Evolutionary arms race in ant-ant mimicry: Camponotus lateralis lags behind in mimicking color patterns and sizes of regional Crematogaster models.
Article in Scientific reports, 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
Over a century ago, biologists proposed the Mediterranean ant Camponotus lateralis mimicked the coloration of the common and unpalatable ant Crematogaster scutellaris. A more recent hypothesis suggested that Ca. lateralis also mimicked the color of two additional models, Cr. schmidti and Cr. ionia, in their respective range. This study aims to test the hypothesis using red-green-blue values of 573 model and 957 mimic individuals and whether also size is affected by mimicry. The results support the regional-mimicry hypothesis: Camponotus lateralis is phenotypically more similar to syn- than to allotopic models. However, regional mimics evolutionarily lag behind the stronger radiated color and body-size traits of the models. Camponotus lateralis mimicked the coloration of the West Mediterranean species Cr. scutellaris least accurately, pointing to the possibility that the East Mediterranean species Cr. schmidti and Cr. ionia are the primary models, and Cr. scutellaris entered the system at a later stage. Fascinatingly, the example of Ca. lateralis is one of several analogous cases of convergent color evolution in camponotine ants that mimic Crematogaster models of different coloration. The unusually strong discriminant power of color variables in Crematogaster models-only partially replicated by their mimics-indicates a chase-away dynamic in response to Batesian mimicry.
