Relative abundance patterns of terrestrial arthropods in Mojave National Preserve
Bibliographic record
Abstract
In dryland systems, shrubs often increase the productivity, abundance, and diversity of understory plants, however these positive interactions can also scale to other trophic levels. The facilitative effect of Larrea tridentata was hypothesized to extend beyond plants to the local insect community in the Mojave Desert. Pan traps were placed under shrubs and in open microsites to test the following predictions: 1) shrub-annual facilitation complexes increase insect abundance, richness, and diversity; and 2) specific insect families or functional groups respond to the shrub-annual facilitation complex more strongly due to increased resources. Abundance, richness, and diversity of the insect commu- nities associated with shrubs were significantly greater in shrub compared to open microsites. The families Sphecidae, Formicidae, Bradynobaenidae and Lauxaniidae were positively associated with shrubs while Scarabaeidae was associated with open microsites. However, there was no difference in the relative abundances of major functional groups, suggesting that the primary pollinators for this ecosystem are not sensitive to differences in floral resources at this scale. This study demonstrates that shrubs facilitate local insect communities and supports the hypothesis that plant-plant facilitation can extend to other trophic levels. Management of desert shrubs is thus an effective means to enhance many components of insect biodiversity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
