    EFECTUL PĂSTRĂRII ÎNDELUNGATE A RELEVEELOR DE SOL ÎN CONDIŢII DE LABORATOR ASUPRA COMPONENŢEI ALGOFLOREI EDAFICE DIN PĂDURILE DE FAG
    (CEP USM, 2009) Şalaru, Victor; Şalaru, Vasile; Melnic, Victor
    The analysis of brown soil on which has been kept in the laboratory conditions for 15-18 years and helped us to distinguish 22 species of algae in comparison with these 48, which was established in the first period of investigation (1984-1987 years). The algae community which was established in the years 2000-2002, are characterized by the predominance of representatives green algae fillum. A long preservation of soil samples in the laboratory for 15-18 years, is contributing to the disapperence of algae from Bacillariophyta fi llum, decreasing green and from Xanthophyta fillum algae diversity, which decreases the number more than twice with a lesser extent it influences on the Cyanophyta fillum. The most resistant were found to be Cyanophyta fillum fi laments form, which are characterized by the presence of a mucilaginous sheath which is well pronounced.

    STUDIU COMPARAT CU PRIVIRE LA DISTRIBUIREA COMUNITĂŢILOR ALGALE DIN DIFERITE AGROFITOCENOZE ALE ZONEI DE CENTRU A REPUBLICII MOLDOVA
    (CEP USM, 2008) Chicu, Neli
    En comparant la structure taxonomique des communités d’algues édaphiques et des écobiomorphes algales des solsoccupés par les différentes cultures agricoles on a constaté que les surfaces où l’on cultive le blé se caractérisent par laplus haute diversité des espèces d’algues et c’est possible grâce à la plus grande diversité en comparaison avec d’autrescultures agricoles des représentants des xanthophytes, chlorophytes et surtout des cyanophytes. En même temps lamoindre diversité des espèces algales a été constatée pour les terrains occupés par des vignes.
