, What is the Definition of Population? - CORRECT ANSWERS-A group of individuals of
a single species living in the same general Area.-Have same resources -Influenced by
same enviromental factors -Likely to interact and breed with one another.
What is Population Genetics? - CORRECT ANSWERS-Uses math and empirical
studies to understand allele frequency distributions and changes, including those that
lead to adaptation and speciation
What is Population Ecology? - CORRECT ANSWERS-Study of populations in relation
to their environment.
What are the 4 environmental influences? - CORRECT ANSWERS-1)Density
2)Distribution 3)Age structure 4)Dynamics (changes in size)
What is a closed population? - CORRECT ANSWERS-Where membership is stable.
Changes in Population only happen through Birth or Death.
What is an open population? - CORRECT ANSWERS-Where membership (# in pop)
can change. This can be due to immigration and emigration as well as Birth and death.
What is Population Density? - CORRECT ANSWERS-Result of an interplay between
process that add individuals to a population and those that remove individuals (Births
and Immigration add whereas Deaths and Emigration remove)
What are some simple cast assumptions for annual plants and insects? - CORRECT
ANSWERS-1)Rate of reproduction of an individual remains constant.2)Individuals only
breed once, generations do not overlap.
Another Simple Case assumption? - CORRECT ANSWERS-The rate at which a
population increases is a simple multiple of the number of individuals already present in
the populations.Ex: Gen 1: 10 Individ Gen 2: 10 X 2 Indiviud Gen 3: 10 X 4 indivud
What is the Exponential Population equation? - CORRECT ANSWERS-N(t)=R^t * N(i)
Ex: What is the population size if we start with 1000 individuals with net replacement
rate per generation of 2 and watch them increase for 5 generations?N(5)= 2^5 x 1000 =
32,000
What is the rate of increase if it increases in size by 50% in one generation? -
CORRECT ANSWERS-R= 1.5
A population was observed to increase from 5000 to 6000 individuals in one year, What
is the rate of increase? - CORRECT ANSWERS-Rate of increase = 6000/5000
