Biologie Résumé :
This work represents a first study of the biodiversity of the actinomycetes inhabitants three Sebkhas protected by the Ramsar-Algeria convention. The physicochemical analyzes of the soil samples revealed extremely high salinities, basic or very basic pH, low percentages of moisture, moderate or very high percentages of organic matter. These results also showed that samples of sebkha Annk Djemel belong to the ""clay"" and ""Clay loam"" classes, samples of sebkha Guellif belong to the ""clay loam"" and ""sandy-clay loam"" classes and samples of sebkha Et Taref belong to the ""clay"" class. An isolation of actinomycetes from the soil has been achieved by the use of conventional methods and / or Culturomics. The enumeration results revealed that the number of actinomycetes could reach to
2.105 CFU/g of soil. Based on the enumeration results, a statistical analysis, carried out by the application of non-parametric tests of Kruskal-Wallis and Mann-Whitney, revealed that culture media relatively poor in nutrients and the concentration 5% of NaCl are the most favorable in the isolation of actinomycetes. The competitive effect of bacterial and fungal flora has also been highlighted. Following the isolation protocols adopted, we were able to purify and store a total of 204 isolates, all Gram (+), of which 108 isolates were derived from conventional isolation techniques and 96 isolates were obtained by the Culturomics method. Identification by the MALDITOF MS and sequencing of the 16S rDNA methods allowed us to identify a new species that we named Streptomyces massilialgeriensis sp. nov. and to assign certain other isolates to the genera Streptomyces, Nocardiopsis and Actinomyces. Other isolates have been identified as Bacillus, Virgibacillus, Gracilibacillus, Staphylococcus, Flavonifactor and Halobacillus. The activity test, carried out by the agar plug diffusion method, of 13 selected isolates belonging to the genera Streptomyces and Nocardiopsis against multidrug-resistant bacteria reveal interesting zones of inhibition of the isolate S20 against K. pneumoniae CSUR P1596 (coli R), E. coli CSUR P4969 (coli R, HLP), E. coli CSUR P5139 (carba R) and P. mirabilis CSUR P2049 (oxa-48), and isolate S112
against S. aureus CSUR P1943 (MRSA, KTG, inducible MLSB), E. coli CSUR P4969 (coli R, HLP) and P. mirabilis CSUR P2049 (oxa-48).

Biologie Résumé :
A combination of cultural and culture-independent (the latter is metagenomics by molecular cloning) techniques, was used to study the biodiversity of halophilic and halotolerant Actinobacteria, living in Ezzemoul sebkha, Chott Tinsilt and Djendli sebkha soils (located in northeastern Algeria). These ecosystems are mainly, extremely saline, alkaline, with low moisture content. According to the phylogenetic analysis of the 16S rDNA gene sequences: 40 isolates from the Ezzemoul site are assigned to species of the genera Nocardiopsis (dominant), Streptomyces and Rhodococcus; Another 42 isolates from the Tinsilt site are attributed to Streptomyces (dominant), Nocardiopsis, Actinopolyspora and Brevibacterium; and 22 isolates from the Djendli site belong to the same genera Streptomyces (dominant) and Nocardiopsis. Among all these isolates, there is a high probability of the presence of many new species. In addition, 24 clone sequences derived from the Ezzemoul site are affiliated with the genera Demequina (dominant), Plantactinospora, Friedmanniella and Mycobacterium. Also, 15 clone’s sequences from the Djendli site are related to the genera Marmoricola, Phytoactinopolyspora and Streptomyces; and to an unclassified actinobacterial clone. Some sequences (from both sites) are related to uncultured clones and/or not belonging to the class Actionbacteria (dominant in the site Djendli). Furthermore, the isolates obtained from the three study sites are: moderately halophilic and halotolerants, mesophilic, neutrophilic or acid-alkali-tolerant. Several of them can produce at the same time, extracellular hydrolytic enzymes such as cellulase, amylase, lipase, pectinase and proteases; as well as bioactive molecules against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) and fungi (Candida albicans and Aspergillus niger). The results of this research show a wide taxonomic, physiological and metabolic diversity of Actinobacteria, from sebkhas and chott. These bacteria can therefore be excellent candidates for future biotechnological applications.

Biologie Résumé :
The objective of our work is to describe the biodiversity of earthworm fauna in Eastern Algeria, along a gradient from the coast to the desert and their relations with soil (pH, electrical conductivity, organic matter and soil texture) and climatic factors. Eighteen species are identified in this study: Aporrectodea trapezoides, Aporrectodea rosea, Allolobophora molleri, Aporrectodea montícola, Octodrilus complanatus, Aporrectodea carochensis, Octodrilus maghrebinus, Eisenia fetida, Dendrobaena byblica, Aporrectodea tetramammalis, Eiseniella tetraedra, Proctodrilus antipae, Octolasion lacteum, Aporrectodea caliginosa, Allolobophora chlorotica, Microscolex dubius, Microscolex phosphoreus and Hormogaster redii.
The species Ap. trapezoids dominates throughout the field of study (PDC = 50,37%).
Regarding the demoecology, the average values of density and earthworm biomass, reduce from the north (40,50 ± 11,86 individuals / m2 and 6,92 ± 4,88 g / m2) to the south (3,89 ± 2,80 individuals / m2 and 1,07 ± 0,83 g / m2) of the study transect.
Species Aporrectodea rosea and Aporrectodea trapezoides Allolobophora molleri can withstand environments rich in sand. Their substrates are rich in nitrogen. However, Octolasion lacteum, Octodrilus maghrebinus, Dendrobaena byblica, Aporrectodea carochensis and Microscolex dubius show trends towards high levels of organic matter and clay. The group of Aporrectodea caliginosa, Aporrectodea monticola Octodrilus complanatus, Allolobophora chlorotica and Hormogaster redii is related to parameters CaCO3, Ca ++, the silt fraction and poor sites in organic matter.
It seems that both species Aporrectodea rosea and Aporrectodea trapezoides can withstand hot, dry climate like that of Algeria.

Knowing its importance in forensic science, this study contributestothe improvement of the knowledge on the biodiversity of the scavenging fauna and a better understanding of the activity of Diptera, Calliphoridae during the four seasons of the year for this family is
considered the most important in dating the Interval Post Mortem (IPM).
For these experiments, four dog corpses (Canis) have been used as substrates,each in a different season of the year 2012/2013.The study was conducted in an open space near the laboratory of Biosystematics and Ecology of Arthropods in ChaabatErsas (36 ° 20'16.20 ""N; 6 ° 37'33.32"" E) Constantine, Algeria.
One hour after the dogs’ euthanasia, they have been put in a cage covered with an iron fence to protect them from predators.From this moment, daily samples of the adult necrophagous insects present on the corpses and thereabouts have been taken.
Daily sampling allowed us to harvest a total of 2132 necrophagous insects belonging mainly to three types namely that of Diptera (43.99%), Coleoptera (55.44%) and Hymenoptera (0.56%). ). 23 necrophagous species have been listed.
The analysis of the results reveals that the fauna collected on the corpse in Spring is the most diversified compared to the other three seasons, and that the Diptera Calliphoridae belonging to the genera Lucilia and Chrysomia (green flies) are more adapted to the heat, unlike those belonging to the genus Calliphora (blue flies) which are better adapted to the cold.
Moreover, the obtained results reveal that the colonization of the substrate by necrophagous insects varies depending on the seasons and therefore the climatic conditions.
