Bacterial community structure and predicted function in the rhizosphere of wild and cultivated date palms: Effects of Fertilizers on Composition and Functionality
( Elsevier , 2023 , Article)This study investigated bacterial diversity in date palm rhizosphere and assessed the influence of different fertilizers on diversity using metagenomics. A total of 6356 Operational Taxonomic Units (OTUs) and 1164425 ... -
Baseline concentrations of mercury species within sediments from Qatar's coastal marine zone
( Elsevier , 2019 , Article)Baseline concentration of total mercury (THg), organic extractable mercury and methylmercury (CH3Hg) concentrations in sediments from the northeastern, eastern and southeastern parts of the Arabian Gulf were assessed. ... -
Baseline distribution of petroleum hydrocarbon contamination in the marine environment around the coastline of Qatar
( Elsevier Ltd , 2023 , Article)Levels of organic contaminants (TPHs, PAHs) were simultaneously determined in both abiotic (sediments, seawater) and biotic (Pinctada radiata oysters) samples at four sites along the coastline of Qatar (Arabian Gulf) in ... -
Chemical Composition, Antioxidant Capacity, and Anticancerous Effects against Human Lung Cancer Cells of a Terpenoid-Rich Fraction of Inula viscosa
( MDPI , 2024 , Article)Inula viscosa is a widely used plant in traditional Mediterranean and Middle Eastern medicine for various illnesses. I. viscosa has been shown to have anticancer effects against various cancers, but its effects against ... -
The effect of type and combination of fertilizers on eukaryotic microbiome of date palm rhizosphere
( Springer Nature , 2024 , Article)The date palm (Phoenix dactylifera) is an important cultivated crop in arid areas. Here, we studied the effect of plant genotype and type of fertilizers on the eukaryotic community structures of the date palm rhizosphere. ... -
Environmental contamination in mangrove crustaceans inhabiting Qatari waters
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference)The increasing level of pollutants in the marine environment is a major concern in all countries, in particular where the main diet is seafood. The major goal of this project was to assess the level of pollution and their ... -
First genotoxicity assessment of marine environment in Qatar using the local Pearl oyster Pinctada radiata
( Elsevier , 2017 , Article)The Arabian Gulf countries’ marine environment has been subjected to increasing industrial development and anthropogenic pressure, leading to the growing introduction of contaminants into the marine environment, with a ... -
First Impact Assessment of Genotoxic Components in the Qatari Marine Environment
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference)The Arabian Gulf is a semi-enclosed sea with very high evaporation and low discharge rates resulting in extreme saline and thermal conditions. Additionally the system is characterized by a weak hydrodynamic flushing resulting ... -
