  • Imposex in Endemic Volutid from Northeast Brazil (Mollusca: Gastropoda)

Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These compounds are used as biocide agents in antifouling paints to prevent the incrustations on boats. Five gastropod species are known to present imposex in Brazil: Stramonita haemastoma, Stramonita rustica, Leucozonia nassa, Cymathium parthenopeum and Olivancillaria vesica. This paper reports the first record of imposex observed in the endemic gastropod Voluta ebraea from Pacheco Beach, Northeast Brazil. Animals presenting imposex had regular female reproductive organs (capsule gland, oviduct and sperm-ingesting gland) and an abnormal penis. As imposex occurs in mollusks exposed to organotin compounds typically found at harbors, marinas, shipyards and areas with high shipping activities, probably contamination of Pacheco Beach is a consequence of a shipyard activity located in the nearest areas.

  • Identification Assisted by Molecular Markers of Larval Parasites in Two
    Polar Biology https://doi.org/10.1007/s00300-019-02511-6 ORIGINAL PAPER Identifcation assisted by molecular markers of larval parasites in two limpet species (Patellogastropoda: Nacella) inhabiting Antarctic and Magellan coastal systems K. Flores1 · Z. López2,3 · D. Levicoy1 · C. P. Muñoz‑Ramírez4,5 · C. González‑Wevar6 · M. E. Oliva7,8 · L. Cárdenas1 Received: 10 August 2018 / Revised: 30 April 2019 / Accepted: 8 May 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract In the Southern Ocean, many parasites of vertebrates (mainly helminth groups) have been recognized as endemic species, but parasites of marine invertebrates remain almost unknown. It is reasonable to assume that digenean larvae will parasitize gastropods, bivalves, amphipods, and annelids, the usual frst and second intermediate hosts for those parasites. Here, using an identifcation assisted by molecular markers, we report the Digenea species parasitizing the most abundant limpet species inhabiting ice-free rocky intertidal and subtidal zones of the Southern Ocean, viz. Nacella concinna from the Antarctic and Nacella deaurata from the Magellan region. The limpets harbored larval Digenea (two metacercariae and one sporocyst). Phylogenetic analysis based on the multilocus tree supported the hypothesis that N. concinna is parasitized by a species of Gymnophallidae, whereas the limpet N. deaurata is parasitized by Gymnophalloides nacellae and a species of Renicolidae. In addition, diferences in prevalence and intensity were also recorded between the two compared host species and also from other congeneric species. This new knowledge in parasite species in marine invertebrates from the Southern Ocean reveals the presence of a particular parasite fauna and confrms the utility of molecular tools to identify biodiversity still scarcely known.
