Time-series covering 23 years for a long-lived seabird, the Atlantic puffin (Fratercula arctica L.) at Røst, northern Norway, was used to explore any indirect effects of climatic variations on chick production. By fitting statistical models on the duration of the nestling period, we found that it may be estimated using the average sea temperature and salinity at 0-20 m depth in March (having a positive and a negative effect, respectively). We propose that when the phytoplankton bloom occurs in early spring, adverse oceanographic conditions, i.e. low temperature and high salinity in March, have a negative effect on puffin reproduction by degradation of the prey availability (mainly Clupea harengus) for chick-feeding adults three months later.
对挪威北部罗斯特岛的长寿海鸟大西洋海鹦（Fratercula arctica L.）长达23年的时间序列进行了研究，以探索气候变化对雏鸟繁殖的任何间接影响。通过对育雏期持续时间拟合统计模型，我们发现可以使用3月份0 - 20米深度处的平均海水温度和盐度来估计育雏期（分别具有正向和负向影响）。我们提出，当早春出现浮游植物大量繁殖时，不利的海洋学条件，即3月份的低温和高盐度，会通过降低三个月后用于喂养雏鸟的成年海鹦的猎物可获得性（主要是鲱鱼），对海鹦繁殖产生负面影响。
