The effect of resource subsidies on recipient food webs has received much recent attention. The purpose of this study was to measure the effects of significant seasonal seaweed deposition events, caused by hurricanes and other storms, on species inhabiting subtropical islands. The seaweed represents a pulsed resource subsidy that is consumed by amphipods and flies, which are eaten by lizards an...

Hepatitis C virus (HCV) has infected 3% of the population worldwide and 20% of the population in Egypt. HCV infection can lead to hepatocellular carcinoma and death. The presently available treatment with interferon plus ribavirin, has limited benefits due to adverse side effects. Seaweeds have become a major source of new compounds to treat viral diseases. This work aimed to study the effect o...

The seaweeds are economically valuable resources, used as food, fodder, fertilizer and medicine and thus useful to mankind in many ways. In the present study, Kappaphycus alvarezii, a marine alga, has been analysed for the presence of bioactive products using three solvent extracts. Antimicrobial activity was also done using the same extracts of seaweed. The results revealed that the selected s...

The effect of environmental change on ecosystems is mediated by species interactions. Environmental change may remove or add species and shift life-history events, altering which species interact at a given time. However, environmental change may also reconfigure multispecies interactions when both species composition and phenology remain intact. In a Caribbean island system, a major manifestat...

The lack of a genetic transformation system that allows integration of a foreign gene into the genome is a serious hindrance to progress in biological research on seaweeds. In contrast, physiological research in seaweeds has a long history of focus on the establishment of cell polarity and multicellularity (Brownlee and Bouget, 1998; Hable and Hart, 2010). Today, nuclear genomes have been recen...

BACKGROUND: Sustainable agriculture today plays an important role in the utilization of organic matter and biofertilizers to eliminate or reducing chemical fertilizer, promoting fertility and preserving biological activities, enhancing the health of agricultural products and reducing environmental damage. OBJECTIVES: Current research was conducted to asse...

The ability to recognize and respond to the presence of microbes is an essential strategy for seaweeds to survive in the marine environment, but understanding of molecular seaweed-microbe interactions is limited. Laurencia dendroidea clones were inoculated with the marine bacterium Vibrio madracius. The seaweed RNA was sequenced, providing an unprecedentedly high coverage of the transcriptome o...

Seaweeds and soy are two commonly eaten foods in Asia. Both have been reported to affect thyroid function, seaweed because of its iodine content and soy because of its goitrogenic effect. Twenty-five healthy postmenopausal women (mean age 58 years) completed a double-blinded randomized crossover study. Ten capsules (5 g/day) of placebo or seaweed (Alaria esculenta), providing 475 microg of iodi...
