mortality rates will increase
a population can not pass its carrying capacity
What type of population growth is shown in part A of this graph?
Logistic growth

The Kaibab squirrel became its own species when a small population was isolated on the northern rim of the Grand Canyon. Which type of speciation is this?
behavioral isolation
mechanical isolation
temporal isolation
geographic isolation
Identify the density-dependent limiting factors
disease
fire
predators
hurricane
The type of survivorship curve that shows high fertility rates and early mortality is
Type 1
Type 2
Type 3
Individual species are well documented on a central registry
True
False
In general, which of the following is the best long-term method of preventing extinctions?
Breeding endangered species in captivity
Protecting the habitats of endangered species
Paying people not to kill endangered species
Providing food to endangered species in the wild
Removing predators from areas that contain endangered species
Over-exploitation of animals is likely to cause
species extinction
interspecific competition
behavioral isolation
speciation
If the gene pool of two populations are separated, the populations may develop into a new species. This is called
natural selection
speciation
genetic separation
interspecific competition
20 different species of galagos, also known as bushbabies, are found in Africa. Even though various species of galagos share habitats, they cannot interbreed with one another because of their differently structured genitalia. Which type of speciation is this?
behavioral isolation
mechanical isolation
temporal isolation
geographic isolation
Which of the following are typical characteristics of an R strategist?
Few offspring produced
Low levels of parental care
Long life expectancy
type 3 survivorship curve
When the limiting factors LIMIT the population, the J curve will not continue & levels off at the carrying capacity. This is called
population growth
linear growth
logistic growth
exponential growth
term used when discussing a population's death rate
Natality
fertility
Life expectancy
Mortality
Which type of strategist produces few offspring and has long term parental care?
(a)
A type of isolation in which 2 populations become separated by a physical barrier such as a canyon or river, preventing the two populations from interbreeding.
Geographic Isolation
Mechanical Isolation
Temporal Isolation
What are the 2 types of limiting factors?
Density Dependent
Temperature
Isolation
Density Independent
What is the term for the maximum population size that an environment can sustain indefinitely?
Carrying capacity
Population density
Biotic potential
Ecological footprint
Which type of isolation occurs when two populations reproduce at different times?
Geographic isolation
Behavioral isolation
Temporal isolation
Mechanical isolation
Which of the following is a density-dependent factor that can affect population size?
Natural disasters
Predation
Climate change
Seasonal changes
Which type of growth model is characterized by a rapid increase in population size followed by a stabilization at the carrying capacity?
Exponential growth
Logistic growth
Linear growth
Arithmetic growth
