Résumé

Context: Alteration of natural vegetation cover across the landscape drives biodiversity changes. Although several studies have explored the relationships between vegetation cover and species richness, as well as between land-cover variance and species richness, few have considered the non-independence of these two biodiversity drivers. Objectives: The goal of this perspective paper is to present theoretical and empirical relationships linking vegetation cover to land-cover variance at the landscape scale, and the implication of these relationships for species richness change along a gradient of increasing anthropization. Methods and results: We used simulated and empirical Normalized Difference Vegetation Index data to examine the generality of the relationship between vegetation cover and land-cover variance. Using the province of Québec (Canada) as a case study, our results show that decreasing vegetation cover captures the transition from landscapes with low land-cover variance (non-anthropized landscapes), to intermediate variance (agricultural landscapes), to high variance (urban landscapes). Conclusion: Based on this relationship between vegetation cover and land-cover variance, and assuming independent positive monotonic relationships between biodiversity and both of these drivers, we predict a unimodal relationship between species richness and anthropization. This suggests a threshold of anthropization beyond which the positive effects of land-cover variance no longer compensate for the negative effects of vegetation cover loss. Identifying these thresholds could be key to setting conservation targets at a landscape scale. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
