Theses and Dissertations
Biofilms dominated by bacteria and diatoms universally colonize submerged surfaces and mediate larval recruitment in benthic marine systems. The ability for macrofoulers to be transported by vessels and become globally established is likely affected by cues from the biofilm organisms they encounter. This study investigates how macrofoulers respond to biofilms shaped by local geography, transport processes and relocation. Biofilm assemblages in neighboring ports were largely unique to the site at which they were developed. Bacteria were primary drivers of variations among sites, and overall bacterial richness was an order of magnitude higher than has been reported for other marine environments. …
