Spatial distribution, structural characterization and weathering of tarmats along the west coast of Qatar
(
Elsevier
, 2020 , Article)
Oil pollution resulting from natural and anthropogenic activities in the Arabian Gulf as well as oil residue in the form of tarmat (TM) deposited on the coast is a major environmental concern. The spatial distribution, ...
Mangrove carbon stocks and biomass partitioning in an extreme environment
(
Elsevier
, 2020 , Article)
Global inventories that show mangrove forests have rich carbon stores currently lack data from arid areas where carbon stocks may be functionally impoverished relative to humid regions. We quantified total carbon stocks ...
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 ...
New insights about the introduction of the Portuguese oyster, Crassostrea angulata, into the North East Atlantic from Asia based on a highly polymorphic mitochondrial region
(
EDP Sciences
, 2016 , Article)
It is commonly presumed that the Portuguese oyster Crassostrea angulata was introduced into the North East (NE) Atlantic from Asia. The analysis of the nucleotide sequence of a highly polymorphic non-coding mitochondrial ...
Modern problems in marine biodiversity records-illustrated by the case of the Caribbean Pelia mutica (Gibbes, 1850) confirmed in Brazil
(
Cambridge University Press
, 2016 , Article)
This report confirms the presence of Pelia mutica in Brazil, extending its range by approximately 4000 km south to the southwestern Atlantic Ocean from its most southerly recorded distribution. The presence of this small ...
Short-term behavioural responses to thermal stress by hawksbill turtles in the Arabian region
(
Elsevier
, 2014 , Article)
We present a previously unrecorded short-term behavioural response by hawksbill sea turtles to elevated sea surface temperatures in the Persian/Arabian Gulf. Surface waters typically exceed 30°C for sustained periods during ...
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 ...
Identification of Important Sea Turtle Areas (ITAs) for hawksbill turtles in the Arabian Region
(
Elsevier
, 2014 , Article)
We present the first data on hawksbill turtle post-nesting migrations and behaviour in the Arabian region. Tracks from 90 post-nesting turtles (65 in the Gulf and 25 from Oman) revealed that hawksbills in the Arabian region ...
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 ...
