Data from: Egg mass polymorphism in Ambystoma maculatum is not associated with larval performance or survival, or with cell density of the algal symbiont Oophila amblystomatis

These data are from a 2018 study of larval morphology, performance, and survival in the spotted salamander (Ambystoma maculatum). We examined larvae of two egg mass color morphs: clear and white. We also quantified the density of algal (Oophila amblystomatis) cells on the egg capsules of embryos. The data correspond to our publication in Evolutionary Ecology.
