    Wildlife has value in which of the following ways:

    • Material, spiritual, economic

    • Scientific, economic

    • Ecological, scientific, spiritual

    • Intrinsic, ecological, economic

    • Ecological, spiritual, material, intrinsic, economic, scientific

    Correct Answer
    A. Ecological, spiritual, material, intrinsic, economic, scientific
    Explanation
    Wildlife has ecological value because it plays a crucial role in maintaining the balance of ecosystems. It has spiritual value as it is often revered and considered sacred in many cultures. Wildlife also has material value as it provides resources such as food, medicine, and materials for clothing and shelter. Additionally, wildlife has intrinsic value, meaning it has inherent worth and should be protected for its own sake. Furthermore, wildlife has economic value as it contributes to tourism, recreation, and the economy through activities such as wildlife watching and hunting. Finally, wildlife has scientific value as studying it helps us understand and advance our knowledge of the natural world.

    Which of the following is not a part of Adaptive Resource Management?

    • Acknowledging incomplete knowledge of ecosystems

    • Doing management as an "experiment"

    • A linear management process

    • Monitoring

    • None of the above

    Correct Answer
    A. A linear management process
    Explanation
    Adaptive Resource Management involves acknowledging incomplete knowledge of ecosystems, doing management as an "experiment," and monitoring. A linear management process, on the other hand, does not align with the adaptive approach. Instead of following a linear step-by-step process, Adaptive Resource Management emphasizes flexibility, learning, and adjusting management strategies based on new information and feedback.

    Wildlife management can be financed in part by:

    • Sales tax

    • License plate sales

    • Income tax check offs

    • Excise taxes

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Wildlife management can be financed through various means, including sales tax, license plate sales, income tax check-offs, and excise taxes. Sales tax on items related to wildlife, such as hunting and fishing equipment, can contribute to funding wildlife management initiatives. License plate sales with wildlife-themed designs can also generate revenue for conservation efforts. Income tax check-offs allow individuals to voluntarily contribute a portion of their tax refunds towards wildlife management. Additionally, excise taxes on items like firearms and ammunition can provide funding for wildlife conservation programs. Therefore, all of the mentioned options can be utilized to finance wildlife management.

    What contributed to the extinction of the passenger pigeon?

    • Railroads and telegraphs

    • Fragmentation of pine forest in the Southeast

    • Breeding in small groups

    • Poor flying ability

    • None of the above

    Correct Answer
    A. Railroads and telegraphs
    Explanation
    The extinction of the passenger pigeon was contributed to by the presence of railroads and telegraphs. These advancements in transportation and communication allowed for the efficient hunting and capturing of large numbers of passenger pigeons. The birds were sought after for their meat and feathers, and the ease of transportation made it possible to exploit them on a massive scale. This, combined with habitat loss and overhunting, led to the rapid decline and eventual extinction of the passenger pigeon.

    Which of the following species is extinct?

    • Heath hen

    • Carolina parakeet

    • Stellar's sea cow

    • Labrador duck

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the species mentioned in the options, namely the heath hen, Carolina parakeet, Stellar's sea cow, and Labrador duck, are extinct. This means that these species no longer exist in the world. Extinction occurs when a species dies out completely, usually due to factors such as habitat loss, hunting, or environmental changes. In the case of these four species, they were unable to adapt to changing conditions or faced intense human pressures, leading to their extinction.

    Rate this question:

  • 11. 

    A common theme for species that become extinct could involve:

    • Introduced species

    • Distribution confined to islands

    • Habitat loss

    • Over exploitation

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "all of the above" because all of the listed factors - introduced species, distribution confined to islands, habitat loss, and overexploitation - have been identified as common themes for species becoming extinct. Introduced species can disrupt ecosystems and outcompete native species, leading to their extinction. Species confined to islands are often more vulnerable to extinction due to their limited range and susceptibility to environmental changes. Habitat loss, caused by factors such as deforestation or urbanization, can destroy the homes and food sources of species. Overexploitation, such as hunting or fishing beyond sustainable levels, can also drive species to extinction.

    Bounties as a means to control overabundant or unwanted wildlife

    • Are effective.

