Abstract

Aquatic ecosystems play an important role in the cycling of energy and matter, and generally present high productivity and biodiversity. In tropical regions, these ecosystems are particularly relevant to biogeochemical cycles. Microorganisms play a central role in CO2 production and consumption processes in these ecosystems. However, little is known about the phylogenetic diversity of these microorganisms and their biotic interaction with other compartments of the planktonic food web, as well as the processes behind the high CO2 emissions observed in tropical aquatic ecosystems. The proposed research will quantify biomass stocks, processes (e.g. production, respiration) and interactions between the different compartments of the planktonic microbial food web in samples from a large number of aquatic environments in the state of São Paulo, and a time series in Broa reservoir. These field data, combined with experiments in controlled laboratory conditions (microcosm) and field experiments (mesocosms), will allow evaluating the influence of classical food chain community structure (phytoplankton, zooplankton and fish) on microbial food web compartments. On the other hand, the study of biodiversity of planktonic microbial communities (prokaryotes and eukaryotes) and the relationships of its dynamics with environmental factors through next generation sequencing techniques (marker genes and metagenomics), will allow a characterization of the community structure and ecological functioning of microbial assemblies, but also obtaining patterns of co-occurrence or covariance between microorganisms and other larger organisms of different food web compartments (allowing the construction of interaction networks). These results will allow testing the robustness of some ecological theories (mainly developed for animals and plants) in microbial systems and clarify the mechanisms behind the high CO2 emissions observed in tropical aquatic ecosystems. This proposal aims to implement a new research line in the DHb (UFSCar), dedicated to the study of ecology and biodiversity of aquatic microorganisms, applying cutting edge methods and technologies such as the application of flow cytometry in the quantification of aquatic microorganisms and single-cell physiological properties, and massive next-generation sequencing techniques to explore the biodiversity of aquatic microorganisms, among others. The strategic goal is to crate a new research group and put it in the frontier of knowledge in this area of research, at the international level. (AU)
