The effect of density in larval rearing of the pullet carpet shell Venerupis corrugata (Gmelin, 1791) in a recirculating aquaculture system
(
John Wiley & Sons Ltd
, 2014 , Article)
The pullet carpet shell Venerupis corrugata is an economically valuable species in several European countries, however, nowadays stocks are under high fishing pressure. Hatchery production of juveniles for release is a ...
Is metal contamination responsible for increasing aneuploidy levels in the Manila clam Ruditapes philippinarum?
(
Elsevier
, 2017 , Article)
The present study assessed the metal genotoxicity potential at chromosome-level in the bivalve Ruditapes philippinarum collected along different areas of the Tagus estuary. Higher levels of aneuploidy on gill cells were ...
Extreme 15N Depletion in Seagrasses
(
Springer New York LLC
, 2016 , Article)
Seagrass beds form an important part of the coastal ecosystem in many parts of the world but are very sensitive to anthropogenic nutrient increases. In the last decades, stable isotopes have been used as tracers of ...
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 ...
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 ...
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 ...
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 ...
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 ...
A MALDI-TOF study of bio-remediation in highly weathered oil contaminated soils
(
Elsevier
, 2018 , Article)
We have shown that Bacillus cereus is dominating the bacterial population at three polluted oil-industry sites
where weather and soil conditions are extreme in terms of temperature, UV-radiation and salinity. A minor ...
