Krill population dynamics in the presence and absence of salps. Boxplots displaying the distribution of post-larvae krill density (top left panel), mean post-larvae krill length (top right panel), number of eggs released by krill per year (bottom left panel), and salp density (bottom right panel) for the model runs and the years 30–100. The boxplots are separated by chlorophyll-a scenario (x-axis of each plot) and competition with the other species, respectively (coloring of boxplots)
