β¦ Synopsis
Low doses of 1-thyroxin promote feather regeneration and lead to significant reduction in the mean weight of the gonad of adult normal and thyroidectomized Spotted Munia, Uroloncha punctulata, in the breeding phase. At moderately high doses of thyroxin complete molting occurs, and the mean weight of the gonoduct is also significantly reduced. The effect of 1-thyroxin increases as the duration of ad-

## Abstract The present study was designed to examine the role of circadian organization in the control of seasonality in the seasonally breeding spotted munia, __Lonchura punctulata__, which does not utilize photoperiod to time its reproduction under natural dayβlength conditions. Daily injection
Spot size in descendants from the Goodale white-spotted stock of mice responded to selection for increased spot size. The realized heritability estimate was 0.52. However, no correlated response of reproduction to spot size selection was found in the present study, nor was there any correlated respo
Recent research suggests that overweight females suffer penalties in the labor and marriage markets, while overweight males do not. This study explores whether similar gender differences in the effect of body weight exist in what Cawley et al. (2006) labeled 'the adolescent sex market'. Drawing on d
