Basic assessment of Portunus segnis (Forskål, 1775) – A baseline for stock management in the Western Arabian Gulf
( Elsevier , 2016 , Article)Portunus segnis (Forskål, 1775) is the representative species of the Portunus pelagicus (Linnaeus, 1758) complex described as inhabiting the Arabian Gulf. It represents one of the most important decapod resources within ... -
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. ... -
The biological effects of chemical contaminants in the Arabian/Persian Gulf: A review
( Elsevier , 2020 , Article)© 2019 Elsevier B.V. The Arabian Gulf is a shallow sea naturally exposed to extreme conditions of temperature and salinity due to its location, semi-enclosed nature, bathymetry and restricted circulation. Compared to open ... -
Characteristics and renewal of zooplankton communities under extreme environmental stresses in the oligotrophic hypersaline Arabian Gulf
( Elsevier , 2022 , Article)Impacts of the exceptionally high temperature and salinity on species composition, abundance, biomass and diversity of zooplankton communities were examined in the central Arabian (Persian) Gulf in late winter and summer ... -
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 ... -
