An Evaluation of the Role of Sensory Drive in the Evolution of Lake Malawi Cichlid Fishes
Figure 3
The relative quantum catch various opsin pigments for sample environments in Lakes Malawi and Victoria along depth gradients. The relative quantum catch of both short- (a) and long-wavelength (b) pigments is relatively constant in Lake Malawi. In Lake Victoria the short-wavelength pigments rapidly lose the ability to catch light with depth (c) while the relative quantum catch of the LWS pigment increases rapidly (d). Relative Qc represents the quantum catch (photons) of each cone pigment normalized to the total quantum catch for all pigments.
