Abstract
Climate change has been reported to significantly threaten the survival of aquatic organisms with severe impacts on species distribution. However, species are not equal in the face of climate change. Differences in tolerances to abiotic factors may lead to niche differentiation of sympatric species, a potential mechanism for their coexistence. Microbial organisms associated to macroorganisms, so-called microbiome, could contribute to physiological acclimatation of the host and play an important role in the fitness of the latter. Four cryptic species of the free-living nematode complex Litoditis marina are often found to coexist locally. This co-occurrence shows abundances which vary with abiotic factors that have an impact on different life history traits. Knowledge of the effects of climate change on life history traits and the microbiome may help predict distribution of species and how they will cope with changing climate conditions. In this study, the impact of increased temperature on the microbiome and the life history traits of the cryptic species complex of L. marina was investigated using an experimental microcosm setup with controlled temperature treatments and high-throughput sequencing for metagenetic analysis of the nematode microbiome. Results showed that each of the four cryptic species have a specific microbiome and that the composition of the latter is influenced by both temperature and food availability in a species-specific way. The fact that the microbiome composition differed between cryptic species and between temperatures was reflected in their life history traits. The microbiome differed between and within species for almost all treatments, indicating that L. marina cryptic species have a specific microbiome which may help explain why they differ in their abiotic tolerances and are able to coexist.
