Graph theory is a powerful body of mathematical knowledge, based on simple concepts, in
which structural units are depicted as nodes with relationships between them depicted as …

Different species are of different importance in maintaining ecosystem functions in natural
communities. Quantitative approaches are needed to identify unusually important or …

Ecological networks are often composed of different subcommunities (often referred to as
modules). Identifying such modules has the potential to develop a better understanding of …

Aim Biotic interactions–within guilds or across trophic levels–have widely been ignored in
species distribution models (SDMs). This synthesis outlines the development of 'species …

We use a graph‐theoretical landscape modeling approach to investigate how to identify
central patches in the landscape as well as how these central patches influence (1) …

Modularity is a recurrent and important property of bipartite ecological networks. Although
well‐resolved ecological networks describe interaction frequencies between species pairs …

Various definitions and indices have been proposed in the literature to identify keystone
species. In this study, we intended to make the concept of keystone species operational for …

Abstract Analysis of plant–frugivore interactions provides a quantitative framework for
integrating community structure and ecosystem function in terms of how the roles and …

We review the main results from the literature on the consequences of link and node
removal in real social networks. We restrict our review to only those works that adopted the …

Analysis of the structure and function of urban metabolic systems is an important goal of
urban research. We used network pathways and network utility analysis to analyze the basic …
