Biscay Bay
Opis:
This study describes the phytoplankton community in sheltered euhaline waters of the Basque coast (southeastern Bay of Biscay). Phytoplankton composition, cell size, abundance, biomass and the presence of potentially toxic taxa, together with chlorophyll a, nutrients and hydrographic and optical conditions were measured, from August 2016 to August 2017, in the Mutriku port, with the main aim of assessing the suitability of the phytoplankton community as a food resource for bivalves. The water column in Mutriku showed the typical environmental conditions of Basque marine waters, with no significant nutrient enrichment caused by anthropogenic pressures. Haptophytes represented the greatest contribution to cell abundance (31—47%), and diatoms were the dominant group in terms of biomass (52—79%), which could favour mussel growth due to their high fatty acid content. In addition, the size structure of the phytoplankton community was suitable for mussel ingestion, since the predominant cell size was 2—20 μm. Regarding toxic phytoplankton, the genera that pose a risk for human health and those that affect negatively mussel physiology and survival were considered. Altogether, ten toxic phytoplankton taxa were identified, contributing in less than 5% to the total cell abundance of Mutriku. However, median chlorophyll a concentration was low (0.5 μg L−1), reflecting the oligotrophic conditions of the area. Therefore, even if the composition of the phytoplankton community could be favourable for bivalve aquaculture, biomass values are low compared to other zones of bivalve production.

Opis:
The species composition and size-structure of the phytoplankton community in the Boka Kotorska Bay (SE Adriatic Sea) were analysed with respect to abundance and carbon biomass, together with the physico-chemical parameters, with the aim of evaluating the predefined oligo-mesotrophic status of this transitional water ecosystem. Three stations located in the inner part of the Bay were sampled with seasonal frequency in 2008/2009. Picophytoplankton cells were counted using flow cytometry; nanophytoplankton and microphytoplankton were identified and counted by light microscopy. The relative importance of the picoplankton in the Bay, in terms of both abundance and biomass, during all the investigated seasons emphasized their significance in the phytoplankton community. Picocyanobacteria (Synechococcus) constituted a significant part of the summer assemblages with regard to both abundance (up to 3.38 × 108 cells L−1) and carbon biomass (up to 73% of total phytoplankton carbon). The contribution of the nanophytoplankton was found to be generally low (<20% of the total phytoplankton carbon) in all seasons, and was dominated by autotrophic/mixotrophic flagellates. Species with a preference towards nutrient-enriched conditions, like the diatom Skeletonema marinoi, dominated the microphytoplankton fraction. S. marinoi was the most abundant in spring/winter (up to 2.86×106 cells L−1) above the halocline (making a 96% contribution to the microphytoplankton). The potentially toxin-producing diatom Pseudo-nitzschia pseudodelicatissima was recorded at abundances greater than 105 cells L−1, together with Thalassionema frauenfeldii, as well as the dinoflagellates Prorocentrum micans and the potentially harmful P. minimum. The higher values of phytoplankton biomass and the dominance of phytoplankton species or groups with preferences for nutrient-enriched conditions appear to be consistent with the oligo-mesotrophic status of this specific ecosystem.

Opis:
Studies considering hummocks and hollows structure of bog forests were carried out in the Stare Biele Reserve in the Knyszyn Forest. The aim of the study was better recognition of bog forests spatial structure including recognition of soil chemical composition of hummocks and hollows. The bog forest communities in Stare Biele Reserve have various percentage of hummocks. The hummocks have similar morphological structure and are distinctly separated from hollows in all four bog forest communities. Degree of hummocks development and their morphological structure have big impact on plant distribution on their surface. Soil chemical properties are one of the factors, which influence floral abundance and composition of microcenoses. Soil reaction and calcium content, among other measured properties, exert the biggest influence on the floral abundance and composition of microcenoses.

