“…Sediment types in this habitat range from soft muds with high clay content to firm sands consisting largely of carbonate particles of biogenic origin (Basson et al, 1977). Mangrove-dominated habitats in the UAE range from areas with only sparse cover by small trees ( Figure 2I) to densely forested areas with some trees exceeding 5 m in height ( Figure 2G; Moore et al, 2015). The only mangrove species known to occur in the UAE is Avicennia marina, a eurythermal, euryhaline species (Basson et al, 1977;Sheppard et al, 1992).…”

“…Early mangrove mapping efforts in the UAE (e.g., Saenger et al, 2004) have been recently updated by Moore et al (2015). Three species of seagrasses occur in the region: Halodule uninervis (the dominant species), Halophila ovalis and Halophila stipulacea (Phillips, 2003).…”

“…Most attention has been focused on the coral reefs in the region, which have been negatively affected by development activities as well as thermal bleaching and harmful algal blooms (HABs) Burt, 2014;Burt et al 2011, Grizzle et al, 2016Sheppard, 2016). Other ecologically important nearshore habitats such as mangroves which occur on both UAE coasts clearly have been affected by widespread coastal development activities, but their spatial extent and condition have been little studied in recent decades (Moore et al, 2015). Similarly, other coastal habitats in the UAE such as seagrasses and pearl oyster reefs, as well as the occurrence of commercially and otherwise important taxonomic groups, including molluscs, in relation to habitat type, have received limited attention to date (EA Abu Dhabi, 2008).…”

This paper describes the results of three qualitative surveys of marine molluscs conducted in December 2010 and May 2011 and 2012 in nearshore benthic habitats along the Arabian Gulf and Gulf of Oman coasts of the United Arab Emirates. Findings are compared to historical studies, focusing on extensive surveys from the 1960s and 1970s. Molluscan species of public health significance are identified based on their potential as vectors of algal toxins in light of the recent occurrence of harmful algal blooms (HABs) in the region. Habitats sampled included intertidal sand or gravel beaches, rocks and jetties, sheltered soft-sediment flats and mangroves, and shallow subtidal coral reefs. The present study showed differences in taxonomic composition and decreased species richness of gastropods compared to a previous mollusc survey conducted in the early 1970s, reflecting the probable impacts of extensive, ongoing coastal development activities, although other environmental stressors may play a contributing role. The major habitat change found in the current survey was replacement of natural "rocky" substrates with manmade jetties and breakwaters. Of the 27 live gastropod species collected, 7 predatory or scavenging species were identified as potential biotoxin vectors: Thais savignyi, T. tissoti, T. lacera, Murex scolopax, 62 Nassarius persicus, Hexaplex kuesterianus and Rapana sp. Of the 22 live bivalve species 63 collected, the following 11 suspension-feeders were deemed to be potential vectors of HAB toxins 64 based on their body size and feeding mode: three venerid clams (Circenita callipyga, and Tivela ponderosa that are consumed locally, and Amiantis umbonella), the widespread encrusting rock oyster, Saccostrea cuccullata, also consumed locally, two pearl oyster species, Pinctada spp., the prickly pen shell Pinna muricata, the scallop Chlamys livida, the cockle Acrosterigma lacunosa, and the facultative suspension-feeding tellinids Asaphis violascens and Hiatula rosea.

“…This tree withstands severe environmental stresses [ 10 , 11 ]. It has been reported that A. marina can tolerate a very high level of salinity and temperature [ 12 ]. The survival capability of A. marina under severe environmental conditions is because of the presence of a large number of phytochemicals [ 13 ].…”

Increased problems associated with side effects and bacterial resistance of chemical drugs has prompted the research focus on herbal medicines in the past few decades. In the present investigation, the antimicrobial activity of the various parts of Avicennia marina (AM), a mangrove plant, has been evaluated. The plants were collected from the Jazan area of the Kingdom of Saudi Arabia. Primary extracts of roots, stem, leaves, fruits, and seeds were made in ethanol and fractioned in ethanol, ethyl acetate, petroleum ether, chloroform, and water. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the extracts were determined against Bacillussubtilis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. It has been observed that the chloroform extract of roots of the AM exhibited inhibitory effects against both S. aureus (MIC = 1.5 ± 0.03 mg/mL) and E. coli (MIC = 1.7 ± 0.01 mg/mL). The ethanolic extract of the AM roots has shown antibacterial activity against Pseudomonas aeruginosa (MIC = 10.8 ± 0.78 mg/mL), Bacillussubtilis (MIC = 6.1 ± 0.27 mg/mL), Staphylococcus aureus (MIC = 2.3 ± 0.08 mg/mL), and Escherichia coli (MIC = 6.3 ± 0.28 mg/mL). The leaf extract of the AM in ethyl acetate showed antibacterial activity against S. aureus and E. coli. Antifungal activity of these extracts was also investigated against Aspergillus fumigatus and Candida albicans. Ethanolic extract of roots and seeds of the AM has shown antifungal activity against Aspergillus fumigatus when applied individually. Ethanolic extract of the AM fruits has shown an inhibitory effect on the growth of Aspergillus fumigatus and Candida albicans. It is suggested that the plant extracts of AM have tremendous antimicrobial activity against a group of microbes, and this effect depends on both the plant part and the solvent used for extraction. Therefore, this plant can be considered to treat various diseases caused by antibiotic-resistant bacteria.

“…They are distributed largely in the tropical and subtropical areas between 30°N and 30°S latitude. As a habitat to rich and biologically complex species, they are one of the most productive ecosystems in the world [329], providing considerable services to human communities with ecological and economic values to protect shoreline from storms, erosion, and sedimentation [330], as well as providing nutrients for algae blooms. The protective role of mangrove forests was also recognized during Asian Tsunami of 2004 and other natural disasters such as hurricanes [331], [332].…”
