Long-term shifts in the north western Mediterranean coastal seascape: The habitat-forming seaweed Codium vermilara
2018, Marine Pollution BulletinCitation Excerpt :Similarly, acidification does not seem to be related with the changes found, and moreover, this species is not calcified. At smaller scales, natural disturbances such as overgrazing due to sea urchins, opisthobranchs and small fishes (Frantzis and Grémare, 1992; Gavagnin et al., 1996; Bariche, 2006; Hereu et al., 2008; Cutignano et al., 2009) have been described for C. vermilara. However, there is no species known to feed exclusively on C. vermilara, and the effect of herbivores upon C. vermilara populations has never been quantified.
Is phototridachiahydropyrone a true natural product?
2015, Revista Brasileira de FarmacognosiaCitation Excerpt :This is in agreement with the suggestion that these metabolites are synthesized de novo rather than simply deriving from dietary sources (Ireland and Scheuer, 1979; Ireland and Faulkner, 1981; Gavagnin et al., 1994b; Díaz-Marrero et al., 2008). The biosynthesis of polypropionates in plakobranchidean sacoglossans has been rigorously proven in some species by in vivo feeding experiments (Ireland and Scheuer, 1979; Gavagnin et al., 1994a; Cutignano et al., 2009). Four distinct structural architectures can be recognized in plakobranchidean polypropionates: 1,3-cyclohexadiene derivatives, e.g. 9,10-deoxytridachione (1) (Ireland and Faulkner, 1981); bicyclo[3.1.0]hexanes, e.g. photodeoxytridachione (2) (Ireland and Scheuer, 1979); bicyclo[4.2.0] hexanes, e.g. ocellapyrone A (3) (Manzo et al., 2005; Miller and Trauner, 2005); and fused pyrone-containing bicyclic ring derivatives, e.g. tridachiahydropyrone (4) (Gavagnin et al., 1996; Jeffery et al., 2005; Sharma et al., 2008).
First chemical study of the sacoglossan Elysia patagonica: Isolation of a γ-pyrone propionate hydroperoxide
2013, Biochemical Systematics and EcologyCitation Excerpt :The occurrence in E. patagonica of a molecule belonging to deoxytridachione/photodeoxytridachione structural family is in agreement with the chemical scenario depicted for elysioidean sacoglossan opisthobranchs (Cimino et al., 1999; Cimino and Ghiselin, 1998, 2009). These γ-pyrone polypropionates could be considered chemical markers for a selected group of Elysia sacoglossans including E. crispata (Ireland et al., 1979; Ireland and Faulkner, 1981; Ksebati and Schmitz, 1985), Elysia diomedea (Ireland et al., 1978; Ireland and Faulkner, 1981; Cueto et al., 2005; Díaz-Marrero et al., 2008), Elysia timida (Gavagnin et al., 1994b), E. chlorotica (Dawe and Wright, 1986), Elysia viridis (Gavagnin et al., 1994a; Cutignano et al., 2009) and E. patagonica (this paper). Interestingly, the sacoglossan P. ocellatus is also featured by the same chemistry (Ireland and Scheuer, 1979; Fu et al., 2000; Manzo et al., 2005).

2013, Journal of Experimental Marine Biology and EcologyA bacterial source for mollusk pyrone polyketides
2013, Chemistry and BiologyCitation Excerpt :Our system is challenging for ecology studies in that the snails live in relatively deep water (−70 m) and do not survive well in aquaria. However, related molecules from shell-less mollusks have been experimentally determined to serve roles such as defense, regeneration, and communication (Gavagnin et al., 1994; Davies-Coleman and Garson, 1998; Ireland and Scheuer, 1979; Di Marzo et al., 1991, 1993; Sleeper and Fenical, 1977; Manker et al., 1988; Darias et al., 2006). Further study is required to determine whether the pyrones play these or other roles within cone snail mucus.
