人类世的一个重要特征是生态系统服务功能的侵蚀，生物多样性的减少，以及曾经常见的生物体丰度的总体减少，其中包括许多在支持人类社会的自然群落和农业系统中发挥无数作用的昆虫。现在很清楚，保护昆虫不能仅仅依靠对远离人类居住区的自然区域的法律的保护。相反，未来的一个关键挑战是智能地管理包括密集耕作景观的地区，例如加州的中央谷。在这里，我们试图迎接这一挑战，为昆虫（特别是在头脑中的传粉者），建立在现有的信息，包括杀虫剂的致命性和专家意见的昆虫运动的景观连接建模的工具。尽管中央谷的大规模分裂，我们发现连通性是可能的，特别是利用恢复或改善农业边缘，其中（在其总面积）超过自然面积。我们的建模方法是灵活的，可用于解决有关土地覆盖变化以及农药施用率变化的各种问题。最后，我们强调了可以向前推进的关键步骤，以及可以在该领域解决的大量知识差距，以改进我们建模方法的未来迭代。
One of the defining features of the Anthropocene is eroding ecosystem services, decreases in biodiversity, and overall reductions in the abundance of once-common organisms, including many insects that play innumerable roles in natural communities and agricultural systems that support human society. It is now clear that the preservation of insects cannot rely solely on the legal protection of natural areas far removed from the densest areas of human habitation. Instead, a critical challenge moving forward is to intelligently manage areas that include intensively farmed landscapes, such as the Central Valley of California. Here we attempt to meet this challenge with a tool for modeling landscape connectivity for insects (with pollinators in particular in mind) that builds on available information including lethality of pesticides and expert opinion on insect movement. Despite the massive fragmentation of the Central Valley, we find that connectivity is possible, especially utilizing the restoration or improvement of agricultural margins, which (in their summed area) exceed natural areas. Our modeling approach is flexible and can be used to address a wide range of questions regarding both changes in land cover as well as changes in pesticide application rates. Finally, we highlight key steps that could be taken moving forward and the great many knowledge gaps that could be addressed in the field to improve future iterations of our modeling approach.
