Big Game Ecology Test 1 Review Label the parts of the logistic population curve. List 5 characteristics of a population 1. Birth rate 2. Death rate 3. Density 4. Sex ratio 5. Age structure Provide Leopold’s 5 phases of wildlife management. 1. Restriction of hunting (season, bag limits) 2. Predator control (bounties, government control programs) 3. Establishment of refuges 4. Artificial replenishment (exotics, game farms, hatcheries, stocking). 5. Environmental controls (habitat management and scientific studies). Define the following terms or commonly used abbreviations population - A population is a biological unit at the level of ecological integration when it is meaningful to speak of a birth rate, a death rate, a sex ratio, and an age structure in describing the properties of the unit" at a specific time and place r - Exponential rate of increase λ - Annual finite rate of increase parasitology Epizootic- Diseases are ENZOOTIC in the chronic form and EPIZOOTIC when they erupt Productivity -producing readily or abundantly Precision -A measure of the repeatability of the measurement Theory -a coherent group of general propositions used as principles of explanation for a class of phenomena Density dependence Compensatory mortality - In the simplest form, one type of mortality replaces another Natural regulation Accuracy -A measure of the closeness of an estimate to the true value Bias -systematically distorting estimate in one direction Regulating factors Limiting factors -Natural and man-made “limiting factors” for land, wildlife, and water must be identified and considered during initial planning in the context of desired goals Index -An index is a census or estimate of some object related to the number of animals or some other parameter of interest Taxonomy -the science dealing with the description, identification, naming, and classification of organisms CITES - Type specimen UTMs - Universal Transverse Mercator ►Not continuous for planet

►Between 80°S latitude and 84°N latitude; Earth divided into 60 zones, each zone in 6° longitude. ►Each zone around prime meridian (longitude for that zone). Census -defined as a total count (rare in wildlife biology, usually must use a sampling procedure to get an estimate. Samples have variability which is usually expressed as standard error Indice - Census or estimate of some parameter which is related to the number of animals Biologists commonly attempt to estimate birth rates, death rates, and rates of increase. Which of these parameters is the most useful and why? Rate of increase-it is the easiest to understand Provide 3 reasons on why is it better to use r rather than λ when discussing populations? 1. Centered at zero. Zero = stable population 2. r converts easily from l unit of time to another 3. Can calculate doubling time by using rb. λ is a constant =0.6931, (0.6931/r) A wildlife biologist tells you that predation is regulating his herd growth. What does he mean? Natural predation is regulating his herd population?
