DESCRIPTION:Microorganisms inhabit highly fluctuating natural environments
  and survive in a low-nutrient resource baths. It is now well recognized t
 hat nutrient exchanges among microbes play a vital role in their survival.
  The existence of such exchanges raises fundamental questions about the dy
 namics of these interactions. \nIn this talk\, we will explore experimenta
 lly and theoretically a realization of such interactions in which active b
 acteria dynamically respond to the oxygen produced by immotile green algae
  through photosynthesis. Even in this simplest mixture of active-passive s
 uspensions\, we find a complex dynamics involving nutrient exchanges and e
 nhanced algal diffusivity due to the bacteria.\nTowards the end of the tal
 k\, I will briefly discuss our investigations on collective behaviour in a
 n active fluidic network of filamentous fungi\, which presents another fas
 cinating example of dynamical complexity in living systems.
