Countergradient variation in embryonic growth and development: do embryonic and juvenile performances trade off?
1. Countergradient variation in growth rate requires that rapid growth rate trades off with other performances, such that submaximal growth evolves in certain environments. Negative effects of rapid growth on other traits within a single ontogenetic stage are conspicuous candidates for such trade-offs, but trade-offs spanning ontogenetic stages have received much less attention. 2. We tested wh...
متن کاملEmbryonic development and growth performances of an endangered fish species Nandus nandus: effects of dietary polyunsaturated fatty acids supplementation
The present study explored the embryonic and larval development of an endangered fish species Nandus nandus and resolved larval growth performances with the dietary supplementation of different types of lipids. Fertilized eggs were collected from fiber glass tanks immediately after spontaneous spawning of N. nandus, which were fed with a 1% phospholipid (squid meal) supplemented diet for 3 mont...

متن کاملEmbryonic, larval and juvenile development of tropical sea urchin, Diadema setosum
Diadema setosum (Leske, 1778), is one of the common echinoids widely distributed in the Indo-West Pacific Ocean, where it occurs from the Red Sea, Persian Gulf and the east coast of Africa to Japan, Australia and Malaysia. To investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of D. setosum in a controlled laboratory condition at the In...
