ABSTRACT Carabidae (Coleoptera) are commonly used as indicators of ecosystem health due to their high diversity, conservation value and relative ease of identification. Carabids were monitored at Ahuriri Scenic Reserve, Port Hills, Canterbury, from August 2007 to September 2008 using pitfall traps. Carabid captures, species richness and distribution across the reserve were compared with those found in a similar study in 1977–1978. Monthly carabid captures were highly correlated with average temperature in both studies. There was little evidence of carabids responding to habitat factors, such as leaf litter depth, pH or ground cover. However, Megadromus antarcticus was positively associated with canopy openness and ground cover, whereas Holcaspis angustula was more abundant where canopy cover was extensive and there was a relatively high incidence of bare rock. Thirteen species of carabid were recorded in 1977–1978, of which six were absent, four had decreased, one was stable and two species increased in abundance from collections made in 2007–2008. The loss of one Banks Peninsula and five New Zealand endemic beetle species from this reserve is of concern, and future work should aim to gain more detailed information on the habitat requirements of these species to assist conservation management strategies.

对班克斯半岛 Ahuriri Scenic Reserve 的地面甲虫（鞘翅目：Carabidae）进行的调查，以及与 30 年前进行的先前调查的比较

摘要 Carabidae（鞘翅目）因其高度的多样性、保护价值和相对容易识别而常被用作生态系统健康的指标。2007 年 8 月至 2008 年 9 月，在坎特伯雷港山的 Ahuriri Scenic Reserve 使用陷阱陷阱对 Carabids 进行了监测。保护区内的甲虫捕获量、物种丰富度和分布与 1977-1978 年类似研究中发现的情况进行了比较。在这两项研究中，每月的carabid 捕获与平均温度高度相关。几乎没有证据表明carabids对栖息地因素有反应，例如落叶深度、pH值或地面覆盖物。然而，Megadromus antarcticus 与冠层开放度和地面覆盖呈正相关，而 Holcaspis angustula 在树冠覆盖广泛且裸岩发生率相对较高的地方更为丰富。1977-1978 年记录了 13 种carabid，其中 6 种缺失，4 种减少，1 种稳定，2 种增加了 2007-2008 年收集的数量。该保护区丧失了一种班克斯半岛和五种新西兰地方性甲虫物种令人担忧，未来的工作应旨在获得有关这些物种栖息地要求的更详细信息，以协助保护管理战略。
