Guidance: IOS Full Proposals (due Aug 5)

The Division of Integrative Organismal Systems has composed a series of blog posts with tips for preparing a full proposal for the upcoming August 5, 2016, deadline for the IOS core programs track. It is not intended to be a complete set of guidelines, but rather to highlight common issues and provide useful additional information. Please consult the current Grant Proposal Guide and the current IOS solicitation for complete instructions. As always, if you have questions contact your Program Director. (Post 1:

The Division of Integrative Organismal Systems (IOS) supports research aimed at understanding why organisms are structured the way they are and function as they do. Proposals should focus on organisms as a fundamental unit of biological organization. Principal Investigators (PIs) are encouraged to apply systems approaches that will lead to conceptual and theoretical insights and predictions about emergent organismal properties. Areas of inquiry include, but are not limited to, developmental biology and the evolution of developmental processes, nervous system development, structure, and function, physiological processes, functional morphology, symbioses, interactions of organisms with biotic and abiotic environments, and animal behavior.

Proposals are welcomed in all of the core scientific program areas supported by the Division of Integrative Organismal Systems. Proposals may be submitted to the two tracks described in this solicitation. All investigator-initiated proposals submitted to the Core track of this solicitation must now be invited based on merit review of preliminary proposals. There is a single submission deadline with a limit of 2 preliminary proposals per investigator per year as PI or Co-PI in response to the Core track of this solicitation.  Please see the GPG for definition of roles for PI and Co-PI. There are no limits on the number of proposals you can participate on as collaborator. These PI/Co-PI limits do not apply to full proposals submitted to the EDGE track of this solicitation, which has no PI or Co-PI limits on number of proposals submitted. The PI/Co-PI limits apply only to the preliminary proposals submitted to the Core track of this solicitation and do not pertain to proposals submitted in response to other NSF solicitations.

Unsolicited full research proposals are no longer accepted into the IOS Core Programs. Full proposals submitted on a single deadline to the EDGE track of this solicitation do not require prior submission of a preliminary proposal. A Letter of Intent is required before submission of a full proposal to the EDGE track of this solicitation.
