| Summary: | Recognising importance of deviation from a population mean in an animal's behavior is not only necessary to understand the evolution and stability of the whole system but also to predict the future of a population in an altering environment. Arctic seabirds are expected to exhibit high synchronization in timing of breeding at the population level, due to highly seasonal and harsh environmental conditions. Nevertheless, even in such a highly synchronized system, there are always some earlier and later breeders, and what causes this inter-pair variation remains an intriguing question. Using a set of eight years of data on the dovekie (Alle alle), a small Arctic seabird, we examined potential drivers of the observed distribution of breeding phenology. We found that dovekie pairs were quite repeatable in their phenology, and preserved their phenological status, with their chicks hatching consistently before, during, or after the population median date for hatching, despite that calendar position of the median ... : Data were collected in the dovekie breeding colony in Hornsund (SW Spitsbergen, 77°00′ N, 15°33′ E). Collected data (eight study seasons) include: phenology of breeding pairs of known identity (hatching date) and growth rate of their chicks, pair characteristics (partners morphological similarity) and GPS coordinates focal pairs nest. To establish pairs phenology and chick growth rate focal nests were controlled every 2-4 days. To establish partners characteristics, focal individuals molecularly sexed and measured. Coordinates of focal nests were taken with a manual GPS. ... |
