Phenotypic plasticity in fish
WebNov 11, 2024 · Plasticity may allow an individual to develop a phenotype that confers fitness advantages in specific environmental conditions [ 2 ]. For example, studies in Daphnia spp. have demonstrated that individuals develop a defensive helmet when they detect predator cues in their environment [ 3, 4 ]. WebApr 1, 2024 · Color patterns in reef fish, with their extreme divergence and plasticity, can indeed be considered as a ‘ magic trait ’ that may easily lead to speciation [53]. Thanks to work on the zebrafish model, we have more knowledge about the developmental mechanisms generating color patterns.
