SGER: Effects of B15 on Breeding Success of the Cape Crozier Emperor Penguin Colony

0224957 Ponganis这个项目将调查冰山B-15对克罗齐角帝企鹅数量的影响。这个帝企鹅殖民地最南端的种群，尽管有时波动很大，但在过去的年里一直在稳步增长，据统计有多达1200只雏鸟。这可能代表了2400-3000只鸟的成年种群。然而，在2001年，B-15在冬季繁殖期进入克罗齐角地区后，没有发现活的帝企鹅雏鸟，殖民地已经消失。该项目的目标是确定殖民地是否会在克罗齐角重新建立自己或搬迁到附近的不同地点。如果企鹅群在克罗齐角重新建立，我们将通过今年的企鹅数量统计来估计前一年的损失。2001年，殖民地被冰山摧毁，这是一次自然实验，旨在检验繁殖帝企鹅对短期灾难的适应能力。这项研究的更广泛影响与这个殖民地的历史重要性和全世界的兴趣有关，因为它是第一个发现的帝企鹅殖民地，可能是所有企鹅殖民地中最长的人口普查记录。

0224957PonganisThis project will investigate the effects of the iceberg, B-15, on the emperorpenguin population at Cape Crozier. The population of this southernmost of emperorpenguin colonies, although sometimes fluctuating radically, had steadily grown in pastyears, with as many as 1200 chicks counted. This probably represented an adultpopulation of 2400-3000 birds. However, in 2001, after B-15 ground into the CapeCrozier area during the winter breeding period, no live emperor chicks were found. Thecolony had disappeared. The goal of this project is to determine if the colony will re-establish itself at Cape Crozier or relocate nearby to a different site. If the colonyreestablishes at Cape Crozier, we will estimate the previous year's loss with a census ofthe chicks present this year. The destruction of the colony site by the iceberg in 2001represents a natural experiment to examine the resilience of breeding emperors to shortterm disasters. Broader impacts of this study are related to the historical importance andworldwide interest in this colony as it was the first emperor colony discovered, and hasprobably the longest census record of any penguin colony.
