Filtering by: Subject Fish populations -- Computer simulation

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:

Hirai, Takayuki

Abstract:

To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

Mark-recapture estimates of population parameters for selected species of small mammals

Creator:

Hammond, Ellen L.

Abstract:

I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

Computer simulation of animal population dynamics

Creator:

Milne, David M., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Two major objectives were accomplished. 1. A summary of the work done during 1970-71 on a single species intra-specific competition model was written. 2. A multispecies predator-prey model, incorporating the competition mechanism of the single-species model, was developed almost to completion. The single species model is a computer program that...
