Directed network Laplacians and random graph models
Royal Society Open Science, 2021 We consider spectral methods that uncover hidden structures in directed networks. We establish and exploit connections between node reordering via (a) minimizing an objective function and (b) maximizing the likelihood of a random graph model. We focus on

Biodiversity and community structure [PDF]
Proceedings of the National Academy of Sciences, 2021 In natural plant communities, one finds ample examples of both competitive and facilitative interactions. The effect of a species A on another species B is said to be competitive (facilitative) if an increase in A ’s population size reduces (enhances) the population growth rate of B .

Hierarchical community structure in complex (social) networks [PDF]
, 2014 The investigation of community structure in networks is a task of great importance in many disciplines, namely physics, sociology, biology and computer science where systems are often represented as graphs.

Estimating carnivore community structures [PDF]
Scientific Reports, 2017 AbstractObtaining reliable estimates of the structure of carnivore communities is of paramount importance because of their ecological roles, ecosystem services and impact on biodiversity conservation, but they are still scarce. This information is key for carnivore management: to build support for and acceptance of management decisions and policies it ...

Coral bacterial community structure responds to environmental change in a host-specific manner
Nature Communications, 2019 The global decline of coral reefs heightens the need to understand how corals respond to changing environmental conditions. Corals are metaorganisms, so-called holobionts, and restructuring of the associated bacterial community has been suggested as a ...

Immunization of networks with non-overlapping community structure [PDF]
Social Network Analysis and Mining, 2018 Although community structure is ubiquitous in complex networks, few works exploit this topological property to control epidemics. In this work, devoted to networks with non-overlapping community structure (i.e., a node belongs to a single community), we ...
