Seasonal and spatial variability in the abundance of juvenile (&lt; 2.0cm shell length) and adult (&gt; 2.0cm) Drupella cornus along the Ningaloo Reef, Western Australia, were documented during 1990/1991. Numbers of D. cornus were found to vary
significantly between the different sites and reef habitats sampled, with the highest numbers recorded at a backreef edge site at the southern end of the reef. There was no evidence that the densities of D. cornus varied seasonally,
although size-frequency distributions suggest that there may have been a recruitment peak in January/February 1991 following a major spawning event in November/December 1990. Drupella eornus were found predominantly on Acropora species with a caespitose/corymbose growth form; however the abundance of these corals at different sites did not explain the observed distribution patterns of the gastropod. Drupella cornus recruits (&lt; 1.0cm shell length) frequently occurred on corals which were also occupied by larger conspecifics, suggesting that either larval settlement or post-settlement survival were increased in the presence of adult D. cornus.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
