Abstract
Abstract By focusing on the horizontal distribution of Pleistocene vegetation types within tropical landscapes, we may be overlooking an equally important feature of palaeovegetation, namely their vertical structure. Tropical forest structure is a critical factor contributing to canopy microclimatology and thus plays a role in defining canopy habitats and species population dynamics. Because of this tight relationship between forest structure and canopy microclimate, flora and fauna with narrow canopy niches may have responded to glacial reductions in forest canopy density in the same manner as if the tropical forest were completely replaced by grassland. This alternative interpretation of palaeo‐forest response to past climate change holds significance for the application of the Pleistocene refugia hypothesis in explaining various biogeographical trends. The role of forest structure in influencing hydrological cycling and the exchange of carbon between the biosphere and atmosphere are highlighted to illustrate how palaeoprecipitation and palaeoproductivity proxy data may be misinterpreted when forest structure is not explicitly considered. This is accomplished through theoretical scenarios using hydrological mass balance equations and simulations using a soil–plant–atmosphere landscape model. Available methodologies to reconstruct tropical palaeovegetation structure are identified, including the use of fully coupled earth system models. Copyright © 2004 John Wiley & Sons, Ltd.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
