It is generally approved the positioning, attendance, and you will safeguards of the colony may be the chief activities you to definitely influence this new stability regarding egg plus the rates away from colony predation ( Arnold ainsi que al. 1987, Martin 1995, Cresswell 1997). Constancy while in the incubation provides a good thermal ecosystem to the development of embryos and you can protects egg out of tall temperature which could apply to the hatchability ( Offer 1982). For the varieties where just one sex incubates, there’s a swap-out of anywhere between attendance and security of your own nest and you will restoration away from a good times balance ( Thompson and you may Ravelin 1987, Flint and you can Grand 1999). On top of that, colony attract can decrease the risk of eggs predation possibly from the active nest Korece kadД±n vs AmerikalД± kadД±n cover otherwise down seriously to a reduced total of the newest incubation age of eggs, and this a reduced amount of day he is confronted by predators ( Clutton-Brock 1991, Creswell 1997, Flint and Huge 1999). Thermal requirements away from embryos can get constrain the latest time and you may period of this new foraging travel while in the incubation ( Webb 1987) weiterlesen →
