Species diversity in plant communities, measured by the Shannon-Wiener index, was found to depend on soil type, land use type and phytosociological affiliation. Greater species diversity was observed in communities that developed on mineral soils, are used as pastures, and belong to the class Molinio-Arrhenetheretea. The biodiversity of grassland communities on the Popielno Peninsula is affected by habitat conditions. The relationship between vegetation biodiversity and habitat quality is difficult to grasp due to its multidimensional character. The methods of multivariate statistics may prove useful in this respect.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"49 4 1","pages":"43-59"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68931418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relation between the abundance and biomass of green algae and selected physiochemical water parameters, species diversity and dominants in the total abundance and biomass of green algae were analyzed. The statistically significant relationships was noted between water temperature, oxygen content, total nitrogen and the biomass of green algae at the coefficient of multiple correlation R = 0.4722. Increased the abundance and biomass of green algae were followed by a decrease in water temperature and increase in oxygen content and total nitrogen concentration during their growth in a temperature range of 10.0oC to 18.8oC. The maximum biomass of green algae was noted in September and the maximum their abundance in October at the highest total nitrogen concentration. In the case of abundance, dominated taxa typical of plankton (Micratinium pusillum, Chlamydomonas spp., Golenkinia radiata, Golenkiniopsis sp., Koliella variabilis and Monoraphidium concortum) and biomass one – filamentous forms as a component of plant periphyton (Spirogyra sp., Stigeoclonium sp. and Ulothrix tenuissima).

The experiment continued for 20 days and it was conducted from hatching of the larvae. The initial density of fish during rearing was 1000 individuals dm –3 . Rearing water temperature was set at 12oC. The parameters such as: average body length and height of the larvae and survival after completion of rearing period, were recorded. The Artemia nauplii proved the most suitable for feeding burbot larvae during the initial rearing. Additionally, high mortality of larvae was recorded during the period of filling the swim bladder.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"24 1","pages":"76-84"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68931437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
