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
