Terrestrial arthropods of Steel Creek, Buffalo National River, Arkansas. I. Select beetles (Coleoptera: Buprestidae, Carabidae, Cerambycidae, Curculionoidea excluding Scolytinae)
收藏资源简介：
Background: The Ozark Mountains are a region with high endemism and biodiversity, yet few invertebrate inventories have been made and few sites extensively studied. We surveyed a site near Steel Creek Campground, along the Buffalo National River in Arkansas, using twelve trap types â Malaise traps, canopy traps (upper and lower collector), Lindgren multifunnel traps (black, green, and purple), pan traps (blue, purple, red, white, and yellow), and pitfall traps â and Berlese-Tullgren extraction for eight and half months. New information: We provide collection records of beetle species belonging to eight families collected at the site. Thirty one species represent new state records: (Buprestidae) Actenodes acornis, Agrilus cephalicus, Agrilus ohioensis, Agrilus paracelti, Taphrocerus nicolayi; (Carabidae) Agonum punctiforme, Synuchus impunctatus; (Curculionidae) Acalles clavatus, Acalles minutissimus, Acoptus suturalis, Anthonomus juniperinus, Anametis granulata, Idiostethus subcalvus, ...
背景：奥扎克山脉（Ozark Mountains）是一个特有性与生物多样性均极高的区域，但目前针对该区域的无脊椎动物区系调查极少，且鲜有点位得到深入研究。本次研究对阿肯色州布法罗国家河沿岸钢溪营地（Steel Creek Campground）附近的一处调查点位开展了为期八个半月的采样工作，调查期间共使用12类诱捕器材——包括马来氏诱捕器（Malaise traps）、冠层诱捕器（含上层与下层收集器）、林德格伦多漏斗诱捕器（Lindgren multifunnel traps，黑色、绿色、紫色三种）、盘式诱捕器（pan traps，涵盖蓝、紫、红、白、黄五色）以及陷阱诱捕器（pitfall traps）——并采用Berlese-Tullgren萃取法进行样本处理。 新发现：本研究收录了该调查点位采集到的隶属于8个科的甲虫物种的采集记录，其中31个物种为该州的新纪录物种：（吉丁甲科Buprestidae）Actenodes acornis、Agrilus cephalicus、Agrilus ohioensis、Agrilus paracelti、Taphrocerus nicolayi；（步甲科Carabidae）Agonum punctiforme、Synuchus impunctatus；（象甲科Curculionidae）Acalles clavatus、Acalles minutissimus、Acoptus suturalis、Anthonomus juniperinus、Anametis granulata、Idiostethus subcalvus……
