Biology, Ghent University2Royal Belgian Institute of Natural Sciences nele.demeester@ugent.be- The microbiome differs between species- Food conditions alter the microbiome of the species- Interspecific interactions change the microbiome of the species Niche differentiation may be an important mechanism for coexistence of cryptic speciesINTRODUCTION -Behind the morphological similarity of many species hides a substantial cryptic genetic diversity -Coexistence of cryptic species challenges competition theory because fierce competition is expected between highly similar species- Coexistence can be achieved by ecological differences (i.e. resource differentiation) between cryptic species??? Are there differences in microbiomes and feeding strategies???MATERIAL & METHODS-Cryptic species of marine nematode Litoditis marina: Pm1; Pm3 and Pm4-Ten individuals subjected toA) interspecific competition (food = a ‘natural’ bacterial mix)B) different feeding conditions:starved, Escherichia coli suspension and a ‘natural’ bacterial mix- 16S rRNA Next Generation Sequencing (Illumina MiSeq)to characterize the microbiomes of individual nematodesRESULTSCONCLUSIONSE.coli suspensionBacterial mix
