and egg deposition takes place there immediately. A highly successful male may have three or four egg clutches on his leaf, each consisting of only about two dozen eggs. Upon hatching, the tadpoles drop into the streambed; if a tadpole lands on a stone, it flips about vigorously until it ...
Old embryos (4days old) subjected to direct katydid predation had more immediate responses, hatching <1h after predation on average. Hatching time was not correlated with female frog size, egg attendance time, or other predator cues. Results confirm predator-cued hatching in a new family of ...
For the first week or two after hatching, tadpoleswon’t move around very much, as they’re still absorbing somenutritionfrom the yolk of their egg. However, once the yolk is all gone, the tadpoles arebig and strong enoughtoventure outinto their watery world! Unlike adult frogs, tadpolesca...
Such larvae may be removed from their gelatinous cases for purposes of operation, and reared in "normal" salt solution until the proper hatching time, when they may be gradually transferred to fresh water. After treatment of this kind, many of Prof. Born's larvae have metarnorphosed into...
With easily found clutches and a short hatching time, rice frogs provide an ideal opportunity to test the effects of egg size on offspring fitness. In this paper, according to the life-history theory and the characteristics of rice frogs, we tried to answer the following questions: (1) does...
(Figure 2J). Cowbird eggs hatch after 12 days of incubation; if the cowbird female lays her egg too late into the host’s nest, incubation time will have expired before her chick hatches. However, if she lays her egg too early in the host nest, she risks her egg being discovered and...

they are when they hatch. Some have a stumpy tail and can barely swim; others are fully formed, four-limbed animals. “How do you get that kind of evolved variation?” Warkentin asks. “Does plasticity in hatching time play a part in that? We don’t know, but it’s quite possible...
green frog tadpoles metamorphose into frogs in the same season in which they hatched, while in the northern part, 1 or 2 years pass before metamorphosis. Tadpoles that hatch from egg masses laid in the spring usually metamorphose that fall, while those hatching from summer-laid eggs typically ...
