Soil salinization is a major limiting factor in agricultural productivity, especially in
arid and semi-arid region. The presence of soluble salts at high concentrations in the soil,
affect physiological mechanisms of the ...
A study of the reproduction of the black sea urchin Arbacia lixula from Mostaganem coastline was conducted at two different sites, one (Salamander) rocky, rich in photophilous algae but disturbed by pollution (urban and ...
This study, allowed us to put the light on marine invertebrate groups (echinoids, Holothuroidea, ophiuroids, Asteroidea and crinoids), rarely studied, in the Mediterranean sea. These echinoderms are studied in a shallow ...
The objective of our work is to study separately the influence of copper and zinc as
sulfates CuSO4 and ZnSO4 at doses of 0, 50 ,100 ,200 ,300 ,400 ,500 ,1000 et 2000ppm, on
the chemical, morphological and biometrical ...
These studies aim to evaluate the quality of coastal Western Mediterranean sea of Algeria. The studies consist on monitoring seasonal changes in biological (biometric and physiological) indices and observing of accumulation ...
In this study, we have revised the systematics of some aspidochirote holothurians of the Algerian
coast, using a part of a database provided by Mezali (2008). The detailed study of the
morphological, anatomical, molecular ...
Our work focuses on the study of saponins isolated from the starfish Echinaster sepositus. Saponins are extracted from bodywall (aboral face and oral face), gonads, stomach and pyloric caeca by different techniques of ...
Salinity is a major abiotic stress affecting crops and plants production. Oxidative stress associated with it is often caused by excessive generation of reactive oxygen species. One of the mechanisms of non-enzymatic defense ...
Salinity and accumulation of pesticides residues in soils represent serious constraints for
plants. This can induce high levels of stress, reducing biomass and altering physiological and
biochemical processes in plants. ...
In arid and semi-arid regions, soil salinity is a major environmental stress.
Conversely halophytic tolerant salts, most plant species are classified in the group of
glycophytes, whose physiological and biochemical ...
Natural plant extracts contain a variety of phenolic compounds to which are assigned a variety of biological activities. In this context, we attempted to evaluate the antioxidant activity of different extracts prepared ...
Urolithiasis is a common and multifactorial complex that requires an understanding of the mechanisms involved in the pathology lithogenesis. Supersaturation of urinary medium is the initial stage of lithogenic process that ...
Recently, special attention was given to Aspidochirotid holothurians colonizing Posidonia oceanica meadows of the Algerian coasts. Indeed, these macrofaunal detritic-feeders, commonly called "sea cucumber", belong to an ...
Urolithiasis is a common and multifactorial complex that requires an understanding of the mechanisms involved in the pathology lithogenesis. Supersaturation of urinary medium is the initial stage of lithogenic process that ...
The principal goal of this study is to contribute to the quantitative and qualitative evaluation, in order to explore the diversity of the phytoplankton community of three station of the Algerian coastal shallow waters ...
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 ...
The coastal marine ecosystems of Mostaganem, like all the coastline of the Mediterranean Sea, are a fragile space, vulnerable, limited and coveted. It is the environments were increasingly affected by human activities and ...
The work we did on urolithiasis in western Algeria consisted of:
1) In an study of the physicochemical parameters such as age, sex, temperature, pH, and
density and its influence on the formation of urinary crystals.
2) ...
The objective of our work is to study the combined effect of lead and bentonite on the
physiological and biochemical characteristics of two species of Atriplex: Atriplex halimus. L
and Atriplex canéscens L.
Sowing was ...
