Abstract 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 ability cope projected increases in ambient will depend on capacity adapt shifts climatic regimes. Here, we assessed the extent which phenological could mitigate impacts from (from 1.5 3°C air 1.4 2.3°C sea surface 2100 at our sites) four species turtles, under a...
The spatial distribution, sources and characteristics of marine litter (ML) from 36 locations spread over 12 beaches along the west coast Qatar have been assessed. A total 2376 ML items with varying sizes were found an average abundance 1.98 items/m2. order was as follows: plastics (71.4%) > metal (9.3%) glass (5.1%) paper (4.4%) fabric (4.0%) rubber (3.9%) processed wood (2.0%). Locations in south northwest coasts had significantly higher concentrations ML. Surprisingly, nearly 47% beached...
Suspended sediment concentration (SSC) in water increases temperature and turbidity, limits the photosynthesis of aquatic plants, reduces biologically available oxygen. It is important to study SSC coastal waters Arabian Gulf. Thus, this mapped between Al Arish Ghariyah northern Qatar using spectral bands MultiSpectral Imager (MSI) Sentinel-2 by calculating Normalized Difference Sediment Index Material Index. The results are studied Turbidity Modified Water mapping NDSSI showed presence a...
Although several indices have been constructed and available at the Index database (IDB) for Sentinel-2 satellite to map study earth resources, no developed oil spill. We band ratios (5 + 6)/7, (3 4)/2, (11+12)/8 3/2, (6 7)/5 using high-resolution MSI (multi-spectral instrument) visible-near infrared-shortwave infrared spectral bands of by summing-up representing shoulders absorption features as numerator located nearest feature denominator discriminate spill, demonstrate potential this...
Mangroves are important in protecting and stabilizing coastal zones. Pneumatophores of the mangrove species Avicennia marina can form a large aboveground complex aerial roots, which supporting growth low-oxygen environments. We examined relationship between tree height, girth, sediment mud content, oxygen levels with pneumatophore abundance. As sediments higher content have more anaerobic conditions due to their lower porosity, we hypothesized that abundance would be positively correlated...
The hyperarid mangrove in the Middle East is characterised by absence of rivers or freshwater inputs and one most extreme settings this ecosystem on Earth. Endemic to Qatar's mangroves, a Palaemon shrimp uniquely confined sole site Arabian Gulf. Within these channels, we unveiled brine groundwater sources exceeding 70 ppt salinity, contrasting local marine standard 42 ppt. Concurrently, mysid species typically linked salt pans coexists. Stable isotopic analysis implied existence...
Projected climate change is forecasted to have significant effects on biological systems worldwide. Marine turtles in particular may be vulnerable, as the sex of their offspring determined by incubating temperature, termed temperature-dependent determination. This study aimed estimate historical, and forecast future, primary ratios hawksbill turtle Eretmochelys imbricata hatchlings at an important nesting ground northeastern Qatar. Incubation temperatures from Arabian/Persian Gulf were...
Abstract The Exclusive Economic Zone (EEZ) of Qatar is a rapidly developing region within the Arabian Gulf, where monitoring changes in benthic biodiversity and its functioning needed. influence mangroves seasonality on nearshore subtidal molluscan diversity at three distinct khors (nearshore tidal bays) – natural (Al Dhakhira), planted Mafyar) no-mangroves (Dawhat Zekreet) are investigated this study. This study concludes that even sub-tidal area influenced by mangroves, increase molluscs...
New generic diagnoses are given for Paracleistostoma arabicum and Cleistostoma kuwaitense, crabs from the Arabian Gulf belonging to Camptandriinae. A modified key based on Manning Holthuis (1981) is constructed separate these new genera other members of subfamily. In addition, descriptions provided first zoeal stage 6 intertidal brachyurans Qatar.
The present contribution outlines a first record of 5 encountered terrestrial gastropods new to Qatar. preliminary account these species and their zoogeographical origins are discussed. belong 4 families: Subulinidae, with 2 genera, Zootecus Allopeas; Polygyridae, 1 genus, Polygra; Hygromiidae, Monacha; Helicidae, Eobania.
Oil pollution resulting from natural and anthropogenic activities in the Arabian Gulf as well oil residue form of tarmat (TM) deposited on coast is a major environmental concern. The spatial distribution, chemical composition weathering pattern along west Qatar has been assessed based TM samples collected 12 coastal regions. range distribution 0-104 g m-1 with an average value 9.25 m-1. Though current level thirty-fold lesser than that was found during 1993-1997 (average 290 m-1), similar....
Remote sensing of spectrally active Chlorophyll-a (Chl-a) in the gulf water an arid region is important to understand spatial and temporal variations phytoplankton biomass water. This study characterizes spectral absorption Chl-a detects maps Al Arish–Al Ghariyah coastal northern Qatar using data Hyperion EO-1, MultiSpectral Instrument (MSI) Sentinel-2, Operational Land Imager (OLI) Landsat-8 satellites. The image spectra showed band absorptions near 450 475 nm blue around 640, 730, 760, 830...
