The present study assumes that each molt
and feather character is independent.
(1983) recorded spring molt
in late May and an indistinct second molt
in late summer and early autumn for S.
Two methods were used to estimate molt
duration of the primary feathers (data from recaptures were not included).
increment was not significantly different in any treatment and the time to molt
was only significantly different in molt
3 for the small cage size between the intermediate and low ration (Tukey's HSD P < 0.05).
The samples were categorized into the following molt
stages: pre-solo, -17 to -8 days, and -6 to -1 days (premolt); 2 to 5 days, 6 to 8 days, and 9 to 12 days (postmolt); and post-solo.
We located specimens of 1 complete and 1 apparently incomplete family group collected in July 1920 and July 1948, which supplemented information on wing molt
of chick-rearing Ancient Murrelets.
The linear mixed model is a generalization of the more familiar analysis of variance that allows for relaxation of 2 of its key assumptions: that the data points are all independent and that the variability within each of the experimental groups (here the molt
, nonmolt, and postmolt groups) is equal.
Animals that have undergone the third molt
have ovaries with only pre-vitellogenic oocytes.
The average duration of the molt
period was 52.6 [+ or -] 8.0 days (n = 7; Table 2).
We scored birds undergoing active molt
of flight feathers (including primary, secondary, or both) and birds undergoing molt
of body feathers as absent, trace, light, medium, or heavy.
An individual scorpion may accumulate a number of molts
over its lifetime; these molts
may not be distinguished easily from carcasses, especially after becoming fossils, thereby complicating interpretation of the scorpion fossil record.
The experiment lasted 12 weeks (Four weeks for the molt
period and 8 weeks for the post molt
