阿拉斯加北部三个地区的空中节肢动物生物量和多样性模式

我们对阿拉斯加北部的三个地区进行了多年调查，其中两个位于阿拉斯加中部（费尔班克斯和特林），另一个位于阿拉斯加中南部（安克雷奇），我们记录了空中节肢动物生物量和多样性的模式。采样工作采用了树冠马拉色和近地传粉昆虫诱捕器，作为对一种急剧衰退的鸣禽进行平行研究的一部分。在夏季高峰期（6 月 15 日至 7 月 15 日），费尔班克斯诱捕器中的平均空中节肢动物生物量（50.6 mg-d-1，置信区间 [CI]：34.5-63.7）比安克雷奇（15.8 mg-d-1，CI：9.3-26.4）高出三倍多。特特林的数值居中（35.4 mg-d-1，置信区间[CI]：18.4-67.4）。温度与捕获的生物量呈正相关，而风力（1.5 m-s-1以上）与捕获的生物量呈负相关。为了获得物种级的多样性数据，我们重点研究了甲虫，它们代表了广泛的食性和类群。甲虫有 6229 个成年标本，364 个独特类群（大部分为种级类群）和 47 个科。甲虫的营养级分类在阿拉斯加中部的地点相似；两地都比安克雷奇有更大比例的食木甲虫。我们的研究首次揭示了阿拉斯加北方地区空中节肢动物生物量和多样性的地区差异和季节趋势，为未来建立了重要的基准。

期刊介绍： To publish papers of the highest scientific quality within the general area of insect (and other arthropods) conservation and diversity covering topics ranging from ecological theory to practical management. Papers are invited on the following topics: Conservation genetics; Extinction debt; Long-term conservation planning and implementation; Global implications of local or national conservation actions; Management responses of species and communities; Captive breeding programs; Comparisons of restored and natural habitats; Biogeography; Global biodiversity; Metapopulation dynamics; Climate change: impacts on distributions and range; Invasive species: impacts and control; Effects of pollution; Genetic threats to diversity by introgression; Effects of fragmentation on diversity and distribution; Impact of agricultural and forestry practices on biodiversity; Enhancing urban environments for diversity and protection; Biodiversity action plans: can we scale up from insects?; Effectiveness and choice of indicator species; Soil biodiversity and interactions with above-ground biodiversity; Ecological interactions at local levels; Ecological and evolutionary factors influencing diversity and local, regional and global scales; Sustainable livelihoods and training on the ground; Integrating science and policy.
