Absolute Abundance

The Barn Owl, Tyto alba (Scopoli, 1769), is a nocturnal raptor species. Their diet includes small vertebrates, mainly rodents, and birds. To study their feeding in the desert area of Touggourt, we collected 153 pellets at the Ranou palm grove. We found 468 specimens belonging to 62 species. In terms of abundance, the item more consumed was Rodents (35.9%) followed by Insects (35.2%) and Birds (10.7%). In terms of absolute abundance, the prey more consumed was Brachytrypes megacephalus (21.4 %), followed by an undetermined Lacertidae species (9.2%) and Gerbillus nanus (8.8%). In terms of biomass, rodents contributed more to the diet of Tyto alba (44.66%) than birds (34.3%) and reptiles (12.06%). The highest value of biomass corresponded to Streptopelia sp. (15.7%), followed by Rattus rattus (14.1%) and an undetermined Lacertidae species (11.8%). To our knowledge, this is the first assess- ment of the diet composition of Tyto alba in the Saharan Touggourt area.

Guiera Senegalensis

Millions of people in the world depend on traditional medicinal plants for treatment of many diseases.  They have curative properties due to presence of various complex chemical substances of different composition, which are found as secondary plant metabolites in one or more parts of these plants. These plant metabolites according to their composition are grouped as flavonoids, tannins, alkaloids, saponins etc. Guiera senegalensis(Gs), which grows in abundance in semi-desert area of Western Africa such as Nigeria, has been used for treating specific diseases and wounds. The study is carried out to investigate the phytochemical analysis, toxicity, and the antifungal activity of Gs leaves extract. Keywords: Guiera senegalensis, Antifungal activity, Brine shrimp, toxicity, phytochemical analysis;
