Academic Press, Inc., San Diego, p. 5-385. Morphology and taxonomy of Skeletonema costatum. This phenomenon accounts for the genetic stability of S. costatum in culture and for the deficiency of heterozygotes in natural populations, and has important implications far the life history of this species. As in the previous case, some experiments were performedwithcells preincubated with 1,UM NaNO3for 4hr. The nursery pond should have at least one gate installed with a fine screen (1 mm mesh size) to prevent predators and competitors from entering (Fig. Due to the unique antibacterial properties, silver nanoparticles (AgNPs) have been widely used in commercial applications. This study evaluated the growth stimulatory effect of low-frequency ultrasound on an ecologically and economically important marine diatom, Skeletonema costatum. 27: 514-524.
