DOI: 10.1002/mma.5394
Abstract: We study the maximum mean discrepancy (MMD) in the context of critical transitions modelled by fast-slow stochastic dynamical systems. We establish a new link between the dynamical theory of critical transitions with the statistical aspects… read more here.

DOI: 10.1007/s10021-021-00610-2
Abstract: Intertidal ecosystems are important because of their function as coastal protection and ecological value. Sea level rise may lead to submergence of salt marshes worldwide. Salt marshes can exhibit critical transitions if the rate of… read more here.

DOI: 10.1016/j.quascirev.2019.01.009
Abstract: Abstract Many ecosystems have abruptly changed in the past and may again in the future, yet prediction and inference of mechanisms causing abrupt changes remains challenging. Critical transitions are one such mechanism, occurring when systems… read more here.

From 2D to 3D in fluid turbulence: unexpected critical transitions
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Fluid Mechanics"
DOI: 10.1017/jfm.2017.507
Abstract: How do the laws of physics change with changes in spatial dimension? Maybe not at all in some cases, but in important cases, the changes are dramatic. Fluid turbulence – the fluctuating, intermittent and many-degree-of-freedom… read more here.

DOI: 10.1038/s41598-019-38961-5
Abstract: Many ecological systems are subject critical transitions, which are abrupt changes to contrasting states triggered by small changes in some key component of the system. Temporal early warning signals such as the variance of a… read more here.

DOI: 10.1073/pnas.2215667120
Abstract: In semiarid regions, vegetated ecosystems can display abrupt and unexpected changes, i.e., transitions to different states, due to drifting or time-varying parameters, with severe consequences for the ecosystem and the communities depending on it. Despite… read more here.

DOI: 10.1103/physreve.106.054412
Abstract: Complex spatial systems can experience critical transitions or tippings on crossing a threshold value in their response to stochastic perturbations. While previous studies have well characterized the impact of white noise on tipping, the effect… read more here.

DOI: 10.1111/gcb.15118
Abstract: Abstract Mountain forests are at particular risk of climate change impacts due to their temperature limitation and high exposure to warming. At the same time, their complex topography may help to buffer the effects of… read more here.

DOI: 10.1111/gcb.15815
Abstract: Natural systems can undergo critical transitions, leading to substantial socioeconomic and ecological outcomes. 'Ecological resilience' has been proposed to describe the capacity of natural systems to absorb external perturbation and reorganize while undergoing change so… read more here.
