Configurational heterogeneity drives songbird diversity at distinct spatial scales in managed boreal forests.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Context: Parsing scale-dependent responses of wildlife communities to mosaic landscapes is key to evaluating conservation outcomes of natural resource development. Objectives: We evaluate how spatial heterogeneity of harvest plans and oil and gas activity influence local boreal songbird species richness at ecologically relevant spatial extents. Methods: We implemented a multi-scale framework by varying extents at which species richness and landscape configuration metrics are measured. Birds were surveyed with Passive Acoustic Monitoring (PAM) in harvest plots across forested zones of Alberta, Canada, and species richness counted at 13 increasingly broad extents. For five configuration metrics, multiple landscape extents were compared to identify scale of effects unique to each response extent. Results: Four of five metrics converged on a domain boundary at 11-14 ha. Below this threshold, within-harvest heterogeneity indexing linear features and residual retention-edge density and Shannon diversity-drove species richness. Above it, mosaic configuration metrics (patch size variation, shape complexity) became influential alongside edge density and Shannon diversity. No single landscape extent was associated with species richness across response extents. Conclusions: Effects of landscape heterogeneity on songbird diversity at within-harvest and mosaic scales can be detected from individual PAM surveys when survey extent is appropriately constrained. Empirically identifying the spatial extents at which community diversity responds to configuration allows forest planners to match monitoring design and management actions to the scale at which they will have the greatest effect.
