The analysis of animal and plant life cycles is central to the management and conservation of species. Furthermore, any understanding of the evolution of life history characteristics depends on traits such as life span, schedules of births and death, and growth and survival estimates. Plant and Animal Populations is a bridge from introductory ecology to both applied and theoretical demography. Emphasis is on the analysis of population data taken from a wide variety of organisms. Examples come from terrestrial and aquatic plants and also from animals found in equatorial rain forests to the arctic tundra. The computer programs provided are written in BASIC and include tools for population projection, matrix analysis using both sensitivity and elasticity, individual growth and survival models, and analysis of size-frequency distributions. Certain to be widely used both as a text and as a reference, Plant and Animal Populations addresses the ever-increasing challenges of documenting population demographic changes. eng
