摘要

摘要:美国热带太平洋(USTP)是全球重要的海鸟栖息地,有32种数千万只海鸟在此繁殖。在USTP繁殖海鸟面临的两个最大威胁是全球气候变化造成的栖息地淹没和非本地捕食者。我们评估了USTP海鸟物种的繁殖状况,以及哪些物种将从恢复活动中获益最多。我们对每个物种的灭绝风险、对气候变化和入侵掠食者的脆弱性进行了9项评分,然后将所有标准的得分相加得到总分,并根据总体保护需求对物种进行排名。排名前五的濒危物种依次是夏威夷海燕(Pterodroma tanhensis)、纽埃尔海鸥(Puffinus newelli)、波利尼西亚风暴海燕(Nesofregetta fuliginosa)、凤凰海燕(Pterodroma alba)和黑脚信天翁(phoebastia nigripes)。我们还评估了USTP中的86个地点作为海鸟的潜在来源和恢复地点,以减轻海平面上升和入侵掠食者的影响。在USTP中排名前五的物种中,有三种正在进行一些恢复行动,但需要采取更多的行动。两种顶级物种(波利尼西亚风暴海燕和凤凰海燕)主要出现在USTP之外。需要在USTP内采取行动,以补充太平洋其他地方正在采取的现有保护措施,并应优先考虑未来的管理行动。

Prioritization of Restoration Needs for Seabirds in the U.S. Tropical Pacific Vulnerable to Climate Change
Abstract: The U.S. Tropical Pacific (USTP) is a globally important area for seabirds with tens of millions of individuals of 32 species breeding in the region. The two greatest threats to breeding seabirds in the USTP are inundation of colonies caused by global climate change and non-native predators. We assessed the status of seabird species breeding in the USTP and which species would benefit most from restoration activities. We scored each species for nine criteria that reflected their extinction risk and vulnerability to climate change and invasive predators, then summed the scores of all criteria to obtain an overall score and ranked the species in terms of overall conservation need. The top five species at risk (in order) were Hawaiian Petrel (Pterodroma sandwichensis), Newell's Shearwater (Puffinus newelli), Polynesian Storm-Petrel (Nesofregetta fuliginosa), Phoenix Petrel (Pterodroma alba), and Black-footed Albatross (Phoebastria nigripes). We also assessed 86 locations in the USTP as potential source and restoration sites for seabirds to mitigate the impacts of sea level rise and invasive predators. Some restoration actions are underway for three of the top five species in the USTP, but more actions are needed. Two of the top species (Polynesian Storm-petrel and Phoenix Petrel) occur primarily outside the USTP. Actions within the USTP are needed to complement existing conservation measures underway elsewhere in the Pacific and should be prioritized for future management actions.

期刊介绍: Pacific Science: A Quarterly Devoted to the Biological and Physical Sciences of the Pacific Region The official journal of the Pacific Science Association. Appearing quarterly since 1947, Pacific Science is an international, multidisciplinary journal reporting research on the biological and physical sciences of the Pacific basin. It focuses on biogeography, ecology, evolution, geology and volcanology, oceanography, paleontology, and systematics. In addition to publishing original research, the journal features review articles providing a synthesis of current knowledge.
