Cyanobacterial protease inhibitors lead to maternal transfer of increased protease gene expression in Daphnia.
Article in Oecologia, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
Protease inhibitors (PIs) have frequently been found in cyanobacterial blooms and have been shown to affect the major herbivore Daphnia by decreasing growth and inhibiting gut protease activity. However, it has been shown that a clone of Daphnia is able to respond to dietary PIs by increasing its protease gene expression. Such an inducible response might be maternally transferred to the next generation. Therefore, we tested a tolerant clone for maternal transfer of protease gene expression. When exposed to the trypsin inhibitor-producing cyanobacterium Microcystis aeruginosa PCC7806 Mut, Daphnia mothers and their untreated newborns showed an increase in trypsin gene expression compared to naïve mothers grown on control food and their offspring. The maternally transferred increase in gene expression was accompanied by a higher somatic growth rate of the offspring generation from exposed mothers compared to offspring from naïve mothers. This higher growth rate compensated for the lower dry mass of newborns from exposed mothers and led to the same fitness as observed in the offspring of naïve mothers. In nature, clones that can maternally transfer increased protease gene expression should have an advantage over clones that cannot. The selection for such more tolerant clones by naturally occurring PIs might lead to microevolution of natural Daphnia populations, and to local adaptation in the long term. This is the first study to show an adaptive maternal transfer of increased target gene expression in an ecological context.
