Accumulation of Trace Metals, Petroleum Hydrocarbons, and Polycyclic Aromatic Hydrocarbons in Marine Copepods from the Arabian Gulf
( Springer Verlag New York Inc , 2001 , Article)In this study, zooplankton samples were collected from the coastal waters of Qatar during winter and summer 1998 to assess the impact of growing industrialization on the bioaccumulation of trace metals, total petroleum ... -
An Equatorial Pacific rain event: influence on the distribution of iron and hydrogen peroxide in surface waters
( Elsevier , 2001 , Article)The wet deposition of iron and peroxides was monitored during an intense rain squall in the equatorial Pacific Ocean. Iron and hydrogen peroxide were determined at sea using adsorptive cathodic stripping voltammetry (ACSV) ... -
Phytoplankton-zooplankton relations in three inland seas along the Qatari coast (Arabian Gulf)
( Taylor and Francis Ltd. , 2005 , Article)Phyloplankton and zooplankton community structures and abundance were studied in three inland seas around Qatar, two along the eastern coast and one along the northwestern coast. Despite some irregularities, the direct ... -
Feeding on intertidal microbial mats by postlarval tiger shrimp, Penaeus semisulcatus De Haan
( Springer Berlin / Heidelberg , 2009 , Article)A series of experiments investigated the potential role of microbial mats in nutrition of the early settlement stages of Penaeus semisulcatus. From 3 days post-metamorphosis, the microbial mat supported high growth and ... -
Sources of primary production supporting food webs in an arid coastal embayment
( Springer Nature , 2012 , Article)Penaeid shrimp can be useful ecological indicators of linkages between shallow tropical coastal habitats, acting as integrators of carbon and nitrogen sources due to their generalist feeding habits and their mobility between ... -
Phytoplankton along the coastal shelf of an oligotrophic hypersaline environment in a semi-enclosed marginal sea: Qatar (Arabian Gulf)
( Elsevier , 2013 , Article)Phytoplankton biomass (chlorophyll a concentration), primary production, abundance, species diversity and species groupings were measured in the coastal waters surrounding Qatar (Arabian Gulf) at 13 stations in February ... -
Are mangroves in arid environments isolated systems? Life-history and evidence of dietary contribution from inwelling in a mangrove-resident shrimp species
( Elsevier , 2013 , Article)The Arabian Gulf represents one of the more northerly extremes of mangrove distribution in the Indo-Pacific, and is populated only by Avicennia marina, due to its tolerance of high salinity and wide temperature extremes. ... -
Dangerous anthropogenic climate change. Are we closer than we think? A 2016 update
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)In this presentation, I will outline the fundamentals of climate change science with respect to 'real-world' climate observations, and evidence from the Earth's paleoclimate (climate history) record. In particular, I will ... -
Evaluation Of The Sensitivity Of Qatari Marine Microalgae Synechococcus Sp, To Three Reference Toxicants
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Background Marine phytoplankton form the basis of the marine food chain and are essential for the normal functioning of ecosystems. Any disturbance to this component, due to the release and accumulation of toxic compounds ... -
The effect of density in larval rearing of the pullet carpet shell Venerupis corrugata (Gmelin, 1791) in a recirculating aquaculture system
( John Wiley & Sons Ltd , 2014 , Article)The pullet carpet shell Venerupis corrugata is an economically valuable species in several European countries, however, nowadays stocks are under high fishing pressure. Hatchery production of juveniles for release is a ... -
Insights on the association between somatic aneuploidy and ostreid herpesvirus 1 detection in the oysters Crassostrea gigas, C. angulata and their F1 hybrids
( John Wiley & Sons Ltd , 2014 , Article)Cytogenetic abnormalities associated with viral infections, including from viruses of the Herpesvirales order, have been reported in vertebrate species. Ostreid herpesvirus 1 (OsHV-1) has been detected worldwide during ... -
Outwelling from arid mangrove systems is sustained by inwelling of seagrass productivity
( Inter-Research , 2014 , Article)Mangrove forest productivity is normally sustained by nutrients from terrestrial runoff, with freshwater inputs driving the resulting outwelling of production, but arid mangroves lack this input. The movement of material ... -
Short-term behavioural responses to thermal stress by hawksbill turtles in the Arabian region
( Elsevier , 2014 , Article)We present a previously unrecorded short-term behavioural response by hawksbill sea turtles to elevated sea surface temperatures in the Persian/Arabian Gulf. Surface waters typically exceed 30°C for sustained periods during ... -
Concentration, composition and sources of PAHs in the coastal sediments of the exclusive economic zone (EEZ) of Qatar, Arabian Gulf
( Elsevier Ltd , 2014 , Article)Surface sediments were collected from sixteen locations in order to assess levels and sources of polycyclic aromatic hydrocarbons (PAHs) in sediments of Qatar exclusive economic zone (EEZ). Samples were analyzed for 16 ... -
Identification of Important Sea Turtle Areas (ITAs) for hawksbill turtles in the Arabian Region
( Elsevier , 2014 , Article)We present the first data on hawksbill turtle post-nesting migrations and behaviour in the Arabian region. Tracks from 90 post-nesting turtles (65 in the Gulf and 25 from Oman) revealed that hawksbills in the Arabian region ... -
