity in some hot springs of northern Thailand

2018

Diversity of hot spring diatoms in northern Thailand was studied. Forty-six diatom species were identified in eight localities. The dominant species according to high relative abundance were Diatomella balfouriana (41.7%), Achnanthidium exiguum (20.9%) and Anomoeoneis sphaerophora (11.2%). Moreover, Caloneis molaris, Craticula acidoclinata, Navicula subrhynchocephala and Pinnularia saprophila were recorded as species new to Thailand. The NMDS ordination revealed variation in species composition of eight different hot springs and correlation with the existing environmental variables. Silicon dioxide (SiO2), pH, conductivity, water temperature and total hardness were statistically significant factors affecting relative abundance of Achnanthidium exiguum, Amphora montana, Caloneis aequatorialis, Cocconeis placentula, Craticula cuspidata, Diploneis elliptica, Gomphonema affine, Gomphonema augur, Halamphora fontinalis, Planothidium lanceolatum, Pinnularia abaujensis, Sellaphora lanceolata and Stauroneis anceps.

“…This karst is formed in Upper Jurassic calcareous rock, where Wojtal (2009) described 307 taxa from Kobylanka stream, while Kawecka (2012) found 414 species in 27 karst streams in the Tatra National Park. The karst springs diatom epilithic assemblages in Bosnia and Herzegovina were studied by Dedić et al (2015). Lai et al (2016) also noted epilithic diatom assemblages in a karst spring of Sardinia (Italy) and confirmed ecological potential of the karst features.…”

Many karstic streams are threatened both by anthropogenic and climate changes, but little is known about their algal biodiversity and conservation value, especially in the Slovak Karst. Diatom assemblages occurring on seven substrates, including stones, mud, submerged mosses and filamentous algae: Cladophora glomerata, Vaucheria sp., Ulothrix zonata, Spirogyra sp. in two nameless karstic streams in the Krásnohorská Dlhá Lúka Village and the Gombasek Cottage Settlement (the Slavec Village) in the Košice Region of central-eastern Slovakia (the Silická Plateau) were studied. A total of 124 diatom taxa were found at four sites, where epilithic and epiphytic diatom assemblages dominated. Both species' richness and Shannon-Wiener indices showed congruent biotic integrity. The dominant taxa were alkaliphilous, halophobous-oligohalobous, requiring xeno-oligosaprobic and oligotrophic waters. Diatoms include: Diploneis krammeri, Encyonema ventricosum, Gomphonema acuminatum, Gyrosigma attenuatum, Navicula tripunctata, and Paraplaconeis cracoviensis. The latter species is a new report for Slovakia, reflecting the calcareous, geological nature of the Silická Plateau (the Slovak Karst). Diatom assemblages in two karstic streams consisted mainly of small-celled species of Achnanthidium, Amphora, Caloneis, Planothidium, and Stauroneis. Our results showed that the diatom assemblages were mostly structured by environmental factors of calcium and pH gradients, confirmed by canonical variates analysis (CVA) and Monte Carlo permutation tests. However, unique spatial and biological gradients, specific to different guilds related to each other, were also evident. The Slovak karstic streams should be especially protected and regularly monitored.

“…glass) in a marine environment provide an opportunity to monitor the initial development and succession of diatoms in the periphyton (NENADOVIĆ et al, 2015;CAR et al, 2020). In contrast, DEDIĆ et al (2015) investigated artificial and natural substrates in a karstic spring and reported that artificial substrates include fewer diatom taxa. However, this might be related to the differences between marine and freshwater ecosystems, whereas generally marine environments provide a greater diatom biodiversity compared to freshwater ecosystems.…”

In this study, the diatoms of three alternative habitats (epilithon, epiphyton and artificial sub-strate) were compared to understand the differences in composition on artificial and natural sub-strates. For this purpose, the samples were collected weekly between 11th August and 2nd Septem-ber 2016 at a sampling site in a shallow marine lake, Mrtvo More (Dead Sea) on Lokrum Island near Dubrovnik (South Adriatic, Croatia). In addition to detailed light microscopic analysis, ultrastructural analysis of benthic diatoms from Lake Mrtvo More was performed for the first time using scanning electron microscopy (SEM). A total of 97 taxa were identified in 12 samples. Cocconeis scutellum Ehrenberg and Halamphora coffeiformis (C.Agardh) Levkov were the most frequent taxa in the samples. Shannon-Wiener diver-sity index (H’) values varied from 1.78 (in September on Padina sp.) to 4.52 (in August on glass). According to non-metric multidimensional scaling ordination, there were two groups: epilithon and artificial glass substrate as Group1 and macroalgae as Group2. The results of the analysis showed that the diatom communities developing on artificial sub-strates accurately correspond to the diatom community of a rock substrate and thus can be used as a representative alternative tool for studies of epilithic diatoms in further experiments.
