Webnestedness analysis was seen as a tool to identify ordered sequences of extinction and colonization on true islands (Patterson 1987) and habitat islands (Patterson & Atmar 2000). Webmetric that matches with the concept of nestedness and compare its behavior with that of other metrics through analysis of model matrices ranging from highly-nested structures to alternative structures in which no degree of nestedness should be detected. In addition, we perform a test to verify whether the new metric correctly detects come into contact with each other
