通过迁移恢复衰退物种：在城市环境中利用不会飞的蚱蜢进行试验

种群易位越来越多地被用作脊椎动物的保护策略。然而，尽管无脊椎动物对食物网有潜在的好处，尽管在空间有限的小区域(包括城市环境)进行这种转移是可行的，但对无脊椎动物进行转移的尝试相对较少。我们在墨尔本市区对1851只无飞行能力的蚱蜢进行了36次易位，其中93%的原始栖息地已经丧失。本研究旨在了解蝗虫持续存在的基本特征，并研究其在整个活跃期的发现、占据、扩散和生境适宜性，以提高城市环境中利用植被恢复地和小残余生境的昆虫易位成功率。我们还在短期试验中测量了一周后的运动和检测概率。为期一周的试验表明，蚱蜢的性别和颜色变化不影响检测的概率，也没有证据表明雌性和雄性的定向运动。易位后1年，36个易位中有28个易位中发现了紫腹弧菌。这些调查结果表明，在不同的调查季节，检测概率会发生变化，并受土壤温度的影响。此外，土壤温度对冬季调查的检测也有正向影响。禾本科植被覆盖、植物物种丰富度和杂草覆盖对占用率有影响。我们没有发现雌性和雄性在F1代中定向运动的证据。丰度和存在/缺失数据最好的解释是禾草类覆盖和植物物种丰富度。我们的研究结果表明，无翅蚱蜢在适合栖息地的小块城市斑块中迁移是可行的，有助于恢复无脊椎动物的生物多样性和生态服务。

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.
