Environmental Science Chapter 6 Review Wild Species and Biodiversity

protection of biodiversity around the world requires

Basic science to guide public policies and laws that then must be funded and enforced

passed in 1900, the most significant domestic legislation to protect wildlife from illegal killing or sale is the

Lacey act

endemic species are

Limited to just one location, such as an island

legal hunters in the United States

Pay hunting fees that help manage the populations of their prey

The loss of biodiversity most severely affects

The poorest people in developing nations

One challenge to the protection of endangered animal species from overexploitation for commercial purposes, such as rhinoceros horns, is that as a species becomes increasingly rare,

The price of illegal animal products increases

recent events indicate that when permission for exemption from the CITES agreement is granted to allow the sale of legally collected ivory

The sale of poached ivory increases

ecotourism throughout the world relies upon

a widespread public interest in exploring and maintaining natural environment

invasive species have been

and ecological problem in North America since the first European colonists arrived

The greatest number relating to both known and yet to be discovered species are types of

animals

the ability of scientists to understand the natural relationships between organisms and their environments depends upon the

availability and preservation of undisturbed regions in the world

as of 2014, more than 20,000 species have been placed on the red list

because they are at high risk of extinction as determined by criteria similar to the criteria for designating endangered species in the United States

which of the following pairs includes concepts that are most closely associated to each other?

biological wealth and biodiversity

the search is on as the evidence from ethnobotany reveals the genetic potential of wild plants to produce chemicals of medical significance. the scientists exploring the medicinal use of plants by indigenous peoples throughout the world are engaged in

bioprospecting

according to the international union for concerned scientists in 2014, group showing highest extinction risk are

birds, amphibians, and freshwater fish

a taxonomist would be most helpful in

classifying and naming the number of insect species in a particular part of a rainforest

many conservationists support returning top predators such as wolves and panthers to areas where they have been exterminated. Although some re-introductions have been made, the practice is controversial because these animals are

considered by some ranchers to be a threat to livestock and humans

biodiversity in the world is

declining and is most negatively impacting the poorest people of the world

in general, biodiversity is

declining in the United States and around the world

A loss of plant biodiversity due to introduced invasive species will likely

decrease the amount of energy moving through the food chain

A poacher kills polar bears in Alaska and ships their skins to buyers in Asia. The poacher is most likely in violation of laws that come from the

endangered species act and CITES

among the goals of the UNEP supported convention on biological diversity are

equitable sharing of genetic resources within each nation

although unusually high, extinction rates may be

even higher because of the loss of tropical forests

The fragmentation of natural habitats in the conversion of land for human uses creates

habitat breaks that favor species that thrive at the edges of ecosystems

The acronym HIPPO identifies the five major factors contributing to extinction today. These are

habitat destruction, invasive species, pollution, population growth, and over exploitation

The endangered species act

has been subject to political pressures and now operates on year to year budget extensions

compared to the evolutionary long term historical average rate of extinction, extinction rates today are

higher

wild turkey populations in the United States have made a dramatic recovery in large part because of

hunting restrictions

The endangered species act

include species recovery plans intended to help listed species survive and thrive

species are most likely to be conserved by humans if they have

instrumental value

someone who argues that every species has a right to exist, undisturbed, on this planet is arguing for the

intrinsic value of life

The philosophy of the endangered species act primarily reflects

intrinsic values

which one of the following least represents ecosystem capital?

introduced species that change ecosystems

The great sunflower project

invites local citizen scientist to observe and document pollinators, which are in decline

human interactions between wildlife, homes, and highways

is an increasing problem as human populations increase and spread

domestic and feral house cats in the United States

kill more than 1 billion small mammals and birds annually

ultralight aircraft played an important part in the recovery of whooping cranes by

leading flocks of these birds on their seasonal migrations

which of the following would most likely have the greatest impact on a large ecosystem?

loss of several keystone species from the ecosystem

wild plants often have greater resistance to parasites than domesticated plants because the wild plants experience

natural selection, while domesticated plants experience artificial selection

biodiversity in extensive dead zones of both freshwater and marine ecosystems is mainly caused by pollution from

nitrogen and phosphorus nutrients used in agriculture

the greatest biodiversity would be in an ecosystem with the same number of species as other ecosystems but which has

no single dominant species

The critical ecosystem partnership fund provides money to

non-governmental agencies to protect biodiversity hotspots

when cultivars require adaptations not currently in their genetics, plant breeders

often introduce traits found in wild varieties of the plant

almost all of the threats to biodiversity represented by the acronym capital HIPPO are related to the

over population of the world by humans

only about 30 species have recovered significantly enough to be removed from the endangered species list. Recovery to this extent is limited because

populations are already low and at higher risk by the time they are listed

the main instrumental value of biological diversity is the

potential for new types of animals and plants that can be used by humans

the best way to sustainably manage natural environments is to

preserve and maintain the interactions between the members of the ecosystem

to best protect global biodiversity when purchasing a non-native species to keep as a pet, you should

purchase only captive bred species

wild turkeys, peregrine falcons, and snowy egrets are examples of birds that have

recovered significantly since gaining legal protection

ecosystem sustainability primarily results from the

relationships between the organisms in an ecosystem

which of the following organisms has the greatest instrumental value?

salmon

which one of the following is not a major source of invasive species in the world?

species escaping from zoos and animal parks

The convention on biological diversity is an international treaty

that aims to conserve biological diverse city worldwide but has not been ratified in the United States

which of the following best represents a loss of biological wealth?

the extinction of several beetle species

the world's wild species represent a warehouse of genetic diversity of instrumental value commonly called

the genetic bank

the structure, stability, and maintenance of all ecosystems results from the

the totality of all interactions of organisms in that ecosystem

the greatest potential for developing entirely new types of agricultural crops depends upon

thousands of plant species that occur only in the wild

which of the following ecosystems might be considered as a bank of biodiversity?

tropical forests

plants that can best resist a variety of environmental challenges are most likely

wild plants with high degrees of variation

in the United States today,

wildlife is a public resource and not the property of private landowners
