DOI: 10.1007/s00442-018-4215-2
Abstract: Alternative stable state theory predicts that different disturbance regimes may support contrasting ecosystem states under otherwise analogous environmental conditions. In fire-prone systems, this theory is often invoked to explain abrupt ecotones, especially when adjacent vegetation… read more here.

DOI: 10.1016/j.gca.2020.02.021
Abstract: Abstract The East Anglian salt marsh system (UK) has recently generated intriguing data with respect to sediment biogeochemistry. Neighbouring ponds in these salt marshes show two distinct regimes of redox cycling: the sediments are either… read more here.

Abstract: A large amount of research has used the scale-free statistics of neuronal avalanches as a signature of the criticality of neural systems, which bears criticisms. For instance, the work of Touboul and Destexhe demonstrated that… read more here.

DOI: 10.1088/1361-665x/aa8282
Abstract: This paper presents a novel dielectric elastomer actuator (DEA) with three stable states. By introducing magnetic forces and coupling them with two cone dielectric elastomer (DE) films, an inherent tristability for the DEA is obtained… read more here.

DOI: 10.1098/rsos.211778
Abstract: Globally, forests and savannah are shown to be alternative stable states for intermediate rainfall regimes. This has implications for how these ecosystems respond to changing rainfall conditions. However, we know little about the occurrence of… read more here.

Abstract: We report the role of $\mathcal{PT}$-symmetry in switching characteristics of a highly nonlinear fiber Bragg grating (FBG) with cubic-quintic-septic nonlinearities. We demonstrate that the device shows novel bi-(multi-) stable states in the broken regime as… read more here.

DOI: 10.3398/064.078.0407
Abstract: Abstract. Kelp forest communities are highly variable over space and time. Despite this complexity it has been suggested that kelp forest communities can be classified into one of 2 states: kelp dominated or sea urchin… read more here.
