Populations
The number of individuals per unit of space is the
density
In addition to observation, development of a hypothesis and experimentation, the scientific method includes
analyzing results and drawing conclusions
The effect of reduced genetic diversity on the decline of the Florida panther was due to
inbreeding
What are ecosystem services?
Benefits humans receive from nature for free
The efficiency of energy transfer at each trophic level is approximately
10%
The pattern of population growth that declines with increasing density is
logistic growth
The middle data value in a list of sorted data in a data set is the
median
The major issue responsible for the decline of the jaguar was due to
retaliation for killing livestock
Two ways in which the theories of ecological economics differ from those of classical economics:
Include all external costs, questions assumption of constant growth
Species that exert strong effects on the communities they inhabit are
keystone species
Density dependent factors that affect logistic growth include
competition, crowding and predation
A hypothesis that states there is no statistically significant difference between two conditions is a null hypothesis
null hypothesis
The marine mammal that has declined as a result of bycatch in illegal gill nets in the Gulf of California is
the vaquita
Investment in carbon mitigation projects and selling the credit is:
Carbon trading
Predator and prey interactions that result in changes to multiple trophic levels are known as
trophic cascades
Fragmented populations connected through corridors such that gene flow still occurs, defined as a
metapopulation
Variation of the data around the mean can be measured as
standard deviation or standard error
The major factor resulting in the decline of koalas is
climate change
Cancelling foreign debt in exchange for the preservation of conservation lands is:
Debt for nature swaps
The effect of white nose syndrome on bats is:
starvation
The number of individuals a habitat can support is the
carrying capacity
The variable that is being tested compared to a control to determine an effect is the
treatment variable
The common factor resulting in the decline of the northern spotted owl and orangutan is
cutting of forest habitat
Travel to places to support habitat conservation is known as:
Ecotourism
An example of a mutualism between two species is:
sharks and remoras, plants and bees
