ENR 3300 Final Review Questions and
Answers 100% Solved
Which statement best applies to how privately owned forests are managed by the state of Ohio?
Ohio Division of Forestry provides service foresters for consultation on management
The distribution of forest land in the United States and the distribution of federal lands in the
United States: Reflects the westward expansion in the country with more federal land in
the west despite more second growth forests in the east
Managers of the Florida Keys ecosystem have become increasingly concerned with invasions of
the non-native lionfish. They have been continuously monitoring and assessing the abundance
and growth rate of the population since its introduction and have found that currently, the
population adds increasingly more individuals as the abundance of lionfish increases. This
suggests that the lionfish is ______ by density-dependent processes and exhibits ______
population growth. not regulated, exponential
t or f: If you were in an oak hardwood forest vs shortleaf pine forest the growth and yield of
these two forests would be the same if they were growing on similar site qualities. false
,The polar vortex during 2016 (which caused extreme low temperatures) greatly reduced both low
and high density populations of bluegill fish across lakes in the Midwest. The polar vortex is an
example of what type of process? density independent
You are surveying a forest and measuring the diameter of every tree in your plots. When you get
back to the office, you notice that there are many more smaller diameter trees than larger
diameter trees. What would this tell you about this forest stand? The forest is young and
growing fast
In a study of ground squirrels you document that young squirrels tend to disperse further
distances when resources are limited and you determine that this is an example of ? Natal
dispersal because of resources competition
Which of the following is an example of wildlife migration? When songbirds move back
and forth predictably between a wintering habitat in the Caribbean and a breeding habitat in Ohio
The Nassau grouper is distributed in discrete patches of coral reef within the Caribbean Sea.
Researchers determine that grouper in reef A exhibit positive population growth rate, where as
grouper in reef B exhibit negative population growth rate. The reefs are of the same size, but reef
B was subject to extreme coral bleaching and is of much lower quality. Despite this, the Nassau
, grouper continues to persist within the ecosystem. What type of population best describes the
grouper? Source-Sink Metapopulation
t or f: If you were in an oak hardwood forest vs shortleaf pine forest the growth and yield of
these two forests would be the same if they were growing on similar site qualities. false
A local fishery manager has been collecting data on the biomass and birth and death rates of a
population of largemouth bass in Knox Lake in Ohio to determine whether the bass is currently
at its carrying capacity. Their data illustrate that over the last five year dN/dt is equal to (-0.75).
This means that population biomass is: Greater than Carrying Capacity
Which of the following is not a mechanism of animal dispersal? Use of seasonal
resources
Red knot populations that migrate from pole to pole each year have undergone rapid population
declines over the last decade. What has been identified as a key reason behind this decline?
The depletion of horseshoe crabs and loss of habitat in the Delaware Bay have limited the
vital refueling and resting location for the species along its migratory route
