MM012:
Functional, ecological, and evolutionary implications of microdiversity and intra-specific variability in aquatic microorganisms


Session ID#: 29912

Session Description:
Many aquatic microorganisms exist as diverse genetic clusters, rather than clone-like populations. However, the extent, ecological and evolutionary mechanisms, and implications of their genotypic and phenotypic variability remain unclear. In some instances, this microheterogeneity has been linked to differences in environmental distribution and functional attributes, resulting in ecotypes. We expect that intra-specific trait variability (phenotypic and genotypic) plays an important role in determining the outcome of inter-specific competition, and hence overall biodiversity. On one hand, intra-specific variability can cause niche overlapping, thereby reducing diversity, at least as systems approach steady state. On the other hand, intra-specific variability can also reduce fitness differences, thereby lengthening extinction timescales and sustaining diversity in dynamic environments. In general, however, it remains unclear how aquatic microorganisms diversify and evolve into genetically and ecologically different populations.

 

Recent advances in high throughput sequencing, informatics, metabolomics, and other means of community and single cell interrogation are being applied to investigate genetic variation, evolutionary events, and functional differentiation within sets of closely related microorganisms. Such studies will allow better understanding of the influence of microdiversity on the stability, resilience, biodiversity, and function of ecosystems. We invite submissions investigating the impact of microdiversity on the ecology, evolution, and function of populations of microorganisms in aquatic systems using any approach, including theoretical analysis, numerical modeling, observational and experimental studies.
