Abstract

Abstract. Northern Mockingbirds (Mimus polyglottus) were studied between 1995 and 2015 on a university campus in New Orleans, U.S.A., spanning the 2005 landfall of Hurricane Katrina. The storm subjected the city to high winds and a prolonged flood. Nesting success showed a spike for 3 y after the storm, after which it gradually sank back to near pre-storm levels. Number of broods detected jumped from the first to the second year after the storm on campus and at two nearby residential sites. Success of males in acquiring mates improved from the first nesting season after the storm to the second across the three sites. Results draw attention to the importance of considering top-down effects in analyzing the recovery of storm-impacted birds.

卡特里娜飓风前后美国新奥尔良北方知更鸟种群的人口动态

摘要1995年至2015年，在美国新奥尔良的一所大学校园里对北方知更鸟（Mimus polygottus）进行了研究，研究时间跨度为2005年卡特里娜飓风登陆。风暴使这座城市遭受大风和长时间的洪水袭击。风暴过后3天，筑巢成功率出现峰值，之后逐渐回落至风暴前的水平。风暴发生后的第一年到第二年，在校园和附近的两个住宅区检测到的窝数激增。从风暴后的第一个筑巢季节到三个地点的第二个筑巢季节，雄性获得配偶的成功率有所提高。研究结果提请注意在分析受风暴影响的鸟类恢复时考虑自上而下影响的重要性。

期刊介绍： The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist have broadened and its geographic coverage now includes North America with occasional articles from other continents. The old image of naturalist has changed and the journal publishes what Charles Elton aptly termed "scientific natural history" including field and experimental biology. Its significance and breadth of coverage are evident in that the American Midland Naturalist is among the most frequently cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.
