Associated effects of storage and mechanical pre-treatments of microalgae biomass on biomethane yields in anaerobic digestion
(
Elsevier
, 2016 , Article)
The pre-treatment of microalgae cell walls is known to be a key factor to enhance methane (CH4) yields during anaerobic digestion. This study investigated the combined effects of two different biomass storage methods and ...
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 ...
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 ...
Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
(
Springer International Publishing
, 2016 , Article)
The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ...
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 ...
Consequences of marine barriers for genetic diversity of the coral-specialist yellowbar angelfish from the Northwestern Indian Ocean
(
Wiley
, 2019 , Article)
© 2019 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd. Ocean circulation, geological history, geographic distance, and seascape heterogeneity play an important role in phylogeography of coral-dependent ...
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 ...
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 ...
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 ...
Modeling sediment transport in Qatar: Application for coastal development planning.
(
Wiley
, 2018 , Article)
Hydrodynamics and sediment transport are key physical processes contributing to habitat structure within the marine environment. Coastal development that results in the alteration of these processes (e.g., changing water ...
