Forests in the High Allegheny Unglaciated Plateau Subsection of Pennsylvania and New York, including the Allegheny National Forest, have been increasingly impacted by an array of native and introduced forest insects, pathogens, plants, and other disturbances for decades.

In this study we analysed 750 quantitative plant–pollinator networks from 28 studies representing diverse biomes worldwide. We show that the potential for one plant species to influence another indirectly via shared pollinators was greater for plants whose resources were more abundant (higher floral uni...
