Boulinier, T. & McCoy, K.D. (2016). Host-parasite systems in polar areas as models to explore inter-specific dynamics in spatial contexts. – Oral communication at SFE meeting in Marseille, in the (ZATA) Symposium on 'Ecological impacts of climate change in Polar Regions'..
Abstract: Exploring how species interact in a spatial context is critical for understanding how they may respond to environmental changes. Because host-parasite systems in polar areas are relatively simple in terms of numbers of species involved (communities of a few hosts and parasites), because the distribution biodiversity is highly structured in space in polar areas (e.g., colonies of seabirds are hotspot of biodiversity), and because some of the effects of global change are especially rapid in polar areas, host-parasite systems in such areas can constitute unique models to investigate how particular ecological and evolutionary processes may affect the responses of communities to environmental changes at different scales. Using polar seabirds and their parasites as study systems, we illustrate how results of basic and applied relevance could be obtained on processes such as host race formation in arthropod vectors, host mediated dispersal and transgenerational immunity. Current work on seabird ticks in polar areas for instance shows that host specialization likely occurred repeatedly, with direct implications for the broad circulation of tick-borne agents such as Lyme disease bacteria Borrelia burgdorferi and flaviviruses. Detailed investigations about host and parasite dispersal in the same systems also stress that knowledge of key life history traits of the involved species is required to infer colonization rates and the history of spread of infectious agents. Polar areas thus not only constitute areas where dramatic changes may be occurring, but also where important insight can be gained about general processes involved in the responses of communities to environmental changes.

Abstract: The Arctic is facing major environmental changes impacting marine biodiversity and ecosystem functioning. One way of assessing the responses of an ecosystem to these changes is to quantitatively study food web dynamics. Here, we used stable isotope (δ15N and δ13C) analyses of 39 Arctic marine species to investigate trophic relationships and isotopic niches of the West Greenland food web in 2000–2004. The lowest δ15N values were found for suspension feeding blue mussel (Mytilus edulis; 6.1 ‰) and the highest for polar bear (Ursus maritimus; 20.2 ‰). For δ13C, copepods (Calanus spp.) had the lowest values (−20.4 ‰) and snow crab (Chionoecetes opilio) the highest values (−15.8 ‰). Our results show that the three trophic enrichment factor (TEF) approaches used to quantify species trophic positions (fixed TEF of 3.8 and 3.4 ‰ or scaled TEF) did not generally affect trophic modelling and provided similar conclusions. Overall, the findings in this study are in good agreement with previous investigations of other Arctic marine ecosystems. Interestingly, we found little overlap of core isotopic niches used by the four investigated functional groups (mammals, seabirds, fish and invertebrates), except for seabirds and fish where an overlap of 24 % was found. These results provide new insights into species and functional group interactions, as well as into the food web structure and ecosystem functioning of an important Arctic region that can be used as a template to guide future modelling of carbon, energy and contaminant flow in the region.
