| Deep-sea hydrothermal vents display extreme and highly variable environmental conditions that are expected to be among the most important factors structuring associated benthic populations and communities. We tested this assumption,focusing Oil the distribution of gastropods, as well as on the demographic population structure and reproductive biology of one dominant gastropod species ill zones characterized by alvinellid polychaetes and vcstimentiferan tubeworms. A total Of 14 biological samples from both types of habitats were collected at three sites oil the East Pacific Rise 13 degrees N vent field in May 2002. At all vents except one, the physico-chemical environment was described in two steps: (1) pH, total sulphide and reduced iron concentrations... |
