This applies to all DynaTrait members from the 1st funding period: there is no intermediate report after the 1st funding period has come to an end, but you have to contribute to the final report. There are three alternatives for contributing to the final report:
1- Scientific anthology consisting of abstracts of the subproject's research results presented at a final colloqium in presence of at least one DFG referree of the Priority Programme after the end of the first funding period (e.g. the Annual Meeting in Oct 2018 would qualify), OR
2- Scientific anthology consisting of abstracts of the subproject's research results presented in a peer-reviewed special issue, OR
3- Specific report from the subproject's PI
As an example of how to do it, see here the final report in form of a special issue in Zoology based on another DFG Priority Programme (SPP 1399) consisting of Open Access articles:
In addition, the coordinator writes an extra report summarizing the results of the entire programme.
The final report is due 2020, but we need to start compiling the info this year from those who are leaving the Priority Programme in 2018!
