Estimation of a Nonlinear Density‐Dependence Parameter for Wild Turkey

摘要: Abstract Although previous research and theory has suggested that wild turkey (Meleagris gallopavo) populations may be subject to some form of density dependence, there been no effort estimate incorporate a density-dependence parameter into population models. To functional relationship for dependence in turkey, we analyzed set harvest-index time series from 11 state wildlife agencies. We tested lagged correlations between annual harvest indices using partial autocorrelation analysis. assessed the ability density-dependent theta-Ricker model explain over relative exponential or random walk growth homogeneity estimates (θ) 3 different (spring no. reported harvest/effort, survey harvest/effort) calculated weighted average based on each estimate's variance its estimated covariance with other indices. po...
