Title: Does phase separation explain spatial patterns in ecosystems?
Event: (ADIW04) Anti-Diffusion in Multiphase and Active Flows
Abstract: Johan van de Koppel & Quan-Xing Liu
Spatial patterns are ubiquitous in many pristine ecosystems, playing an important role in defining the adaptive capacity of ecosystems to changing environmental conditions. The predominant explanation for pattern formation in ecosystems is Alan Turing’s activator-inhibitor system, where local positive feedback improves growth, while long-range negative feedback inhibits growth. Here, I argue that phase separation could provide an alternative class of mechanism for self-organized pattern formation in ecosystems, that builds on the aggregation of a biotic or abiotic species, sediment, or nutrients, and even herbivores. Using a generalized mathematical model, we demonstrate that ecosystems with aggregation-driven patterns have fundamentally different patterns, dynamics and resilience properties than ecosystems with patterns that formed through scale-dependent feedbacks.

    Interesting video, but I have a question: You mention von Neumann in your lecture, and you have studied geophysics at UCLA, and Condensed Matter elsewhere ...do you notice something unusual in Mary Fowler's PREM chart that fascinated von Neumann and might have fractal analogies in CM?? (Which Hamiltonian are you referring to? (The classic of one on the Broom-bridge, or its use in Schrodinger equations?? I think either way, one might already be in a possible 'rabbit-hole')... unless the cranked out results are pragmatically impressive... questions at minute 21 and later are fascinating! ...

    Dr Loos, you co-authored the article "Finite-size scaling at the edge of disorder in a time-delay Vicsek model" with scientists and a PhD student from the University of Leipzig in 2021. Are you aware of the fact that the PhD student incorporated texts from your collaborative article into his PhD thesis in 2022, presenting them as his own independent work? Did you aid him in any way, either by editing or otherwise, in his dissertation? You co-authored another article with the PhD student titled "Delay in motile active matter: the role of perceptionreaction delays". Where can this article be found? I am asking this because of a large-scaled dissertation fraud that has taken place at the University of Leipzig. There are apprehensions that academics from other universities may also be implicated, although it is hoped this is not the case.

    Dr. Holubec is currently under investigation at the University of Leipzig. He is accused of having co-authored dissertations for doctoral students as a ghostwriter. It is remarkable that Holubec is going on tour with excerpts from these works. Didn't we recently see the Donald Duck drawing and the introduction at 02:48 in a similar form in a dissertation by one of his doctoral students? Interesting in any case.
