Are threatened species important for glueing interaction networks together?
González-del-Pliego, Pamela; Galiana, Nuria; González-Trujillo, Juan David; Mestre, Frederico; Bastos Araújo, Miguel; Bastazini, ViniciusBiotic interactions are a critical element for the functioning and the stability of ecosystems, yet anthropogenic pressures can significantly disrupt these networks of interacting species. While species-focused conservation is central to most conservation policy, it is also vital to identify the interactions at risk and the ones that play a disproportionate role in glueing communities together. Here we assess t...
Ecological network complexity scales with area.
Galiana, Nuria; Lurgi, Miguel; Bastazini, Vinicius; et al.Larger geographical areas contain more species—an observation raised to a law in ecology. Less explored is whether biodiversity changes are accompanied by a modification of interaction networks. We use data from 32 spatial interaction networks from different ecosystems to analyse how network structure changes with area. We find that basic community structure descriptors (number of species, links and links per s...
