Data for: Functional redundancy of weed seed predation is reduced by intensified agriculture

Intensive agriculture, a driver of biodiversity loss, can diminish ecosystem functions and their stability. Biodiversity can increase functional redundancy and is expected to stabilize ecosystem functions. Few studies however have explored how agricultural intensity affects functional redundancy and its link with ecosystem function stability. Here, within a continent-wide study, we assess how the functional redundancy of seed predation is affected by agricultural intensity and landscape simplification. By combining carabid abundances with molecular gut content data, functional redundancy of seed predation was quantified for 65 weed genera across 60 fields in four European countries. Across weed genera, functional redundancy was reduced with high field management intensity and simplified crop rotations. Moreover, functional redundancy increased the spatial stability of weed seed predation within fields. We found that ecosystem functions are vulnerable to disturbance in intensively manage..., This dataset contains information on the functional redundancy of seed predation for 65 weed genera and field estimates of weed seed predation. It also contains data on two aspects of agricultural intensity (field management intensity, measured as the number of field visits by the farmer to conduct operations, and crop rotation diversity) and two aspects of landscape simplification (the proportion of semi-natural habitat surrounding each field, and the length of the interface between crops and semi-natural habitat). The data were collected in 2018 from 60 cereal fields located in four European countries. Data organisation and analysis were conducted in Microsoft Excel and R. The primary objective of the data was to investigate the impact of agricultural intensity and landscape simplification on the functional redundancy of seed predation and to explore the link between functional redundancy and spatial stability (degree of within-field spatial variability) of field estimates of seed pre..., , # Data for: Functional redundancy of weed seed predation is reduced by intensified agriculture

This dataset was created as part of the research project BioAWARE “Could Biodiversity Assure Weed regulation for Resilient Ecosystem service provision?” Field data were collected from 60 cereal fields in four European countries (France, Austria, Czech Republic, and Sweden) between May and July 2018.

1. Estimating, analysing, and visualising the relative proportion of variance in predation redundancy across 65 weed genera attributed
to two aspects of agricultural intensity (field management intensity, and crop rotation diversity), two aspects of landscape simplification ( the proportion of semi-natural habitat and the length in meters of the interface between crop and semi-natural habitat), and the country-level random effect.
