Long-term dynamics of metazoan parasites in an age- and size-structured host population.
PhD Dissertation, Faculty of Biosciences, Fisheries and Economics, The Arctic University of Norway, Universitetet i Tromsø
The present thesis addresses long-term dynamics in the parasite infections of Arctic charr, Salvelinus alpinus, and attempts to identify key ecological drivers explaining temporal variations and distributional patterns revealed for three parasite taxa with contrasting life cycles. Metazoan parasites have life cycles that range from relatively simple and direct, involving a single host species, to complex life cycles with multiple obligate hosts. The three parasite taxa represent the spectrum of life cycle complexity, from a direct life cycle with Arctic charr as the single host, to complex cycles with a multitude of hosts at each developmental stage of the parasite (Figure 1). Whereas each paper deals with a specific host-parasite association, the goal of this synopsis is to integrate the findings from the three papers and point to commonalities and differences across my results. I begin by introducing some aspects of parasite population ecology.
