Consequences of marine barriers for genetic diversity of the coral-specialist yellowbar angelfish from the Northwestern Indian Ocean
(
John Wiley and Sons Ltd
, 2019 , Article)
Ocean circulation, geological history, geographic distance, and seascape heterogeneity play an important role in phylogeography of coral‐dependent fishes. Here, we investigate potential genetic population structure within ...
Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome
(
Springer Verlag
, 2019 , Article)
Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current ...
Microbial community composition and dolomite formation in the hypersaline microbial mats of the Khor Al-Adaid sabkhas, Qatar
(
Springer Tokyo
, 2019 , Article)
The Khor Al-Adaid sabkha in Qatar is among the rare extreme environments on Earth where it is possible to study the formation of dolomite-a carbonate mineral whose origin remains unclear and has been hypothetically linked ...
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 ...
PAH concentrations and exposure assessment from house dust retained in air-conditioning filters collected from Greater Doha, Qatar
(
Springer Netherlands
, 2019 , Article)
Polycyclic aromatic hydrocarbons (PAHs) bound in dust retained in air-conditioning unit filters from 13 households in Greater Doha, Qatar, were quantified using GC–MS spectrometry. The median concentrations of ∑16PAH and ...
An integrated approach for produced water treatment using microemulsions modified activated carbon
(
Elsevier Ltd
, 2019 , Article)
In this study, the physical and chemical characterization of produced water was done followed by treatment through sand filtration coupled with activated carbon microemulsion modified activated carbon techniques. The results ...
Development of a liquid chromatography-quadrupole-time-of-flight-mass spectrometry based method for the targeted and suspect screening of contaminants in the pearl oyster Pinctada imbricata radiata
(
Elsevier Ltd
, 2019 , Article)
An analytical method was developed for the target and suspect screenings of contaminants in pearl oyster tissues. - 2019 Elsevier LtdA rapid method based on solvent extraction followed by direct injection in liquid ...
Global change effects on plant communities are magnified by time and the number of global change factors imposed
(
National Academy of Sciences
, 2019 , Article)
Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure ...
Oil pollution in the Eastern Arabian Sea from invisible sources: A multi-technique approach
(
Elsevier Ltd
, 2019 , Article)
The Eastern Arabian Sea (EAS) is affected by oil pollution, as often evidenced by the presence of tarballs along the West Coast of India (WCI). Tarball samples collected during May 2017 along the Goa coast were subject to ...
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 ...
