About Integrative Organismal Systems (IOS)

IOS supports research aimed at improving our understanding of organisms as integrated units of biological organization.  The Division welcomes projects that employ diverse approaches to research addressing organismal-level questions. 

IOS particularly encourages research that:

  • is integrative and interdisciplinary
  • applies approaches that combine experimentation, computation, and modeling
  • leads to new conceptual and theoretical insights and testable predictions about integrated organismal properties, including the relationship between genotypes and phenotypes
  • integrates data across spatial/temporal/ biological scales
  • leads to transformative methods, tools and resources
  • seeks breakthroughs in the areas of phenotypic plasticity and organismal resilience
