translate English to French: The relationship between the spring and autumn harvest was evaluated by determining the population growth rate, assuming that all of the harvest occurred in autumn, and then iteratively finding the harvest rate that would allow the same population growth rate if all harvest occurred in spring.
La relation entre la chasse printaniÃ¨re et la chasse automnale a Ã©tÃ© Ã©valuÃ©e en dÃ©terminant le taux de croissance de la population, en prÃ©sumant que toutes les prises sont faites en automne, et en trouvant alors de maniÃ¨re itÃ©rative le taux de prise qui donnerait lieu au mÃªme taux de croissance de la population si toute la rÃ©colte survenait au printemps.
