加利福尼亚州内华达山脉高地森林和草甸火灾后花卉的丰富性推动了传粉昆虫的多样性

在美国西部的干燥森林中，授粉昆虫提供了重要的生态系统服务，它们依赖于频繁的中低强度火灾所创造或维持的开阔栖息地。我们在加利福尼亚内华达山脉的局部（即地块尺度）和区域（燃烧严重程度等级）空间尺度上研究了燃烧严重程度对高地森林和草甸栖息地授粉昆虫多样性的影响、在草地上，传粉昆虫的丰富度随着火灾严重程度的增加而下降，但在高地，火灾严重程度对传粉昆虫的丰富度没有显著影响。在区域尺度上，我们发现两种栖息地中不同燃烧等级的α相似，尽管与未燃烧的高地相比，燃烧过的高地群落往往不那么均匀。中度燃烧的高地栖息地的 β 明显高于未燃烧的高地栖息地，但草甸栖息地的 β 没有明显差异。由于草甸往往比高地更具多样性，对高烧的负面影响也更敏感，因此针对传粉昆虫的保护措施可以优先考虑清除可能会增加这些系统火灾严重性的侵占性针叶树种。

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.
