Commissioned Review. Carbon: freshwater plants Commissioned Review. Carbon: freshwater plants
δ13C values for freshwater aquatic plant matter varies from −11 to −50‰ and is not a clear indicator of photosynthetic pathway as in terrestrial plants. Several factors affect δ13C of aquatic plant matter. These include: (1) The δ13C signature of the source carbon has been observed to range from +1‰ for HCO3− derived from limestone to −30‰ for CO2 derived from respiration. (2) Some...

Experimental evidence for the effects of polyphenolic compounds from Dictyoneurum californicum (Phaeophyta; Laminariales) on feeding rate and growth in the red abalone Haliotus rufescens Swainson Experimental evidence for the effects of polyphenolic compounds from Dictyoneurum californicum (Phaeophyta; Laminariales) on feeding rate and growth in the red abalone Haliotus rufescens Swainson
The effects of polyphenolic compounds from brown algae on grazing and growth rate of the California red abalone Haliotis rufescens Swainson were examined. Abalone consumed three phenolic-poor algal species, Laminaria sinclarii (Harvey) Farlow, Macrocystis pyrifera Agardh, and Nereocystis luetkeana Postels et Ruprecht (mean phenolic content = 0.52% dry mass), at a greater rate than two...
