Estimated ratio out of diet plan because of the chick-rearing period and you will breeding nest
Type when you look at the ? fifteen N thinking one of breeding territories differed according towards hottie-rearing several months (Fig cuatro)
The latest communication between reproduction colony and you may hatching time revealed that the change in ? thirteen C viewpoints with hatching time varied among reproduction territories. Merely inside Suhaam, ? 13 C beliefs of chicks improved 0.24 ± 0.07‰ a day (0.10–0.38‰/day) along the hottie-rearing period, if you are there’s zero proof of alter towards other colonies (Gujido: -0.04 ± 0.10‰/time -0.24–0.15‰/day; Namdongji: 0.02 ± 0.06‰/big date -0.10–0.13‰/day; Chilsando: -0.05 ± 0.09‰/time, -0.23–0.12‰/day).
Getting ? 15 Letter, an entire model differed significantly in the null design (? dos = , df = 12, p 2 = 8.54, df = step 3, p = 0.036) and you can reproduction colony and you may hatching go out (? dos = nine.23, df = step three, p = 0.026), as interaction anywhere between chick-rearing several months and you can hatching go out to possess ? 15 Letter wasn’t extreme (? dos = 1.09, df = step 1, p = 0.292; S2 Dining table). The low model revealed that ? fifteen Letter philosophy away from girls differed anywhere between hottie-rearing symptoms just when you look at the girls at the Chilsando, in which ? 15 N beliefs into the late hottie-rearing several months were step one.01 ± 0.33‰ all the way down (0.33–step one.68‰) than those at the beginning of hottie-rearing several months (Fig 4). There can be zero proof of a big difference in ? 15 Letter beliefs anywhere between hottie-rearing symptoms during the other colonies (Gujido: -0.04 ± 0.45‰, -0.95–0.88‰; Suhaam: -0.01 ± 0.39‰, -0.81–0.77‰; Namdongji: -0.25 ± 0.42‰, -step 1.10–0.59‰; Fig 4). Towards very early hottie-rearing season, new feathers regarding girls at Gujido encountered the lower ?
