In natural communities, species interact with each other in different ways, including predation, competition, and facilitation. 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, as well as their consequences for community dynamics. Improving our understanding of the dynamics and resilience of complex ecological systems may rely on how the joint effects of different interactions types explain variations not explained by feeding interactions alone. In this talk, I’ll present recent efforts in analyzing and understanding ecological networks including different types of species interactions. I will argue that moving beyond unidimensional analyses of ecological networks may contribute to improving our understanding and predictive capacity of the way ecological systems respond to disturbances.
