Our study is based on physicochemical, hydrobiologic and fisheries datas, for a comparative analysis to large scales over two years period (2009 and 2010), in order to characterize the complex ecosystems where Oued Cheliff ...
Lead is one of the most toxic heavy metals, it causes considerable damage in plants. This work is to
follow the behavior of the bean (Vicia faba L.) cope with stress of lead. This plant is used as a model in
ecotoxicological ...

Helicobacter pylori live in the human stomach. It is considered among the rare known micro-organisms being able to survive in such an acid environment. Currently the number growing of therapeutic failures is due to the ...
The Algerian steppe is the backbone of the pastoral activity. The sheep provides over 50% of red meat consumed locally; however, this grazed ecosystem it was for decades engaged in a process of degradation. The causes that ...
In arid and semi arid areas, soil salinization is a major ecological constraint. Unlike salt tolerant halophytes, most plants are stored in the group of glycophytes, whose physiological and biochemical processes are affected ...
Work presented is a contribution to the study of the complex Ascochyta sp agent
responsible for the anthracnose of pea.
Sixteen stocks of Ascochyta sp collected of two areas of the Algerian West
(Mostaganem and Mascara), ...
The plateau of Mostaganem represents a case of most affected ecosystem in Algeria
by degradation of its soil and water resources. It is a sandy coastal area covering over 78 100
hectares, characterized by a significant ...
The erosion of upstream watersheds in all its forms is considered a crucial problem in Algeria. It is the source of the siltation of hydraulic structures and loss of capacity. In the watershed of Wadi Mina, marly zone is ...
