| contents | Evidence for latitude-driven changes in diel rhythms in a wide-ranging seabird. Gillies, Natasha Descamps, Sebastien Huffeldt, Nicholas Per McKendrick, Frederick Anker-Nilssen, Tycho Bogdanova, Maria Sandøy Bråthen, Vegard Chastel, Olivier Christensen-Dalsgaard, Signe Daunt, Francis Dehnhard, Nina Ezhov, Aleksey Fayet, Annette L Frederiksen, Morten Gavrilo, Maria Hedd, April Kolbeinsson, Yann Krasnov, Yuri V Labansen, Aili Linnebjerg, Jannie Lorentsen, Svein-Håkon Merkel, Flemming Moe, Børge Newell, Mark Newton, Stephen Olsen, Bergur Reiertsen, Tone Robertson, Gregory J Strøm, Hallvard Þórarinsson, Þorkell Lindberg Patrick, Samantha C Animals Circadian Rhythm Photoperiod Charadriiformes Diel rhythms synchronized to Earth's photic cycle are near-ubiquitous among animals living in regions with distinct day-night cues. Where such cues are reduced or absent, however, activity patterns may weaken, reorganize or become decoupled from the light-dark cycle, which may allow for more flexible behavioural expression. Using a dataset of >900 free-ranging black-legged kittiwakes from colonies spanning a broad latitudinal gradient (40-81°N), we show considerable population-level variation in diel activity patterns, from clear 24 h rhythms with distinct peaks at dawn and dusk at lower latitudes, to variable and non-diel rhythms with flattened activity patterns across the 24 h day at high latitudes. These patterns were consistent with the wide spectrum of light-dark cycles experienced across their breeding range, supported by our finding that activity was strongly predicted by sun elevation, suggesting alignment with the light-dark cycle. Together, our findings reveal substantial within-species variation in rhythmicity across latitudes and demonstrate that changes in the photic environment can reshape the temporal organization of activity even within a single, widely distributed species. |
