   this population information to predict the long-term impact of beaver introductions in areas currently without any beavers, or with small populations. Population data have historically come from regions where beavers were subjected to trapping and hunting pressure. However, in most parts of the United States, there is at pre­

   A population pyramid is a graphical representation of the age and sex composition of a specific population. There are several different types of population pyramids that can be observed, each indicating specific demographic patterns and characteristics. Here are the main types of population pyramids: 1.

   Population pyramid types. Demographers recognize three prototypical pyramid structures, constrictive, expansive, and stationary. All indicate conditions of the populations which comprise them. A con-strictive pyramid has fewer people in the younger age categories, and has been typical of U.S. populations as baby boom populations shift to more

   Activity 1 – Diferent Types of Population Pyramids. Births, deaths and migration determine the shape of a population pyramid, so pyramids can represent the diferent stages of population growth. Assign the texts to the appropriate graphic and explain your reasoning.

   Are beavers pre-reproductive?

   • In 1974 Hodgdon re ported that 59.2% of the population was pre-reproductive animals (yearlings and kits) (Hodgdon, 1978). In 1988 only 32.5% of the population was pre-reproductive. In 1974, 2-year-old beavers were only 3.5% of the total population while in 1988 they were 20%. This suggests a reduction in dispersal of these young adult animals.

   How many lions does a beaver have?

   • Using data published by Naiman, Melillo, and Hobbie (1986) the beaver population is estimated to be between 6 and 12 mil lion at the present time. The increase in regional beaver populations, particularly in states with high human densities, has in turn led to an increase in the number of beaver nuisance reports.

   How many types of Population pyramids are there?

   • Demographers have di-vided population pyramids into three prototypical types (Fig. 83). While these prototypes are useful for general interpretation of conditions, knowl-edge of specific characteristics of particular populations is also important as they may significantly contribute to differences between counties. Figure 83.
