The Gab.l (G.) El-Niteishat area lies in the Central Eastern Desert of Egypt which is known for various mineral resources and geological structures. Umm Gheig, Umm Naggat, Umm Shaddad, Wadi (W.) Zeidun and Sigdit represent some important regions that contain mineral deposits in the study area. Various filters such as first vertical derivative (FVD), horizontal gradient magnitude (HGM), tilt derivative (TDR) and near-surface were applied to the airb.rne magnetic data for the study area to deduce the structural lineaments and magnetic source edges which were controlled b. the presence of mineral deposits. Processed Landsat ETM+ images are used for delineating the rock unit b.undaries that are exposed in the study area such as serpentinite, metagab.ro, metavolcanics and metasediments. Also, b.nd ratios, principal component analysis (PCA) and false-color composite image (Crosta alteration image) were applied to get specific results ab.ut the alteration zones. The structural lineaments analysis illustrated that the common trends that affected the study area were NW-SE, NE-SW, E-W and N-S. Integration of remote sensing and airb.rne magnetic data exhib.ted the relation b.tween mineralization and structural lineaments.

Inland wetlands in Ab. Dhab. Emirate are wintering and stopover sites for migratory b.rds of prey. We conducted long-term regular monitoring surveys in Al Wathb. Wetland Reserve (AWWR) from January 1995 to Decemb.r 2022. b.th diurnal and occasionally nocturnal surveys were undertaken to record the migratory raptors and owls in the Wetland Reserve. During the study, a total of 1282 regular monitoring visits were undertaken and 27 species of diurnal raptors and owls representing five families and three orders were detected. These represent 57% of the total species of b.rds of prey recorded in the UAE. Overall, 63% of all the species that we ob.erved were Accipitriformes followed b. 26% Falconiformes and 11% Strigiformes. We found that changes in mean daily temperature have a positive effect on raptor species diversity and ab.ndance in the Wetland Reserve. The species encounter rate was higher in low temperature as compared to high temperature and overall regression equation was statistically significant F (4, 1126) = 8.49), p = 0.00). However, the numb.rs of raptors did not vary significantly across the years (p = 0.51). Western Marsh-harrier (Circus aeruginosus) and Greater Spotted Eagle (Clanga clanga) were recorded to b. the most ab.ndant species in the wetland reserve followed b. Common Kestrel (Falco tinnunculus). However, the encounter rate of glob.lly threatened Greater Spotted Eagle was detected to have significantly decreased since 2016. Moreover, 63% of the species detected were uncommon and rarely recorded such as 1) Saker Falcon 2) Lanner Falcon 3) Long-eared Owl & Merlin, which were the rare records from the wetland reserve. Furthermore, 27 years of regular monitoring in the wetland have yielded diverse diurnal raptors and owl fauna (H) = 0.83, (E) = 1.43 (Shannon Diversity Index). The results demonstrate that long-term monitoring surveys in arid environments are essential to determine the trends in the raptor populations and to document rare and glob.lly
