Abstract

fetched live from OpenAlex

Peatlands have been widely studied in terms of their ecohydrology, carbon dynamics, ecosystem services and palaeoenvironmental archives. However, several assumptions are frequently made about peatlands in the academic literature, practitioner reports and the popular media which are either ambiguous or in some cases incorrect. Here we discuss the following ten common assumptions about peatlands:\n\n 1. the northern peatland carbon store will shrink under a warming climate;\n\n 2. peatlands are fragile ecosystems;\n\n 3. wet peatlands have greater rates of net carbon accumulation;\n\n 4. different rules apply to tropical peatlands;\n\n 5. peat is a single soil type;\n\n 6. peatlands behave like sponges;\n\n 7. Sphagnum is the main ‘ecosystem engineer’ in peatlands;\n\n 8. a single core provides a representative palaeo-archive from a peatland;\n\n 9. water-table reconstructions from peatlands provide direct records of past climate change; and\n\n10. restoration of peatlands results in the re-establishment of their carbon sink function.\n\nIn each case we consider the evidence supporting the assumption and, where appropriate, identify its shortcomings or ways in which it may be misleading.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
