Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
( Springer International Publishing , 2016 , Article)The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ... -
Making sense of multivariate community responses in global change experiments
(2022 , Article)Ecological communities are being impacted by global change worldwide. Experiments are a powerful tool to understand how global change will impact communities by comparing control and treatment replicates. Communities consist ... -
A MALDI-TOF study of bio-remediation in highly weathered oil contaminated soils
( Elsevier , 2018 , Article)We have shown that Bacillus cereus is dominating the bacterial population at three polluted oil-industry sites where weather and soil conditions are extreme in terms of temperature, UV-radiation and salinity. A minor ... -
Mangrove carbon stocks and biomass partitioning in an extreme environment
( Elsevier , 2020 , Article)Global inventories that show mangrove forests have rich carbon stores currently lack data from arid areas where carbon stocks may be functionally impoverished relative to humid regions. We quantified total carbon stocks ... -
Mangrove-bearing limestone from the Eocene Dammam Formation, Arabian Gulf: Implications for the mangrove dispersal controversy
( springer link , 2012 , Article)Fossil mangrove remains are found within the shallow carbonate strata of the Middle Eocene Dammam Formation of the Arabian Gulf. This formation is of wide distribution across most eastern parts of the Arabian Platform and ... -
Mapping and accuracy assessment of siltation of recharge dams using remote sensing technique

Mapping biodiversity conservation priorities for protected areas: A case study in Xishuangbanna Tropical Area, China
( Elsevier , 2020 , Article)Global biodiversity is declining rapidly, posing a severe threat to ecosystem functions and services. Protected Areas (PAs) can be extremely effective in protecting biodiversity, but conservation gaps arise as a result of ... -
Mapping of aeolian deposits of an industrial site in the arid region using the TIR bands of ASTER and study of physicochemical characters and stabilization of sand erosion
( Taylor and Francis Group , 2022 , Article)This study describes the spectral emissive character of silicate and carbonate minerals of aeolian deposits and maps the deposits and sand encroachments that occurred in and around the site 5/6 of Qatar Fertilizer Company ... -
Mapping of trace elements in topsoil of arid areas and assessment of ecological and human health risks in Qatar
( Elsevier , 2023 , Article)Soil is the incubator of human activities. Mapping of soil contaminants needs to be constantly updated. It is fragile in arid regions, especially if it accompanies dramatic and successive industrial and urban activities ... -
Marine collection in Qatar - basis for biodiversity management
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference Paper)Biological Collections, which deal directly with identifying and documenting biodiversity, have a major role in assisting biodiversity management. They form the basis for research, documenting flora and fauna and creating ... -
The maxima in northerly wind speeds and wave heights over the Arabian Sea, the Arabian/Persian Gulf and the Red Sea derived from 40 years of ERA5 data
( Springer , 2020 , Article)Recent studies point out the importance of northerly winds and waves in the Arabian Sea, especially those due to shamal and makran events in addition to the northeast monsoon system. We have analyzed climatology and trends ... -
Measurement and modelling of nitrogen dioxide (NO2) emissions: a marker for traffic-related air pollution in Doha, Qatar
