“…This hypothesis is consistent with that proposed by Perovich et al (2003) to explain the congregation of ovigerous Bythograea thermydron towards the periphery of a vent field. The same hypothesis has also been evoked to account for the apparent paucity of ovigerous female Rimicaris exoculata in the immediate vicinity of black smokers at deep Mid-Atlantic hydrothermal vents (Copley 1998, Ramirez Llodra et al 2000.…”

“…However, recent studies have revealed spatial and temporal variation in the reproductive development of some species at hydrothermal vents (Copley et al 2003, Perovich et al 2003. Similar patterns have yet to be examined at cold seeps, although seasonality has been described in some reproductive features of 1 seep species (Lisin et al 1997).…”

“…Spatial variation in reproductive development is also known for the polychaete Paralvinella palmiformis at Juan de Fuca hydrothermal vents, which reflects the heterogeneity of the vent community (Copley et al 2003). Although zonation in the physiological condition of mussels is known at the Brine Pool cold seep in the Gulf of Mexico (Smith et al 2000), spatial variation in reproduction has yet to be examined in cold seep species.…”

Ecological patterns in deep-sea chemosynthetic environments are often considered to be independent of variations in photosynthetic primary production. This study examined spatial and temporal variation in the reproductive development and population structure of the caridean shrimp Alvinocaris stactophila at the Brine Pool cold seep on the Louisiana Slope. To assess spatial variation, samples were collected by submersible from different locations across the Brine Pool mussel bed in November 2003. The proportion of males in samples declined from the outer to the inner zone of the mussel bed, while the proportion of female shrimp carrying eggs increased. This zonation may have resulted from the congregation of large ovigerous females towards the inner zone, where sulphide flux from underlying sediments may be absent or reduced. To examine temporal variation in reproductive development, oocyte size-frequency distributions were compared between August 1997, March 2002, February 2003, November 2003, and July 2004. All oocytes in early spring samples were small and previtellogenic, while summer samples contained larger vitellogenic oocytes. The largest oocytes were found in large non-ovigerous females from the autumn, whereas ovigerous females from the same season contained the smallest oocytes observed in this study. Embryos in the autumn exhibited no differentiation, in contrast to well-developed embryos from early spring that hatched into zoea larvae. These features indicated seasonal and iteroparous reproduction in A. stactophila, with females carrying embryos from autumn to early spring, possibly timing the release of planktotrophic larvae to exploit a seasonal peak in surface productivity and its export.

“…New surfaces are colonised within a few days by juveniles and non-reproductive individuals. In such patches all individual are nonreproductive, similar to the situation in early succes-sional stages of P. palmiformis (Copley et al 2003). Subsequently, mature individuals that were not reproductive at the time of colonisation progressively enter the reproductive phase of their life-cycle.…”

“…In contrast, P. grasslei (Zal et al 1995) and P. palmiformis (Copley et al 2003) were suggested to reproduce synchronously at the vent scale, responding to periodic variation linked to a tidal regime in environmental factors such as temperature (Chevaldonné et al 1991, Johnson et al 1994). In P. palmiformis, however, spatial variation in reproductive patterns was found at the vent scale, perhaps reflecting a successional mosaic of the vent community, with immature individuals in earlier successional stages (Copley et al 2003). In A. pompejana, the dynamic disturbance/ colonisation process might similarly result in a mosaic of patches harbouring individuals at different reproductive stages (Fig.…”

Animal communities on the walls of deep-sea hydrothermal chimneys are distributed in mosaics of patches that may evolve as local environmental conditions change and biological interactions develop. Alvinella pompejana Desbruyères et Laubier, 1980 is one of the first metazoan colonisers of new surfaces created by mineral precipitation, and therefore may be particularly important in community establishment in active parts of smokers. Here our goal was to investigate the colonisation mechanisms of A. pompejana in new patches and determine whether these mechanisms may influence population structure and reproductive patterns in this species. We deployed a series of TRAC (Titanium Ring for Alvinellid Colonisation) devices at East Pacific Rise (EPR) vent sites to compare the size and stage (i.e. reproductive maturity) distribution of A. pompejana individuals between recently colonised patches (TRACs) and established patches (grabbed by submersible). TRACs deployed for short time periods (11 d to 1 mo) were generally colonised by smaller individuals than those found in background populations or in TRACs deployed for longer time periods (>1 mo). Colonists into new patches were a mix of juveniles and individuals that were sexually mature but non-reproductive (i.e. not producing gametes), whereas background population and older patches harboured a mixture of individuals at different stages including reproductive females. Although some individuals may have recruited on TRACs as larvae, the major colonisation process involved was probably immigration of post-larval stages. In long-term TRAC, reproductive females were not reproductively synchronised. In this dynamic environment, reproduction would be triggered by the disturbance/migration processes, explaining the heterogeneity observed in reproductive patterns.
