It is also possible that the single point samples were not sufficient to detect differences in pulsatile LH secretion between groups, as has been suggested previously for rats induced to become photoperiodic by androgen treatment [ 8 ] . It would be useful to repeat this comparison of hormone levels using multiple samples obtained from indwelling atrial cannulas.
These results have implications for studies on F344 and other photoperiodic strains of rats, particularly because the F344 rat is widely studied throughout the world, and has been the most commonly used inbred rat strain in the United States [ 32 ] . The existence of both reproductive and nonreproductive responses of adult F344 rats to short photoperiod, and the possibility for weak endogenous circannual responses to short photoperiods could complicate the design and interpretation of experimental results, especially in the case of long-term studies.
In addition, adult F344 rats were tested for evidence of an endogenous rhythm of photoperiodic responses, by assessing whether mature rats that had become insensitive to short winter photoperiods would regain sensitivity in constant short photoperiod.
In species of hamsters that show photoperiodic regulation of body weight, there is evidence that decreases in body weight in SD can be independent of changes in food intake [ 17 ] or caused at least in part by decreases in food intake [ 18 ] .
