✦ Synopsis

Abstract

The distribution of polyamines, putrescine, spermidine, and spermine is reported in the tissues of the lizard, Calotes versicolor. The levels of spermidine and spermine are higher than those of putrescine in all tissues and most tissues have more spermine than spermidine. Enzymatic decarboxylation of L‐ornithine is also demonstrated in the lizard tissues. Liver orthinine decarboxylase has optimal activity at about pH 6.8 and apparent Km (Michaelis constant) of 1.23 to 1.73 mM for L‐ornithine.

The differentiation and development of the testis in the lizard Calotes versicolor was studied histologically and histoenzymatically from the day of oviposition (stage 27) to 2 months after hatching. The study reveals the appearance of the gonadal component as a genital ridge at stage 27. The first

## Abstract The hatchlings of __Calotes versicolor__ and other congeners retain residual yolk for immediate post‐hatching needs. Excision of 8% yolk (β‰Œresidual yolk) from the eggs resulted in smaller hatchlings when compared to those emerging from sham operated eggs. However, hatchlings in both gro

In the brine shrimp, long-term (several days) osmotic and ionic regulation is controlled principally by the activity of Na'K'ATPase. However, short-term cell volume regulation in Artemia and most euryhaline crustaceans is not understood. In this study, Artemia stage 1 nauplii reared at 32 ppt salini

## Abstract We incubated eggs of __Calotes versicolor__ at four constant temperatures ranging from 24Β°C to 33Β°C to assess the effects of incubation temperature on hatching success, embryonic use of energy, and hatchling phenotypes that are likely to affect fitness.
