Figure 4From: Modeling the population dynamics of lemon sharksCircles represent region of the parameter space in which simulations were a “good” fit to the data (seeMethods). Left: Half-saturation value (k, density-dependence parameter for the first-age class mortality rate) versus the mortality rate for subadults and adults for series of combinations utilizing the actual distribution of litter sizes for fecundity rate. Right: Same as left but uses a Poisson distribution for fecundity rates. Both pictures represent cases when λ was set at 6.1 for the Poisson distribution which is equivalent to the average of the actual distribution of litter sizes.Back to article page
