Reconstructing plant diversity from pollen records
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
The study faces the challenge of reconstructing plant diversity from pollen records. The research must account for the impact of human activities and climate change on vegetation dynamics. The study needs to disentangle the relative impacts of climate, fire, and anthropogenic disturbance on plant diversity.
Evidence profile
Sourced from the stated challenges and stated research gap of the source papers, classified as general, drawn from work published between 2025 and 2026, spanning 3 journals.

- Response and recovery of a Sphagnum peatland from long-term human-induced alkalinisation (2025) · Biogeosciences · doi
The study notes the challenge of temporal autocorrelation and boundary effects in the analysis of the data. The paper highlights the difficulty of achieving a target of 500 terrestrial pollen grains per sample due to low pollen concentrations in some core sections. The study acknowledges the need for more evidence to draw conclusive interpretations about recovery.

Key uncertainties include potential seasonal biases, the quality of available proxy datasets, and the definition and reliable detection of abrupt temperature or precipitation excursions. The paper identifies a gap in the reliable use of pollen data in climate reconstructions, particularly in the Carpathian region.
