Precision of Population Viability Analysis

摘要: Although population viability analysis (PVA) is widely used in setting conservation policy, there disagreement about the usefulness of this method. Objections have been raised concerning precision predictions view short time series data available and sensitivity estimates extinction risk to estimated parameters (Hamilton & Moller 1995; Taylor Groom Pascual 1998; Ludwig 1999). Beissinger Westphal (1998) reviewed use demographic models for endangered-species management. They pointed out that poor cause difficulties parameter estimation, which turn lead unreliable risk. There are additional
