【 摘 要 】

ABSTRACT: This study quantifies patterns in settlement and colonization of hydrothermal vent invertebrates and explores relationships with the biotic and abiotic factors that may influence these patterns. Colonization was measured between 2001 and 2003 in 2 segments of the Juan de Fuca Ridge, by deploying sets of basalt blocks at vents with different flow characteristics, over different spatial (cm to 100 km) and temporal (1 to 2 yr) scales. Spatial variation in colonization was greater between vents within a segment (m to km scale) than between segments, which we suggest reflects a species-specific response to varying environmental conditions at a particular vent. For gastropods, gregarious settlement enhanced colonization, while post-settlement mortality influenced colonization patterns of polychaetes. In 2003, we characterized the spatial variability in environmental conditions among 3 vent sites, through discrete
