Abstract

fetched live from OpenAlex

溪流等足目动物 Lirceus 的丰富和颗粒组成生长在水源或泉水我们到在 3 的 2002 年 8 月的从 2001 年 4 月的 reinvestigated 在南部的安大略流,当前的速度的 Canada.Effects 被选择慢廉免除分析。等足目动物的底层,丰富上的季节和水深度,分发和颗粒组成的效果被分析。它被发现那底层和季节影响等足目动物大多数。有依附的细丝状的宏水藻的岩石底层包含等足目动物丰富 7.05 次光秃秃的岩石底层和 14.6 次的的好沙并且泥底层。关于在等足目动物的丰富和颗粒组成的 seasonality 有一个大变化,与发生在夏天的最高的丰富并且在冬季和春天最低;单个等足目动物也趋于在冬季和春天更大。在所有底层,浅区域趋于比更深的区域支持等足目动物的更高的密度。

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.
