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 ...
Diversity of benthic macrofauna and physical parameters of sediments in natural mangroves and in afforested mangroves three decades after compensatory planting
(
Springer
, 2018 , Article)
Mangroves in the Arabian Gulf are under pressure from land use change, leading to compensatory planting at sites without
natural mangroves. In this study, we examine the potential long-term success of this form of ...
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 ...
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 ...
Artisanal fishing of spiny lobsters with gillnets — A significant anthropic impact on tropical reef ecosystem
(2015 , Article)
Abstract Artisanal fishing activity with gillnets to capture the spiny lobster is a common practice along the coastal reefs of Brazil. This research aims to understand the impact that this artisanal fishing practice is ...
Extending the southern range of four shrimps (Crustacea: Decapoda: Stenopodidae, Hippolytidae and Alpheidae) in southwestern Atlantic (27oS) and confirming the presence of Mediterranean Stenopus spinosus Risso, 1827 in Brazil
(
Zootaxa
, 2015 , Article)
In subtidal zones, certain shrimp species with cryptic behaviour represent a gap in the biodiversity description in many places in the world. This study extends the southern limit of Stenopus hispidus (Oliver, 1811), Alpheus ...
The maxima in northerly wind speeds and wave heights over the Arabian Sea, the Arabian/Persian Gulf and the Red Sea derived from 40 years of ERA5 data
(
Springer
, 2020 , Article)
Recent studies point out the importance of northerly winds and waves in the Arabian Sea, especially those due to shamal and makran events in addition to the northeast monsoon system. We have analyzed climatology and trends ...
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 ...

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 ...
A 51 ka sedimentary sequence in a seamount basin, Eastern Arabian Sea: Records for paleoceanographic and paleoclimate conditions
(
Elsevier
, 2022 , Article)
A 5.4 m thick sediment core at ∼ 517 m water depth from a seamount basin off the Goa coast in the Eastern Arabian Sea (EAS) is examined for the mineral magnetic, carbonate and organic carbon variability. The 51 ka BP dated ...
