Project Abstract

This project aims to conduct a comprehensive investigation into the gut microbiome composition and diversity of herbivorous and carnivorous mammals. The gut microbiome, the complex community of microorganisms residing within the gastrointestinal tract, plays a crucial role in the overall health and well-being of the host organism. Understanding the differences in gut microbiome between these two dietary groups can provide valuable insights into the evolutionary adaptations, physiological functions, and potential implications for animal and human health. Herbivorous and carnivorous mammals have evolved distinct digestive strategies to extract the necessary nutrients from their respective diets. Herbivores primarily consume plant-based materials, which are rich in complex carbohydrates and fiber, while carnivores rely on animal-derived proteins and fats. These dietary differences are expected to shape the gut microbiome, as the microbial communities must adapt to the available substrates and metabolic requirements of the host. By conducting a comparative analysis of the gut microbiome in herbivorous and carnivorous mammals, this project aims to uncover the underlying mechanisms that govern the assembly and maintenance of these microbial communities. The research will involve the collection of fecal samples from a diverse range of herbivorous and carnivorous mammalian species, representing different evolutionary lineages and habitats. Using state-of-the-art metagenomic sequencing techniques, the project will analyze the taxonomic composition, functional capabilities, and overall diversity of the gut microbiome in these two dietary groups. The findings from this project will contribute to the broader understanding of the co-evolution between hosts and their gut microbiomes. Herbivorous mammals, with their reliance on plant-based materials, are expected to harbor a more diverse and enriched gut microbiome, capable of efficiently breaking down complex carbohydrates and extracting essential nutrients. In contrast, carnivorous mammals may possess a relatively less diverse gut microbiome, but with specialized functions tailored to the digestion of animal-derived proteins and fats. Furthermore, this project will explore the potential implications of these dietary-driven differences in gut microbiome composition on the host's physiology, immune function, and susceptibility to various diseases. Comparative analyses may reveal unique microbial signatures or metabolic pathways associated with herbivorous or carnivorous diets, which could inform our understanding of dietary-related health conditions in both animals and humans. The data generated from this project will be valuable for the scientific community, providing a comprehensive reference dataset for the gut microbiome of herbivorous and carnivorous mammals. This information can serve as a foundation for future studies investigating the role of the gut microbiome in animal health, evolutionary adaptations, and potential applications in areas such as conservation biology, veterinary medicine, and human nutrition. Overall, this project represents a significant step forward in unraveling the complex relationships between diet, gut microbiome, and host physiology, with the potential to contribute to the advancement of our understanding of the fundamental principles governing host-microbiome interactions in mammals.
