Dear colleagues, The next session of the online seminars organised by the ESEB-funded STN network « Integration of Speciation Research » ( [ https://speciation-network.pages.ist.ac.at/ ] ) will take place Tuesday 7th of April at 9am CET. This session falls within the theme "Early Career Researchers in Speciation", with this theme's new format featuring two talks (1 hour total): 1. Charlotte Wright (Postdoc @ Wellcome Sanger Institute, UK) "The Evolution of Chromosome Rearrangements across Butterflies and Moths. 2. Alexander Mackintosh (Postdoc @ U. Uppsala, Sweden): "Evidence for Chromosomal Speciation in Brenthis Butterflies." followed by a 30 min Q&A with Sally Potter (Macquarie U., Australia) about her career path. To attend, please use the following link: https://gu-se.zoom.us/j/63912851182 Talks (but not the Q&A) will be recorded and made available here: https://www.youtube.com/channel/UClEkDdE_5sDw70SQq78DIAA, where you can also find previous seminar recordings. The IOS network aims to promote both scientific and community integration across speciation research. A main objective is to foster diversity and inclusion across the field. We alternate time slots every month to maximise the geographic diversity of attendees. The seminar series and subsequent discussions are open to everyone, from students to established researchers and non-scientists. Please share this email with anyone who may be interested, especially those in countries that are typically underrepresented in scientific discourse. However, please do not post the zoom link on social media. The seminar programme is announced by email, on Bluesky (@speciation-network) and Twitter (@Speciation_net), here on EvolDir, and on the IOS network website. To automatically receive the programme and other news from the IOS network, sign up to the mailing list via the IOS website. We look forward to seeing you there!
