... 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...
