Rhazya stricta, an evergreen poisonous shrub, is invading many rangeland areas in Saudi Arabia. A field study was conducted in Raudhat AI-Khafs to assess the relationship between R. stricta and Hammada elegans, a valuable and a dominant saltbush range plant in the area. Only eight perennial species were found in the site of which H. elegans and R. stricta were almost exclusively co-dominating t...

Hammada scoparia (Pomel) is a powerful plant with important biological properties. In this study, we report on the green synthesis of silver-doped nickel and copper nanoparticles (NPs) in presence H. leaf extract using self-propagating sol–gel autocombustion process. The synthesized NiO, CuO, Ag-NiO, Ag-CuO NPs were characterized Fourier transform infrared spectroscopy (FTIR) X-ray diffraction ...

This study aimed to analyze the chemical profile and evaluate biological activities of aqueous extract H. Scoparia, an endemic plant found in Southeastern Algeria. The was subjected phytochemical screening, RP-HPLC, FT-IR analysis. anti-inflammatory activity examined using protein denaturation method, photoprotective evaluated UV-Visible spectrophotometry. antioxidant assessed ABTS, DPPH, FRAP ...

BACKGROUND Pastoral populations around the world hold complex and detailed ethnoveterinary knowledge, essential for the survival of their herds and securing their livelihood. In recent decades, several studies have given attention to local veterinary remedies and practices and their validation, and to the local conceptualization of livestock diseases. Despite this, relatively little has been re...

The HGL-50 locality, situated on the Glib Zegdou outlier in the Gour Lazib of Algeria (Hammada du Dra), is famous for having yielded several dental remains of primates dating from the late Early to the early Middle Eocene. These primates include Algeripithecus minutus, Azibius trerki and a new species of cf. Azibius (not described yet). Algeripithecus was widely acknowledged to be one of the ol...
