Stochastic Simulation of Temperature Effects on First-Year Survival of Smallmouth Bass

摘要: Abstract The physiological basis for well-known correlations between summer air temperature indices and year-class strength in northern smallmouth bass (Micropterus dolomieui) populations was examined. Field laboratory studies demonstrated the existence of two critical stages early life when are particularly vulnerable to features characteristic many natural water regimes. first stage extends from fertilization until young leave nest; high mortality results exposure extreme temperatures. second over winter, subsist on accumulated energy reserves. Because ratio stored basal metabolic rate increases with size, large fish can withstand winter starvation better than small fish. these other were incorporated into a deterministic model relations first-year survival small-mouth bass. Analysis time series data from...
