In an area with heterogeneous distribution of suitable habitats, the dispersion pattern of a population is probably
Which of the following statements about life tables (survival rates) is NOT true?
They are used to predict logistic growth
A Type I survivorship curve is level at first, with a rapid increase in mortality at old age. This type of curve is
Typical of humans and other large mammals
The middle of the S-shaped growth curve in the logistic growth model
Is the period when the population growth rate is the highest
The term (K-N)/K
Is zero when population size equals carrying capacity
The carrying capacity for a population is estimated at 500; the population size is currently 400 and rmax is 0.1. What is dN/dt?
8 (K=500) (rmax=0.1) (400)
In order to maintain the largest sustainable fish harvest, fishing efforts should
maintain the population density close to 1/2 K (beneficial to both)
Immigration and emigration are likely to play a role in population dynamics in
In a population in which offspring survival is quite low and the environment is inconsistent, one might expect..
Which of the following factors is not a density-dependent factor limiting a populations growth?
A very early fall frost
The human population is growing at such a fast rate because?
1) the age structure of many countries is highly skewed toward younger ages
2) the death rate has increased since the industrial revolution
3) technology has increased earths carrying capacity
4)fertility rates in many developing countries are above the 2.1 children per female replacement level
The demographic transition is the gradual shift from
exponential growth to logistic growth
an ecological footprint is
the size of a population in relationship to the resources it uses
the defense of a bounded physical space (lead to uniform dispersion)
the study of the vital statistics of a population, such as bird and death rates
provides age-specific survival data for a population
shows the number or proportion of members of a cohort still alive at each age
big-bang reproduction (all reproductive resources into a single effort)
making repeated reproductive efforts over a span of time
when the birth rate or death rate does not change as population density changes
if it rises with increasing population density
study of these variations in population size and the biotic and abiotic factors that cause them
