巴尔米拉环礁位于赤道太平洋的莱恩群岛上，是热带太平洋上现存最大的大皮索尼亚森林之一。2003年，我们对陆地节肢动物进行了调查，记录了现存的本地物种和引进物种的丰富度，并与历史记录进行了比较，评估了对本地物种和生态系统完整性的潜在威胁。共收集到节肢动物类群115个，使自1913年以来记录的类群总数达到162个。本地种很少；大多数分类群都是从夏威夷群岛偶然引入的，夏威夷群岛被认为是巴尔米拉引入的主要来源。与一九一三年及一九四八年的历史统计调查的重叠程度较低(
Palmyra Atoll, in the Line Islands of the equatorial Pacific, supports one of the largest remaining native stands of Pisonia grandis forest in the tropical Pacific Ocean. In 2003, we surveyed terrestrial arthropods to document extant native and introduced species richness, compare these lists with historical records, and assess potential threats to native species and ecosystem integrity. In total, 115 arthropod taxa were collected, bringing the total number of taxa recorded since 1913 to 162. Few native species were collected; most taxa were accidental introductions also recorded from the Hawaiian Islands, the presumed main source of introductions to Palmyra. The overlap with previous historical Surveys in 1913 and 1948 was low (
