全球范围内传粉者的栖息地正在减少，这威胁着野生和农业生态系统的健康。光伏太阳能装置正在蓬勃发展，且常常靠近农田，而地面安装的光伏板下方的土地传统上是未被利用的。美国的一些太阳能开发商和农业从业者正在光伏板下种植传粉昆虫的栖息地植物，以努力实现农田土地利用效率的最大化。然而，太阳能板顶棚对下方传粉者 - 植物群落的影响尚不清楚。在此，我们研究了6月至9月（盛花期之后）太阳能电池板下的全阴地块、部分遮阴地块以及太阳能电池板外的全阳地块（对照）中，太阳能电池板阵列对植物组成、开花时间和传粉者觅食行为的影响。我们发现部分遮阴地块的花卉数量增加，开花时间延迟，这有可能使缺水生态系统中的晚季觅食者受益。全阳地块和部分遮阴地块的传粉者数量、多样性和丰富度相似，且都多于全阴地块。在这个尺度上，不同处理间传粉者访花率没有差异。这表明尽管遮阴梯度下群落结构存在差异，传粉者仍会利用太阳能电池板阵列下的栖息地。我们预计这些发现将为管理太阳能电池板下植被的当地农民和太阳能开发商，以及为在目标区域寻求传粉者栖息地恢复用地的农业和传粉者健康倡导者提供信息。
Habitat for pollinators is declining worldwide, threatening the health of both wild and agricultural ecosystems. Photovoltaic solar energy installation is booming, frequently near agricultural lands, where the land underneath ground-mounted photovoltaic panels is traditionally unused. Some solar developers and agriculturalists in the United States are filling the solar understory with habitat for pollinating insects in efforts to maximize land-use efficiency in agricultural lands. However, the impact of the solar panel canopy on the understory pollinator-plant community is unknown. Here we investigated the effects of solar arrays on plant composition, bloom timing and foraging behavior of pollinators from June to September (after peak bloom) in full shade plots and partial shade plots under solar panels as well as in full sun plots (controls) outside of the solar panels. We found that floral abundance increased and bloom timing was delayed in the partial shade plots, which has the potential to benefit late-season foragers in water-limited ecosystems. Pollinator abundance, diversity, and richness were similar in full sun and partial shade plots, both greater than in full shade. Pollinator-flower visitation rates did not differ among treatments at this scale. This demonstrates that pollinators will use habitat under solar arrays, despite variations in community structure across shade gradients. We anticipate that these findings will inform local farmers and solar developers who manage solar understories, as well as agriculture and pollinator health advocates as they seek land for pollinator habitat restoration in target areas.
