Pollinator Dependency and Regional Climate Affect Crop Yield Development Under Climate Change.
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
Climate change is severely impacting insects and flowering plants in different ways. While effects on plants, pollinators and their interactions have been amply discussed, subsequent impacts on pollination are rarely assessed. Understanding climate-change effects on pollination is particularly important for insect-pollinated crops as it ultimately influences yield and hence food production. This study investigated crop-yield changes over 35 years in two climatically distinct regions in Germany (cool-moist vs. warm-dry). Yield differences among crops showing different levels of pollinator dependency (none, moderate, strong) were analysed in correlation with time (indirect climate-change measure) and a composite climate parameter (direct measure). Despite rising temperatures and droughts, yields in both regions increased over time across pollinator-dependency classes, likely due to increased productivity through technological advances. Marked differences in yield optima based on pollinator dependency and region were found in complementary, time-independent climate correlations. Long-term average values exceeded optimal yield conditions for moderately pollinator-dependent plants. Surprisingly, crops that strongly depend on pollinators showed increased yields with warmer, drier conditions, possibly due to fewer late frost events and climate-driven pollinator community shifts.
