Spatial aspects of connectivity have received considerable attention from ecologists and conservationists, yet temporal connectivity, the periodic linking of habitats, plays an equally important, but largely overlooked role. Different biological and biophysical attributes of ecosystems underpin temporal connectivity, but here we focus on resource continuity, the uninterrupted availability of foraging sites. We test the response of pollinators to resource continuity at community, population, and individual levels using a novel natural experiment consisting of farms with either single or sequential cropping systems. We found significant effects at the population level; colony density of an important crop pollinator (Bombus impatiens L.) was greater when crop floral resources were continuously available. However, we did not find significant effects at the community or individual level; wild bee abundance, diversity and body size did not respond to resource continuity. Raspberry farms with greater early season resources provided by blueberry had greater bumble bee populations, suggesting beneficial effects on resource availability due to crop diversity. Better understanding the impact of resource continuity via crop diversity on broader patterns of biodiversity is essential for the co‐management of biodiversity and ecosystem services.

穿越时间的走廊:资源的连续性会影响传粉媒介的社区,种群和个人吗?

连通性的空间方面已受到生态学家和保护主义者的极大关注,但是暂时性连通性(栖息地的周期性连接)起着同等重要的作用,但在很大程度上被忽略了。生态系统的不同生物和生物物理属性是时间连通性的基础,但是这里我们关注的是资源的连续性,觅食地点的不间断可用性。我们使用一个新颖的自然实验来测试传粉媒介对社区,人口和个人各级资源连续性的响应,该实验由具有单一或顺序种植系统的农场组成。我们发现了在人口层面上的重大影响;重要作物授粉媒介(熊蜂)的菌落密度当作物花卉资源持续可用时,L。)更大。但是,我们没有发现对社区或个人有重大影响;野蜂的丰度,多样性和体型对资源的连续性没有响应。蓝莓提供的早期季节资源更多的覆盆子农场的大黄蜂种群数量更多,这表明由于作物多样性而对资源可利用性产生了有利影响。更好地了解通过作物多样性带来的资源连续性对更广泛的生物多样性模式的影响对于生物多样性和生态系统服务的共同管理至关重要。
