DESCRIPTION:Carey Nadell\, Max Planck Institute for Terrestrial Microbiolo
 gy\, Marburg\, Germany\nGiven the opportunity\, many bacterial species col
 onize surfaces and produce intricate multicellular communities\, termed bi
 ofilms. These cell groups are embedded in a secreted polymer matrix that c
 onfers nutrient-scavenging versatility and resistance to external threats.
  Biofilm growth is a central feature of microbial natural history and bact
 eria-human interactions\, but we are still in the early stages of discover
 ing ecological principles of biofilm assembly. I use concepts and techniqu
 es from ecology\, evolutionary biology\, and molecular genetics to underst
 and how and why biofilms obtain their structure and composition. Here I wi
 ll relate several projects linking the secreted matrix to cooperation\, co
 mpetition\, and succession in populations of bacterial pathogens. I will a
 lso discuss a new system for visualizing the spatial spread of bacterial v
 iruses through biofilms. This framework promises novel insight into bacter
 ia-bacteriophage coevolution and the development of new microbial manipula
 tion strategies.\n
