摘要: Global seascapes are increasingly modified to support high levels of human activity in the coastal zone. Modifications include addition defense structures and boating infrastructure, such as seawalls marinas that replace natural habitats. Artificial different macrofaunal communities those found on rocky shores; however, little is known about differences microbial community structure or function urban seascapes. Understanding how artificial constructions marine environments influence important these assemblages contribute many basic ecological processes. In this study, bacterial intertidal biofilms were compared between (seawalls) habitats (rocky shores) within Sydney Harbour. Plots cleared each type habitat at eight locations. After 3 weeks newly formed biofilm was sampled 16S rRNA gene sequenced using Illumina Miseq platform. To account for orientation substrate material shores might have influenced our survey, we also deployed recruitment blocks next all locations then their communities. Intertidal from plots differed shores, but when material, age kept constant (with blocks) similar composition among This suggests changes not related environmental locations, may be other intrinsic factors differ orientation, complexity, predation. one first comparisons surfaces illustrates substantial with potential consequences macrofauna.
