This five-year project seeks to characterize decadal scale changes in penguin and seabird populations on the Antarctic Peninsula, and to identify the factors driving these long-term changes. Two interconnected research activities are proposed: 1. Continued, long-term monitoring and censusing of penguin and seabird populations at 117 sites throughout the Antarctic Peninsula via opportunistic ship-based data collection. 2. Synthesis and quantitative analyses of datasets detailing long-term changes in five penguin and seabird species from diverse sites throughout the Antarctic Peninsula. When complete, the penguin/seabird database will incorporate data from the Antarctic Site Inventory (ASI), the CCAMLR database, the US AMLR database, the LTER database from Palmer Station, data from British and Argentine researchers, historic census data compiled by the Scientific Committee on Antarctic Research (SCAR), and, when possible, additional privately held datasets. Additional data for temperature change, sea ice coverage, the seasonal timing and intensity of human visitation, and other factors have been gathered and will be analyzed together with population trajectories within a spatially explicit framework. The research will include hierarchical statistical analyses to characterize the long-term population dynamics of several key polar species across multiple spatial scales (sites, regions, and the Peninsula). Analyses also will focus on specific subsets of the overall database to contrast visitor impacts on paired colonies, sites, and regions that share similar environmental conditions but differ in the intensity of tourism. The Broader Impacts include (1) research training and first-time Antarctic experiences for a postdoctoral researcher and several graduate students, all of whom will then be better positioned to bring their expertise in spatial and/or quantitative/theoretical ecology to bear on questions in polar research; (2) assembly and analysis of a large, multi-season database of penguin and seabird time series from the Antarctic Peninsula that will be publicly available, (3) assistance in distinguishing the impacts of tourism versus climate change on seabird populations. Under the Environmental Protocol to the Antarctic Treaty, Treaty Parties are charged with regular and effective monitoring to assess the impacts of human activities. This project will uniquely assist Parties in fulfilling this mandate.

这个为期五年的项目旨在表征南极半岛企鹅和海鸟种群的际阶段变化，并确定推动这些长期变化的因素。 提出了两项​​相互联系的研究活动：1。通过基于机会性船舶的数据收集，在整个南极半岛的117个地点，企鹅和海鸟种群的持续，长期监测和普查。 2。对数据集的合成和定量分析，详细介绍了整个南极半岛各种地点的五种企鹅和海鸟物种的长期变化。完成后，企鹅/海鸟数据库将合并来自南极现场库存（ASI），CCAMLR数据库，美国AMLR数据库，来自帕尔默站的数据库，英国和阿根廷研究人员的数据库，来自英国和阿根廷研究人员的数据库，历史悠久的人口普查数据，由科学委员会在Natarctic Research（sarce carterication in Difatentate in of Fipertates）以及其他可能的私有化（以及可能的私有化）中，以及其他可能的数据。温度变化，海冰覆盖率，人类探视的季节性时间和强度以及其他因素的其他数据已收集，将与空间显式框架内的种群轨迹一起进行分析。该研究将包括分层统计分析，以表征多个空间尺度（地点，区域和半岛）的几种关键极性物种的长期种群动态。分析还将重点关注整体数据库的特定子集，以对比访客对具有相似环境条件但旅游强度有所不同的配对菌落，地点和地区的影响。更广泛的影响包括（1）研究培训和初次对博士后研究人员和几位研究生的首次南极经验，然后所有这些都将更好地将其在空间和/或定量/理论生态学方面带来他们的专业知识，以在极地研究的问题上解决问题； （2）对南极半岛的企鹅和海鸟时间序列的大型，多季节数据库的组装和分析，（3）有助于区分旅游业与气候变化对海鸟种群的影响。 在《南极条约》的环境方案下，条约当事各方被指控进行定期有效的监控，以评估人类活动的影响。该项目将独特地协助当事方履行这一任务。