    • Tend to encourage removing only the "annual surplus."

    • Are no longer used as a management strategy.

    • Are a cheap and easy to administer wildlife management strategy.

    • None of the above

    Correct Answer
    A. Tend to encourage removing only the "annual surplus."
    Explanation
    Bounties as a means to control overabundant or unwanted wildlife tend to encourage removing only the "annual surplus." This means that bounties are implemented to target and remove only the excess population of wildlife that is causing problems, rather than eliminating the entire population. This approach helps in maintaining a balance in the ecosystem by controlling the population size without completely wiping out the species.

    Which of the following is not an exotic species currently living in North Carolina?

    • Brown trout

    • House sparrow

    • Mute swan

    • Brown tree snake

    • None of the above

    Correct Answer
    A. Brown tree snake
    Explanation
    The brown tree snake is not an exotic species currently living in North Carolina. This is because the brown tree snake is native to the islands of the western Pacific Ocean, such as Guam and Papua New Guinea, and is not found in North Carolina. The other options listed (brown trout, house sparrow, and mute swan) are all exotic species that have been introduced to North Carolina and are currently living there.

    Which of the following is not true of bison in the Greater Yellowstone Ecosystem?

    • In the late 1960's the population was allowed to "fluctuate naturally" and grew from about 400 to about 3,500 over the next few decades.

    • They care brucellosis, which is a concern for cattle ranches in Montana.

    • They make up a majority of the prey items of wolves.

    • Bison wandering outside Yellowstone Park can be killed.

    • None of the above

    Correct Answer
    A. They make up a majority of the prey items of wolves.
    Explanation
    The given answer states that bison make up a majority of the prey items of wolves, which is not true. While bison are indeed a prey species for wolves, they do not make up a majority of their prey items. Wolves in the Greater Yellowstone Ecosystem have a diverse diet that includes other ungulates such as elk and deer, as well as smaller mammals. Therefore, the statement is incorrect.

    Lead availability to wildlife can depend on

    • Hunting and fishing pressure

    • Water chemistry

    • Substrate texture

    • Cultivation

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The availability of lead to wildlife can depend on various factors. Hunting and fishing pressure can contribute to lead exposure as lead ammunition and fishing sinkers can be ingested by animals. Water chemistry plays a role as certain conditions can cause lead to leach into the water, making it accessible to wildlife. Substrate texture can also affect lead availability, as animals may come into contact with lead-contaminated soil or sediment. Finally, cultivation practices can introduce lead into the environment, potentially impacting wildlife. Therefore, all of the mentioned factors can influence lead availability to wildlife.

    Lead poisoning of wildlife is mainly a problem for

    • Fish

    • Reptiles

    • Mammals

    • Waterfowl

    • All of the above

    Correct Answer
    A. Waterfowl
    Explanation
    Lead poisoning is mainly a problem for waterfowl because they are often exposed to lead through ingestion of lead shot or fishing sinkers. Waterfowl, such as ducks and geese, frequently feed in wetlands and shallow waters where lead ammunition and fishing tackle may be present. When waterfowl ingest lead, it can lead to severe health issues and even death. Other wildlife species like fish, reptiles, and mammals may also be affected by lead poisoning, but waterfowl are particularly vulnerable due to their feeding habits and habitat preferences.

    Rate this question:

  • 18. 

    Although lead shot was banned in the U.S. and Canada by 1999, many sportsmen and manufacturers were against the ban because they feared that

    • Shotgun shells would be prohibitively expensive

    • A and C

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "all of the above". This means that all of the reasons mentioned in the options were concerns of sportsmen and manufacturers regarding the ban on lead shot. They feared that gun barrels would be damaged, crippling losses would be greater, and shotgun shells would become prohibitively expensive.

    Recovery of wood ducks in the Southeast involved which of the following:

    • Increased restrictions on hunting

    • More flooded woodlands concomitant with an increase in beaver populations

    • Wide-spread installation of next boxes

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
    Explanation
    The recovery of wood ducks in the Southeast involved all of the above options. Increased restrictions on hunting helped protect the wood duck population from overharvesting. More flooded woodlands, which were created by an increase in beaver populations, provided suitable habitat for wood ducks. The wide-spread installation of nest boxes also played a role in the recovery by providing additional nesting sites for wood ducks.

