At four established sites, biological samples were taken for analyses. In total, 44 taxa of zooplankton were determiend in the collected material. The upper section of the Wkra River, along which two sites were set up, was in general more varied in species composition, and the structure of biocenosis was shaped by rotifers and protozoa (mainly ameba species) in nearly equal halves. At the other two sampling sites, localized below, along a further section of the watercourse, the structure of zooplankton was poorer. It was colonized by larger numbers of individuals belonging to a few species of rotifers, among which Keratella cochlearis var. tecta, Trichocerca similis and T. pusilla are the species indicating a raised level of the trophy of the river water.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"25 1","pages":"387-400"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68932289","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}

After hypophysation eggs were obtained from a similar percentage (~85%) of fish in both strains while after the Ovopel treatment from 100% of females in strain 0 and 50% in strain J. Interaction between the preparation and the provenance of the fish was statistically significant (P ≤ 0.05) for the weight of eggs (in grams and in percentage of female body weight). The highest weight of eggs was obtained after Ovopel treatment of females of strain J and the lowest after CPH application to fish of the same strain (1042.98 g, 15.60% and 746.49 g, 10.97%, respectively). The statistical significance (P ≤ 0.01) of the interaction was noted too for the fertilization percentage; the lowest quality characterized eggs obtained from females of strain J treated with CPH and the highest for eggs of the same strain treated with Ovopel (95.80% and 98.20%, respectively). The effect of latency as an important factor of quality of the eggs obtained after ovulation induction with CPH and with Ovopel from females of the strain 0 was determined. The comparison of reproduction effects of the investigated breeding strains of carp showed that these strains differently respond to the ovulation stimulators applied.

In addition, the results of the study are a contribution to a comparative analysis of methods for macrophyte evaluation of watercourses used in Poland and to identify the possibilities of their application in investigations of artificial watercourses under the pressure of pesticides. Values of indices of the hydromorphological evaluation (HQA, HMS) were similar for all drainage ditches examined. This points to a negligible effect of the pesticide tomb on the hydromorphological characteristics of the analyzed watercourses. The pesticide tomb was found to affect the ecological status and floral diversity of the drainage ditches. The lowest values of macrophyte and diversity indices were recorded in the first and the second watercourse, whereas higher ones were in the third watercourse. Changes in the indices of ecological status and those of floral diversity observed in the watercourses examined show that the effect of the pesticide tomb on the surrounding ecosystem is consistent with topographic features and proceeds in a north-easterly direction. Both methods of the macrophyte evaluation of the ecological status of watercourses (MTR, MIR) yield different numeric values, yet their results are comparable in terms of the tendency of changes in the ecological status of the analyzed watercourses. In both methods, the highest rank was reported for the third watercourse. The MTR index diversifies the examined watercourses to a smaller extent than the MIR index. The MIR method is better under conditions of lowland Poland for the evaluation of the ecological status of artificial watercourses, as it enables stronger diversification of the ecological status of the watercourses examined due to a higher number of indicatory species.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"25 1","pages":"259-271"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68932126","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}

An exact, two-factorial field experiment was conducted by the randomized split-plot method, in four replications, in the years 2004–2006 in the Masurian Lakeland. The total yield of potato tubers, the content and yield of starch, and the grain size fractions of starch were determined in the study. The applied fertilizers, regardless of their rates, had no significant effect on the total yield of potato tubers and starch yield. The starch content of potatoes was affected by soil fertilization. An increase in the rate of mineral fertilizers from 280 to 420 kg NPK ha –1 caused a decrease in starch content. Large starch grains (> 40 μm in diameter), which enable to reduce the overall loss during the removal of starch from the potato pulp, dominated in the experimental material.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"25 1","pages":"215-228"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68931978","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}
