1 International Research Project
International Research Projects are collaborative research projects between CNRS and partner laboratories. They strengthen previously-established collaboration and allow to develop joint research activity, field work, experimentation, and supervising students. Their mandate is 5 years and can be extended once.
The IRP (LIA) “International French Malaysian Natural Products Laboratory”, IFM NATPROLAB, was created on 1 January 2015 for a term of 4-years (2015-2018), and was renewed at the end of 2018, as an International Research Program (IRP) for an additional period of four years (2019-2022). IFM NATPROLAB allowed strengthening a scientific collaboration between Institut de Chimie des Substances Naturelles (ICSN, UPR2301, CNRS) and Phytolab of the Department of Chemistry of the Faculty of Sciences, University Malaya.
1 International Emerging Action
International Emerging Actions are PI-to-PI projects whose purpose is to explore new fields of research and international partnerships through: short-term mobility of scientists, the organisation of working meetings, and the initiation of early-stage joint research works for shared scientific projects. These actions have a duration of two years.
Hybodont sharks represent one of the most successful chondrichthyan lineages of all time. They appeared as early as the Late Devonian and they disappeared at the end of the Cretaceous. On the other hand, the modern-day sharks, or selachimorphs, started to diversify in the Early Jurassic and by the end of the Jurassic, they dominated marine environments. Although the real impact of selachimorph diversification on hybodont evolution is still unclear, there is a neat diversification of hybodonts in freshwater environments during the Early Cretacous, whereas selachimorph sharks remained very rare into such an environment until the disappearance of the hybodonts. This would suggest that hybodonts took refuge in fresh waters during the Cretaceous to escape competition from neoselachian sharks in marine environments.