    • There are about 2,500 gray wolves in Minnesota

    • Alaska has thousands of gray wolves

    • North Carolina has about 100 gray wolves

    Correct Answer
    A. North Carolina has about 100 gray wolves
    Explanation
    The statement "North Carolina has about 100 gray wolves" is not true because North Carolina does not have a population of gray wolves. Gray wolves are not native to North Carolina and are not found in the state.

    The process of energy transfer between trophic levels

    • Is only about 10% efficient

    • Implies there are fewer carnivores than herbivores in the Serengeti

    • Implies there cannot be a lot of top level carnivores

    • Implies the length of the food chain is limited

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "all of the above." The statement "The process of energy transfer between trophic levels is only about 10% efficient" implies that energy is lost as it moves up the food chain, resulting in fewer organisms being able to be supported at higher trophic levels. This, in turn, suggests that there would be fewer carnivores than herbivores in the Serengeti, as there is less energy available to sustain them. Additionally, the limited energy transfer implies that there cannot be a lot of top-level carnivores, as there would not be enough energy available to support a large population. Finally, the inefficiency of energy transfer also implies that the length of the food chain is limited, as there is not enough energy to support a long chain of organisms.

    Beavers have a narrow thermoneutral zone because

    • They are a large rodent

    • They are semi aquatic and can modify their environment

    • They transfer plant energy to beaver biomass more efficiently than most herbivores

    • They are like sea otters and have little fat to insulate them

    • None of the above

    Correct Answer
    A. They are semi aquatic and can modify their environment
    Explanation
    Beavers have a narrow thermoneutral zone because they are semi-aquatic and can modify their environment. This means that beavers are able to regulate their body temperature by modifying their surroundings, such as building dams and lodges. By creating these structures, beavers are able to create a stable and warmer environment, even during colder temperatures. This allows them to conserve energy and maintain a narrow thermoneutral zone.

    The Intermediate Disturbance Hypothesis states:

    • Animal abundance is greatest at an intermediate level of disturbance

    • Animal biomass is greatest at an intermediate level of disturbance

    • Species diversity is greatest at an intermediate level of disturbance

    • R-selected species dominate

    • K-selected species dominate

    Correct Answer
    A. Species diversity is greatest at an intermediate level of disturbance
    Explanation
    The Intermediate Disturbance Hypothesis suggests that species diversity is greatest at an intermediate level of disturbance. This means that when disturbance levels are too low, only a few dominant species may be able to thrive and outcompete others. On the other hand, when disturbance levels are too high, only a few highly adapted and resilient species may be able to survive. However, at an intermediate level of disturbance, a wider range of species can coexist, as there is a balance between competitive exclusion and the creation of new niches. This leads to a higher overall species diversity.

    • Equilibrium stability

    • Resilience

    • Resistance

    • All the above

    • None of the above

    Correct Answer
    A. All the above
    Explanation
    Stability in ecosystems can be thought of in terms of equilibrium stability, which refers to the ability of an ecosystem to maintain a relatively constant state over time. It can also be thought of in terms of resilience, which is the ability of an ecosystem to recover and adapt following disturbances. Additionally, stability can be associated with resistance, which is the ability of an ecosystem to withstand and minimize the impact of disturbances. Therefore, all of the given options - equilibrium stability, resilience, and resistance - contribute to the overall stability of ecosystems.

    A population is growing exponentially when

    • The per capita rate of growth is a constant percentage

    • The growth rate is 22%

    • The growth rate is an ever increasing rate per unit of time

    • All the above

    • Non of the above

    Correct Answer
    A. All the above
    Explanation
    The given answer "all the above" is correct because exponential growth occurs when the per capita rate of growth is a constant percentage, which means that the growth rate remains constant over time. Additionally, exponential growth can also occur when the growth rate is a fixed percentage, such as 22%. Lastly, exponential growth can occur when the growth rate is an ever-increasing rate per unit of time, which means that the growth rate itself is increasing over time. Therefore, all of the given options accurately describe the conditions for exponential growth.

