“…ENSO variability was weakened under early Holocene orbital forcing, with high variability emerging only in the last few thousand years (41). Future climate change will be the product of natural variability acting over multiple spatial and temporal scales superimposed on anthropogenic trends.…”

Climate change in the coming centuries will be characterized by interannual, decadal, and multidecadal fluctuations superimposed on anthropogenic trends. Predicting ecological and biogeographic responses to these changes constitutes an immense challenge for ecologists. Perspectives from climatic and ecological history indicate that responses will be laden with contingencies, resulting from episodic climatic events interacting with demographic and colonization events. This effect is compounded by the dependency of environmental sensitivity upon life-stage for many species. Climate variables often used in empirical niche models may become decoupled from the proximal variables that directly influence individuals and populations. Greater predictive capacity, and morefundamental ecological and biogeographic understanding, will come from integration of correlational niche modeling with mechanistic niche modeling, dynamic ecological modeling, targeted experiments, and systematic observations of past and present patterns and dynamics.biogeography ͉ climate change ͉ paleoecology ͉ regeneration niche

“…While natural ENSO variability through the mid-Holocene to today is currently debated, the common viewpoint is that optimum conditions prevailed during the midHolocene, when ENSO variability is considered to have been greatly reduced (Braconnet et al, 2011;Chiang et al, 2009;Cobb et al, 2013;Donders et al, 2008).…”

“…drought events, and increased run-off into the Bay (Donders et al, 2008;Lybolt et al, 2011). Furthermore, environmental conditions were exacerbated by gradually falling sea level by approximately two metres to present day levels, during the Late Holocene ( Figure 2) (Lewis et al, 2008;Sloss et al, 2007).…”

“…Our chronological study begins ~7.4 cal ka yBP during the mid-Holocene climatic optimum (Donders et al, 2008;Lybolt et al, 2011;Neil, 1998). We expected to see a response by foraminifers to ENSO-deterioration in climate, instead we find that conditions were predominantly and consistently marginal for photosymbiont activity for most of the Holocene timeframe investigated by this study.…”

“…The mid-Holocene subtropical terrestrial habitats of SE Queensland shifted from a humid, rainforest-dominated ecosystems with high lake levels and low fire frequency to an arid, open environment with drought resistant vegetation, decreased lake levels and increased fire frequency around 5 cal ka yBP (Donders et al, 2007;Donders et al, 2008;Harrison, 1993). A second phase of climatic deterioration and increased aridity followed intensification of ENSO after 3 cal ka yBP (~1000 BCE) and coincides approximately with reef "gap" 2 (Phase 2b)" following Phase 2(a) (Figure 2) (Donders et al, 2007).…”

The El Niño–Southern Oscillation (ENSO) exerts significant control over the amount of Florida winter precipitation. We use a local near‐annual resolved palaeobotanical proxy record from southern Florida to test for historic ENSO variability over the past 125 years. Palaeobotanical proxies from a Florida wetland, pollen counts, and a new drought‐stress proxy based on leaf epidermal cell densities are used as indicators of moisture availability during the winter growing season. Spectral analysis and band‐pass filtering of the proxy records reveal significant variability within the 2–7 year bandwidth characteristic of ENSO, as well as decadal signatures. A maximum likelihood palaeoprecipitation reconstruction of the pollen record based on modern vegetation distributions shows values and variability comparable to instrumental records. The approach shows the dominant control of ENSO on Florida vegetation and provides a powerful means to detect discrete ENSO variability in older intervals.
