Increasing crop heterogeneity enhances multitrophic diversity across agricultural regions
Open accessAbstract
Significance: Agricultural landscape homogenization is a major ongoing threat to biodiversity and the delivery of key ecosystem services for human well-being. It is well known that increasing the amount of seminatural cover in agricultural landscapes has a positive effect on biodiversity. However, little is known about the role of the crop mosaic itself. Crop heterogeneity in the landscape had a much stronger effect on multitrophic diversity than the amount of seminatural cover in the landscape, across 435 agricultural landscapes located in 8 European and North American regions. Increasing crop heterogeneity can be an effective way to mitigate the impacts of farming on biodiversity without taking land out of production.

This loss of host plant diversity can impose negative downstream effects on key ecosystem players such as pollinators and other non-target organisms.
“This loss of host plant diversity can impose negative downstream effects on key ecosystem players such as pollinators and other non-target organisms ( 117 )”
From Environmental impacts of genetically modified crops (2024) · cites this paper as [117]
The Results and Discussion (pp. 3–5) link crop heterogeneity to species richness across bees, butterflies, hoverflies, and other taxa, supporting the general concern about effects on these organisms. But the paper studies crop diversity and field size, not a downstream effect caused specifically by loss of host plant diversity. It also finds that the effect of crop diversity depends on seminatural cover (Results and Discussion, p. 4). (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
