Abstract
The relationship between species and habitat is an essential topic in animal conservation. Species live in a habitat that provides food and contributes to the habitat. This relationship can be modelled as a graph with two types of vertices, known as a bipartite graph. Graph G=(V,E) is an ordered pair of the vertex set V and edge set E such that E⊆-[V]^2. In the habitat species network, vertices represent species or habitats. The vertices representing species are called species vertex sets (V_s), while the vertices representing habitats are called habitat vertex sets (V_h). The edge connecting a species vertex and a habitat vertex is defined as the species visiting that habitat. In this study, we used three similarity indices to describe the condition of several species or habitats in the Bungo area. These similarity indices are structural equivalence, Jaccard similarity, and Pearson correlation coefficient.
