Predator response diversity to warming enables ecosystem resilience in the Galápagos
Fig 4
Effects of temperature on the respiration and predation of four common invertebrate carnivores found on shallow subtidal rocky reefs of the Galápagos.
A) Thermal Performance Curves (TPCs) for each species based on measurements of mass-normalized respiration across a range of temperatures. B) The thermal optima (Topt) of respiration across the four predators, calculated from the TPCs. C) Functional responses of predation to temperature. Vasula were fed two snail prey (Engina pyrostoma and Columbella haemastoma) and the other three predators were fed the barnacle Megabalanus peninsularis. In B and C, solid horizontal lines are mean values and associated vertical shaded bars are ± 1SE, while in A shaded bars are 95% confidence intervals. We fit curves for each species in C using the geom_smooth function in ggplot2 to help visualize the predation TPCs. See Supplementary Information for additional details about the predation experiments and respiration measurements.
