在过去的十年里，越来越多的传粉者减少的证据引起了人们对陆地生态系统的功能和作物生产的可持续性的担忧。虽然土地利用变化已成为主要原因，但大多数野生传粉者与主要土地利用类型的亲缘关系仍不清楚。填补我们知识上的这一空白是改进养护和管理方案的先决条件。我们使用基于公民科学的全国范围监测计划(Spipoll)的数据，估计了花卉游客与城市、农业和自然土地利用的亲和力。我们测试了不同昆虫目和不同昆虫频率(频繁或不频繁)的亲和力是否不同。结果表明，昆虫目与三种土地利用类型的亲和力不同。除膜翅目昆虫对不同的土地利用表现出较强的耐受性外，所有访花者对城市地区表现出负亲和力，对农业和自然地区表现出正亲和力。此外，不常见的类群与城市地区的亲和力较低，与自然地区的亲和力较高。在常见的分类群中，膜翅目和鞘翅目包括三种土地利用类型的专家，而双翅目和鳞翅目包括除城市以外的所有地区的专家。我们的方法首次在广泛的分类学和广泛的地理范围内对花卉游客与主要土地利用类型的亲和力进行了标准化评估。我们的结果表明，对于花卉游客社区来说，最有害的土地利用变化是城市化。此外，我们的发现强调了这样一个事实，即农业区有潜力容纳高度多样化的传粉者群落。因此，我们建议政策制定者应把重点放在农地传粉者友好做法的实施上。这可能是一个双赢的战略，因为生物多样性和作物生产都可能受益于这些地区更健康的花卉访客社区。
In the past decade, accumulating evidence of pollinator decline has raised concerns regarding the functioning of terrestrial ecosystems and the sustainability of crop production. Although land-use changes have been advanced as the major causes, the affinities of most wild pollinators with the main land-use types remain unknown. Filling this gap in our knowledge is a prerequisite to improving conservation and management programmes. We estimated the affinity of flower visitors with urban, agricultural and natural land-uses using data from a country-wide scale monitoring scheme based on citizen science (Spipoll). We tested whether the affinities differed among insect orders and according to insect frequency (frequent or infrequent). Our results indicate that the affinities with the three land-use types differed among insect orders. Apart from Hymenopterans, which appeared tolerant to the different land-uses, all flower visitors presented a negative affinity with urban areas and a positive affinity with agricultural and natural areas. Additionally, infrequent taxa displayed a lower affinity with urban areas and a higher affinity with natural areas than did frequent taxa. Within frequent taxa, Hymenoptera and Coleoptera included specialists of the three land-use types whereas Diptera and Lepidoptera contained specialists of all but urban areas. Our approach allowed the first standardised evaluation of the affinity of flower visitors with the main land-use types across a broad taxonomical range and a wide geographic scope. Our results suggest that the most detrimental land-use change for flower visitor communities is urbanisation. Moreover, our findings highlight the fact that agricultural areas have the potential to host highly diverse pollinator communities. We suggest that policy makers should, therefore, focus on the implementation of pollinator-friendly practices in agricultural lands. This may be a win-win strategy, as both biodiversity and crop production may benefit from healthier communities of flower visitors in these areas.