    The maximum intrinsic growth rate (rm)

    • Is greater for elephants than mice

    • Is greater for mice than elephants

    • Is the same for all species

    • Depends on the weather

    • None of the above

    Correct Answer
    A. Is greater for mice than elephants
    Explanation
    The correct answer is "is greater for mice than elephants." This is because mice have a higher maximum intrinsic growth rate compared to elephants. Intrinsic growth rate refers to the maximum rate at which a population can grow under ideal conditions, without any limiting factors. Mice have a shorter lifespan and reach sexual maturity at a younger age compared to elephants, allowing them to reproduce more frequently and have a higher population growth rate. Elephants, on the other hand, have a longer gestation period and produce fewer offspring, resulting in a lower intrinsic growth rate.

    When a few deer were introduced into previously unoccupied but excellent deer habitat on the George Reserve, over the first few years the deer population

    • Erupted.

    • Grew at nearly an exponential rate

    • Grew logistically

    • Grew sigmoidally

    • All the above

    Correct Answer
    A. Grew at nearly an exponential rate
    Explanation
    The correct answer is "grew at nearly an exponential rate." This is because when a few deer were introduced into previously unoccupied but excellent deer habitat, the population experienced rapid growth. The term "nearly exponential rate" suggests that the population growth was very fast, similar to exponential growth, but not exactly following an exponential pattern.

    Rate this question:

  • 32. 

    For the logistic growth model when the population

    • Is small, it is growing at nearly an exponential rate

    • Is near carrying capacity, it is not growing

    • Is about 1/2 carrying capacity, recruitment is near its maximum

    • All the above

    • None of the above

    Correct Answer
    A. All the above
    Explanation
    The logistic growth model describes how a population grows over time. When the population is small, it is growing at nearly an exponential rate because there are plenty of resources available for individuals to reproduce and survive. As the population approaches its carrying capacity, it stops growing because the available resources become limited. When the population is about half of the carrying capacity, recruitment (the number of new individuals joining the population) is near its maximum because there are still plenty of resources available but competition is increasing. Therefore, all of the statements mentioned in the answer are correct explanations for different stages of population growth in the logistic growth model.

    Rate this question:

  • 33. 

    At the inflection point (I) in a population growth model exhibiting sigmoid population growth

    • The slope of the SY curve switches from positive to negative

    • The slope of the SY curve switches from negative to positive

    • Is where per capita growth is near zero

    • Is the carrying capacity

    • None of the above

    Correct Answer
    A. The slope of the SY curve switches from positive to negative
    Explanation
    At the inflection point in a sigmoid population growth model, the slope of the SY curve switches from positive to negative. This is because the inflection point represents the point of maximum growth rate in the population. Before the inflection point, the population is growing at an increasing rate, resulting in a positive slope. After the inflection point, the population growth rate starts to decrease, leading to a negative slope. Therefore, the inflection point marks the transition from positive to negative slope in the SY curve.

    The fundamental relationship that underlies sigmoid population growth is:  as N increases, per capita growth

    • Increases

    • Decreases

    • Decreases, then increases

    • Increases, then decreases

    • None of the above

    Correct Answer
    A. Decreases
    Explanation
    As the population size (N) increases, the per capita growth rate decreases. This means that as the population gets larger, each individual has less access to resources and space, leading to a decrease in their growth rate. This is a fundamental relationship in sigmoid population growth, where the growth initially accelerates but eventually slows down as the population approaches its carrying capacity.

    Rate this question:

  • 35. 

    In sigmoid growth, the sustained yield curve is

    • Bell shaped

    • Sigmoid shaped

    • Dome or hump shaped

    • Is a straight line with negative slope

    • None of the above

    Correct Answer
    A. Dome or hump shaped
    Explanation
    The sustained yield curve in sigmoid growth is dome or hump shaped. This means that initially, the growth rate is slow, then it accelerates rapidly, and finally, it slows down again. This pattern resembles a curve that starts low, rises to a peak, and then declines. This shape is characteristic of sigmoid growth, where the population or yield initially grows slowly, then experiences rapid growth, and eventually levels off as it reaches carrying capacity or maximum sustainable yield.

