| Summary: | Species are linked to each other by a myriad of positive and negative interactions. This complex spectrum of interactions constitutes a network of links that mediates ecological communities’ response to perturbations, such as exploitation and climate change. In the last decades, there have been great advances in the study of intricate ecological networks. We have, nonetheless, lacked both the data and the tools to more rigorously understand the patterning of multiple interaction types between species (i.e., “multiplex networks”), as well as their consequences for community dynamics. Using network statistical modeling applied to a comprehensive ecological network, which includes trophic and diverse non-trophic links, we provide a first glimpse at what the full “entangled bank” of species looks like. The community exhibits clear multidimensional structure, which is taxonomically coherent and broadly predictable from species traits. Moreover, dynamic simulations suggest that this non-random patterning of how diverse non-trophic interactions map onto the food web could allow for higher species persistence and higher total biomass than expected by chance and tends to promote a higher robustness to extinctions. : ReadMeAdjacency matrix for the trophic layerThe file is TAB-delimited and contains 107 lines and 108 columns. The first line is composed by two TAB-keys followed by the numerical IDs of the 106 species. The 106 following lines are composed as follows. The first and second columns display the numerical ID and the name of the species respectively. The species name can include whitespace characters. The remaining columns are the adjancency matrix values, i.e. 1/0 for presence/absence of a link. A link between species i and j means species i is eaten by species j.chilean_TI.txtAdjacency matrix for the positive non-trophic layerSame format as chilean-TI.txt.