Opis:
Couch grass (Agropyron repens L.) was the dominantspecies in 5 investigated communities with stability class5, while its share in the community Agropyron repens + Festucarubra was as high as 42.2%. Communities with the dominanceof Agropyron repens + Deschampsia caespitosa and Agropyronrepens + Avenula pubescens represent the greatest variety of theirconstituent species, a total of 43 vascular plant species from15 botanical families having been recorded and 7 accompanyingspeciens. Due to the advantageous floristic composition and thefodder value score FVS of 6 or even higher, most analyzed communitiesare of considerable fodder value, although the value ofthe sward is reduced by taxa of low nutritive value and of lowyielding potential. Semi-heliophilous plant species are dominantin that community, occupying partially dry, fresh and even moisthabitats indicating acid soils with a high content of nitrogen compounds(N = 6.6). In Polish literature there is no synthetic study ofa community with the dominance of true wheat grass Agropyronrepens (L.) P.Beauv. that would focus on floristic composition,yield as well as natural and production value.

Mycorrhizal fungi influence the development and activity of communities of soil microorganisms. The purpose of this study was to estimate the effect of arbuscular mycorrhizal fungus Claroideoglomus etunicatum (W. N. Becker & Gerd.) C. Walker & Schüβler on the population structure of fungal colonies in the rhizosphere of tomatoes grown in a plastic tunnel. The field experiment was conducted from 2015 to 2017 at an ecological farm in Grądy, central eastern Poland. The object of study were the three tomato cultivars: ‘Antalya F 1 ’, ‘Esmira F 1 ’, and ‘Pelikan F 1 ’. Tomato seedlings were inoculated with C. etunicatum; spores were introduced about 5 cm deep in the rhizosphere of the studied plants (25–30 spores of C. etunicatum for each plant). Each year, mycological analysis of the tomato rhizosphere was conducted using Warcup’s method; structure of fungal communities of the tomato rhizosphere varied depending on the AMF applied. Saprotrophic fungi such as Trichoderma ssp., Mucor spp., and Penicillium spp. were often more isolated from the rhizosphere of plants inoculated with C. etunicatum than that of the control samples. It can be concluded that AMF directly impacted the development of fungal biodiversity in the tomato rhizosphere, particularly regarding the number of saprotrophs in the soil.

Opis:
A Scots pine forest, affected by the great cormorant colony, was studied by plot-based fungal survey method during the years 2010-2012 in Lithuania. Diversity and composition of fungal communities were investigated at five zones that had been influenced by different stages of breeding colony establishment: starting-point and almost abandoned cormorant colony part (zones A and B), active part (zones C and D), and the edge of the colony (zone E). The control zone G in undamaged by cormorants pine stand was assessed too. A total of 257 fungal species of ascomycetes including anamorphic fungi, basidiomycetes and zygomycetes were recorded. Seven species were registered for the first time in Lithuania. Species richness in the examined zones varied, lowest being in zones B (51 species), C (46) and D (73) and almost twice as high in the zones A and E (129 and 120, respectively). The comparison of fungal species compositions of different zones showed that their similarity was rather low (SS: 0.22–0.59). The most obvious changes in the trophic structure of fungal communities in the territory occupied by the bird colony were a strong decrease of mycorrhizal species, the presence of coprophilous fungi on forest litter, and the appearance of host-specialized fungi on alien and non-forest plants that have established in the disturbed forest.

Opis:
The research was conducted on four patches of thermophilous oak wood in Białowieża Primeval Forest: A – with a woodstand: oak + approx. 30-year-old hornbeam + hornbeam brushwood; B – with a hornbeam stand formed by natural seed fall after logging (ca. 1920) oaks; C – after logging oaks and replanted (ca. 1965) with pine and oak; D – with a natural low-density oak stand. Species composition and seed bank density were estimated using the seedling emergence method. Seedling emergence was observed over two vegetation seasons. Research demonstrated that: 1) the species abundance of the seed banks depends on canopy cover (A, B approx. 50 species; C, D approx. 70 species); 2) the floristical similarity (Sørensen’s index) of the seed bank and ground vegetation is higher in the undisturbed patch D (0.50) than in disturbed patches (0.30-0.35); 3) species diversity in plots A, B, C, D (H’=12.5; 13.4; 15.5; 16.9) and seed bank density per m2 (432.5; 958.0; 1486.5; 2268.0) are negatively correlated with the degree of patch shading; 4) the average weight of diaspores in the seed banks of shady plots is lower (A, B approx. 0.003 g) than that of sunny plots (C, D approx. 0.08 g); 5) the share of long-lived diaspores increases in patches after logging.

