“…Generally brown algae were found to produce little or no DMSP depending on the detection limit in the respective studies (see e.g. Reed, 1983;Karsten et al, 1990;Bischoff et al, 1994). In accordance with these studies, D. dichotoma used in our experiment released low concentrations of DMS after wounding (up to 50 mg DMS g -1 ; Table 1).…”

Abstract. The chemical defence potential against herbivores of certain Dictyotalean brown algae increases after tissue disruption. This wound activated defence has been explored in bioassays, but the metabolic pathways behind it are unknown. Here we describe a metabolic profiling approach to identify the activated defence metabolites. Before and after tissue damage of Dictyota dichotoma modified diterpenes, non-volatile medium polar metabolites as well as volatile compounds were profiled. While comparison of extracted intact and mechanically wounded algae revealed no significant differences in structure and distribution of semi-volatile and reversed phase LC/MS detectable metabolites, a strong release of gaseous volatiles was observed. Solid phase micro extraction (SPME) and GC/MS were used for identification and quantification of these biogenic gases. This showed that D. dichotoma released elevated amounts of trimethylamine (TMA) and dimethylsulphide (DMS) after mechanical tissue damage. To study the ecological significance of compounds released post injury and of the biosynthetically connected non-volatile acrylate, choice assays were performed with the amphipod Amphithoe longimana. Behavioural assays on artificial diets did not reveal any repellent role for the single isolated metabolites. In strong contrast, a mixture of TMA, DMS and acrylate significantly reduced the association of the herbivores with the treated food pellets. This shows that mixtures of these biogenic gases and acrylate are recognized by the herbivores and influence food selection.

“…To examine the distribution and abundance of DMSP across geographic regions and taxa of marine macroalgae, we compiled data from several surveys of DMSP concentrations that were conducted throughout the world in which DMSP concentrations were reported on a dry mass (DM) basis (Bischoff et al, 1994;Erickson et al, 2006;Karsten et al, 1994;Lyons et al, unpublished data;Van Alstyne, unpublished data;Van Alstyne et al, 2001). The data were sorted into 8 large-scale geographic regions based on delineations of Cox and Moore (1993) and Briggs (1974) to look at the abundance of DMSP on a global scale.…”

“…DMSP concentrations in the Ulvales were more uniformly high with concentrations in 14 of the 15 species being at least 48 mmol g -1 DM. The only exception was the tropical chlorophyte Ulva conglobata (0.3 mmol g -1 DM; Bischoff et al, 1994).…”

The production of dimethylsulfoniopropionate (DMSP) and its cleavage products are well studied in phytoplankton. However, less is known about their sources, distributions, functions, and impacts in other marine organisms. We examined the distribution of DMSP in benthic macroalgae and macroinvertebrates geographically and taxonomically. In macroalgae, concentrations significantly increased from the tropics to the poles in the northern, but not the southern, hemisphere. The increase in the northern hemisphere was due to an increase in concentrations with latitude in the Chlorophyta. This pattern was generated by a relatively high proportion of species in the order Ulvales (median [DMSP]: 145 mmol g -1 dry mass (DM)) at higher latitudes, and a high proportion of species in the orders Caulerpales and Siphonocladales (median [DMSP]: below detection level for both orders) in the tropics. Low DMSP concentrations (< 10 mmol g -1 DM) were reported from all red and brown macroalgae, except Polysiphonia and Halopytis. In macroalgae, some of the reported functions of DMSP and its cleavage products included acting as a compatible solute, an antiherbivore defense, a reactive oxygen scavenger, and a cryoprotectant. Among macroinvertebrates, DMSP occurred in higher concentrations in cnidarians than in sponges and molluscs. Concentrations in animals harboring endosymbiotic algae were 6.5 times higher than animals without symbionts. This and direct measurements of DMSP from isolated symbionts suggest that endosymbionts are a major source of DMSP for some macroinvertebrates. Diet may be a source of DMSP in animals that lack endosymbionts. The functions and impacts of DMSP in invertebrates are not well known.

“…Red and brown algae contained almost the same very low concentrations of DMSP, whereas green algae showed up to 1000 -fold higher values. These distributions are typical and reported for a wide range of polar and tropical macroalgae [compare Karsten et al, 1994;Bischoff et al, 1994]. Thus, a formation of methyl halides by DMSP seems unlikely.…”
