Abstract. The phaeophyte alga Desmarestiamunda (Order Desmarestiales) concentrates sulfuric acid (H2SO4) in cell vacuoles. The primary function of the accumulated acid in the alga's life history is unknown. To investigate if sulfuric acid works as a chemical defense, grazing by the sea urchin herbivore Strongylocentrotusdroebachiensis on D.munda was compared to grazing on four common non-acidic phaeophyte algae (Alariamarginata, Laminariasaccharina, Costariacostata, and Nereocystisluetkeana) in…

The substances contained in the aqueous–ethanol and aqueous extracts from freshly collected and destroyed brown algae Saccharina cichorioides in their second vegetation season and from excrement of
Chemical and physical defenses against predators in Cystodytes (Ascidiacea)
TLDR
Results and other studies on sponges and gorgonians suggest that secondary metabolite composition, calcareous spicules and tunic acidity may act as redundant defense mechanisms against predation in this genus.
Multidisciplinary Studies of the Genus "Cystodytes" (Ascidiacea): From Molecules to Species
TLDR
Both the reproductive and growth periods, although partially overlapping, showed significant temporal lags, reinforcing previous genetic and chemical results indicating that these morphs are reproductively isolated and represent distinct species.
Chapter 18 Ecology of Strongylocentrotus droebachiensis
TLDR
It is the most widely distributed member of the Strongylocentrotus droebachiensis family and plays a key ecological role in determining the distribution and abundance of benthic macroalgae, particularly kelps.
Do sulphuric acid and the brown alga Desmarestia viridis support community structure in Arctic kelp patches by altering grazing impact, distribution patterns, and behaviour of sea urchins?
TLDR
Results improve the understanding of how isolated kelp beds can persist over a wide range of environmental conditions, like wave-sheltered sites, and suggest that changes in community structure may be in part attributable to altered trophic interactions.
Ligulate Desmarestia (Desmarestiales, Phaeophyceae) revisited: D. japonica sp. nov. and D. dudresnayi differ from D. ligulata
TLDR
The phylogeny of ligulate and sulfuric‐acid containing species of Desmarestia, occurring worldwide from polar to temperate regions, was revised using a multigenic and polyphasic approach, reducing a total of 16 taxa to four different species.
Algal colonization in urchin barrens: defense by association during recruitment of the brown alga Agarum cribrosum
We investigated the process whereby juveniles of the kelp Agarum cribrosum escape grazing by the green sea urchin, Strongylocentrotus droebachiensis, on urchin barrens in the rocky subtidal zone in
Lacuna vincta (Mollusca, Neotaenioglossa) herbivory on juvenile and adult Nereocystis luetkeana (Heterokontophyta, Laminariales)
TLDR
The effects of grazing by the littorinid gastropod, Lacuna vincta, on different age classes of the bull kelp, Nereocystis luetkeana, are investigated and it is concluded that at a local scale, L.vincta can be an important structuring factor in Nerecystis populations due to its high density and grazing ability.
Organismal defenses versus environmentally mediated protection from herbivores: Unraveling the puzzling case of Desmarestia viridis (Phaeophyta)
TLDR
It is concluded that the chemical makeup of D. viridis alone is neither necessary nor sufficient to limit contacts by the urchins and that wave action is a major factor explaining the survival of D.'s viridis on urchin barrens, because waves limit the movements of the urches towards the alga.
Distribution and morphology of defensive acid-secreting glands in Nudipleura (Gastropoda: Heterobranchia), with an emphasis on Pleurobranchomorpha
TLDR
This work investigates and compares defensive acid-secreting cell types of various genera within the heterobranch taxon Pleurobranchomorpha by analysing the sizes and distribution of the secretory epithelial cells and subepithelial glands of the epidermis, and investigates the median buccal gland (MBG).

ACCUMULATION OF SULFURIC ACID IN DICTYOTALES (PHAEOPHYCEAE): TAXONOMIC DISTRIBUTION AND ION CHROMATOGRAPHY OF CELL EXTRACTS
TLDR
Four species in the order Dictyotales were found to be highly acidic as in some species of the order Desmarestiales (Phaeophyceae), and Estimated cellular proton concentrations calculated from the pH data roughly agreed with those calculated from differences between the sum of cations and anions and that of anions.
Polyphenols in brown algaeFucus vesiculosus andAscophyllum nodosum: Chemical defenses against the marine herbivorous snail,Littorina littorea
TLDR
It is concluded that polyphenols in F. vesiculosus and A. nodosum are functionally similar to terrestrial plant polyphenol (tannins) in providing chemical defenses against herbivores.
Preferential Feeding: An Optimization Strategy in Sea Urchins
TLDR
Preference experiments showed that substance(s) readily sloughed from the fronds of Nereocystis attract urchin whereas substances from A. fimbriatum repel or are not detected by urchins.
Factors influencing food choice by the seaweed-eating marine snail Norrisianorrisi (Trochidae)
TLDR
The data suggest that the preference of N. norrisi for kelps over other potentially edible and palatable seaweeds may not be related to nutritional content, but instead may have evolved in response to factors such as availability, habitat provision, or refuge from predation.
FEEDING PREFERENCES OF TEGULA FUNEBRALIS AND CHEMICAL DEFENSES OF MARINE BROWN ALGAE
TLDR
Feeding preferences of Tegula funebralis for brown algae are primarily due to avoidance of algal defenses; positive aspects of food quality (such as attractants or nutritional content) probably play a lesser role in determining preference.
Depth-dependent reproductive output of the green sea urchin, Strongylocentrotus droebachiensis (O.F. Müller), in relation to the nature and availability of food
TLDR
Gonad weight and reproductive output of urchins from habitats poor in food can be increased by providing preferred foods.
SULFURIC ACID IN DESMARESTIA
TLDR
The simplest interpretation of these data is that the acid is localized within the vacuoles of Desmarestia cells.

TLDR
There is good congruence between phylogenetic tree topology and temperature impints in relation to biogeographic distribution, supporting the theory that temperature tolerance is a conservative trait.

Foods and predators of the green sea urchin Strongylocentrotus droebachiensis in Newfoundland waters
TLDR
Gut analyses of the green sea urchin Strongylocentrotus droebachiensis demonstrated that perennial phaeophytes, mostly fucoids and Alaria esculenta, were predominant in the diet, causing the dearth of non-coralline sublittoral algae in Newfoundland waters.
