... effects of two stressors (high temperature and hypoxia) in yolk-sac larval (48–168 hpf) zebrafish ( Danio rerio ) energy budgets measuring, oxygen consumption rate, growth rate (absolute and specific), % net conversion efficiency, net cost of growth and scaling relationships. Embryos and larvae were...

... crystal's surface and restrict its growth within a certain temperature range. We investigated the ability of an antifreeze protein from the desert beetle Anatolica polita , Ap AFP752, to confer cryoprotection in the frog Xenopus laevis . Xenopus laevis eggs and embryos microinjected with Ap AFP752 exhibited...

...Bodil Korsgaard ABSTRACT The ability of blenny Zoarces viviparus (L.) embryos in early and late development to assimilate and metabolize ambient L-alanine was investigated in vitro and in vivo by means of autoradiographic and radiochemical methods. Autoradiograms showed that after 24 h of exposure...

...) whether urea accumulating inside eggs might be the cause of reductions in metabolism and growth by embryos. Eggs in the first experiment were incubated in different hydric environments to induce different patterns of net water exchange between the eggs and their surroundings. Turtles hatching from eggs...

...Gregg A. Kormanik ABSTRACT Embryos of the dogfish Squalus acanthias (L.) complete their development in a uterine environment that is quite unusual. During the latter portion of a gestation period which lasts nearly 2 years ( Hisaw & Albert, 1947 ), the embryos are bathed by a uterine solution...

...Mary J. Packard; Gary C. Packard; William H. N. Gutzke ABSTRACT Total calcium in embryos of an oviparous, colubrid snake (Coluber constrictor L.) rises rapidly during the last half of incubation as the embryos increase in size. Although most of this calcium is drawn from stores in the yolk...

... on the dry substrate. Thus, embryos are ureotelic throughout development, and the pattern of accumulation of the primary nitrogenous waste is influenced by hydration of the environment. 18 07 1983 © 1984 by Company of Biologists 1984 Thus, our data indicate that embryonic snapping turtles...
