Using vertebrate environmental DNA from seawater in biomonitoring of marine habitats
(
Wiley
, 2019 , Article)
Conservation and management of marine biodiversity depends on biomonitoring of marine habitats, but current approaches are resource‐intensive and require different approaches for different organisms. Environmental DNA ...
Mercury accumulation in Lethrinus nebulosus from the marine waters of the Qatar EEZ
(
Elsevier
, 2017 , Article)
Total mercury (THg) and methylmercury (MeHg) were recorded in the commercial demersal fish Lethrinus
nebulosus, caught from six locations in Qatar EEZ (Exclusive Economic Zone). Concentrations of THg decreased
in 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 ...
Characteristics and sources of anthropogenic and biogenic hydrocarbons in sediments from the coast of Qatar.
(
Elsevier
, 2017 , Article)
Surface sediment samples from the coastal zone of Qatar were collected and analyzed to determine the characteristics, and sources of anthropogenic and biogenic hydrocarbons. The main compounds in these surface sediments ...
Geochemical composition of dust from Qatar peninsula
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
Atmospheric dust samples have been collected from different areas in Qatar and analyzed for major and trace element composition. This region of the Arabian Gulf represents an area largely affected by dust from natural and ...
Population structure of marine turtles in coastal waters of Qatar
(
Inter-Research Science Publishing
, 2015 , Article)
Knowledge of the interrelationships between habitats and life-stage development in marine turtles requires an understanding of recruitment, size and age at maturity, sex ratios, growth and sexual development rates, ...
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 ...
Benthic surveys of the historic pearl oyster beds of Qatar reveal a dramatic ecological change
(
Elsevier
, 2016 , Article)
The study aimed to confirm the presence of historic oyster banks of Qatar and code the biotopes present. The research also collated historical records and scientific publications to create a timeline of fishery activity. ...
Spatio-temporal distribution and sources identifications of polycyclic aromatic hydrocarbons and their alkyl homolog in surface sediments in the central Arabian Gulf
(
Elsevier B.V.
, 2019 , Article)
The quantitative analysis of 18 parents and their alkyl homologs was performed in sediment samples from the central Arabian Gulf (Gulf) around Qatar Peninsula in six sequential seasons, winter 2014 to spring 2015, at 21 ...
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 ...
