Study of the influence of the phylogenetic distance on the interaction network of mutualistic ecosystems
(Elsevier Science, 2014-01)
We investigate how the phylogenetic relationship between the species of each interacting guild in a mutualistic ecosystem influences its network of contacts. We develop a dynamical self organized model that reallocates ...
Abiotic factors shape temporal variation in the structure of an ant-plant network
Despite recognition of key biotic processes in shaping the structure of biological communities, few empirical studies have explored the influences of abiotic factors on the structural properties of mutualistic networks. ...
MODULAR: software for the autonomous computation of modularity in large network sets
Disentangling the co-structure of multilayer interaction networks: degree distribution and module composition in two-layer bipartite networks
(Nature Publishing Group, 2017-11)
Species establish different interactions (e.g. antagonistic, mutualistic) with multiple species, forming multilayer ecological networks. Disentangling network co-structure in multilayer networks is crucial to predict how ...
Merging evolutionary history into species interaction networks
(Wiley Blackwell Publishing, Inc, 2016-05)
1. The occurrence of complex networks of interactions among species not only relies on speciesco-occurrence, but also on inherited traits and evolutionary events imprinted in species phylogenies.The phylogenetic signal ...
Changes of a mutualistic network over time: reanalysis over a 10-year period
(ECOLOGICAL SOC AMER, 2010)
We analyzed the structure of a multispecific network or interacting ants and plants bearing extrafloral nectaries recorded in 1990 and again in 2000 in La Mancha, Veracruz, Mexico. We assessed the replicability of the ...
Evolution and coevolution in mutualistic networks
A major current challenge in evolutionary biology is to understand how networks of interacting species shape the coevolutionary process. We combined a model for trait evolution with data for twenty plant-animal assemblages ...
A network analysis of plant-pollinator interactions in temperate rain forests of Chiloé Island, Chile
This study characterizes the structure of a plant-pollinator network in a temperate rain forest of Chiloé Island, southern Chile, where woody species are strongly dependent on biotic pollinators, and analyzes its robustness ...
The nested structure of marine cleaning symbiosis: is it like flowers and bees?
