摘要

Along with natural vegetation remnants, live fences in agricultural landscapes are elements that delimit crop fields and conserve biodiversity. In this study, we assessed plant and beetle (Coleoptera) diversity and composition in 16 sampling transects in remnant shrubland fragments, barley crops, and complex and simple live fences within an agricultural landscape in Central Mexico. We sampled plants in 80 subplots (1 × 10 m), and beetles with 96 pitfall traps. We recorded 54 plant species from 24 families, and 9,209 beetles belonging to 168 morphospecies from 27 families. We found that habitat complexity of shrubland remnants and complex live fences supported higher cumulative richness of plants and beetles than barley crops and simple live fences, and species composition varied across vegetation types. Moreover, our results show that intensive barley crops lead to biotic homogenization, whereas live fences (both complex and simple) and shrubland remnants conserve high plant and beetle beta diversity. Soil hardness is the main environmental variable influencing plant and beetle communities. This study highlights the importance of live fences’ complexity in maintaining biodiversity in agricultural landscapes; therefore, we recommend their inclusion as key elements in incentives for agricultural management policies and in territorial planning at different governance levels.
