Responses of alkaline phosphatase activity in Daphnia to poor nutrition.
Article in Oecologia, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The use of biochemical and molecular indices of nutritional stress have recently been promoted for their potential ability to assess the in situ nutritional state of zooplankton. The development and application of these indicators should at least consider the cross-reactivity with other nutritional stressors. We examined the potential usefulness of body alkaline phosphatase activity (APA) as an indicator of dietary phosphorus (P) stress in Daphnia. We measured growth rate, body P-content, and body APA of two species of Daphnia (D. magna, D. pulex) grown for different periods under diverse dietary conditions. We found P-poor food reduced daphnid growth rates and body P-content, while body APA increased in both species. However, body APA increased in P-sufficient D. magna and D. pulex that were feeding on cyanobacterial compared to green algal food, despite no differences in animal body P content. Body APA increased in D. magna fed P-poor food whether cyanobacterial or algal. Body APA also varied with age and other nutritional stresses (low food quantity, nitrogen-poor algae) in both daphnid species. Our results demonstrate that whole body homogenate APA in Daphnia is not singularly responsive to P-poor food, which will complicate or limit its future usefulness and application as an indicator of dietary P-stress in metazoans.
