现有的花偏好指标在授粉者的最佳植物上存在分歧:该选择哪个指标?
在为传粉昆虫保护而种植花朵时,确定种植什么花朵是一项挑战,因为花朵的建立可能耗时且资源密集。为了缓解这一挑战,研究人员提出了从植物-传粉昆虫相互作用数据中数学确定传粉昆虫更喜欢哪种花朵的方法,其可以被定义为当与其他花卉物种平等提供时,授粉者将选择一个花卉物种的可能性。我们比较了从同一数据集计算的五个合理的、同行评审的偏好指标产生的花列表,并研究了每个指标如何控制花的丰度以及与传粉昆虫访问次数的关系。我们发现,每个偏好指标返回的排名花列表之间几乎没有相关性,而且这些指标在控制丰度和提供不同信息的程度上与访问次数不同。计算出的花朵偏好列表之间的不一致部分是由于每个指标控制丰度的方式不同,这表明这些偏好指标需要进行实证检验,需要对影响传粉昆虫花朵偏好的因素进行更多的研究。我们不鼓励使用三种偏好指标(置信区间、资源使用和大规模行动假设指标),警告不要使用一种(中心性指标),并建议使用偏好指数指标,因为它对采样不足不敏感,易于使用,而且与传粉昆虫访问次数无关。

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.
