Results of AIC model comparison to explain incubation shift length and reproductive success of murrelets.

Notes– Wi = Akaike weight; K = number of parameters; ISL = Incubation Shift Length, RS = Reproductive Success;*Indicates interaction between variables; egg = egg volume index (Length × breadth2) for 1st egg; pr_isl = duration of the previous incubation shift length ( = partner's trip duration, days); end = date of incubation completion; X6H = wind speed 6 hours prior to colony arrival at 23:00; X72H = wind speed 72 h prior to colony arrival at 23:00; moon = proportion of moon (full moon: 14-day, new moon: 1-day); cloud = daily cloud opacity; COR = nest specific correlation coefficients; neg = cumulative days of egg neglect at each pair; ISL = mean incubation shift length at each nest; year = Year of observation.
