Decline in oyster populations in traditional fishing grounds; is habitat damage by static fishing gear a contributory factor in ecosystem degradation?
( Elsevier , 2018 , Article)The territorial waters of Qatar once supported dense assemblages of the pearl oyster Pinctada radiata. The oysters settled on a patchy network of limestone platforms (hairãt) and provided a suite of ecosystem services to ... -
Environmental contamination in mangrove crustaceans inhabiting Qatari waters
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference Paper)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 Impact Assessment of Genotoxic Components in the Qatari Marine Environment
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)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 ... -
Investigating the biodiversity and current status of the historically renowned oyster beds of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference Paper)The "Pearl Oyster" Pinctada radiata has long been associated with the nation of Qatar.

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 ... -
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 ... -
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 ... -
Mercury accumulation in Lethrinus nebulosus from the marine waters of the Qatar EEZ
( Elsevier , 2017 , Article)Total mercury (THg) and methylmercury (MeHg) were recorded in the commercial demersal fish Lethrinus nebulosus, caught from six locations in Qatar EEZ (Exclusive Economic Zone). Concentrations of THg decreased in the ... -
