Answers Verified by Experts
Which of the following is not an example of an activity related to an extractive objective of a
fishery?
a. Restoration of coastal wetland habitat to provide more nursery grounds for larval walleye in
order to maintain the fishery now and in the future
b. Provide Petco with a supply of clownfish to sell
c. Supply a local restaurant in New Orleans with crayfish for Mardi Gras.
d. Employ the concept of maximum sustainable yield to the New England cod fishery.
Restoration of coastal wetland habitat to provide more nursery grounds for larval walleye
in order to maintain the fishery now and in the future.
What are impacts associated with aquaculture? Nutrient pollution from fish waste, release
of chemicals (e.g. antibiotics) from a fish hatchery into water bodies, transfer of parasites
between hatchery-raised fish and wild populations of fish
Eastern forests are dominated by: deciduous, or hardwood, species
,Western forests are dominated by: coniferous, or softwood, species
Which of the following is considered a non-renewable resource?
a. Timber
b. Wildlife
c. Coal Coal
The primary reason that half the wildlife species globally are declining is: Habitat loss
Managers of the Florida Keys ecosystem have become increasingly concerned with invasions of
the non-native lion fish. They have been continually monitoring and assessing the abundance and
growth rate of the population since its introduction and have found that currently nothing is
regulating the growth of this population. In this ecosystem, lion fish likely exhibit what type of
population growth? Exponential population growth
Lake Erie fisheries managers have been collecting data on the population dynamics of the yellow
perch for decades. Currently, they have determined that the population abundance is at its
carrying capacity for yellow perch. Based on that information, what is the relationship between
the birth and death rate of yellow perch at carrying capacity? Birth rate is equal to death
rate
,Wildlife management that is preventative or protective in order to allow ecological processes to
determine the dynamics of the system is what type of management? Custodial
Scientists estimate the maximum sustainable yield for the yellow perch fishery in Lake Erire to
be 1.60 million tons for 2015. Fisheries managers apply the Precautionary Principle to the yellow
perch fishery and decide that the maximum amount of yellow perch that should be harvested
from commercial fisheries is:
1.70, 1.65, 1.60, or 1.55 million tons 1.55 million tons
Tree growth habit that displays a single main stem with smaller lateral branches is referred to as:
Excurrent
Which term best describes the following observation? The desert pupfish lives in aquatic
environments that can reach as high as 105 degrees Fahrenheit. As a consequence, the body
temperature of the desert pupfish is approximately 105 degrees F. Ectothermic
Which individual is most responsible for the current trend of forest ownership in the US?
Gifford Pinchot
, Shade-intolerant tree species: Grow faster than shade-tolerant species, are shorter lived
than shade-tolerant species, and typically produce forests that are less diverse in structure
A riparian ecosystem is an example of: An inter-dependent system of aquatic and
terrestrial life
Once considered enigmatic, what has been revealed to be the most significant reason for the
recent global amphibian declines? Disease
The Public Trust Doctrine holds that wildlife are a public resource, managed for use by all, with
which of the following exclusions? Confined fish farms and forests on private property
_____________ refers to the number of individuals birthed or hatched within a specific period of
time, whereas _______________ refers to the number of individuals birthed or hatched in a
given year that survive to reproductive size. Natality, Recruitment
The Lagunitas River Coho fishery is an example of a paradigm shift with regards to a change in
fisheries objectives. Which seemingly contradictory pair of categories of objectives emerged to
priority following cancellation of the fishing season and subsequent restrictions on take?
Sustainability and Social
