Project Abstract

Evolutionary Dynamics of Host-Parasite Interactions in Diverse Ecosystems This project aims to investigate the complex and dynamic relationships between hosts and their parasites across various ecosystems, with the ultimate goal of advancing our understanding of the evolutionary processes that shape these intricate interactions. The study of host-parasite relationships is crucial in ecology, as these interactions play a fundamental role in shaping the structure and function of diverse communities, while also having significant implications for human and animal health. Parasites, which can range from viruses and bacteria to larger organisms like worms and arthropods, have a profound impact on their host species. They can influence host fitness, population dynamics, and even the evolution of host traits. Conversely, hosts have evolved a variety of defense mechanisms to cope with and resist parasitic infections. This co-evolutionary arms race between hosts and parasites is a key driver of biodiversity and ecosystem resilience. By examining the evolutionary dynamics of host-parasite interactions across different ecosystems, this project aims to shed light on the complex interplay between biotic and abiotic factors that influence these relationships. The research will focus on several key objectives 1. Identifying patterns of host-parasite co-evolution The project will explore the mechanisms by which hosts and parasites adapt to one another over time, examining the selection pressures and genetic changes that shape these co-evolutionary trajectories. 2. Assessing the impact of environmental heterogeneity The study will investigate how factors such as climate, habitat disturbance, and resource availability affect the dynamics of host-parasite interactions, and how these environmental variables influence the evolutionary trajectories of the interacting species. 3. Exploring the role of biodiversity in host-parasite systems The project will analyze how the diversity of host and parasite species within an ecosystem influences the stability and resilience of these interactions, and how changes in biodiversity may impact the evolutionary dynamics of host-parasite relationships. 4. Developing predictive models of host-parasite coevolution By integrating empirical data and theoretical frameworks, the research team will work to create models that can better predict the long-term outcomes of host-parasite interactions, with potential applications in disease management and conservation biology. To achieve these objectives, the project will employ a multi-disciplinary approach, combining field-based observations, laboratory experiments, and computational modeling. The research team will collect data on host and parasite diversity, population dynamics, and trait evolution across a range of ecosystems, from tropical rainforests to temperate grasslands. By integrating this empirical evidence with cutting-edge theoretical approaches, the project will advance our understanding of the complex and dynamic nature of host-parasite interactions, with far-reaching implications for the management and conservation of diverse ecosystems. The findings from this project will contribute to the broader scientific understanding of evolutionary ecology, host-parasite coevolution, and the role of biodiversity in maintaining ecosystem stability. The insights gained may also inform the development of more effective strategies for managing infectious diseases, both in human and animal populations, and aid in the conservation of threatened species and habitats. Overall, this project represents a significant step forward in unraveling the intricate web of life that connects hosts and their parasites across the Earth's diverse ecosystems.
