Factors influencing the vertical distribution of microplastics in the beach sediments around the Ras Rakan Island, Qatar
( Springer , 2021 , Article)Microplastic (MP) pollution is an emerging environmental problem, particularly in the marine environment, and nations are concerned about this issue. In this study, an attempt has been made to investigate the vertical ... -
Faunal mediated carbon export from mangroves in an arid area
( Elsevier , 2020 , Article)The outwelling paradigm argues that mangrove and saltmarsh wetlands export much excess production to downstream marine systems. However, outwelling is difficult to quantify and currently 40–50% of fixed carbon is unaccounted ... -
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 ... -
Feminization of hawksbill turtle hatchlings in the twenty-first century at an important regional nesting aggregation
( Inter Research , 2021 , Article)Projected climate change is forecasted to have significant effects on biological systems worldwide. Marine turtles in particular may be vulnerable, as the sex of their offspring is determined by their incubating temperature, ... -
Field and laboratory investigation of tarmat deposits found on Ras Rakan Island and northern beaches of Qatar
( Elsevier , 2020 , Article)© 2018 Elsevier B.V. Beaches of Ras Rakan Island, located off the northern tip of Qatar, are extensively contaminated by highly weathered tarmat deposits. The focus of this study is to determine the possible source of the ... -
First genotoxicity assessment of marine environment in Qatar using the local Pearl oyster Pinctada radiata
( Elsevier , 2017 , Article)The Arabian Gulf countries’ marine environment has been subjected to increasing industrial development and anthropogenic pressure, leading to the growing introduction of contaminants into the marine environment, with a ... -
The first record of the Indo-Pacific benthic ctenophore Coeloplana (Benthoplana) meteoris (Ctenophora: Coeloplanidae) in the ArabianPersian Gulf
( Elsevier , 2019 , Article)This report presents the first occurrence of the Indo-Pacific benthic ctenophore Coeloplana (Benthoplana) meteoris (Thiel, 1968) in the western part of the Arabian-Persian Gulf, extending its range to 2000km, a record that ... -
Fish communities and environmental variables during dry season in Pampanga estuary (Philippines)
( Elsevier , 2020 , Article)Baseline assessment of fish communities and selected environmental variables (salinity, water temperature, water transparency, current speed, total suspended solid, chlorophyll a) was conducted in Pampanga estuary (Philippines) ... -
The fishing behaviour of Metopograpsus messor (Decapoda: Grapsidae) and the use of pneumatophore-borne vibrations for prey-localizing in an arid mangrove setting
( Cambridge University Press , 2019 , Article)This study presents the first documented observations of a brachyuran crab's proactive fishing behaviour in conjunction with mangrove pneumatophores which are employed as prey-localization devices. All ecological data were ... -
Food web structure of three Mediterranean stream reaches along a gradient of anthropogenic impact
( Springer , 2020 , Article)Anthropogenic impact can alter food web structure through changes in species interactions. In this study, we explored the food web of three Mediterranean stream reaches (two seasonal and one permanent) along an anthropogenic ... -
Formation and weathering assessment of oil-suspended sediment aggregates through a laboratory investigation.
( Springer , 2021 , Article)Formation of oil-suspended sediment aggregates (OSAs) is believed to be one of the natural cleaning processes in the marine environment. In this study, we have investigated the formation processes of OSAs under different ... -
Hitchhiking of encrusting organisms on floating marine debris along the west coast of Qatar, Arabian/Persian Gulf
( ELSEVIER , 2021 , Article)The floating marine debris (FMD) and the associated rafting communities are one of the major stressors to ecosystem services, global biodiversity and economy and human health. In this study, assemblages of encrusting ... -
Hydroacoustics to examine fish association with shallow offshore habitats in the Arabian Gulf
( Elsevier B.V. , 2018 , Article)In order to implement spatial fisheries management in the Arabian Gulf, a better understanding of the distribution of fish in relation to benthic habitats is required. To facilitate this, hydroacoustic fish surveys were ... -
Hypoxia in the central Arabian Gulf Exclusive Economic Zone (EEZ) of Qatar during summer season
( Elsevier , 2015 , Article)Abstract One of the most fascinating and unexpected discoveries during the Qatar University Marine Expeditions to the marine Exclusive Economic Zone (EEZ) of Qatar in 2000–2001, was the detection of a hypoxic water layer ... -
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 ... -
Independent effects of habitat and stream typology on macroinvertebrate communities in Mediterranean-type intermittent streams
( Associacion Espanola de Limnologia , 2019 , Article)Independent effects of habitat and stream typology on macroinvertebrate communities in Mediterranean-type intermittent streams Macroinvertebrate-based water quality assessment in temporary streams is an important yet still ... -
Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.
( Nature Research , 2019 , Article)Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates ... -
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 ... -
