Szukana fraza: [Opis = "Populations of small mammals were simulated and samples collected from them to determine comparative strengths and weaknesses of the population estimates most commonly used. All experimental samples were collected with population parameters known, each being modified to assess how the estimators respond to presumed population behavior of small mammals. Population parameters we modified were densities activity ranges and birth and death rates. These parameters were adjusted to simulate presumed extremes for naturally occuring populations."]
