Thesis Abstract

**Abstract
** The gut microbiota plays a crucial role in the health and behavior of marine mammals, yet its specific impact remains underexplored. This thesis investigates the intricate relationship between gut microbiota composition and the overall well-being of marine mammals. The study begins with a comprehensive literature review that highlights the current understanding of gut microbiota in various animal species, emphasizing the limited knowledge regarding marine mammals. Through the analysis of existing research, this thesis aims to bridge the gap in knowledge and provide novel insights into the significance of gut microbiota in marine mammal health. Methodologically, this research employs a combination of field observations, sample collection, and laboratory analysis to assess the gut microbiota diversity and composition in different marine mammal species. By comparing samples from wild populations with those in captivity, the study aims to elucidate the impact of environment and diet on gut microbiota composition. The findings reveal a diverse range of gut microbiota in marine mammals, with variations observed between species and environmental conditions. Through statistical analysis and data interpretation, this thesis identifies key microbial taxa associated with specific health outcomes and behavioral patterns in marine mammals. The discussion section delves into the implications of the research findings, highlighting the potential applications for conservation efforts, captive animal management, and ecosystem health. By elucidating the role of gut microbiota in marine mammal health and behavior, this study contributes valuable insights to the field of zoology and wildlife conservation. In conclusion, the research underscores the importance of understanding the complex interplay between gut microbiota and marine mammal well-being. By shedding light on this intricate relationship, the thesis advocates for further research and conservation initiatives aimed at preserving the health and behavior of these iconic marine species.

Thesis Overview

The project titled "The role of gut microbiota in the health and behavior of marine mammals" aims to investigate the intricate relationship between gut microbiota and the overall well-being and behavior of marine mammals. In recent years, there has been a growing interest in understanding the importance of gut microbiota in various animal species, including marine mammals, due to its significant impact on host health and physiology. Marine mammals, such as whales, dolphins, and seals, inhabit diverse marine environments and are known to have complex digestive systems that play a crucial role in their overall health. The gut microbiota, which consists of a diverse community of microorganisms residing in the gastrointestinal tract, has been shown to influence various physiological processes, including digestion, immune function, and metabolism. However, the specific role of gut microbiota in marine mammals and its relationship to their health and behavior remain largely unexplored. This research project will involve a comprehensive investigation into the gut microbiota composition of different species of marine mammals and its correlation with their health status and behavioral patterns. By employing advanced molecular techniques, such as next-generation sequencing, the project aims to identify the specific microbial communities present in the gut of marine mammals and analyze their potential functions and interactions with the host. Furthermore, the project will explore how changes in the gut microbiota composition may be linked to the occurrence of certain health conditions or behavioral abnormalities in marine mammals. By examining samples from both healthy and diseased individuals, the study seeks to elucidate the role of gut microbiota in maintaining homeostasis and preventing disease in these animals. Overall, this research will contribute to a better understanding of the significance of gut microbiota in marine mammals and provide valuable insights into the factors influencing their health and behavior. The findings of this study could have implications for the conservation and management of marine mammal populations, as well as for the development of potential therapeutic strategies targeting the gut microbiota to improve the health and welfare of these fascinating animals.
