WebDec 1, 2014 · Take, for example, those lake compartments within the domain of alternative stable states of Fig. 1. If these compartments are part of a homogeneous lake, connectivity will lead to local resistance to perturbations because other compartments will continuously supply inputs corresponding to the prevalent state, which leads to rehabilitation of ... WebMar 3, 2024 · We illustrate this conceptual framework with examples from two well-defined alternative stable state systems—restoration of grasslands degraded by long-term grazing (Noy-Meir 1975, Suding and Hobbs 2009) and woody plant encroachment of grasslands (D'Odorico et al. 2012, Ratajczak et al. 2024a, 2024b). We then integrate these …

WebMar 9, 2024 · Examples of ecosystems with alternative stable states include drylands which can shift from shrub vegetation to desert (Kéfi et al., 2007), tropical forests that can switch from forest to savanna and back (Scheffer et al., 2014; Staver et al., 2011) and coral reefs that can shift from healthy coral dominance to being overgrown by macro-algae ... WebThe alternative stable states theory of shallow lakes As a starting point let us resume the central ideas behind the original alternative stable states the-ory for shallow lakes (Scheffer et al., 1993). This theory was inspired by observations that lakes tended to shift rather abruptly between a clear and a turbid state, and that once lakes turned

WebJun 30, 2016 · The theory of alternative stable states (Scheffer and others 2001) predicts that bistable systems can undergo a transition from one state to the other if environmental conditions (such as MAP) reach a so-called ‘tipping point.’
WebOct 27, 2024 · Large-scale empirical evidence for alternative stable states is limited, however, and comes mostly from the multimodal distribution of structural aspects of vegetation. These approaches have been criticized, as structure alone cannot separate out wetter savannas from drier forests for example, and there are also technical challenges … flights from cak to punta gordaWebMar 9, 2024 · We investigate whether evolution by natural selection along resource gradients leads to bistability, using shallow lakes as an example.
