揭示适宜的微观和宏观生境特征，拯救极度濒危的智利有袋甲虫 Sclerostomulus nitidus (Coleoptera: Lucanidae)

腐木类昆虫对腐木的生存有特定的要求，如腐烂的后期。然而，在世界上的一些地方，朽木目前被认为是一种濒危资源。Poqui的鹿角甲虫(鞘翅目:鹿角虫科)是一种极度濒危的生孢子虫，在2010年被重新发现，但目前非学术收集威胁着它在预计10年内的灭绝。我们的主要目的是通过将黑桫椤的丰度与植被类型(纯黑桫椤林分与亲湿林分)和海拔高度等枯木微生境变量联系起来，确定恢复该物种种群的关键宏观和微生境工具。我们测量了枯木的腐烂阶段(低、中、高)、枯木的体积和长度，以及枯木生长的植被类型和海拔高度，并利用GLM分析评估了这些变量作为枯木丰度的预测因子。我们发现丰度(当前和预测)与木材高腐烂阶段和低海拔高度密切相关(90%)。通过(i)替换低质量的高度腐烂的枯木，但保持相同的体积，(ii)作为一种新的野外试验，注入高度合适的栖息地来恢复微栖息地，可能是拯救牛耳草的最佳短期到中期替代方案。

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.
