    How macroorganisms affect the epilithic biofilm in the intertidal rocky shore? : trophic and non-trophic pathways
    (2021) Arboleda Baena, Clara María; Navarrete C., Sergio; Pontificia Universidad Católica de Chile. Facultad de Ciencias Biológicas
    The Trophic Networks (consumer-resource relationships) and Ecological Networks (trophic and non-trophic interactions) theories are approaches to studying complex systems that try to incorporate all, or at least a large part of all the species of animals and plants that coexist in a particular place or ecosystem. Among the most complete or well-documented marine ecological networks is the one of macroinvertebrates and macroalgae from the intertidal rocky shore of central Chile. In this ecological network and all the macroorganism networks that have been documented in the literature, microorganisms are represented as one or two homogeneous nodes. Still, these themselves represent complex communities composed of multiple species that interact with each other. This is the case of the epilithic biofilms, which are assemblages of microorganisms (Bacteria, Archaea, and Eukaryotes) united by extracellular polymeric substances (EPS) and adhere to abiotic surfaces such as rocks. The doctoral thesis entitled “How macroorganisms affect the epilithic biofilms in the intertidal rocky shore? Trophic and non-trophic pathways” highlights the importance of incorporating these microbial communities into the ecological network of the intertidal rocky shore of central Chile, presents an important diversity of interactions between macro-and microorganisms, complements the studies previously carried out in the system and generates new questions about the interactions between macro and microscopic components and the dynamics of coastal marine ecosystems.
