“…The MB is a bright, sunny place with rocky and stony slopes, creating a favourable environment for Uromastyx acanthinura and Daboia mauritanica. The "La Fouette queue" is well known in the Sahara, this lizard occurs in all rocky and stony areas (Le Berre 1989), similar to another species of the same genus: Uromastyx ocellata, reported in Egypt in the mountains and at the foot of hills, where it inhabits gorges and rocks and which could be attributed to the terrestrial petrodophilic ecological type (Milto et al 2019).…”

This study is the first contribution to the evaluation of reptile diversity in different habitats of M’sila region, Algeria. We carried out 94 trips between 2016 and 2018 across three sites: Mergueb (six stations), L’mhazem (three stations) and Kaf Afoul (two stations), on average, accompanied by prospectors. Our aims were to make an inventory of reptilian species in this region, as well as to study their diversity, distribution, ecology and abundance. Altogether, we recorded 193 specimens belonging to 22 species: two turtles, one amphisbaenian, twelve lizards and seven snakes. Two species classified as Near Threatened by the IUCN were recorded: Uromastyx acanthinurus (Bell, 1825) and Daboia mauritanica (Duméril & Bibron, 1848). Statistical analysis revealed that the type of habitat directly influences the distribution of reptiles in the study area. Although this small area is rich in reptilian species, their abundance remains low and worrying

“…It has a diverse ecological distribution in almost all African countries according to the temperature, rainfall, soil type, and location 1 . In Egypt, it is naturally distributed in all desert regions except the Mediterranean and north Red Sea strips [2][3][4] . B. aegyptiaca organs have been used worldwide in folk medicine.…”

Balanites aegyptiaca (L.) Delile is a medicinal wild tree, naturally distributed in wide regions of Africa and South Asia. The fruits are commercially available in Egypt as antidiabetic natural products. The current study aimed to determine the effects of environmental factors on the metabolites and the bioactivities of fruit and leaf extracts. The main ecological differences between the sites of collection, Wadi El−Gemal and Baris Oasis, are temperature, aridity, humidity, and location. The fruit extract of Baris Oasis showed higher saponin content and saponin metabolites (LC−MS analysis) than the fruit extract of Wadi El−Gemal. Baris Oasis fruit extract showed twice the inhibition of α−Glucosidase than Wadi El−Gemal fruit extract. Twelve phenolics and flavonoids were detected in Baris Oasis leaf extract, while ten compounds were detected in Wadi El−Gemal leaf extract using HPLC. The higher quality and quantity of flavonoids and phenolics of Baris Oasis leaf extract than Wadi El−Gemal leaf extract, have significant effects on the antioxidant and acetylcholinesterase inhibitory activities. In conclusion, elevation of temperature and aridity have significant positive effects on the synthesis and accumulation of B. aegyptiaca saponins, phenolics and flavonoids. The bioactivities of the fruit and leaf extracts are directly proportional to the variation in metabolites due to abiotic stresses.
