註釋A study was conducted on Theodorou island (68 hectares) during 1973 to determine the population energy relationship of the Cretan wild goat or agrimi. The density, sex and age ratios, individual weights and other pertinent data of the agrimi on Theodorou island were obtained by direct measurement of the total population. In 1973 the population density was 1.4 individuals/hectare. The sex ratio was 1:1 among both kids and adult. The kid:adult ratio was 14:100, while the kid:female ratio was 36:100. From weight data a body growth curve was constructed. The following agrimi population parameters were also calculated: life expectancy, 5.9 years; net reproductive rate, 1.14; annual turnover, 14.9%; annual mortality rate, 15,7%; innate rate of increase, 2.09/100/year; and generation time, 6.8 years. The present agrimi population was found to be causing serious ragne deterioration. To insure the permanent preservation of the agrimi population and its range a calculated 33% reduction of the population is recommended.
