Temp of embryogenesis and eliminating embryos common gull in the Turenets colony

The rate of embryogenesis of the common gull was studied within the colony located on the Island Turenets (Il’inskii District, Perm Region). The development of embryos is characterized by asynchrony. The duration of incubation ranges from 21 to 26 days. The level of elimination of embryos in the colony reaches 6,6%. The most critical period of embryogenesis falls at the first day. The heterochronia of embryonic development of the common gull appears not only within the masonry, but also within the entire micropopulation (of the colony on the island), which provides its phenotypic heterogeneity.
