This survey was conducted in Al-Kalakla Fishery (KF) and Jabel Awlia Dam Fishery (JADF) in the White Nile River, Khartoum state to identify the selective and non-selective fishing gear. The results showed the selective fishing gear represented by gill-nets and seine nets (beach nets) in both fisheries with clear variation in use. In KF, fixed nets were dominant (56%) in fishing and followed by ...

BACKGROUND West Nile fever virus is a zoonotic arboviral infection maintained in a sylvatic cycle involving mosquito vectors and birds. It is one the arboviruses whose geographical range is expanding because of climate and land use changes that enhance the densities of mosquitoes and promote mosquito-bird-human interactions. We carried out a survey to determine the reservoirs of WNV among wild ...

Ethiopian agriculture and Nile River flows are heavily dependent upon the Kiremt season (June– September) precipitation in the upper Blue Nile basin, as a means of rain-fed irrigation and streamflow contribution, respectively. Climate diagnostics suggest that the El Niño–Southern Oscillation phenomenon is a main driver of interannual variability of seasonal precipitation in the basin. One-seaso...

Aim: The survey was carried out to detect antiC. burnetii antibodies in goat's sera samples in eight States in the Sudan during September 2010 – July 2011. Materials and Methods: In a preliminary study, four hundred and sixty caprine sera samples collected from eight States in the Sudan were screened for antiCoxiella burnetii (the causative agent of Q fever) antibodies using a commercial indire...

Climate change is likely to have severe effects on water availability in Ethiopia. The aim of the present study was to assess the impact of climate change on the Gilgel Abay River, Upper Blue Nile Basin. The Statistical Downscaling Tool (SDSM) was used to downscale the HadCM3 (Hadley centre Climate Model 3) Global Circulation Model (GCM) scenario data into finer scale resolution. The Soil and W...

We found that the dye nile red, 9-diethylamino-5H-benzo[alpha]phenoxazine-5-one, can be applied as a fluorescent vital stain for the detection of intracellular lipid droplets by fluorescence microscopy and flow cytofluorometry (J. Cell. Biol. 1985. 100: 965-973). To understand the selectivity of the staining, we examined the fluorescence properties of nile red in the presence of organic solvent...

Land use/land cover change and climate have diverse impacts on the water resources of river basins. This study investigated trends land in Nile River Basin. The were analyzed using Mann–Kendall test, Sen’s slope estimator test an innovative trend analysis method. (LULC) was examined Landsat Thematic Mapper (TM) Enhanced (ETM+) with a resolution 30 m during 2012–2022. findings revealed that fore...

This work aims to utilize oxygen and hydrogen stable isotopes as tracers for determining the groundwater sources of recharge in central Nile delta. The analyzed water samples were collected from canals drains surface water, soil shallow, intermediate deep zones groundwater. isotopic data indicated that have higher content than recent river (? 18O = 2.39‰ ?2H 22‰) which reflect influence an evap...
