Warming temperatures affect meadow‐wide nectar resources, with implications for plant–pollinator communities

Abstract Nectar production may be a point of sensitivity that can help link primary and secondary trophic responses to climate shifts, is therefore important our understanding ecosystem responses. We evaluated the nectar response two widespread native forbs, Balsamorhiza sagittata Eriogonum umbellatum , experimental warming in high‐elevation sagebrush meadow Teton Range, WY, USA, over years, 2015 2016. Warming treatments reduced occurrence nighttime freezing volume but increased sugar concentration both species years. effects were also evident consistent increase number flowers produced by B. . Our research suggests associated with change has potential induce shifts nectar‐feeding community changing characteristics such as which feeders are adapted.
