Abstract Understanding the response of microbial communities to different ecological regimes in eutrophic lakes and underlying assembly mechanisms is great significance for revealing biodiversity maintenance lake ecosystems under alternative stable states. However, our current understanding sediment emergent macrophytes regime shifts remains limited. Here, we demonstrated, first time, asynchronous variations littoral bacterial fungal communities, regarding diversities, mechanisms, inter‐kingdom interactions across three regional regimes: macrophyte‐dominated, transitional, phytoplankton‐dominated. We found alpha diversities showed opposite trends, as transitional had highest but lowest diversities. Stochastic processes, dominated by dispersal limitation, determined community assembly, whereas deterministic especially variable selection, shaped community. The number species–environment proportion intra‐kingdom were observed co‐occurrence network regime; however, this (bacteria–fungi) among regimes. Furthermore, macrophyte‐dominated was have most complex structure maintain stability. rhizosphere Phragmites australis enhanced communities. These findings provide a preliminary perspective hysteresis environmental stress at level emphasize importance distinguishing ecologically distinct taxa future studies focused on

We propose using the ordinal pattern transition (OPT) entropy measured at sentinel central nodes as a potential predictor of explosive transitions to synchronization in networks various dynamical systems with increasing complexity. Our results demonstrate that OPT entropic measure surpasses traditional early warning signal (EWS) measures and could be valuable tools available for predicting critical transitions. In particular, we investigate diffusively coupled phase oscillators chaotic Rössler systems. As maps, consider neural network Chialvo maps star scale-free configurations. Furthermore, apply this time series data obtained from electronic circuits operating regime.

The behavior of nonlinear systems near critical transitions has significant implications for stability, transients, and resilience in complex systems. Transient times, τ, become extremely long phase (or bifurcations) a phenomenon known as slowing down, are observed electronic circuits, circuit quantum electrodynamics, ecosystems, gene regulatory networks. Critical down typically follows universal laws the form τ|μμc|β, with μ being control parameter μc its value. For instance, β=1/2 close to saddle-node bifurcations. Despite intensive research on phenomena single bifurcations, both local global, transients when several bifurcations each other remains unknown. Here, we investigate two merging into transcritical one. Using gene-regulatory model normal exhibiting mushroom bifurcation diagram show, analytically numerically, synergistic, i.e., nonadditive, lengthening due coupled ghost effects down. We also show that intrinsic extrinsic noise play opposite roles transition, allowing us timing transition without compromising precision timing. This establishes molecular strategies generate genetic timers much larger than typical timescales reactions involved. Published by American Physical Society 2025
