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 ... -
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 ... -
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 ... -
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 ... -
Insights into molecular features of venerupis decussata oocytes: A microarray-based study
( Public Library of Science , 2014 , Article)The production of Venerupis decussata relies on wild seed collection, which has been recently compromised due to recruitment failure and severe mortalities. To address this issue and provide an alternative source of seed, ... -
Two-stage cultivation of a Nannochloropsis mutant for biodiesel feedstock
( Springer Verlag , 2015 , Article)Optimization of mass microalgae cultures is required for the efficient production of biodiesel feedstock in terms of total fatty acid (TFA) content and a conducive fatty acid profile. A mutant strain of Nannochloropsis sp. ... -
Acutodesmus obliquus as a benchmark strain for evaluating methane production from microalgae: Influence of different storage and pretreatment methods on biogas yield
( Elsevier , 2015 , Article)Acutodesmus obliquus (SAG 276-1), a microalga with a resistant cell wall, was chosen as a benchmark strain for testing the effect of storage and pretreatment methods on methane yields during anaerobic digestion. A. obliquus ... -
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 ... -
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 ... -
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 ... -
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 ...
