Taxonomic Bias Persists in Ecology and Evolution Research Despite Decades of Concern.
Article in Ecology and evolution, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Scientific hyperfocus on certain organisms slows innovation and hinders the generality of ecological and evolutionary inference. Yet, the extent of taxonomic bias in this research field and its potential changes over time remain poorly quantified. By assessing 1,383,803 papers and 612 journals, we show that ecology and evolution research is strongly taxonomically biased. We found that the prevalence of studies on vertebrates in the literature as a whole (but not within some pockets of ecology and evolution) has remained similar since the early 2000s, when the first studies of taxonomic bias were published. We also observed that studies on vertebrates, relative to those on invertebrates, were more prevalent in higher impact journals and, within journals, received more citations and mentions in the media. However, classifying animals into more specific groups led to context-dependent temporal and attention patterns. We propose a series of urgent targeted actions to ameliorate taxonomic imbalances in ecology and evolution.
