Each year, many groups failed to produce offspring or the offspring were depredated prior to sampling. |
First, the rate at which eggs were depredated was analyzed with survival analysis. |
Because egg predation is high during laying, many eggs may have been depredated before we found them, especially the first and second eggs of a clutch. |
If eggs hatched and were then depredated within three days, failure may have been incorrectly assigned to the incubation stage. |
As in Q1,2, the purpose would have to be stated in terms of biological consequences for the groundfish being depredated. |
The number of eggs depredated by ghost crabs was estimated by counting those eggs that had a small circular section of the eggshell removed. |
