    ВИДОВОЙ СОСТАВ ВОДОРОСЛЕЙ ПОЧВ КСЕРОФИТНО-ЛЕСНОГО ЧЕРНОЗЁМА
    (CEP USM, 2010) Шалару, Виктор; Шалару, Василе; Визитеу, Наталья; Мельник, Виктор
    În articol sunt prezentate date privind componenţa algelor edafice în cernoziomurile xeroforestiere. Algoflora edafică depistată în aceste soluri include 98 de specii şi varietăţi din 11 ordine, 24 familii şi 47 genuri. Majoritatea algelor din comunitatea evidenţiată aparţin filumului Chlorophyta şi ceva mai puţin filumului Cyanophyta, ceea ce în linii generale corespunde cu legitatea distribuţiei algelor în solurile de pădure.

    ALGOCENOZELE EDAFICE DIN PREAJMA GUNOIŞTII SATULUI OLĂNEŞTI, R-NUL ŞTEFAN VODĂ
    (CEP USM, 2010) Melniciuc, Cristina; Strețco, Ana
    This study reflects a negative influence on the biota of dumps neighboors, particularly algae communities. The dominant species are from Bacilariophyta and Cyanophyta filuma, being the most resistant to extreme conditions.

    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.

    GRUPELE ECOLOGICE DE ALGE EDAFICE DIN SOLURILE UNOR TIPURI DE AGROFITOCENOZE
    (CEP USM, 2008) Şalaru, Victor; Şalaru, Vasile; Chicu, Neli
    Dans le présent article on analyse les résultats des recherches consacrées à l’évidence des groupes écologiquesdes algues édaphiques les plus fréquentes chez les cultures agricoles par rapport aux écobiomorphes algales descommunités d’algues édaphiques des sols plantés de différentes cultures agricoles. On a constaté que des écobiomorphes comme les formes algales du type: X, Ch, C, CF, P, H et B étaient communes pour les types d’agrophitocénoses étudiés;à la fois pour chacune d’entre elles des traits spécifiques ont été dépistés.

    CONTRIBUŢII LA STABILIREA STRUCTURII TAXONOMICE A ALGELOR EDAFICE ÎN UNELE AGROFITOCENOZE DIN ZONA CENTRALĂ A REPUBLICII MOLDOVA
    (CEP USM, 2008) Chicu, Nelea
    Dans cet article on analyse la structure taxonomique des communautés d’algues édaphiques des agrofitocénoses occupées par diverses cultures agricoles. Les recherches effectuées ont montré que l’algoflore édaphique dans les terres utilisées de la zone centrale de Moldova est très riche, surtout sous l’aspect de la structure taxonomique et des particularités taxonomiques biologiques des espèces représentatives. La présence dans la structure des communautés algales d’un nombre suffisant des espèces de cyanophytes azotofixateuses est une preuve de la fertilité naturelle du sol.
