WebNov 1, 2014 · In this study, we introduce a framework to investigate regime shifts in diatom assemblages and mangrove ecosystem dynamics in a coastal lagoon from the Galápagos Islands over the past 2600 years. The framework integrates a set of established statistical methodologies for investigating regime shift dynamics in long-term ecological records. WebJul 16, 2013 · Last year, Rong Wang and colleagues (Wang et al., 2012) published a very nice paper in Nature, which claimed to have observed flickering, an early warning indicator of an approaching critical transition, in a diatom sediment sequence from Erhai Lake, Yunnan, China.
