New reference genome assembly for the declining American Bumble Bee, Bombus pensylvanicus.
Article in G3 (Bethesda, Md.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
We present the first chromosome-level genome assembly for Bombus pensylvanicus, a historically widespread native pollinator species that was distributed across eastern North America but has subsequently undergone declines in range area and local relative abundance. This species has been of significant interest as a model for understanding both patterns and possible causes of bumble bee decline in the region, including the role of genetic variation. Here we present a chromosome-level reference genome assembled using Pacific Biosciences singe-molecule HiFi sequences and Hi-C data and annotated using evidence derived from RNA sequencing of multiple tissue types. The B. pensylvanicus genome has a total length of ∼352.6 Mb and was assembled into a total of 224 scaffolds, with 19 primary pseudomolecules representing putative chromosomes and an N50 = 14.872 Mb. Annotation with the Eukaryotic Genome Annotation Pipeline-External (EGAPx) identified 11,411 genes (10,263 protein coding), and BUSCO analysis of 5,991 Hymenoptera-specific BUSCO groups indicated a completeness for the proteins of 99.0% (98.6% single-copy, 0.5% duplicated) and for the genome of 98.5% (98.2% single-copy, 0.3% duplicated). We present synteny analyses with other recently assembled Bombus genomes representing different subgenera and examine the distribution of repetitive regions of the genome relative to the distribution of genes and noncoding RNAs.
