Stochastic matrix models are frequently used by conservation biologists to measure the
viability of species and to explore various management actions. Models are typically …

The feasibility of reintroducing Wild Boar Sus scrofa to Scotland was investigated using the
predictions of a Geographical information System (GIS) and a Population Viability Analysis …

Matrix population models have entered the mainstream of conservation biology, with
analysis of proportional sensitivities (elasticity analysis) of demographic rates becoming …

In appearance and in habits, the suckermouth catfishes or “plecos” of South and Central
America (Loricariidae) are markedly different from the bullhead catfishes of North America …

This paper presents a review of demographically structured (or, frequency-based) models, in
which the individuals in a population are grouped into distinct classes. Structured models …

The status of the brown bear (Ursus arctos) in Spain has suffered a dramatic decline during
the last centuries, both in area and numbers. Current relict populations are suspected to be …

Spatially-explicit population models allow a link between demography and the landscape.
We developed a spatially-explicit simulation model for the red-cockaded woodpecker …

Sensitivity analysis can be defined as the set of analytical and simulationbased tools that
evaluates how changes in life-history attributes of a demographic model affect population …

Uncertainties about biological data and human effects often delay decisions on
management of endangered species. Some decision makers argue that uncertainty about …

One of the critical challenges in conservation biology is to develop quantitative methods for
evaluating the fate of populations that are threatened by human activities (Soulé 1987) …
