Baryczka stream
Opis:: The Baryczka stream is a small (about 20 km long), left bank tributary of the River San (Podkarpackie Voivodeship). Studies on diversity of diatom communities using OMNIDIA software were conducted in 2010 and 2011. Diatomaceous indices IPS, GDI and TDI and Van Dam et al. classification system were used for water quality assessment. Planothidium lanceolatum, Cocconeis placentula var. lineata, Achnanthidium minutissimum var. minutissimum, Nitzschia linearis, Rhoicosphenia abbreviata, Navicula lanceolata and Naicula gregaria were the most numerous. Values of the IPS index indicate good water quality (II–III class). Based on the GDI index, waters of the Baryczka stream were classified to III class water quality. The TDI index indicated poor and bad ecological state on the most sampling sites. On all sampling sites alaliphilous (pH>7) diatoms taxa predominated. The most common were eutraphentic and hypereutraphentic diatoms. With respect to trophy, it was shown that α- and β-mesosaprobous diatoms were the most common (III and II class water quality).

Podkarpacie Region
Opis:: Diatoms Bacillariophyceae are a specialized, systematic group of algae, living in different types of ecosystems, and they are very good indicators of water quality. Recently, detailed studies have been carried out in the territory of the Podkarpacie Province on the diversity of diatoms in running waters. The area of study covers mostly the catchment of the biggest rivers of the province (mainly the Wisłok River) and cultivated soils. Running waters in the Podkarpacie Province are characterized by a huge species richness of diatoms, 738 different taxa have been found so far. The highest number of taxa was noted in the Wisłok River (400), while the Żołynianka and Różanka streams and the Mleczka were also characterized by huge diversity (from 200 to over 350 taxa). In the majority of studied sites diatoms of alkaline (pH>7) and nutrient rich (eutrophic) waters dominated: Navicula lanceolata, N. gregaria, N. capitatoradiata, Nitzschia palea, N. dissipata ssp. dissipata, Achnanthidium minutissimum var. minutissimum, A. pyrenaicum, Amphora pediculus, Diatoma vulgaris, Rhoicosphenia abbreviata, Planothidium lanceolatum, Cocconeis pediculus and C. placentula var. lineata. About 150 taxa were indentified on cultivated soils, among which the largest populations were formed by Hantzschia amphioxys, Mayamaea atomus, Nitzschia palea, N. pusilla, Pinnularia obscura and Stauroneis thermicola.

Tytuł:: Diversity of diatoms (bacillariophyceae) in the soil under traditional tillage and reduced tillage

Opis:: Research on soil diatoms has been conducted in Podkarpacie voivodeship in Dąbrowa village ( 50°03'31 N 21°48'35 E) in the Subcarpathian Province in SE Poland. On the same soil type, i.e. silty clay loam (sand 0-23%, silt >40, clay 36-50%), two tillage systems were applied under maize (Zea mays): traditional and reduced. The major aim of the research was to analyse diatom diversity depending on the applied tillage system under maize (Zea mays). In the soil samples it was identified 62 taxa of diatoms, including 38 under traditional tillage, and 50 under reduced tillage. Under traditional tillage the most frequent species were Stauroneis thermicola, Mayamaea cf. atomus var. permitis, Nitzschia palea, and Pinnularia obscura. Under reduced tillage, Amphora montana was the most abundant. The dominant diatoms are characteristic of water reservoirs but are regulary found also on wet or moist sites.
Badania nad okrzemkami glebowymi prowadzono na terenie woj. Podkarpackiego w miejscowości Dąbrowa ( 50°03'31 N 21°48'35 E), gdzie na tej samej glebie zastosowano dwa systemy uprawy roli tradycyjny i uproszczony. Celem pracy było zbadanie różnorodności okrzemek w zależności od zastosowanego systemu uprawy roli na tej samej glebie - pyle ilastym (płi) pod uprawą kukurydzy. W materiale oznaczono 62 taksony okrzemek, w tym w próbkach z uprawy tradycyjnej - 38, natomiast z uprawy uproszczonej - 50 taksonów. Na polu z uprawą tradycyjną dominowały: Stauroneis thermicola, Mayamaea cf. atomus var. permitis, Nitzschia palea i Pinnularia obscura, natomiast na polu z uprawą uproszczoną najliczniej rozwijała się Amphora montana. W obydwóch systemach uprawy dominowały okrzemki występujące głównie w zbiornikach wodnych, ale także regularnie na mokrych i wilgotnych miejscach.

Wisłok river
Opis:: Research conducted in 2007–2008 on eight sites designated along the Wisłok River showed great diatoms diversity – indicated a total of 401 diatom taxa. Achnathidium pyrenaicum, A. minutissimum var. minutissimum, Navicula gregaria, N. lanceolata, Amphora pediculus, Cyclotella meneghiniana, Gomphonema olivaceum var. olivaceum, Nitzschia dissipata ssp. dissipata were most frequent. Based on diatomaceous indices IPS, GDI and TDI has been shown that the upper part of Wisłok had a high and good ecological status. However, the middle and lower section of river was characterized by moderate and poor ecological status, on the base of the IPS and GDI indices (III and IV class). TDI value indicated bad water quality (V class) in the middle and lower section.

Opis:: The studies on bentic diatoms were conducted in 2009–2011 at eight samplings sites over the Żołynianka stream and its tributary, the Jagielnia. 427 diatom taxa were recorded in total. Achnanthidium minutissimum var. minutissimum, Aulacoseira ambigua, Fragilaria capucina var. capucina, Gomphonema parvlum, Navicula gregaria, Nitzschia palea and Planothidium lanceolatum were dominant taxa in both watercourses. Chemical analysis of water showed high chemical status of water at most of sampling sites. The results of diatomaceous analysis conducted with OMNIDIA software revealed moderate and poor condition of water. The best water quality was recorded in the Jagielnia stream (good or moderate status). The values of the analyzed indices showed the worst water quality on the Żołynianka at site four, showing bad ecological status. TDI index deviated the most from the other two indices (IPS and GDI), always indicating poorer water quality.
