Different reactions of plants and insect taxa to reduction of stocking rate: a concrete reason to promote habitat heterogeneity in grazing systems

摘要：

Preservation of habitat heterogeneity is an empirical rule that has been frequently proposed as a key for restoring and sustaining biodiversity in temperate agricultural systems.However, only few targeted experiments allow to support this hypothesis and to make practical management implications on the basis of reliable data.During five years, we measured biodiversity in a species‐rich mountain pasture grazed by cattle under three different stocking rates.We opted for recording taxa with different ecological characteristics (shopping‐basket approach) to test for more general and applicable patterns of diversity in relation to a reduction of stocking rate.
