| Summary: | Adult survival is a key parameter affecting population trends, especially among long-lived species (Lebreton & Clobert 1991). Understanding sources and patterns of variation in adult survival is particularly important for assessing population dynamics and consequently man-aging populations (Perrins et al. 1993, Saether et al. 1996). Little is known about adult survival of most colonial seabirds in the high Arctic, at a time when Arctic environments are rapidly changing (ACIA 2005), and thus our ability to understand and predict the im-pacts of these environmental stressors on Arctic seabirds is compromised. This is especially true for Arctic specialist species, as climate change (i.e. rapid warming in Arctic regions) is likely to have dispropor-tionately profound negative effects on their long-term viability (McCarty 2001). Further, the logistical chal-lenges of working with cliff nesting species in high Arctic environments have resulted in disproportionately large knowledge gaps for species such as Thayer’s Gull Larus thayeri and Glaucous Gull L. hyperboreus, both considered among the least known of all North |
