Pozycja Open Access Zbiorowiska seminaturalne z rzędu Arrhenatheretalia klasy Molinio-Arrhenatheretea występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczeciniePhytocenoses of Arrhenatheretalia order are representative in the investigated area for 46 vegetation patches classified into the complex of Arrhenatheretum elatioris and into the community of Poa pratensis-Festuca rubra. Arrhenatheretum elatioris complex is most frequently found on warm and dry small slopes situated in different places of the studied area, on moderately compact soils of alkaline reaction. The most species in the complex are representative for Molinio-Arrhenatheretea class (32 taxa), and some of them, Poa pratensis and Festuca rubra, reach a facial form in some vegetation patches. The structure of Arrhenatheretum elatioris complex has a character of a temporary community referring to phytocenoses of Artemisietea vulgaris class, which is represented by 30 taxa, of which Urtica dioica and Chelidonium majus reach a rank of facies in a part of patches. The vegetation patches in which Arrhenatherum elatius occurs were classified into Poa pratensis-Festuca rubra community. It also settles down on exposed to the sun and dry slopes of small hills, but it is also found on flat sheltered areas. Like in the previous complex, in the structure of this community the species characteristic of Molinio-Arrhenatheretea (27 taxa) and Artemisietea vulgaris (24 taxa) class are dominating. The structure of both seminatural communities found mainly in meadow habitats has a temporary character in the investigated area. A considerable number of species from Molinio-Arrhenatheretea class is a result of the activity of human being who introduced into the investigated area organic soils taken from meadows, containing reproductive organs of these species.Pozycja Open Access Nitrofilne zbiorowiska segetalne i zrębów występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn the investigated area there are patches of segetal vegetation. They were defined as nitrophilous communities of Stellaria media. Species characteristic of Stellarietea mediae class are found in flower beds and also on the exposed and unsheltered surfaces formed by plant cultivation on these sites. These communities are floristically rich (112 taxa), and Stellaria media (S=V, D=870) is a dominating species. Apart from this nitrophilous taxon in the community structure there is a series of species of Molinio-Arrhenatheretea (26 taxa) and Artemisietea vulgaris (24 taxa). Communities of Stellaria media have the features of segetal plant communities, but its structure shows that they are undergoing a process of conversion leading to ruderal and seminatural communities. In the examined area there is also a floristically rich (102 taxa) complex of Calamagrostietum epigeji, typical of forest felling sites. Aside from a frequently found species of a characteristic complex of Calamagrostis epigejos (S=V, D=542), there are also numerous species of Artemisietea vulgaris (31 taxa) and Molinio- Arrhenatheretea (30 taxa) classes. Sparse species, characteristic of the latter syntaxon (Taraxacum officinale and Potentilla reptans) reach a facial form in some patches. Phytocenoses of Calamagrostietum epigeji complex settle down mainly in compact soils situated on small slopes adjacent to the inner roads of the area. They are also found on pavements and lawns.Pozycja Open Access Zespół Urtico-Aegopodietum podagrariae i zbiorowisko z Veronica chamaedrys występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowckiego i Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn the area of the former University of Agriculture situated in Słowackiego and Papieża Pawła VI streets there is a nitrophilous seminatural community of fringe type Urtico- Aegopodietum podagrariae, internally differentiated into a typical variant and a forest variant. The typical variant of community is constituted by patches situated on surfaces shadowed by the forest stand and shrubs occurring along Słowackiego Street. A series of species of forest communities can be found in them, but most often and most numerous, frequently in a facial form, Ficaria verna and Corydalis solida are found, more rarely – Adoxa moschatellina, Anemone nemorosa and Gagea lutea. Both in the typical variant and in the forest one, the characteristic species Aegopodium podagraria is dominating (S=V and in both variants it reaches D=2514 and 1895, respectively) and it is accompanied by Urtica dioica (S respectively=V and II and D=2168 and 466). The typical variant occurs most frequently in narrow streets in the neighbourhood of buildings and also along the paths and inner roads of the area. Similar habitats are settled by Veronica chamaedrys, which most often is found on surfaces exposed to the sun, on slopes, along paths and on lawns. It is a prevailing species in these patches (S=V, D=1025).Pozycja Open Access Zbiorowiska seminaturalne klasy Molinio-Arrhenatheretea (z rzędów Plantaginetalia majoris i Trifolio fragiferae- -Agrostietalia stoloniferae) występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe order of Plantaginetalia majoris represents 13 patches of vegetation in the examined area. They were classified into the complex of