Oneof the major advances achieved last decade was the discovery of marine photoheterotrophic bacteria, which challenged our view onmicrobial food webs in the ocean. These organisms are heterotrophs that rely mainly on organic matter but are capable of harvestinglight to supplement their energy requirements. In the last years, we have used various approaches to uncover the ecology of a groupof marine photoheterotrophs, the aerobic anoxygenic phototrophic bacteria (AAPs). In particular, we have combined infrared mi-croscopy, quantitative PCR and Illumina sequencing with large sampling initiatives (i.e., the Blanes Bay Microbial Observatory andthe Malaspina circumnavigation expedition) as well as with manipulation experiments to explore their diversity, seasonality, biogeog-raphy and, more importantly, their functional role in marine ecosystems. Our results confirm that the AAPs are widely distributed inthe global surface oceans and that the different phylogenetic groups present a certain degree of biogeography. Moreover, we havedemonstrated that these bacteria show a clear seasonality both in abundance and community structure. But foremost, we have foundthat the AAPs are fast-growing bacteria contributing significantly to the recycling of organic matter and that they can be stimulatedby light in the marine environment. The results of our ongoing work will be presented and discussed in detail at the conference Peer Reviewed 2019-10-09T08:04:55Z 2019-10-09T08:04:55Z 2019-02-07 2019-10-09T08:04:55Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 1st Iberian Ecological Society Meeting (2019) XIV Congreso Nacional de la Asociación Española de Ecología Terrestre (2019) http://hdl.handle.net/10261/192350 Sí none Sociedad Ibérica de Ecología
