Preliminary bird population dynamics and biomass model, A
Author(s):Swartzman, G. L. (Gordon L.); U.S. International Biological Program. Grasslands Biome
Date Issued:1969-12-10
In this paper a preliminary model for the population and biomass change over time is given for bird populations. The interaction between biologist and modeler in the development of the model and its parameters is emphasized. ...