Lolio-Polygonetum arenastri. These phytocentoses occur along roads, paths and pavements and on trodden surfaces. They settle mainly in compact soils of alkaline reaction. In the complex two species Lolium perenne var. humile and Plantago major var. typica dominate. In a part of patches a facial form is reached by: Trifolium repens, Achillea millefolium and Ficaria verna. Within the order of Trifolio fragiferae- -Agrostietalia stoloniferae a community of Potentilla reptans was distinguished. The patches of this phytocenosis are mainly found on warm and exposed to the sun slopes, on thinned out lawns, along paths and roads. The dominating species in the complex is Potentilla reptans (S=V, D=2324), it is accompanied by numerous species of Molinio-Arrhenatheretea class (25 taxa). The largest reciprocal similarity is shown by ruderal communities formed in dry and warm habitats, and a slightly smaller similarity is observed in the case of meadow and bush complexes. The least similar in respect of floristic composition and phytocociological stability of species are complexes of Echio-Melilotetum i Onopordetum acanthii as compared to the communities of the forest variant of Urtico-Aegopodietum podagrariae and Lolio- Polygonetum arenastri.Pozycja Open Access Zbiorowiska ruderalne występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiegoi Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieRuderal communities were described on the basis of 71 phytosociologic records. In the studied area four kinds of communities were distinguished as complexes of: Artemisio- Tanacetetum vulgaris, Dauco-Picridetum hieracioidis, Echio-Melilotetum and Onopordetum acanthii. Most vegetation patches were classified into the first two complexes. These communities are richest floristically and the number of taxa within their range varies from 107 to 112. The nature of Artemisio-Tanacetetum vulgaris complex is determined by two characteristic species – Tanacetum vulgare (S=V, D=1445) and Artemisia vulgaris (S=V, D=517). Phytocenoses of this complex are mainly found in fallow areas which are an integral part of built-up areas. They settle down mainly in sands underlaid with loam and clays rich in calcium carbonate. They also occur in a built-up area, but species of meadow communities have a considerable contribution to their structure. They appeared in these communities because their reproductive organs were brought with organic soil for the reclamation of destroyed surfaces. This is confirmed by a numerous and frequent and sometimes facial presence of Potentilla reptans (S=V, D=1895). Patches of Dauco-Picridetum hieracioidis complex occur in the fallow area and on individual sites within the built-up areas. A prevailing species is Picris hieracioides (S=V, D=2657). In the fallow area, very warm and exposed to the sun, often defined as an island of heat, thermophilous and xerophilous species characteristic of Echio- Melilotetum complex with a dominating taxon Melilotus alba (S=V, D=2475) are frequently found. Some patches of this complex were classified into a variant of Calamagrostis epigejos. Also under similar ecological conditions, Onopordetum acanthii. complex occurs. In its patches the presence of two characteristic species of Anchusa officinalis (D=775) and Reseda lutea (D=404) is very often (S=V) observed. The patches of Onopordetum acanthii complex are floristically richest and the average number of species in the record is 38 taxa. In these phytocenoses, characteristic species of Onopordetalia acanthii order occur numerously.Pozycja Open Access Dendroflora i brioflora na obszarze byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn the area the following items of species were recorded: 100 species of dendroflora, including 45 species of trees, 5 shrubs and 4 climbing plants. The distribution of all the taxa is illustrated in diagram 1, and their characteristics and the description of biotope (mainly soil conditions) are shown in Table 1. Scarcely found in the area of Szczecin, but occurring in the investigated area are the following species: dawn redwood (Metasequoia glyptostroboides), Chinese witch hazel (Hamamelis mollis) and Daniella evodia (Euodia daniellii = Tetradium daniellii). Eucomia elm (Eucommia ulmoides) is the only specimen in Szczecin and it is located in the examined area in an inner road that runs between Słowackiego Street and the university car park. In this area there have also been found three sites of protected evergreen climbing English ivy (Hedera helix). Common horse chestnut population is numerous (10 individuals). For several years it has been attacked by horse chestnut leaf miner (Cameraria ohridella). Bryoflora is not very numerous – only 9 taxa of Bryophyta found in different habitats have been recorded.Pozycja Open Access Ocena zawartości tłuszczu i cholesterolu w mięsie samic oraz samców okonia (Perca fluviatilis L.) z jeziora Gopło(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Stanek, Magdalena; Dąbrowski, Janusz; Roślewska, Aleksandra; Janicki, Bogdan; Zakład Biochemii Środowiska, Wydział Hodowli i Biologii Zwierząt, Uniwersytet Technologiczno-Przyrodniczy w Bydgoszczy; Katedra Ekologii, Wydział Hodowli i Biologii Zwierząt, Uniwersytet Technologiczno-Przyrodniczy w Bydgoszczy; Zakład