Badania przeprowadzono w Cedyńskim Parku Krajobrazowym na madach odznaczających się silnie kwaśnym i kwaśnym odczynem (pH KCl od 4,1 do 4,8), dobrą zasobnością magnezu, a małą - przyswajalnego fosforu i potasu. Analizą objęto 16 zbiorowisk roślinnych, występujących w zróżnicowanych warunkach siedliskowych. Na madzie ciężkiej całkowitej ukształtowały się głównie zbiorowiska wyczyńcowe, np.: Alopecurus pratensis z Poa pratensis, Alopecurus pratensis z Phalaris arundinacea, Alopecurus pratensis z Poa trivialis, Deschampsia caespitosa z Alopecurus pratensis, także na tej samej madzie ciężkiej, ale płytkiej na piasku występowały: Poa pratensis z Arrhenatherum elatius, Poa pratensis z Festuca rubra,Arrhenatherum elatius z Bromus inermis. Na madzie średniej występowały Festuca rubra z Poa pratensis oraz Poa pratensis z Festuca rubra, a na madzie lekkiej Festuca rubra, Achillea ptarmica, Bromus tectorum, Trifolium arvense, Poa pratensis z Festuca rubra oraz Calamagrostis epigeios. Do gatunków powszechnie występujących na analizowanych madach były: z traw - wyczyniec łąkowy (Alopecurus pratensis L.) i wiechlina łąkowa (Poa pratensis L.), z motylkowatych - groszek łąkowy (Lathyrus pratensis L.), wyka ptasia (Vicia cracca, L.), natomiast z innych roślin dwuliściennych: rogownica pospolita (Cerastium holosteoides L.), ostrożeń polny (Cirsium arvense L.), jaskier rozłogowy (Ranunculus repens L.) i żywokost lekarski (Symphytum officinale L.). Wartość gospodarcza runi zbiorowisk, oceniona za pomocą Lwu, wynosiła średnio od 1,30 (wartość uboga) dla zbiorowiska Calamagrostis epigeios na madzie lekkiej do 7,52 (wartość dobra) dla zbiorowiska typu Poa pratensis z Festuca rubra na madzie ciężkiej. Badane łąki były interesujące krajobrazowo z powodu dużego zróżnicowania florystycznego, a na podstawie obliczonego średniego wskaźnika waloryzacji przyrodniczej, wynoszącego 2,3, badany użytek zielony można zakwalifikować do obszarów o umiarkowanych walorach przyrodniczych.
The study was carried out on the Cedynia Landscape Park Polder, on alluvial soil of pH(KCl) 4.1 - 4.8, abundant in Mg, but poor in available P and K. Sixteen plant communities which grew in various environmental conditions were analysed. Heavy alluvial soil were dominated by Alopecurus communities composed of Alopecurus pratensis with Poa pratensis, Alopecurus pratensis with Phalaris arundinacea, Alopecurus pratensis with Poa trivialis, Deschamsia caespitosa with Alopecurus pratensis. On the same but shallower soil on sandy substratum we found: Poa pratensis with Arrhenatherum elatius, Poa pratensis with Festuca rubra, Arrhenatherum elatius with Bromus inermis. Medium alluvial soil was overgrown by Festuca rubra with Poa pratensis and Poa pratensis with Festucarubra and light alluvial soil - by Festuca rubra, Achillea ptarmica, Bromus tectorum, Trifolium arvense, Poa pratensis with Festuca rubra and Calamagrostis epigeios. Species common on the analysed area included the grasses Alopecurus pratensis and Poa pratensis, the papilionaceous plants: Lathyrus pratensis and Vicia cracca and other dicotyledons: Cerastium vulgatum, Cirsium arvense, Ranunculus repens and Symphytum officinale. The economical value of the sward assessed by the sward value number method was from 1.30 on the average (poor) for the Calamagrostis epigeios community on light alluvial soil to 7.52 (good) for Poa pratensis with Festucarubra on heavy alluvial soil. Analysed meadows were interesting because of their floristic composition and their average valorisation index (2.3) classified that grassland to areas of moderate natural value.

