Composition, Habitats, Seasonal Changes and Productivity of Macroalgae in Grays Harbor Estuary, Washington

摘要: Twenty-nine taxa of macroalgae were collected from the Grays Harbor Estuary, Washington, 17 April 1980 to 4 June 1981. Outer (oceanic) sites contained higher numbers species than located in inner portion estuary. Macroalgae found several habitats including attached boulders, logs, tree roots, other algae, and angiosperms, as mats sand, drift.Fucus distichus ssp.edentatus andEnteromorpha intestinalis occurred at greatest number throughout year. The standing stock perennialFucus remained relatively consant, while that anE. andBlidingia minima var.subsalsa complex showed a significant peak between late spring early summer well winter minimum. occurrence most was highly seasonal. Net productivity rates for abundant macroalgal moderate high relative published algae North American estuaries. It is concluded that, although inconspicuous, may represent an important contributor organic carbon estuarine system.
