Galling昆虫群落介导火灾对其相关寄生蜂群落的影响

了解火灾对多营养级的影响对于火灾状况和气候变化至关重要。与食草动物相比，营养水平较高的昆虫，如寄生蜂，更容易受到栖息地变化的影响，因为它们需要建立良好的宿主种群才能生存。目前，火灾对寄生蜂的影响及其与宿主的相互作用尚不清楚。我们的目的是研究在不同火灾场景下，寄生蜂和鸡食昆虫系统的丰度、丰富度和物种组成的变化，以及食物网结构。我们询问了寄生蜂群落的丰度、物种丰富度和组成的潜在变化是否可以用带毛植物的丰度、带毛昆虫的物种丰富度和构成来解释，以及火灾如何影响带毛昆虫-寄生蜂食物网的结构。寄生蜂丰富度最高的是9 火灾发生后数年，而寄生蜂的丰度不受火灾影响。9种寄生蜂的种类组成火灾发生后数年的情况与未燃烧和3年的情况不同火灾发生后数年。寄生蜂群落受寄主植物丰度、物种丰富度和寄主昆虫群落组成的调节。脆弱性在9 火灾发生后数年，但随着网络规模的增加而增加。火灾通过寄生蜂群落的变化影响寄生蜂群落。火灾场景的排他性、寄生蜂物种的饮食专门性和令人恼火的昆虫丰富度的差异可能解释了所发现的模式。我们的研究支持了这样的证据，即火灾在形成寄生蜂群落的宿主的可用性方面造成了栖息地的异质性，在食物网中具有自下而上的影响。此外，在被烧毁的地区，记录到了独特的昆虫-寄生蜂相互作用。

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.
