Diatom flickering prior to regime shift
WebMay 16, 2024 · The diatom to diatom-dinoflagellate shift was significantly associated with the DN regime shift of oxidized nitrogen (NO 3-N) to reduced nitrogen (NH 4-N and dissolved organic nitrogen [DON]) since the mid-1990s. WebOct 3, 2014 · Increasing variance, skewed responses, and kurtosis in time-series data may be indicative of flickering, the rapid alternating between two different states prior to a regime shift . Along with autocorrelation at lag-1, increasing variance in time-series data can be caused by critical slowing down, where a system is slow to recover from minor ...

WebJan 5, 2015 · Here we used the phytoplankton colour index, a visual biomass estimate, from 1948 to 2010 and total diatom abundance from 1958 to 2010 to test whether the well-documented regime shift could have been anticipated by the recently developed Early-Warning Signals for critical transitions (EWS). 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.
