Ecological networks, nestedness and sampling effort

1. Ecological networks have been shown to display a nested structure. To be nested, a network must consist of a core group of generalists all interacting with each other, and with extreme specialists interacting only with generalist species. 2. Studies on ecological networks are especially prone to...
