| 研究実績の概要 |
This project will develop a spatially-explicit model and use field-based studies to investigate the evolutionary and ecological drivers of different reproductive strategies. It will integrate various selective pressures with the trade-off between colonization and competitive ability to shed light upon which environments select for a single (optimal) or coexisting multiple reproductive strategies, and the diversity of strategies which may evolve under different conditions. Theoretical work will be validated by field work to obtain empirical data using ants, an established model system in the host-lab that exhibits variable strategies in populations throughout Japan.
Dr Planas-Sitja is leading this study under the supervision of Assoc. Prof. Adam Cronin, and in close collaboration with researchers at Sorbonne University in Paris. Dr Planas-Sitja joined the Animal Systematics Laboratory at TMU in November 2018, and has thus had approximately 5 months in which to get settled and make progress on model development. During this time, he has worked effectively and efficiently toward the goals of the project and we are now starting to see the first results of the simulation model. Development of the model is now largely complete, and the next stages of the project are planned for 2019, including running systematically planned simulations and the first field season of the study. The first outputs of the study should also appear later in 2019 in the form of one publication and one or more conference presentations.

理由
Model development progressed swiftly thanks to an early stage of production in Japan followed by a visit to Paris in December 2018 - January 2019 to meet with research collaborators Nicolas Loeuille and Thibaud Monnin to discuss model development. This allowed input from all collaborators to be incorporated during model development. This was followed by intensive testing phase during which various early bugs have been attended to and code optimized. The model code has subsequently been expanded and developed to include various input and output options and data-tracking options for data acquisition. In addition, methods have been explored to run simulations on various external super-computers including those at RIKEN and in Sorbonne in Paris. This groundwork has permitted the model to be largely completed by April 2019, and work will soon commence on running simulations for preparation of the first manuscript.

| 今後の研究の推進方策 |
A trip to Paris is planned during summer 2019 in order to confer with collaborators at Sorbonne University to conduct analyses of the first round of simulation runs and work toward completing the first manuscript, as well as to develop the basis for the second manuscript. This visit will also be used to disseminate the first results of this study, in three different forums: the International Society for the Study of Social Insects meeting in Avignon, France (https://colloque.inra.fr/insectes-sociaux2019/), a public engagement lecture in Banyoles, Spain (http://www.astrobanyoles.org/codi/tardesdeciencia.php), and as part of the Interdisciplinary Seminar Series at the Universite Libre de Bruxelles in Belgium ().
In Japan, the summer of 2019 will be used to obtain the first field-data for this study. Trips will be made to Gifu and/or Hokkaido to collect colonies of ants. These data will be used to test predictions of the model and contribute toward manuscripts using multiple lines of evidence.
