Abstract

fetched live from OpenAlex

The diversity of taiga upland arachnid communities, collected mainly in pitfall or pan traps, is compared among forested habitats in two Manitoba regions, one southern and one northern.In the south, where collections were taken both in summer and in winter under the snow cover, the dominant spider families were Erigonidae, Linyphiidae, Lycosidae, and Gnaphosidae.The diurnal and nocturnal pursuit guilds dominated across habitats.In the north, with summer collecting only, dominant familes were Lycosidae, Gnaphosidae and Erigonidae of the diurnal pursuit guild.The southern taiga uplands had 99 species of spiders, northern uplands 49 species with 19 species common to both regions.The five most dominant species from these families are Agroeca ornata Banks, Gnaphosa microps Holm, Pardosa xerampelina (Keyserling), P. mackenziana (Keyserling), and Agelenopsis utahana (Chamberlin and Ivie).Three opilionid species occur in the south and one species, Odiellus pictus Wood, occurs in both regions.In this region of the taiga, we found the most species-rich habitats to be undisturbed forest types, i.e., alder-tamarack ecotone in winter, which produced 34 winter-active species (n=233), with 27 species collected only during winter months.Among-habitat differences in species richness, species dominance and guild composition suggests that maintenance of habitat heterogeneity is needed at all scales to preserve the diversity of forest floor arachnid communities in managed taiga forests.

Full frame distilled prediction

Teacher imitation

Not 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.
