Biogeochemical cycles are networks of processes with global impacts. Despite their large-scale influence, the majority of the crucial processes occur at the microscale and are conducted by microorganisms. It is at this scale where communication and chemotaxis responses in the microbial world take place by the exchange of chemical signals, also named infochemicals. Within the extensive range of signals, the role of dimethylated sulfur compounds (DMSCs) is noteworthy and controversial, especially in the framework of predator-prey interactions. Our research combines the following three topics: (i) Chemotactic behavior of herbivore protists; (ii) the role of dimethylated sulfur compounds (DMSCs) as infochemicals, and (iii) microzooplankton selective predation. The research project hypothesizes an attractant role of DMSP and DMS for heterotrophic protists. In order to explore this premise three potential chemotactic cues (DMSP, DMS and acrylate) are tested against four species of microzooplankton protists (Oxyrrhis marina, Gyrodinium dominans, Strombidium arenicola and Karlodinium armiger), combining a traditional microcapillary assay coupled with real-time visualization tools and a detailed image analysis. The study provides clear evidence of positive chemotaxis towards DMSP suggesting a clear influence in the swimming behavior of some of the protists tested. Supplementary radioisotope incubations provided hints about the possible usage of this compound by each protist. Additionally, an unexpected chemoattractant role of acrylate was detected in some experiments. Predator-prey interactions shape trophic web dynamics and thus the main fluxes of organic matter. Besides, the fate and transformation of DMSCs has a relevant impact on the biogeochemical sulfur cycle and the oceanic emission of atmospheric sulfur. Therefore, by studying microscale communication and its consequences we can contribute to the investigation of large-scale questions. 2023-05-29T11:30:02Z 2023-05-29T11:30:02Z 2022-05-29 2023-05-29T11:30:02Z comunicación de congreso Marine Microbes: Gordon Research Conference (2022) http://hdl.handle.net/10261/309895 Sí none
