| simulated impacts of juvenile mortality on gulf of mexico sturgeon populations. | we used an age-structured computer model to assess the impact of changes in juvenile mortality on the gulf of mexico sturgeon population in the suwannee river, florida. we simulated population trends under four levels of annual juvenile mortality (20, 25, 30, and 35%). as the rate of mortality increased, population size decreased, and rates of population growth shifted from positive to negative. our models indicated that juvenile survival is important to the success of gulf sturgeon populations, ... | 2002 | 12806060 |
