Fig. 1: Map of study sites of different biomes and isotopic fractionation factor (αR) values tested in the models.
From: High rates of daytime river metabolism are an underestimated component of carbon cycling
a Map using green triangles to note temperate river sites, yellow circles for desert sites, red squares for tropical sites, and a blue pentagon for the sub-arctic site. b Gray dots represent average measured αR values within each study site and black bars indicate ±1 SD. Modified figure from ref. 30. Circle sizes are proportional to water temperature (as an average during the time of measurement) in each site. Pictures illustrate rivers' characteristic of each biome and show that our sites were mostly open canopy in all biomes.
