REPTILE POPULATION-DYNAMICS - A TRIAL OF SYSTEMS-ANALYSIS

A general scheme of simulating model is elaborated, which makes it pos sible to describe seasonal and annual dynamics of number and bioenerge tics in reptile populations. Using this model, description was made fo r 5 reptile species (3 lizards, a snake, and a turtle). Original data on population demography, food consumption and assimilation, body calo ric value were used to identify parameters of particular models. The f ollowing numerical results were obtained: [GRAPHICS] where X is averag e population density (ind/ha), B is biomass (g/ha), C is consumption r ate (MJ/ha/year), and P is production g/ha/year.
