Figure 1. Matrices depicting interactions between plants and pollinators across five entire flowering seasons of study among six plots in a subalpine meadow in the Colorado Rocky Mountains, USA. Interactions are organized in a nested organization such that interactions on the top-left corner represent the most generalized interactions in the network. Cells coloured in grey represent unrecorded interactions while those filled with heat ramp colours indicate the occurrence of interactions with higher values represented by “hotter” colours. These values indicate: A) number of years in which an interaction was recorded, B) average interaction phenophase (maximum date – minimum date in which an interaction was recorded) across five years of study depicted in weeks (7-day bins), and C) number of plots in which each interaction was recorded.
