Fucoxanthin contents of four species of brown seaweeds (Dictyota indica, Padina tenuis, Colpomenia sinuosa and Iyengaria stellata) from intertidal zone of Qeshm Island, Persian Gulf were assessed in summer and winter of 2016. In addition, some physicochemical properties (pH, temperature, salinity and conductivity) of seawater were monitored on the same time. The antibacterial activity of algal ...

Recently, Korean people are consuming seaweeds almost 3.5 times more now than three decades ago. It is well known that seaweeds contain lots of soluble dietary fiber in addition to micronutrients such as beta-carotene, iodine and some bioactive components. Seaweeds are considered to be effective for preventing chronic diseases including obesity, diabetes mellitus, atherosclerosis, cancer or con...

BACKGROUND Ulva genus, an edible seaweed, and an important food source in many south-east Asian countries is also recognized by its synonymous name as Enteromorpha. OBJECTIVES This study was carried out to evaluate antioxidant activity, contents of total phenolics, and flavonoids of methanolic extracts of edible green seaweeds including Ulva clathrata (Roth) C. Agardh and three samples of Ulv...

BACKGROUND/OBJECTIVES Abundant consumption of seaweeds in the diet is epidemiologically linked to the reduction in risk of developing cancer. In larger cases, however, identification of particular seaweeds that are accountable for these effects is still lacking, hindering the recognition of competent dietary-based chemo preventive approaches. The aim of this research was to establish the antipr...

BACKGROUND The introduction of exotic species can have serious consequences for marine ecosystems. On the shores of the Cantabrian Sea (North of Spain) there are no routine examinations of seaweeds that combine molecular and morphological methods for early detection of exotic species making it difficult to assess in the early stages their establishment and expansion processes as a result of ant...

We studied possible interactions among invertebrate species and algal assemblages in a shallow sublittoral community of the Mediterranean Sea using a 2-step approach. First, we analysed the general pattern by correlation analysis. Thereafter, we experimentally assessed cause–effect relationships between the species or assemblages that were clearly related in the correlation study. The abundance...

Models of benthic community dynamics for the extensively studied, shallow rocky ecosystems in eastern Canada emphasize kelp-urchin interactions. These models may bias the perception of factors and processes that structure communities, for they largely overlook the possible contribution of other seaweeds to ecosystem resilience. We examined the persistence of the annual, acidic (H2SO4), brown se...

We evaluated the levels of heavy metals and arsenic (As) species in 11 different types seaweed collected from major coastal cities Korea. The concentration ranges were as follows: cadmium (0.023–0.232 mg/kg fresh weight [fw]), lead (0.025–0.222 fw), with most meeting international regulations for edible seaweeds. amount total As, however, was high, ranging 1.020 to 20.525 fw. Especially case Sa...

Knowledge on the seaweeds of eastern Sorsogon in Philippines is uneven. Not only among areas high seaweed diversity but locals there have interacted with for ages. Despite seaweeds’ assumed importance to Sorsoganon, ethnobotanical records are missing. In this study, we documented traditional knowledge use and determined rate transmission Sorsogon. Vernacular names modes preparation were given 1...
