"Study of the influence of the phylogenetic distance on the interaction network of mutualistic ecosystems"
Roberto P.J. Perazzo, Laura Hernández, Horacio Ceva, Enrique Burgos and José Ignacio Alvarez-Hamelin
Physica A 394 (2014) 124-135
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 contacts between mutualists, according to a contact preference rule (CPR) that takes into account phylogenetic distances. We conclude that a CPR that promotes phylogenetic proximity among the counterparts of the species of each guild leads to highly unrealistic contact patterns. We find that nestedness can instead be attributed to a general rule by which species tend to behave as generalists holding contacts with counterparts that already have a large number of contacts.
