The aim of the present work conducted in the area of Międzyrzeki Strict Nature Reserve in the Roztocze National Park was to show new sites of rare and species new to Poland from the Kobayasiella genus (K. okadae (Skvortzov) Lange-Bert., K. tintinnus Buczkó, Wojtal & Jahn) with regard to morphological and ecological characteristics. Chemical parameters show that investigated habitats are poor and oligotrophic with a low content of chlorides, sulfates and nitrates. K. okadae, K. subtilissima (Cleve) Lange-Bert. and K. tintinnus were found in the studied area. The authors suggest the use of synonym Navicula hoeflerii Cholnoky for the Kobayasiella okadae. LM and SEM images were used in the analysis of the material.

The studies were conducted on watercourses flowing out of raised peat bog areas in Orawsko-Nowotarska Basin and raised peat bogs and transitional moor in „Międzyrzeki” Reserve on the territory of the Roztocze National Park. New localities where Neidium hercynicum occurred were found on the peatland areas of Southern Poland (Orawsko-Nowotarska Basin) and South-eastern (the Roztocze National Park) during the studies conducted on Jamów, Tokarka and Chyżny streams and on the territory of “Międzyrzeki” Reserve between 2007–2013. Longer and wider specimens were found on both investigated sites in comparison to the dimensions listed in the Krammer and Lange-Bertalot key. N. hercynicum were always found as individual specimens.

Nowadays Didymosphenia geminata is one of the most frequently studied diatoms in the world, due to its massive development in most continents. In Poland, up to the 1990’s only a small number of specimens were recorded, from streams in the Tatra Mountains and the Dunajec River. D. geminata was found in 2007–2008 in the middle and upper sections of the Wisłok River, while in 2009 and 2011 it was also found in the Wisłoka, Ropa, Bielcza and San. The cells belonged to one morphotype “geminata” and were characterized by high variability of size. It develops in mesotrophic, well-oxygenated, upper parts of flowing waters with rapid currents. It was most abundant below reservoirs on the San, Wisłok and Wisłoka.

Water of the San River was characterized by good and high ecological status and high diatom richness. During four studied seasons at two sites 353 diatom taxa were identified in total, from which the most numerous were Achnathidium pyrenaicum (Hust.) Kobayasi and Achnanthidium minutissimum (Kütz.) Czarnecki var. minutis-simum. Water of the San River, was characterized by high and good water quality (II and I class) in all seasons and at both studied sites.

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.

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.

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).
