11 Parsons, PA (1993) Am. Nat. 142, S5-S20 scapes. Our discussion has several recurrent
themes. One theme is the aforementioned issue of spatial scale. We will not specify a …

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 new edition of Invasion Ecology provides a comprehensive and updated introduction to
all aspects of biological invasion by non-native species. Highlighting important research …

They may influence us as individuals by their encouragement and guidance; they may affect
their community through their untiring commitment to service and the greater good; or they …

Metapopulation is the ecological term for assemblages of plant and animal species within
larger areas of space, with long-term survival of the species depending on a shifting balance …

Individual-based models are an exciting and widely used new tool for ecology. These
computational models allow scientists to explore the mechanisms through which population …

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

Regular grids or lattices are frequently used to study ecosystems, for observations,
experiments and simulations. The regular rectangular or square grid is used more often than …

Ecologists need a better understanding of how animals make decisions about moving
across landscapes. To this end, we developed computer simulations that contrast the …

A short review of cellular automata models in ecology is given. Introduction of a spatial
dimension into a discrete-time Markov chain leads to a class of cellular automata called …
