Population viability analysis (PVA) is a process. It entails evaluation of data and models for a
population to anticipate the likelihood that a population will persist for some arbitrarily …

Population viability analysis (PVA) has become a commonly used tool in endangered
species management. There is no single process that constitutes PVA, but all approaches …

This book is a short introductory text for advanced undergraduates and graduate students in
ecology. Designed as a guide to the more commonly encountered mathematical models in …

Over the last 20 years, comprehensive strategies for treating measurement error in complex
models and accounting for the use of extra data to estimate measurement error parameters …

This document introduces the viable salmonid population (VSP) concept, identifies VSP
attributes, and provides guidance for determining the conservation status of populations and …

We examine why demographic models should be used cautiously in Population Viability
Analysis (PVA) with endangered species. We review the structure, data requirements, and …

Dynamical systems with random influences occur throughout the physical, biological, and
social sciences. By carefully studying a randomly varying system over a small time interval, a …

Interest in the dynamics of biological populations is quite old, its roots being traceable to the
dawn of civilization. Many illustrious names are associated with early mathematical theories …

MARSS is a package for fitting multivariate autoregressive state-space models to time-series
data. The MARSS package implements state-space models in a maximum likelihood …

The use of umbrella and flagship species as surrogates for regional biota whose spatial
distributions are poorly known is a popular conservation strategy. Yet many assumptions …
