Phytoremediation of polluted soils and waters by native Qatari plants: Future perspectives
( Elsevier , 2020 , Article Review)Because pollution is predicted to worsen and sources of quality water for agriculture and other human activities are limited, many countries have been motivated to seek novel water sources. Qatar relies on groundwater and ... -
Investigation of heat-resistant antifungal agents from Bacillus amyloliquefaciens and Bacillus subtilis for biocontrol of mycotoxigenic fungi
( Elsevier , 2024 , Article)Fungal infections of food and feed with toxigenic strains results in the accumulation of harmful metabolites. In this study, the antifungal activity of two indigenous bacterial strains Bacillus amyloliquefaciens and Bacillus ... -
Isolation, biochemical and molecular characterization of 2-chlorophenol-degrading Bacillus isolates
( Academic Journals , 2007 , Article)Pure cultures of 2-chlorophenol degrading bacteria were isolated from a natural enrichment that may be adapted to chlorophenols in the industrial zone at Umm-Saied city (Qatar). The bacteria were identified by 16S rDNA ... -
Halophytes and associated properties of natural soils in the Doha area, Qatar
( Michigan State University Press , 2007 , Conference)Plant life and the life they support are being eliminated and cannot cope with the construction activities in Doha City. One of the most important reasons behind this study is the fast rate at which many habitats are ... -
Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and reproduction
( Elsevier B.V. , 2022 , Article)Estrogens, such as the 17β-estradiol (E2) and the 17α-ethinylestradiol (EE2), have been regarded as a global threat to aquatic ecosystems due to their pseudo-persistence, their high estrogenic activity and their toxicity ... -
Global variability in seawater Mg:Ca and Sr:Ca ratios in the modern ocean
( National Academy of Sciences , 2020 , Article)Seawater Mg:Ca and Sr:Ca ratios are biogeochemical parameters reflecting the Earth–ocean–atmosphere dynamic exchange of elements. The ratios’ dependence on the environment and organisms’ biology facilitates their application ... -
A novel index based on planktonic copepod reproductive traits as a tool for marine ecotoxicology studies
( Elsevier B.V. , 2020 , Article)Copepods are excellent bioindicators of climate change and ecosystem pollution in anthropized coastal waters. This work reviewed the results of previous studies examining changes in egg production rate (EPR), hatching ... -
Population dynamics and predatory impact of the alien jellyfish Aurelia solida (Cnidaria, Scyphozoa) in the Bizerte Lagoon (southwestern Mediterranean Sea)
( Hellenic Centre for Marine Research , 2020 , Article)Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate the impact that these organisms may have on local populations, biodiversity, and ultimately on the functioning ... -
Phytoplankton size changes and diversity loss in the southwestern Mediterranean Sea in relation to long-term hydrographic variability
( Academic Press , 2020 , Article)Structural changes in plankton primary producers have large implications for food web dynamics, energy fluxes and the vertical export of biogenic particulate carbon. Here we examine phytoplankton data spanning the period ... -
Zooplankton abundance and community structure driven by tidal currents in a Mediterranean coastal lagoon (Boughrara, Tunisia, SW Mediterranean Sea)
( Academic Press , 2021 , Article)Lagoons and coastal marine zones are very productive and useful ecosystems, but they are threatened by the effects of global change and anthropogenic pressures. These effects have a negative impact on the zooplankton, ... -
Unfolding jellyfish bloom dynamics along the mediterranean basin by transnational citizen science initiatives
( MDPI AG , 2021 , Article)Science is addressing global societal challenges, and due to limitations in research financing, scientists are turning to the public at large to jointly tackle specific environmental issues. Citizens are therefore increasingly ... -
The perils of building big: Desalination sustainability and brine regulation in the Arab Gulf countries
( Elsevier , 2024 , Article)Seawater desalination has become an accessible option for augmenting freshwater supplies worldwide. In the countries of the Gulf Cooperation Council (GCC), it has been practiced for decades as the main source for domestic ... -
Widespread diversity deficits of coral reef sharks and rays
( American Association for the Advancement of Science , 2023 , Article)A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed ... -
