SEASONAL CHANGES OF THE TESTES IN THE MARSH FROGE RANA RIDIBUNDA PALLAS, 1771	2002	6	.pdf	application/pdf	1792	130	77	From the results obtained from the present work on Rana ridibunda and from the observations on annual cycle in testis weight of some temperate zone anurans we notice that testes tend to be lowest after spawning and the testis cycle seems to be correlated with geographic range of distribution. Testis weight has continuously increased in May sample until reached its greatest average weight in August (0.785%) Table (1): Mean percent testis weight (g) of the marsh frog Rana ridibunda.	cache/binhm-174.pdf	txt/binhm-174.txt
