Abstract

fetched live from OpenAlex

Abstract Primary production and decomposition by microbial communities underpins the functioning of terrestrial and aquatic ecosystems. Microbial communities also provide economically important services such as degradation of pollutants; direct effects on primary productivity; and indirect effects of predation, phytophagy, or resource competition. This chapter's review recent experiments with constructed communities of microbes under controlled conditions. Our review reveals that, although there are many exceptions, most studies have demonstrated a positive relationship between microbial diversity and ecosystem functioning. However, studies of natural communities have reported a variety of relationships between microbial diversity and functioning, and no consistent evidence for a significant relationship has emerged. Regarding these inconsistencies, This chapter discusses the possibility that microcosm and field studies are investigating different parts of the same underlying relationship, and also the possibility that bias in microbe culturability or error in field measurements of biodiversity make comparisons difficult.

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.
