The benthic sea-silk-thread displacement of a sessile bivalve, Pinctada imbricata radiata (Leach, 1819) in the Arabian-Persian Gulf
( Public Library of Science , 2019 , Article)A number of molluscs within the Class Bivalvia are defined by their ability to secrete fine silk like threads known as byssus which are used to anchor themselves to solid substrates. With relatively few exceptions the ... -
The potential impact data of Tylosin and Enrofloxacin veterinary antibiotics on germination and accumulation in barley seed as a forage crop and good dietary sources using LC/MS-MS
( Elsevier , 2019 , Article)In this study, the phytotoxic effects caused by the exposure to five different concentrations of two veterinary antibiotics (Tylosin, and Enrofloxacin) that are commonly used for the treatment of farm animals as antibacterial ... -
Redefining the climate niche of plant species: A novel approach for realistic predictions of species distribution under climate change
( Elsevier , 2019 , Article)Climate change is increasingly affecting plant species distributions, in ways that need to be predicted. Here, in a novel prediction approach, we developed the relevant climate niche (RCN) of plants, based on thorough ... -

( Acarological Society of Iran , 2019 , Article)In this study, the genus Plegadognathus Morselli, 1981 with the species P. bonariensis. Viets, 1936) is recorded from Qatar for the first time. Diagnoses for the genus Plegadognathus and the short description of female of ... -
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 ... -
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 ... -
Geochemical investigation of Yamama crude oils and their inferred source rocks in the Mesopotamian Basin, Southern Iraq
( Taylor & Francis , 2019 , Article)Ten oil samples from the Yamama reservoirs and ten extracts of purported source rocks from sixteen wells in the Mesopotamian Basin, Southern Iraq have been analyzed using GC, GC/MS and Stable Carbon Isotope. Yamama oils ... -
Baseline concentrations of mercury species within sediments from Qatar's coastal marine zone
( Elsevier , 2019 , Article)Baseline concentration of total mercury (THg), organic extractable mercury and methylmercury (CH3Hg) concentrations in sediments from the northeastern, eastern and southeastern parts of the Arabian Gulf were assessed. ... -
Contribution of the Zubair source rocks to the generation and expulsion of oil to the reservoirs of the Mesopotamian Basin, Southern Iraq
( Taylor & Francis , 2019 , Article)The huge quantities of oil and gas reserved in the fields of southern Iraq must be matched by enough source rocks that can generate and expel equivalent amounts of hydrocarbons. This study is an attempt to evaluate the ... -
Evaluation of the source rock potential of the Unyazah Formation (late Carboniferous-Early Permian) in Dukhan Field, Qatar
( Taylor & Francis (Routledge) , 2019 , Article)Twenty samples were collected from the Unayzah Formation in three wells from Dukhan Field, Qatar. Many samples were of poor quality due to the low TOC content containing gas prone-kerogen type III and IV. The Rock-Eval ... -
BTEX, nitrogen oxides, ammonia and ozone concentrations at traffic influenced and background urban sites in an arid environment
( Elsevier , 2019 , Article)Spatial distribution of key air pollutants were studied in Doha, Qatar, over the course of two monitoring campaigns in early spring, 2016. Time-weighted averages of BTEX components (benzene, toluene, ethyl-benzene, ... -
Lysmata arvoredensis nov. sp. a new species of shrimp from the south coast of Brazil with a key to species of Lysmata (Caridea: Lysmatidae) recorded in the southwestern Atlantic
( PeerJ , 2018 , Article)Lysmata arvoredensis sp. nov. inhabits temperate waters in the south coast of Brazil and is named in tribute to the Marine Protected Area REBIO Arvoredo. This is the fourth species belonging to the genus Lysmata recorded ... -
Nesting ecology of hawksbill turtles, Eretmochelys imbricata, in an extreme environmental setting
( Public Library of Science , 2018 , Article)Relatively few details of hawksbill turtle (Eretmochelys imbricata) nesting ecology exist within the Arabian Gulf. Moreover, little is known about how their nesting dynamics compare to nesting populations throughout the ... -
Validation of Total Mercury in Marine Sediment and Biological Samples, Using Cold Vapour Atomic Absorption Spectrometry
( MDPI , 2018 , Article)A method for the measurement of total mercury (T-Hg) in environmental samples using cold vapour atomic absorption spectrometry (CV AAS) has been validated yielding a dynamic range (0.04–10.00 g/kg) and high certified ... -
Decline in oyster populations in traditional fishing grounds; is habitat damage by static fishing gear a contributory factor in ecosystem degradation?
( Elsevier , 2018 , Article)The territorial waters of Qatar once supported dense assemblages of the pearl oyster Pinctada radiata. The oysters settled on a patchy network of limestone platforms (hairãt) and provided a suite of ecosystem services to ... -
Impact of the demise mechanisms of the Cretaceous rudist buildups in the Arabian Plate on their reservoir characteristics
( Springer Berlin Heidelberg , 2017 , Article)Rudist buildups form the major oil-producing reservoirs in the Cretaceous carbonate strata of the Arabian Plate. They are the main components of the Shuaiba and Mishrif and to lesser extent, the Natih, Mauddud, Simsima, ... -
Assessment of the environmental health of an ecologically sensitive, semi-enclosed, basin - A water quality modelling approach.
( Elsevier , 2018 , Article)Semi-enclosed basins are environmentally dynamic and some of the most anthropogenically affected components of the coastal realm. They can reflect various environmental impacts, thus qualifying as natural laboratories to ... -
