【 摘 要 】

ABSTRACT: Variation in the distribution of animals across the landscape, within and between habitats, can occur at a variety of scales. At the smallest scale, individuals can either be positioned randomly or can be orientated in regard to variables. Differences in orientation can, for many animals, directly affect their reproductive success and/or survivorship, and these effects may have downstream ecological consequences. Organisms may orientate themselves in a specific way in response to varying environmental conditions or habitat properties; alternatively they may consistently orientate in a specific direction. The present study investigated patterns of orientation during low tide in the intertidal marine limpet
