“…Macroalgae abundance was obtained as dry biomass (g) of each macroalgae species. Identification was done using the taxonomic keys and local checklists (De Clerck and Coppejans 1996;Sohrabipour and Rabiei 1999;Sohrabipour and Rabiei 2007;Sohrabipour et al 2004;Trono 2003;Jha et al 2009;Braune 2011) to the lowest possible taxonomic level. The names of species and their classifications were validated with AlgaeBase and updated when necessary.…”

This study investigates the spatial and temporal variation of intertidal macroalgae along the eastern coasts of Qeshm Island, Persian Gulf, Iran. Monthly sampling of abundance, biomass, richness and diversity of macroalgae at three intertidal levels was carried out at two different sites during 1 year. The samples were collected every month using quadrats (0.5 × 0.5 m) from October 2012 to September 2013. The species dry weight was applied to examine changes in biomass and assemblage composition of intertidal macroalgae using univariate and multivariate analyses. A total of 42 seaweed species (10 Chlorophyta, 9 Phaeophyceae, and 23 Rhodophyta) were identified. The results confirmed a temporal pattern in the growth of the algal species which also showed a biomass zonation pattern from upper to lower intertidal. The annual mean biomass of macroalgae was highest in winter (29.3 ± 9.8 g dry wt m−2 ) and the lowest in autumn (17.3 ± 13.5 g dry wt m−2 ). The annual dominant species by biomass was Padina sp. followed by Padina australis. The most common species in the area, during the sampling period include Ulva intestinalis, Ulva lactuca, Palisada perforata and Padina sp. According to the similarity percentages analysis (SIMPER), the species Ulva intestinalis, Dictyosphaeria cavernosa (Chlorophyta), Padina australis (Phaeophyceae), Champia spp., Centroceras clavulatum and Palisada perforata (Rhodophyta) were responsible for the most dissimilarity of species composition between four seasons during the sampling period. BIOENV analysis indicated that the main environmental factors structuring macroalgal community at the study area were TDS and pH. The simple macroalgae community on the eastern coast of Qeshm Island and absence of slow-growing perennial macroalgae, such as members of the Sargassaceae, known from the lower shore at other intertidal localities along the island's coast might relate to the predominantly unsuitable sandy-stony substrates unsuitable for their colonization and the unfavourable impact upon them of urbanization.

“…This coastline occurs within the geographical limits of 20°00'-24°45'N and 68°00'-78°30'E. It is 1,650 km long with 164,200 km 2 continental shelf (Jha et al, 2009). It extends in the form of four major coastal ecologic components: i) Kori creek ii) Gulf of Kachchh iii) Saurashtra coast from Okha to Porbandar and iv) Gulf of Khambhat.…”

“…A sampling point along the rope is marked depending on the gradient and exposure of intertidal and subtidal areas. In Saurashtra coast, the tidal amplitude is very high as compared to other parts of the western coast and the entire east coast of India (Jha et al, 2009). Growth of seaweeds in intertidal and shallow subtidal regions can be easily observed in this area as the spring tides expose the intertidal area up to a maximum length of one km (Jha et al, 2009).…”

“…The Saurashtra coast, which runs for an approximate length of 985 km, is characterized by rocky, sandy and muddy intertidal zones, harbouring rich and varied flora and fauna (Gohil and Kundu, 2012). The Gulf of Kachchh (GoK) is the largest coastal habitat in the Gujarat coastal area and contains 42 islands (Jha et al, 2009). It has an approximate length of 1,000 km and is delimited in the north by the Kachchh region and in the south by the Saurashtra region.…”

Many species of phaeophyta are found at Dwarka and at the Bet-Shankhodhar coast, Gujarat, India. For the study of Iyengaria stellata, the shore platform and reef flat were divided into three sections: Dwarka in i) North, ii) Centre and iii) South sections and Bet-Shankhodhar in i) West, ii) Centre and iii) East sections. I. stellata was monitored based on systematic random sampling for two years (April, 2013 to February, 2015). In the months of December and February, I. stellata was recorded with high frequencies of reef, flat zones and shore platforms. When compared to shore platform, the frequency of I. stallata was highest in coral reef and flat zones. This study supports that reef flat is very suitable for growth of I. stellata. I. stellata’s growth cycle corresponds with local winter season.

Padina is rolled-blade-shaped marine brown algae that often have overgrown and has been well explored for its medicinal qualities. The various species of Padina release a wide range of promising chemical components as part of their chemical defense systems. In this context, a finding was conducted to explore the bioactive compounds using exceptionally sophisticated analytical techniques, such as high-performance thin-layer chromatography. Microchemical and biochemical derivatization was used in the investigation to confirm multi-class bioactive molecules and the antioxidant activity of the separated band. Microchemical derivatization ascertained the appearance of miscellaneous lipophilic substances, essential oils, volatile compounds, coumarin, and bitter principles. To determine the chemical standard of these algae, the qualitative (microchemical) screening of phytochemicals associated with flexible high-performance thin-layer chromatography was utilized. Moreover, biochemical derivatization, which generates a spectacular white band with a purple background to appear on the chromatogram, substantiates the antioxidant activity of a particular band.These results proffer a chromatographic profile of the antioxidant capability of three species of Padina's bioactive components, which will create the necessary information for the standardization and identification of marine algae. Mass spectrometry results revealed the presence of phytol compound from the diterpenoid class, which has antioxidant potential.
