THE SCIENCE Contributed paper sessions: The World Congress of Malacology is an opportunity for malacologists from throughout the world to get together to discuss the animals on which they work. Accordingly, contributed papers and posters on all aspects of malacology are welcome. There are several major symposia: SEXUAL SELECTION IN MOLLUSCS Traits that evolve through selection during the process of mating are said to be sexually selected. Famously, Darwin claimed that sexual selection could not occur in molluscs, because of their hermaphroditism and imperfect senses, but in this he was clearly wrong. In fact, sexual selection is particularly strong in molluscs owing to the prevalence of sperm competition. Some sexually selected molluscan traits that have been documented by recent studies include extreme variations in reproductive anatomies, complex mating systems, variable mating strategies, mate choices, sexual signaling, bizarre courtship behaviours, and post-copulatory manipulations. Because such traits are closely linked to reproductive success, they tend to evolve rapidly, with sometimes unexpected results such as the lovedart. Also, given that the specific reproductive interests of the two sexes are usually different, and may even be in conflict, male and female traits do not necessarily evolve symmetrically. Some recent evidence points to the occurrence of antagonistic co-evolution between male and female traits within hermaphroditic molluscs. In this symposium we aim at an overview of research on sexual selection in molluscs, with the purpose of stimulating and guiding further research on this topic. Contact: Dr. Ronald Chase, Dept. Biology, McGill University, 1205 Ave. Docteur Penfield, Montreal, Quebec, H3A 1B1, Canada; Email: ronald.chase@mcgill.ca; Dr. Joris Koene, Dept.

The global discovery, description and naming of new mollusc species continues at a steady pace. Undersampled regions or habitats, understudied families, as well as old faunas being revisited with new characters, all contribute new species to the global inventory, as they have in the past. However, the global context of molluscan exploration is changing with, e.g., the Convention on Biological Diversity, the Barcoding of Life or the Global Biodiversity Information Facility directly or indirectly affecting the way we collect, analyze and archive specimens and information related to them. How are new explorations changing our perception of the magnitude of regional or global faunas? Where are the frontiers? How is the molecular revolution impacting day-to-day on alpha taxonomy? What are the bottlenecks to describing and naming new mollusc species? What problems and solutions do we share with other taxonomists, and what makes malacologists different? What is / what should be the place of malacological journals in this endeavour? These will be the core questions dealt with by this symposium. XIV
