geographical variation in the use of intertidal rocky shores by the lizard microlophus atacamensis in relation to changes in terrestrial productivity along the atacama desert coast.1. the movement of materials and organisms between ecosystems is a common process in nature. 2. in the present study we investigate the hypothesis that the movement of consumers between ecosystems depends not only on the differences in productivity between ecosystems and prey availability, but also on these animals' biological characteristics. 3. to address this hypothesis we investigated the changes in abundance, habitat utilization and diet of the lizard microlophus atacamensis along its geogr ...200818416712
