Abstract:

Rocky shore communities are often influenced by near-shore coastal upwelling. For macrofauna in algal turf, these effects may be caused directly by well-studied bottom-up mechanisms or indirectly via changes in habitat structure provided by algal turf associated high nutrient loads. Here, we investigated possible interactions between upwelling and habitat structure by sampling diverse faunal assemblages in coralline algal turf on seven rocky intertidal shores in northern Chile, ranging from El Cobre [23 17#1$S, 7031#40$W] to La Loberý´a [23 03#40$S, 7033#14$W]. Some of these shores were located adjacent to strong upwelling centers, while others were in areas rarely affected. On each shore, we sampled four (2!2 m) sites separated by 1550 m. In each site, we collected three replicate cores (80 mm in diameter) from which we measured macrofauna greater than 850 mm, biomass of sediment and epiphytes, frond density and average frond length.
