“…Based on the arrangement of the imposed male organs in imposex-affected females, Nassarius reticulatus has been classified among other gastropods in which imposex does not lead to female sterility (Gibbs et al 1997). External inspection of the female genitalia, employed in this study, has failed to reveal what happens to the VD once it reaches the ventral channel (i.e.…”

“…Imposex is a widespread phenomenon caused by tributyltin (TBT), a compound used in antifouling paint (Gibbs et al 1988(Gibbs et al , 1991(Gibbs et al , 1997, and has been reported in several coastal gastropods, particularly in species associated with harbour waters (Santos et al 2000, Bech 2002, Bigatti et al 2009). The Mar del Plata harbour is the most important fishing harbour in Argentina, with a coastal and offshore fleet of more than 300 vessels (Errazti & Bertolotti 1998).…”

Adelomelon beckii (Broderip, 1836) (Neogastropoda: Volutidae) is endemic to the western south Atlantic coast. It inhabits sandy bottoms in waters between 40 and 70 m deep and is one of the largest top benthic predators found in Mar del Plata, Argentina. The present study describes gametogenesis and the reproductive cycle of this species. Oocytes developed in close association with follicle cells, which appear to play a role in yolk synthesis and oocyte resorption, providing the key functions of phagocytosis and intracellular digestion of degenerating oocytes. Spermatogenesis resembles that reported for other volutids. The reproductive cycle of A. beckii in Mar del Plata was studied over a period of 2 yr (September 2004 to August 2006). Gametic emission in males continued throughout the year while females showed 2 spawning periods: one during spring (September-November) and another during autumn (March-April). In females, this semi-annual pattern appears to be related to the seasonal variation in seawater temperature, coinciding with observations made in other volutes. In males, there was no relationship to variation in seawater temperature, an unusual pattern for a species from a temperate region. Imposex was described for the first time in this species. These data constitute baseline information for establishing appropriate and biologically based management and conservation strategies for this overexploited gastropod species.KEY WORDS: Adelomelon beckii · Gametogenesis · Reproductive cycle · Volutidae · ImposexResale or republication not permitted without written consent of the publisher

Males of Nucella lapillus (L.), an intertidal gastropod, can suffer from a curious genetic disorder that causes underdevelopment of the reproductive tract ['Dumpton Syndrome' [DS]). Its extreme form leads to a lack of a penis ('aphally') and an incompletely developed vas deferens (VD). DS-affected females are also recognisable by a lesser degree of masculinisation ('imposex') when exposed to tributyltin (TBT) pollution, i.e. penis development may be lacking (female 'aphally') and VD formation may be iveak. Based on the results of an extensive survey [at 56 stations) around GaLicia (NW Spain) from 1996 to 1998, it is now known that imposex is widespread and the variations shown in its development indicate that DS also occurs widely. A modified version of the Vas Deferens Sequence (VDS) schemes currently devoted to assess the intensity of masculinization of female N. lapillus is proposed. It attempts to accommodate the vanants in imposex development observed in a DS-affected population whilst remaining both simple and comparable with previously applied schemes. The proposed VDS classification solely employs VD development as a rankmg criterion so as to attain a consistent scoring of both aphallic and penis-bearing females. Irnportantly. the evidence indicates aphally need not preclude a female from being sterilized. Both males and females afflicted by DS were scattered throughout the Gaiician region, although aphaliic females were present at many sites at which DS males went unrecorded. Also, female aphally was commonly more frequent than male aphally on a per site basis. DS-affected males were very unconunon, never exceeding -20% and more frequently constituted ~10%. In contrast, aphallic females were common, reaching frequencies of 20 to 50% at some sites, although overall it also must be considered a low-frequency phenomenon. Imposex levels. overwhelmingly dominated by VDS Stage 4 , showed that TBT pollution is widespread throughout the region. However. a high degree of inter-individual variability was found at many locations. At those sites, females showing no signs of irnposex or only an early stage (i.e. VDS Stages 0 to 2) were found thriving alongside heavily afflicted individuals (VDS Stages 4 to 6). The significant association between this variability in the effects of imposex and the presence of DS strongly reinforces the interpretation of DS as a genetic disorder which lessens the effects of TBT The consequences those TBT-resistant specimens might have for the impact of TBT on the population level are discussed as well as the impact their presence might pose for the assessment of TBT pollution and its effects based on irnposex indices currently in use.
