Holistic View on Health Two Protective Layers of Biodiversity. Abstract The human intestine hosts a vast and complex microbial community that is vital for maintaining several functions related with host health. The processes that determine the gut microbiome composition are poorly understood, being the interaction between species, the external environment, and the relationship with the host the most feasible., However, much of our current interest is focused on the gut microbiota, its shaping by the host, its contributions to host immunity and aging, and its potential contributions to host evolution. Work in the Shapira lab spans the range between molecular mechanisms and population-level experimental evolution. To achieve this, research at the Shapira lab takes advantage of the nematode.

Abstract The human intestine hosts a vast and complex microbial community that is vital for maintaining several functions related with host health. The processes that determine the gut microbiome composition are poorly understood, being the interaction between species, the external environment, and the relationship with the host the most feasible. The gut microbiome (the collection of microbial genomes) offers increased genetic variation compared with the host genome, faster evolution, and the ability to exchange microbes (and their genes and associated functions) with the environment, features that could contribute to host adaptation.

Drawing on the structure of bacterial genomes, this model distinguishes between a host-adapted Although the cause for a potential disruption of this symbiosis is unclear, it infects up to 60% of all arthropod species, including endemic Hawaiian insect lineages (e.g., Nesophrosyne and Drosophila) and is known to have parasitic or mutualistic interactions with its hosts [75,76,77,78,79]. Whole-body surveys of insect microbiomes provide an opportunity to screen for non-gut associated

genome evolution that will be necessary to understand the lab and the rest of the class content on microbial symbiosis. The reading assignments will review papers in the area Abstract. Symbioses are ubiquitous and have played an influential role in the evolution of life on Earth. Genomic studies are now revealing a huge diversity of associations among hosts and their microbiotas, allowing us to characterize their complex ecological and evolutionary dynamics.
