On northeastern Pacific coasts, Ulvaria obscura is a dominant component of subtidal “green tide” blooms, which can be harmful to marine communities, fisheries, and aquaculture facilities. U. obscura is avoided by herbivores relative to many other locally common macrophytes, which may contribute to its ability to form persistent blooms. We used a bioassay-guided fractionation method to experimentally determine the cause of reduced feeding on Ulvaria by echinoderms, molluscs, and arthropods. Our… 
Effects of dopamine, a compound released by the green-tide macroalga Ulvaria obscura (Chlorophyta), on marine algae and invertebrate larvae and juveniles
TLDR
It is concluded that the large-scale release of dopamine by U. obscura following stressful environmental conditions could significantly affect co-occurring species in intertidal pools as well asintertidal and shallow subtidal marine communities where the alga can form large blooms.
Dopamine release by Ulvaria obscura (Chlorophyta): environmental triggers and impacts on photosynthesis, growth, and survival of the releaser
TLDR
Desiccation, which is coupled with dopamine release, is associated with the deterioration and death of some, but not all, tissues in Ulvaria, indicating that a net fitness benefit to release dopamine following desiccation cannot be ruled out.
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)
TLDR
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.
Plant signals during beetle (Scolytus multistriatus) feeding in American elm (Ulmus americana Planch)
TLDR
The objective was to understand elm responses to beetle feeding in the absence of the fungus to identify potential resistance mechanisms and differences were noted between susceptible and resistant elms that provide new understanding of plant defenses.
Anti-grazing activity and seasonal variation of dimethylsulfoniopropionate-associated compounds in the invasive alga Codium fragile ssp. tomentosoides
TLDR
It is suggested that DMS and AA contribute to the avoidance of C. fragile ssp.

TLDR
It is suggested that the pattern of response to variation in dopamine concentration, manifested by early larvae of both species, is similar to that observed at different concentrations of microalgae.
Ecological and physiological controls of species composition in green macroalgal blooms.
TLDR
Ulva specimens grew faster than Ulvaria in intertidal chambers but not significantly faster in subtidal chambers, and Ulva was better able to acclimate to a high-light environment and was more tolerant of low salinity than ULVaria, suggesting that nitrogen availability could affect species composition.
Management of natural Ulva spp. blooms in San Quintin Bay, Baja California: Is it justified?
According to Zertuche-González et al. (2009), Ulva spp. blooms, favored by oyster cultivation, are likely displacing subtidal meadows of Zostera marina in San Quintin Bay, Baja California. The
Spatiotemporal sex ratios of a dioecious marine green alga Monostroma latissimum (Kütz.) Wittr.
TLDR
There seems to be no environmental factor that differentially influences the in-situ survival of male or female gametophytes in rocky intertidal seaweed Monostroma latissimum.

Activated defense systems in marine macroalgae: evidence for an ecological role for DMSP cleavage
TLDR
The data suggest that DMSP may function as a precursor in an activated defense system in diverse species of temperate macroalgae and may possibly contribute to the widespread success of the Ulvophyceae.
Dimethylsulfide Release during Macroinvertebrate Grazing and Its Role as an Activated Chemical Defense
TLDR
DMS functions as a potent feeding deterrent against sea urchins Strongylocentrotus droebachiensis at a wide range of concentrations and functions as an herbivore deterrent, causing species that produce DMSP to be avoided by some herbivores.
Are Tropical Plants Better Defended? Palatability and Defenses of Temperate vs. Tropical Seaweeds
TLDR
The results support the general hypothesis that tropical seaweeds have stronger chemical defenses than temperate seaweeds, and some species ex- hibited significant, between-population variation in herbivore resistance on a local scale.

TLDR
It is suggested that a carbon imbalance, initiated by rising water temperatures and declining water‐column N; thermal stress; and biological factors (competition, grazing) all contribute to the recurrent summer decline of U. lactuca in this shallow, eutrophic embayment.

ARE “GREEN TIDES” HARMFUL ALGAL BLOOMS? TOXIC PROPERTIES OF WATER‐SOLUBLE EXTRACTS FROM TWO BLOOM‐FORMING MACROALGAE, ULVA FENESTRATA AND ULVARIA OBSCURA (ULVOPHYCEAE)
TLDR
It is concluded that extracts from both Ulva fenestrata and Ulvaria obscura have allelopathic properties, which could alter competitive interactions by inhibiting germination or development of algae and invertebrates.
Control of macroalgal blooms at early developmental stages: Pilayella littoralis versus Enteromorpha spp.
TLDR
It is shown that spores and/or germlings may represent critical stages in the life cycles and mass-developments of co-occurring opportunistic macroalgae in the Baltic (Pilayella littoralis and Enteromorpha spp.) and grazers, if present, may play a decisive role in the early life stages of macroalgal mass developments.
