Don't miss Tom Clegg's (@cleggtom.bsky.social) poster today at EcoNet 2025 with the title "Cross-feeding networks create tipping points in microbiome diversity" where he tries to answer the question how biodiversity of microbiomes emerges from interactions between populations.

If you’re attending EcoNet 2025, don’t miss Jordan Gault’s (@jagault.bsky.social) poster presentation: “Dissimilarity analysis based on diffusion maps.” His work highlights how diffusion maps, a manifold learning approach, provide powerful new tools to track community change across space and time.

If you're at CCS 2025 this week: Tues, Sep 2nd, 12:15 pm, Room 15, Melanie (@mhab.bsky.social) will present her work on functional motifs in foodwebs and networks. Same day, Room 14, Tim (@timmauch.bsky.social) talks about diffusion-driven pattern formation in an opinion dynamical network model.

Paper alert! See the new pre-print up on arXiv by Tim Mauch (@timmauch.bsky.social) and Thilo Gross (@thilogross.bsky.social) on opinion formation: arxiv.org/abs/2508.15377 The paper discusses the very nice results of Tim's master thesis, so let's get into the details, shall we? 1/5

Luckily, we can start this week where we left off the last last —with another successfully completed PhD! Laura Barth defended her work on phase transitions in robust networks. What a fascinating application of generating functions. Congrats, Laura! We are all incredibly proud of you!

What's the best way to top off a great week? For us, it was celebrating Pedro Carrasco's successful PhD defense last Thursday. His research explored how diffusion maps can aid in computing functional biodiversity from long-term time series. Congratulations, Pedro! We are all incredibly proud of you!