Opis:
The studies were carried out on common reed (Phragmites australis) growing on the shores of Lake Glinno and forming rush communities of the alliance Phragmition. 10 plants with disease symptoms were gathered from each of five sites. The isolation and marking of pathogens were performed twice from fragments of leaf and blade tissues with disease symptoms. First, directly after collecting the plants incubated in sterile humid chambers and microorganism cultures on CDA and PDA medium, and then phytopathogen and saprotroph species occurring on dried green material were identified for 2-A months. The occurrence of 31 species of microscopic fungi overall was observed on the leaves, blades and inflorescences of P. australis, including 2 mycelia of Mycelia sterilia. The most frequently occurring species, present at all sites of Phragmites australis are: Alternaria alternata, Cladosporium cladosporioides, C. herbarum, Doratomyces stemonitis and Puccinia phragmitis, P. magnussiana and two mycelia of Mycelia sterilia. The most common species occurring on blades and inside them are: Acremoniella atra, Acremonium alternatum and Fusarium sambucinum. Sporadically, Ustilago grandis was also observed inside blades. Tiny necrotic stains on leaves and blades were caused by the presence of three species of the genus Leptoshaeria: L. culmifraga, L. eustoma and L. fuckelli. The occurrence of the sclerote of Claviceps microcephala was found in inflorescences.
Badania prowadzono na trzcinie pospolitej (Phragmites australis) porastającej brzegi wokół jeziora Glinno (woj. zachodniopomorskie) i tworzącej zbiorowiska szuwarowe ze związku Phragmition. Z pięciu stanowisk zbierano po 10 roślin z objawami chorobowymi. Izolację i oznaczanie patogenów wykonano dwukrotnie z fragmentów tkanek liści i źdźbeł z symptomami chorobowymi. Najpierw bezpośrednio po zbiorze roślin inkubowanych w sterylnych wilgotnych kamerach i hodowli mikroorganizmów na podłożach CDA i PDA, a następnie przez 2-4 miesiące identyfikowano gatunki fitopatogenów i saprotrofów pojawiające się na ususzonym materiale zielnikowym. Na liściach, źdźbłach i kwiatostanach P. australis stwierdzono łącznie występowanie 31. gatunków grzybów mikroskopowych, w tym dwóch grzybni Agonomycetes (Mycelia sterilia). Najczęściej występującymi gatunkami, obecnymi na wszystkich stanowiskach P. australis są: Alternaria alternata, Cladosporium cladosporioides, C. herbarum, Doratomyces stemonitis oraz Puccinia phragmitis, P. magnussiana i dwie grzybnie Mycelia sterilia. Na źdźbłach oraz w ich wnętrzu najpowszechniej występującymi gatunkami są: Acremoniella atra, Acremonium alternatum i Fusarium sambucinum. Sporadycznie zanotowano także obecność Ustilago grandis we wnętrzu źdźbeł. Drobne nekrotyczne plamistości na liściach i źdźbłach spowodowała obecność trzech gatunków rodzaju Leptoshaeria: L. culmifraga, L. eustoma oraz L. fuckelli. W kwiatostanach stwierdzono obecność sklerocjów Claviceps microcephala.

