Factors determining the degree of dietary generalism versus specialism are central in ecology. Species that are generalists at the population level may in fact be composed of specialized individuals. The optimal diet theory assumes that individuals choose diets that maximize fitness, and individual specialization may occur if individuals' ability to locate, recognize, and handle different food ...

The biosorption of arsenic (As) with macroalgae has aroused much interest as a clean and low-cost technology. To evaluate by Chondracanthus chamissoi Cladophora sp., approximately 5 kg algae was collected from Huanchaco’s beach Sausacocha lake (Huamachuco), La Libertad. As carried out in four column systems, 2 g pellets each, circulating solutions 0.25 1.25 ppm, respectively, at 300 mL/min cm2....

Nanomaterial is one of the recent technological advancements that attracts attention many scientists. Many advanced properties could emerge from utilization materials on this scale. Nanocrystalline cellulose (NCC) a cellulose-based nanomaterial currently gaining because its remarkable properties. NCC was prepared by removing amorphous part through acid hydrolysis. Cladophora type algae with fib...

QX disease in Sydney rock oysters (Saccostrea glomerata) is caused by the paramyxean protozoan, Marteilia sydneyi. Disease outbreaks occur during summer (January to May) and can result in up to 95% mortality. The New South Wales Department of Primary Industries has been selectively breeding S. glomerata for resistance to QX disease since 1996. Previous work suggests that this breeding program h...
