Temperate forest heterogeneity decreases local and landscape‐scale spider diversity through habitat filtering despite increasing species turnover

Journal of Animal Ecology, EarlyView.
In a large‐scale German forest experiment, habitat heterogeneity increased spider turnover but reduced local alpha diversity through habitat filtering. Together, these effects lowered landscape‐scale spider diversity. As such, the study shows whether environmental heterogeneity increases or decreases biodiversity depends on the balance between habitat ...
