Toxic properties are more often associated with microalgal blooms than with macroalgal blooms, although herbivore deterrents are well known in macroalgae, and inhibition of invertebrate larval development by extracts from Ulva spp. has been suggested. This study was prompted from our observation that substantial discoloration of seawater occurred in small bays after mass desiccation‐induced mortality of Ulvaria obscura (Kützing) Gayral. We examined the effects of extracts from Ulva fenestrata…

Exudates of the green alga Ulvaria obscura (Kützing) affect larval development of the sand dollar Dendraster excentricus (Eschscholtz) and the Pacific oyster Crassostrea gigas (Thunberg)

Results indicate that compounds released by U. obscura affect development differently between invertebrate species and among developmental stages, as well as changes in structure and metabolic activity at different life history stages.

Differential toxic effects of Ulva lactuca (Chlorophyta) on the herbivorous gastropods, Littorina littorea and L. obtusata (Mollusca)

It is concluded that the water‐soluble, toxic exudate produced by U. lactuca in response to herbivory had allelochemical properties, and may contain a cleavage product (acrylic acid) of dimethylsulfoniopropionate or reactive oxygen species (i.e., H2O2).

Experiments comparing the growth rates, responses to desiccation, photoacclimation, and grazer preference of U. obscura and Ulva revealed that Ulvaria was capable of faster growth, had higher rates of photosynthesis, and was more Desiccation tolerant than Ulvia.

The negative effects of these secondary metabolites on potential foulers, in conjunction with data demonstrating larval avoidance of dictyol-covered surfaces, suggest that these compounds could function as chemical defenses against fouling, and could select for larvae that avoid hosts producing these metabolites.

The green alga Ulva lactuca is the dominant green sea weed found in estuaries of the northwestern Atlantic and may be an important component of the base of the estuarine fish food web, but casual observations of fresh thalli deposited in the intertidal zone reveal relatively little evidence of animal associations.
