WebThe set of wavelengths absorbed by a pigment is its absorption spectrum. In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and β-carotene. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. WebSep 7, 2024 · In accordance with the hypothesis, green-wave surfing, which was defined as a close tracking of the spatio-temporal shifts in new vegetative growth [ 4 ], was most prominent in landscapes with rapid, narrow and well-ordered green-up trajectories. In contrast, in less surfable landscapes, populations were less likely to be migratory. WebNonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking.
