Chapter 53.1, Problem 2CC
Summary Introduction
To construct: A life table for various populations of the Belding's ground squirrels.
Concept introduction: Demography: is referred as the study of a population's vital statistics like the migration rates, death and birth rates. It is also responsible for studying the changes with respect to time that occurs in the vital statistics. Therefore, for summarizing the information (demographic) life table is important to be made.

Q6.9. A dwindling population of 1000 frogs occupies an isolated area in Costa Rica. To help
preserve the species, scientists caught 20 frogs to start a new population in a nearby area. This
species has a gene that affects eye shape. The 1000-member wild population has two alleles for
this gene: R and r, with frequencies 0.7 and 0.3, respectively. What will be the allele frequencies
of R and r in the 20-member founder population?
The frequencies will be 0.7 for R and 0.3 for r.
The frequencies will be 1.0 for R and 0 for r.
The expected frequencies are 0.7 for R and 0.3 for r. The actual frequencies could be different.
The founder populations's allele frequencies will necessarily be different than the source
population's frequencies.

- In the greater ani (Crotophaga major) (Riehl 2011) and the acorn woodpecker (Melanerpes formicivorus) (Koenig et al. 1995), a group of females shares the same nest. However, when some females begin to lay eggs in the communal nest, their eggs are often tossed from the nest by other group members. Use a cost–benefit approach to explain why females whose eggs are destroyed still remain with the group. Do you think the egg-tossing females are really cooperating with the others in their group?
