Characteristics and sources of anthropogenic and biogenic hydrocarbons in sediments from the coast of Qatar.
( Elsevier , 2017 , Article)Surface sediment samples from the coastal zone of Qatar were collected and analyzed to determine the characteristics, and sources of anthropogenic and biogenic hydrocarbons. The main compounds in these surface sediments ... -
Diversity of benthic macrofauna and physical parameters of sediments in natural mangroves and in afforested mangroves three decades after compensatory planting
( Springer , 2018 , Article)Mangroves in the Arabian Gulf are under pressure from land use change, leading to compensatory planting at sites without natural mangroves. In this study, we examine the potential long-term success of this form of ... -
Uncovering the immunological repertoire of the carpet shell clam Ruditapes decussatus through a transcriptomic-based approach

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 ... -
Baseline concentrations and distributions of Polycyclic Aromatic Hydrocarbons in surface sediments from the Qatar marine environment
( Elsevier , 2017 , Article)Coastal sediments in marine waters of Qatar have the potential of being contaminated by Polycyclic Aromatic Hydrocarbons (PAHs) due to extensive petroleum exploration and transportation activities within Qatar's ... -
The importance of microbial mats for dolomite formation in the Dohat Faishakh sabkha, Qatar
( Springer Verlag , 2015 , Article)The Dohat Faishakh sabkha in Qatar is one of the rare modern environments where it is possible to study the formation of dolomite, a mineral whose origin has been long debated. In previous studies, dolomite formation in ... -
