Figure 19 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report

Figure 19: Opposing relationships with total phosphorus for the biomass of the two most common fish taxa among the large and deep lakes (average depth> 50 m). Data are whole-lake average biomass (in grams) of fish per vertical net battery. Note that the horizontal axis is on a log scale. Regression statistics for Coregonus are p-value = 0.005, R2 = 0.57 and perch are p-value = 0.004, R2 = 0.58. Shaded regions show thresholds for total phosphorus of 10 μg / L and 5 μg / L.
