DESCRIPTION:Relativity Trumps Absolutism: P pools in microbes and their eff
 ects on stoichiometry\n\nDr. James Cotner\, University of Minnesota\n\nAbs
 tract\n\nA key component of the Growth Rate Hypothesis is that the element
 al composition of cells is coupled to the rate at which biomass is turning
  over. One of the central elements to this hypothesis is phosphorus (P)\, 
 which is primarily found in cells as nucleic acids (RNA and DNA) which are
  P-rich. Therefore\, faster growing organisms should have more P in their 
 biomass than slower growing ones\, right? Well\, not so fast\, because bio
 mass stoichiometry is really all about the relative contributions of diffe
 rent biomass components. Although organisms grow faster at higher temperat
 ures\, their relative growth rate may not increase or could actually decre
 ase as the temperature rises and this means that the proportion of biomass
  focused on growth (i.e.\, nucleic acids) may decrease as well. Our recent
  work has demonstrated that there can be clear effects of relative growth 
 rates on the biomass composition of heterotrophic bacteria but those effec
 ts differ to a great extent depending on the availability of limiting and 
 non-limiting nutrients\, which specific nutrient is limiting\, and the rel
 ative growth rate. We will explore the implications of relative growth rat
 e for stoichiometric homeostasis and internal pools of phosphorus in proka
 ryotes. \n\nPart of the 2016 Earth Planetary and Space Sciences Institute 
 (EPSSI) Seminar Series\n\nAnnual seminar series on topics related to Earth
  Planetary and Space Sciences and course UN 4000 REMOTE SENSING.
