COENOLOGICAL INTEGRATION OF SAPONARIA PUMILIO FROM IEZER-PĂPUŞA MOUNTAINS

Saponaria pumilio is an alpine, herbaceous species from Caryophyllaceae family. It occurs dispersed in Eastern Alps and Romanian Carpathians (Iezer-Păpuşa and Făgăraş Massif). It was integrated in Potentillo chrysocraspedae–Festucetum airoidis association, class Juncetea trifidi KLIKA et HADAC 1944, order Caricetalia curvulae Br.-Bl. 1926, alliance Caricion curvulae Br.-Bl. 1925 Boşcaiu 1971. In this paper we present some aspects of S. pumilio coenological integration in Iezer-Păpuşa Mountains. The Potentillo chrysocraspedae–Festucetum airoidis association was characterized based on some phytocoenological investigations made in this Massif. The identified relevés from Iezer-Păpuşa Massif were included in a phytocoenological table and the data were calculated by the Diemont method. Using this method we observed that bioforms are well represented by hemicryptophytes, followed by camephytes. With regard to phytogeographic elements, the Carpathian-Balkan, Eurasian and European-Arctic-Alpine are prevalent. The presence of Potentilla ternata species indicated the affiliation of this association to Carpathian-Balkan area

THE CHANGES OF SOME PHYSIOLOGICAL PARAMETERS IN PRUSSIAN CARP UNDER THE ACTION OF THE FOLPAN 80 WDG AND THE PROTECTIVE ROLE OF THIOUREA

This study was carried out to analyze the effects of sublethal and lethal concentrations of Folpan 80 WDG (30x10-5g Folpan 80 WDG /l water, 6x10-4g Folpan 80WDG /l water) and 1‰ thiourea on some physiological parameters (oxygen consumption, breathing frequency) on prussian carp (Carassius auratus gibelio Bloch 1782). The subacute and acute toxicity of Folpan 80 WDG fungicide and thiourea was evaluated in glass aquaria under semystatic conditions. Folpan 80 WDG produced, in all organized experimental variants a decrease in respiratory frequency and consumption of oxygen in the case of prussian carp, the more powerful the higher the concentration of the toxic was. Prussian carp anemia could be due to hypoxia that was induced by injuring the gills, as the red-pink colour of the gills became red-white, and at high concentrations the gills completely lost their red colour, while abundant secretions of mucus and even mucosal detachment with abundant bleeding could be observed. The antitoxic action of thiourea manifests itself by the fact that Folpan 80WDG are blocked by SH- groupings isothiourea, the mixture between Folpan 80WDG and thiourea produced no significant changes on the parameters physiological
