Three size classes of Capitella capitata (Type I ) were fed 4 size ranges of detritus particles derived from red seaweed Gracilaria foliifera. Growth was generally reduced when only the largest particle-size range (150 to 250 pm) was available, and the effect was most pronounced for small worms. Worms lost weight when fed fecal pellets comparable in size to the largest particles of seaweed detr...

Macroalgal blooms develop during the spring-summer period in the Barnegat Bay–Little Egg Harbor Estuary, a highly eutrophic coastal lagoon in New Jersey, and these blooms are detrimental to seagrass habitat in the system. Recurring blooms of drifting red and green macroalgae (e.g., Gracilaria tikvahiae and Ulva lactuca) attenuate or block light transmission to seagrass beds and also produce ext...

OBJECTIVE In vitro antioxidant activities of three selected Indian seaweeds viz., Halimeda tuna (H. tuna), Turbinaria conoides (T. conoides) and Gracilaria foliifera (G. foliifera) were evaluated. METHODS Total antioxidant activity, total phenolic content, and reducing power of crude methanol and diethyl ether extracts were determined. RESULTS Total phenolic content and total antioxidant ac...

Bone remodeling, a physiological process characterized by bone formation by osteoblasts and bone resorption by osteoclasts, is important for the maintenance of healthy bone in adult humans. Osteoclasts play a critical role in bone erosion and osteoporosis and are bone-specific multinucleated cells generated through differentiation of monocyte/macrophage lineage precursors. Receptor activator of...

The red alga Gracilaria salicornia (c. Agardh) E. Y. Dawson was introduced intentionally to two reefs on O'ahu, Hawai'i, in the 1970s for experimental aquaculture for the agar industry. Some 30 yr later, this species has spread from the initial sites of introduction and is now competing with native marine flora and fauna. The goals of this study were to quantify various aspects of G. salicornia...
