title: Data from: Landscape heterogeneity can partially offset negative effects of habitat loss on mammalian biodiversity in agroecosystems

description: Intensive, large-scale agriculture promotes the conversion of natural
 habitats and diversified crops into monocultures, decreasing both native
 vegetation cover and landscape heterogeneity, leading to landscape
 simplification. Yet, a key knowledge gap persists on the relative impacts
 of the loss of native vegetation and landscape heterogeneity on
 biodiversity. Addressing this gap is pressing to support policies that
 conciliate agricultural production and biodiversity conservation and to
 move forward some scientific controversies, as the “land sharing versus
 land sparing” and “habitat loss versus fragmentation” debates.Through a
 hierarchical sampling design that maximized variation, while minimizing
 correlation, between landscape heterogeneity and native vegetation cover,
 we recorded the occurrence of medium and large-bodied mammals in native
 vegetation and agricultural areas of 55 landscapes in a global
 conservation hotspot and a key commodity production area – the Brazilian
 savanna, Cerrado. We compared simple, additive, and interactive models to
 investigate the effects of landscape heterogeneity and native vegetation
 cover on richness and composition of native and invasive
 mammals. Native and invasive mammal communities were affected by
 both native vegetation cover and landscape heterogeneity, although the
 effects of the first was stronger than the later. Both aspects had
 positive effects on native species richness and negative on invasive
 species richness, indicating that the loss of native vegetation and the
 reduction in landscape heterogeneity lead to biotic homogenization. Yet,
 while landscape heterogeneity benefited most native species, the direction
 of its effect varied among invasive species and depended on native
 vegetation cover.Synthesis and applications: Besides reducing habitat
 loss, avoiding landscape homogenization is key for conciliating
 agricultural production and biodiversity conservation, pointing to the
 relevance of policies encouraging crop diversification. As increasing
 landscape heterogeneity can in part compensate the negative effects of
 losing native habitat on biodiversity in agroecosystems, policies can gain
 feasibility by adjusting the balance between native vegetation cover and
 landscape heterogeneity according to what best suits local restraints and
 demands.

The columns represent each mammal's species detection (0 or 1) and the native and invasive species richness (number of native or invasive species detected per landscape). The scientific names of the species are indicated in the column names. Three species are invasive: Sus scrofa, Canis lupus familiaris, and Lepus europaeus. The data was collected using camera traps and transects (3 camera stations and 9 transects per landscape). ## Code/Software Analyzes were performed in R environment with 'MuMIn' package (Barton, 2022) and 'psych' package (Revelle, 2022).
