Also in line with the convention, an eighth food web property, connectance, is inferred to be scale-dependent and to decrease as the number of species increases (2). I have ...
متن کاملEffects of spatial scale of sampling on food web structure
This study asks whether the spatial scale of sampling alters structural properties of food webs and whether any differences are attributable to changes in species richness and connectance with scale. Understanding how different aspects of sampling effort affect ecological network structure is important for both fundamental ecological knowledge and the application of network analysis in conserva...
