(
wiley online library
, 2010 , Article)
Detailed petrographic studies of Recent dolomites from the coastal sabkha of Abu Dhabi using SEM and Energy Dispersive X-ray (EDX) analyses indicate that most of the dolomite started to form in " micro-niches" (i.e. small ...
Methylmercury bioaccumulation among different food chain levels in the EEZ of Qatar (Arabian Gulf)
(
Elsevier
, 2020 , Article)
Methylmercury (MeHg) concentrations in three different species from different trophic levels with different amounts of Hg exposures were determined for the first time in the EEZ of Qatar. Sampling was conducted during ...
Adaptation of sea turtles to climate warming: Will phenological responses be sufficient to counteract changes in reproductive output?
(
John Wiley and Sons Inc
, 2024 , Article)
Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ...
Burrowing crabs in arid mangrove forests on the southwestern Arabian Gulf: Ecological and biogeographical considerations
(
Elsevier B.V.
, 2020 , Article)
Many species of mangrove crabs are essential in the formation of mangrove ecosystems, and the bioturbation resulting from the excavation of their underground chambers is directly correlated with substrate oxygenation and ...
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 ...
