Expression Patterns Of Genes Encoding Antioxidative Enzymes In Date Palm(phoenix Dactylifera) In Response To Salinity Stress
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Background Salinity is one of the major abiotic stresses threatening crop productivity worldwide. Plants exposed to severe salinity suffer ionic toxicities, osmotic stress and oxidative damage that lead to inhibition of ...

(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
Particulate matter (PM) pollution is one of the major environmental pollution issues severely affecting human health and air quality all over the world. Based on the recent World Health Organization (WHO) report, PM levels ...
Photochemical grafting of polysulfobetaine onto polyethylene and polystyrene surfaces and investigation of long-term stability of the polysulfobetaine layer in seawater
(
John Wiley and Sons Ltd
, 2018 , Article)
Low-density polyethylene (LDPE) and polystyrene (PS) films with hydrophilic surface were prepared by photochemical grafting of sulfobetaine-based copolymer containing photolabile moiety, and long-term stability of the ...
Foraging and habitat use of eastern cottontails (Sylvilagus floridanus) in an urban landscape
(
Springer Nature
, 2015 , Article)
Urban landscapes such as college campuses, arboretums, and backyards provide excellent habitats for education and research into animal behavior. We investigated aspects of the foraging activity of free-ranging Eastern ...
Foraging and habitat use of common duikers, Sylvicapra grimmia, in a heterogeneous environment within the Soutpansberg, South Africa
(
Wiley-Blackwell
, 2015 , Article)
We investigated aspects of the foraging behaviour and activity patterns of free-ranging common duikers (Sylvicapra grimmia) within the Soutpansberg, South Africa. We used giving-up densities (GUD) and camera traps to test ...

Bacillus thuringiensis subsp. aizawai strain HD133, known by its effectiveness against Spodoptera species, produces many insecticidal proteins including Cry1Ab, Cry1Ca and Cry1Da. In the present study, the insecticidal ...
Ecogenotoxicological Impact of Marine Pollutants on Qatari Bivalves: An Experimental Approach
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
The geographical and hydrological characteristics and industrial activities of the Arabian/Persian Gulf contribute to its classification as a stressed marine environment. The persistency of some contaminants released by ...
Current biodiversity and biogeography trends of reef-building corals in Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Coral reefs represent one of the most biologically and socio-economically important natural assets in the Arabian region, particularly in Qatar. Stress through increasing sea temperatures and salinities, growing development, ...
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 ...