Biochemii Środowiska, Wydział Hodowli i Biologii Zwierząt, Uniwersytet Technologiczno-Przyrodniczy w Bydgoszczy; Zakład Biochemii Środowiska, Wydział Hodowli i Biologii Zwierząt, Uniwersytet Technologiczno-Przyrodniczy w BydgoszczyThe aim of the study was to compare fat and total cholesterol content in the muscles of females and males of perch (Perca fluviatilis L.) caught in fall and spring from Gopło Lake. Analyses were carried out on 10 females and 10 males in each season. Fat was extracted from meat with the skin using the procedure of Folch et al. (1957) and content of total cholesterol was determined by UV-VIS method according to Liebermann-Burchardt (StrzeŜek i Wołos 1997). Fat content was higher in the muscles of perch caught in fall, then in fish from spring. The mean value of fat in the meat of females and males caught in fall was 0,50 and 0,48%, respectively but differences were not statistically significant. There was no statistically significant differences in the mean value of fat in the meat of females (0,38%) and males (0,34%) caught in spring. The mean content of total cholesterol in muscles of females of perch caught from Gopło was higher in fall (67,11 mg 100 g-1), than in females from spring (47,76 mg 100 g-1), and this values differed statistically significant. Analysis indicated that there were no statistically significant differences in mean values of cholesterol in males from fall (45,93 mg 100 g-1) and in the muscles of males caught in spring (53,34 mg 100 g-1). The mean content of cholesterol in females was higher than in males and it was respectively 57,44 i 49,63 mg 100 g-1, and this values differed statistically significant.Pozycja Open Access Zbiorowisko z Betula pendula i Populus tremula w zadrzewieniach śródpolnych zachodniej części Pojezierza Drawskiego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Młynkowiak, Elżbieta; Kutyna, Ignacy; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn the midfield afforestations of western part of Drawskie Lakeland step out the birchpoplar coppices, and in within them phytocenosis with Betula pendula and Populus tremula (Agrostio-Populetum tremulae tipical form and poor form), which was characterized basing on 19 phytosociological records. Betula pendula is a reigning species in community, and Populus tremula codominating. The verruculous birch (Betula pendula) occurs almost exclusively in layer of stand, however the aspen poplar (Populus tremula) is present and numerous in all layers of community. The structure of community builds 129 species, within them the most of forest species from − Querco-Fagetea class (32 taxa). In herbaceous layer predominate species from Molinio-Arrhentheretea class (24 taxa), less species occurs is from Artemisietea vulgaris class (16 taxa). The essential element of community structure is presence of species from Epilobietea angustifolii class (11 taxa). They decide about physiognomy of phytocenosis, because part of them achieves IV and V stability degree and considerable covering (e.g. Betula pendula S=V, D=3803, Populus tremula S=IV, D=763). The considerable variety of species in community results from its openness on penetration of species from different neighbouring habitats. From arable lands penetrate synanthropic species, and from meadows seminatural. Community of Betula pendula and Populus tremula is in phaze of reconstruction process of secondary succession aiming the direction of climax stage achievement - forest phytocenosis.Pozycja Open Access Charakterystyka przyrodnicza obszaru byłej Akademii Rolniczej w Szczecinie położonego przy ulicach J. Słowackiego i Papieża Pawła VI oraz informacje o celu i metodach badań roślinności na tym obszarze(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kutyna, Ignacy; Nieczkowska, Małgorzata; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Ekologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe town is an area differentiated ecologically both in respect of biotope and biocenosis. The area of the former University of Agriculture situated in Słowackiego and Papieża Pawła VI streets is a specific ecological system. It has peculiar features of urban environment such as much warmer and drier microclimate, and the soils are significantly converted. The aim of numerous studies is to determine plant communities and make an inventory of the dendroflora and bryoflora in this area. For this purpose, 213 phytosociological records were taken in 2006 and 2007 and dendroflora and bryoflora were determined. The results of the studies will be presented in several publications. In the examined area 39 comprehensive samples of soil were taken from the depth of 0–25 cm. Their pH, the content of CaCO3 and their granulometric composition were determined. The characteristic features of most soils are alkaline reaction and a differentiated content of CaCO3. In the surface layer of a soil, light loamy sands, heavy loamy sand and light loam dominate. They contain a significant amount of soil skeleton (remains of building work). The investigated area is "an island of heat", as it is sheltered from all directions by dense afforestation and buildings. These microclimatic conditions are favourable to the development of thermophilous plant communities.