    Rate this question:

  • 36. 

    For the logistic growth model, population size on right side of the inflection point on a sustained yield curve is considered relatively stable because

    • Of a positive feedback between the number of recruits (R) and N

    • Of a negative feedback between the number of recruits (R) and N

    • The population is growing at the maximum intrinsic rate

    • All the above

    • None of the above

    Correct Answer
    A. Of a negative feedback between the number of recruits (R) and N
    Explanation
    The correct answer is "of a negative feedback between the number of recruits (R) and N." In the logistic growth model, the population size on the right side of the inflection point on a sustained yield curve is considered relatively stable because there is a negative feedback between the number of recruits (R) and the population size (N). This means that as the population size increases, the number of recruits decreases, which helps to regulate and stabilize the population growth. This negative feedback mechanism prevents the population from growing at an unsustainable rate and helps maintain a relatively stable population size.

    Population models are valuable in wildlife management because they

    • Help point out what data are needed

    • Require thinking conceptually about populations

    • Can be used to assess management alternatives

    • All the above

    • None of the above

    Correct Answer
    A. All the above
    Explanation
    Population models are valuable in wildlife management because they help point out what data are needed, require thinking conceptually about populations, and can be used to assess management alternatives. By using population models, wildlife managers can identify the necessary data to collect in order to make informed decisions about population management. These models also require managers to think critically and conceptually about how populations function and interact with their environment. Additionally, population models allow managers to assess different management strategies and alternatives to determine their potential impact on the population. Therefore, all of the given options are correct explanations for why population models are valuable in wildlife management.

    For a population index to be of value in comparisons over time or space,

    • Observability must be known

    • Observability can be unknown, but must be constant

    • Observability is really not an issue

    • Observability must be different or else a comparison is not possible

    • All the above

    Correct Answer
    A. Observability can be unknown, but must be constant
    Explanation
    In order for a population index to be useful for comparisons over time or space, it is important that the observability of the index remains constant, even if the exact value is unknown. This means that the factors being measured and the methods of measurement should remain consistent, allowing for meaningful comparisons to be made. While observability being known or different may also be important in certain cases, the key requirement is that it remains constant.

    Metapopulations are characterized by

    • Subpopulations of various sizes somewhat isolated from one another

    • Genetic exchange within subpopulations that is greater than that between subpopulations

    • Some subpopulations that can wink in and out of existence

    • Dispersal and recolonization among subpopulations

    • All the above

    Correct Answer
    A. All the above
    Explanation
    Metapopulations are characterized by subpopulations of various sizes that are somewhat isolated from one another. This means that the subpopulations are not completely connected and can have limited gene flow between them. Additionally, genetic exchange within subpopulations is usually greater than that between subpopulations, indicating that individuals within a subpopulation are more likely to mate with each other. Some subpopulations can wink in and out of existence, meaning that they can go extinct and then be recolonized. Finally, dispersal and recolonization among subpopulations is a key characteristic of metapopulations, as individuals move between different subpopulations to maintain genetic diversity and prevent inbreeding. Therefore, all of the above statements accurately describe the characteristics of metapopulations.

    An explanation for the decline of black ducks is:

    • A reduction of forests in the East has contributed to the mallard population expanding eastward

    • Black duck females will readily pair with mallard males on the wintering grounds

    • Mallards seem to be more tolerant of human disturbance than are black ducks

    • Loss of forested wetlands in the East has reduced breeding habitat for black ducks

    • All the above

    Correct Answer
    A. All the above
    Explanation
    The decline of black ducks can be attributed to multiple factors. Firstly, the reduction of forests in the East has led to an expansion of the mallard population towards the east, potentially competing with black ducks for resources. Additionally, black duck females readily pair with mallard males on the wintering grounds, which could lead to hybridization and a decrease in pure black duck populations. Furthermore, mallards have shown greater tolerance towards human disturbance compared to black ducks, which may give them a competitive advantage in human-altered environments. Lastly, the loss of forested wetlands in the East has resulted in a reduction of breeding habitat for black ducks.

