Rapid recovery of native habitat-builders following physical disturbance on pier pilings offsets colonization of cryptogenic and non-indigenous species in a Chilean port

摘要: Abstract Examining the effects of disturbances within marine urban communities can shed light on their assembly rules and invasion processes. The physical disturbance, through removal dominant native habitat-builders, were investigated in recolonization disturbed patches colonization plates pier pilings, a Chilean port. On disturbance substantially affected community structure after 3 months, although it slowly converged across treatments 10 months. plates, cryptogenic non-indigenous species richness increased with severity, which was not observed natives. Opportunistic taxa took advantage colonizing at an early successional stage, illustrating competition-colonization trade-off, indirect might be play (e.g. trophic competition or selective predation). Recovery habitat-builders then occurred expense taxa. Whether natives could continue winning against increasing propagule pressures habitats deserves further attention. interactions between biological invasions herein experimentally shown situ contribute to our understanding multiple changes imposed by urbanization growing transport network.
