Density of overwintering carabids (m-2)
Edges as overwintering sites for syrphid larvaefeeding on wheat aphids
Sarthou et al. 2005; Arrignon et al. 2007
Slow disturbance regime(~50 years)
Fast disturbance regime(~ once and more per year)
How to deal with spatial interfaces between several complex social-ecological dynamic systems?
How to improve the spatial resilience concept?