    A function of territoriality in wild animals is to

    • Advertise for females

    • Minimize fighting for high quality habitat

    • Symbolize "my property, no trespassing"

    • All the above

    • None of the above

    Correct Answer
    A. All the above
    Explanation
    Territoriality in wild animals serves multiple purposes. Firstly, it allows animals to advertise for females, indicating their presence and availability for mating. Secondly, it helps minimize fighting among animals for high-quality habitat, as each individual establishes and defends its own territory. Lastly, territorial behavior symbolizes ownership and acts as a warning to other animals to stay away, indicating "my property, no trespassing." Therefore, all of the given options - advertise for females, minimize fighting for high-quality habitat, and symbolize "my property, no trespassing" - are correct explanations for the function of territoriality in wild animals.

    Dispersal in wild animals involves:

    • Emigration, because most animals disperse from their natal range

    • Migration, because it is a permanent movement

    • Immigration, because it's what moves into a population that's important

    • A and C

    • None of the above

    Correct Answer
    A. A and C
    Explanation
    Dispersal in wild animals involves emigration, as most animals disperse from their natal range, and immigration, as what moves into a population is also important. This means that animals leave their birthplace (emigration) and move into new areas (immigration), which helps to maintain genetic diversity and colonize new habitats.

    Imprinting

    • Was discovered by Eugene Odum

    • Is an interesting, but uncommon, behavior among wild species

    • Is phase sensitive learning

    • Is displayed mostly by adult animals, and rarely buy young animals

    • All the above

    Correct Answer
    A. Is phase sensitive learning
    Explanation
    Imprinting is a behavior that was discovered by Eugene Odum. It is an interesting but uncommon behavior among wild species. Imprinting is a form of phase-sensitive learning, which means it occurs during a specific period in an animal's development. It is mostly displayed by adult animals and rarely by young animals. Therefore, the correct answer is that imprinting is phase sensitive learning.

    Brown-headed cowbirds

    • Evolved brood parasitism in conjunction with Eastern forest birds

    • Show some evidence of a "Mafia-like" retaliatory behavior by destroying the nest of a potential host that previously rejected a cowbird egg

    • Are not brood parasites

    • All the above

    • None of the above

    Correct Answer
    A. Show some evidence of a "Mafia-like" retaliatory behavior by destroying the nest of a potential host that previously rejected a cowbird egg
    Explanation
    The correct answer is "show some evidence of a 'Mafia-like' retaliatory behavior by destroying the nest of a potential host that previously rejected a cowbird egg." This suggests that brown-headed cowbirds exhibit a behavior similar to the Mafia, where they retaliate against potential hosts that reject their eggs by destroying their nests. This behavior supports the idea that brown-headed cowbirds have evolved brood parasitism in conjunction with Eastern forest birds.

    Loss of stopover habitat could be an important factor contributing to the decline in Neotropical migratory birds.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Loss of stopover habitat refers to the destruction or degradation of the areas where migratory birds rest and refuel during their long-distance journeys. These stopover sites are crucial for the birds' survival and successful migration. If these habitats are lost, the migratory birds may not have enough resources to complete their journey or may face increased predation risks. Therefore, the decline in Neotropical migratory birds can indeed be attributed to the loss of stopover habitat, making the statement true.

    In general, neither prairie birds nor eastern woodland birds have evolved defenses to Brown-headed cowbirds.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because prairie birds have evolved defenses against Brown-headed cowbirds. Prairie birds recognize and reject cowbird eggs from their nests, preventing the cowbirds from parasitizing their nests. This behavior has evolved as a defense mechanism to protect their own eggs and offspring from being outcompeted by the cowbird chicks. Therefore, it is incorrect to say that neither prairie birds nor eastern woodland birds have evolved defenses to Brown-headed cowbirds.

    Beavers are an example of a precocial animal that is nidifugous.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Beavers are not an example of a precocial animal that is nidifugous. Precocial animals are born in an advanced state and are able to move around and feed themselves shortly after birth, while nidifugous animals leave the nest or burrow shortly after hatching or birth. Beavers, on the other hand, are altricial animals, meaning they are born in a helpless state and require care and feeding from their parents. Therefore, the given statement is false.