Opis:
A study was carried out in a shallow, eutrophic Oświn Lake, within Seven Islands Reserve (north-eastern Poland), in order to determine the infection of fish with monogeneans as sensitive indicators of water quality. This paper presents comparative analysis of the occurrence of Monogenea in fishes from two, distinctly separated pools of the lake, differing in environmental conditions. The impact of fish size and sampling season on the infection parameters was also analyzed. Material and methods. In 1998 and 1999, a total of 1091 fish representing 8 dominant species were examined. Samples were collected four times a year (in May, July, August, and October) simultaneously from the eastern and western parts of the lake. Results. 16 species of Monogenea (and some unidentified specimeus) occurred in the fish examined, most of them from the Dactylogyridae family: Dactylogyrus sphyrna, D. auriculatus, D. intermedius, D. anchoratus, D. falcatus, D. tincae, D. wunderi, D. zandti, D. difformis, D. nanus, D. distinguendus, D. crucifer, D. caballeroi. Furthermore, Tetraonchus monenteron (Tetraonchidae), Gyrodactylus elegans (Gyrodactylidae), and Paradiplozoon megan (Diplozoidae) were detected. Monogenea occurred abundantly on the gills of pike, roach, rudd, white bream, carp bream and crucian carp, but rather sporadically in tench and perch. The highest species variety and diversity of monogenean guilds were detected in carp bream and roach. It was proved that D. crucifer and D. difformis were significantly more abundant in the western pool compared to the eastern one. Infection of fish with Dactylogyridae was season-dependent, contrary to the infection of pike with T. monenteron. Intensity of infection of white bream with D. sphyrna and roach with D. crucifer increased with fish body length; such a relationship did not appear for the other monogeneans and their hosts. Conclusion. Presence of common Monogenea in the fish examined, lack of rare species, poor diversity of monogenean guilds and relatively low infection rate could be connected with the low stability of the lake environment. Location-dependent occurrence of D. crucifer and D. difformis indicated that the exchange between fish groups from the eastern and western parts of the lake is limited.

Opis:
A study was carried out in a shallow, eutrophic Oświn Lake, within Seven Islands Reserve (north-eastern Poland), in order to determine the infection of fish with monogeneans as sensitive indicators of water quality. This paper presents comparative analysis of the occurrence of Monogenea in fishes from two, distinctly separated pools of the lake, differing in environmental conditions. The impact of fish size and sampling season on the infection parameters was also analyzed. Material and methods. In 1998 and 1999, a total of 1091 fish representing 8 dominant species were examined. Samples were collected four times a year (in May, July, August, and October) simultaneously from the eastern and western parts of the lake. Results. 16 species of Monogenea (and some unidentified specimeus) occurred in the fish examined, most of them from the Dactylogyridae family: Dactylogyrus sphyrna, D. auriculatus, D. intermedius, D. anchoratus, D. falcatus, D. tincae, D. wunderi, D. zandti, D. difformis, D. nanus, D. distinguendus, D. crucifer, D. caballeroi. Furthermore, Tetraonchus monenteron (Tetraonchidae), Gyrodactylus elegans (Gyrodactylidae), and Paradiplozoon megan (Diplozoidae) were detected. Monogenea occurred abundantly on the gills of pike, roach, rudd, white bream, carp bream and crucian carp, but rather sporadically in tench and perch. The highest species variety and diversity of monogenean guilds were detected in carp bream and roach. It was proved that D. crucifer and D. difformis were significantly more abundant in the western pool compared to the eastern one. Infection of fish with Dactylogyridae was season-dependent, contrary to the infection of pike with T. monenteron. Intensity of infection of white bream with D. sphyrna and roach with D. crucifer increased with fish body length; such a relationship did not appear for the other monogeneans and their hosts. Conclusion. Presence of common Monogenea in the fish examined, lack of rare species, poor diversity of monogenean guilds and relatively low infection rate could be connected with the low stability of the lake environment. Location-dependent occurrence of D. crucifer and D. difformis indicated that the exchange between fish groups from the eastern and western parts of the lake is limited.
