Many reefs have shifted from coral and fish dominated habitats to less productive macroalgal dominated habitats, and current research is investigating means of reversing this phase shift. In the tropical Pacific, overfished reefs with inadequate herbivory can become dominated by the brown alga Sargassum polycystum. This alga suppresses recruitment and survival of corals and fishes, thus limitin...

The occurrence of oxidative stress during the sperm freeze-thaw cycles affects the sperm parameters and eventually leads to a decrease in its reproductive potential. Sperm protection against oxidative reactions during freezing is done by antioxidants. Since the selection of a suitable sperm cryopreservation bank is effective in maintaining acceptable reproductive potential and motility of sperm...

Seaweed has been gaining global interest in agriculture for the development of marine-based plant biostimulants. This research aimed to study effect three different liquid extracts Sargassum sp., acidic, alkaline, and water extract, on germination early growth maize evaluate phytohormones content responsible growth. Phytohormones including Indole-3-acetic acid (IAA), gibberellins (GA), kinetin ...

Seaweeds are large-scale multicellular marine algae categorized based on color as Chlorophyceae, Rhodophyceae, and Phaeophyceae. No information has been provided the conditions affecting production of mesoporous activated carbon from one member described aquatic plants, namely Sargassum sp. Therefore, this study aimed to determine impact main factors their interactions sp.-derived manufactured ...

This work aims to characterize biosorbent materials based on seaweed present on the littoral of Baixada Santista (São Paulo state, Brazil), and test their adsorption properties to remove heavy metal cations (Co+2, Pb+2, and Cd+2) in water, aiming its future application situ remediations degraded ecosystems. Three types of nat...

Thirty-two species of Egyptian marine algae of Chlorophycophyta, Phaeophycophyta and Rhodophycophyta collected from the Mediterranean (17 spp.) and Red (15 spp.) Seas has been analyzed for their content of iodine. ' Distribution of iodine in Egyptian marine algae showed noticeable local differences. The highest values were obtained in the species collected from the Mediterranean Sea. Iodine con...
