Relationships between the distribution of wildlife and livestock diversity.

Aim: Wild biodiversity and agrobiodiversity are affected by challenges such as agricultural intensification. However, it is unknown whether or not both components of biodiversity respond similarly to environmental factors and to these challenges. Here, we examine the spatial relationships between the distributions of wild biodiversity and agrobiodiversity, to quantify how and where they covary across the geography. Location: Mainland Spain, a European region that harbours high values of both wild and agro‐ biodiversity. Methods: We used geographically weighted regression models to analyse the spatial variation in the relationships between the distribution of wild vertebrates and environmental and agrobiodiversity variables. We modelled the spatial gradients in species richness of native terrestrial vertebrates—that is, specific groups of amphibians, reptiles, birds and mammals—as a function of local livestock breed richness—that is, bovine, ovine, caprine, asinine, equine and porcine—climate variables and human footprint. Results: We found significant covariation between the distribution of native vertebrate species richness and climate, human footprint and livestock diversity. Overall, the association between species richness of the four wild terrestrial vertebrate groups and local livestock breed richness is positive across most of the studied area. However, local breed richness of cattle and sheep breed displays contrasting patterns, where cattle breeds associate positively to most wildlife vertebrates and sheep breeds show negative associations. Main conclusion: Wildlife diversity distributions are significantly associated with livestock agrobiodiversity. These spatial relationships are mediated by large‐scale environmental gradients. Since both, wildlife and livestock agrobiodiversity, tend to co‐occur spatially, future strategies for conservation in agricultural landscapes could benefit from integrated approaches.
