Instrumental values of biodiversity can be categorized into all categories EXCEPT
religious or ethical
provisioning
cultural
regulating
In which biogeographic region do we see fewer biodiversity hotspots?
Indomalayan
Neotropical
Nearctic
Palearctic
Economic benefits of preserving biodiversity include all EXCEPT
Providing Products
Nutrient Cycling
Recreation
Moral Imperative
Economic benefits of preserving biodiversity include
nutrient cycling and recreation only
nutrient cycling, recreation, and providing products
recreation and providing products only
nutrient cycling and providing products only
The intrinsic value of an ecosystem
considers the value of an ecosystem apart from any economic benefit
considers the value an ecosystem provides in regulating natural systems
includes the cultural value of an ecosystem to its human inhabitants
is the monetary value of all species in the ecosystem
What factors can be used to identify biodiversity hotspots instead of species richness
number of endemic plant and animal species
number of endemic plant and animal species and percent extinct
number of endemic plant species and amount of vegetation loss
number of endemic animal species and genetic diversity of the species
The Svalbard Global Seed Vault in Norway is
an attempt to preserve genetic diversity of plant varieties for the fututre
a facility under the auspices of the United Nations that provides seed stock to developing nations annually
is a facility collecting seeds from northern latitudes to be preserved and used when agriculturally productive lands shift to these more northern latitudes with climate change
an experimental facility that attempts to grow plants under extreme conditions to model potential changes associated with global climate change
According to the IUCN, and based on percentages of known species, which types of animals have the highest percentage of species that are of least concern (not likely to be threatened in the future)?
birds and reptiles
birds and mammals
reptiles and amphibians
birds and fish
Based on North American fossil records of mammals, researchers were able to show that species richness for mammals in North America
fluctuated after the arrival of humans
was lower after the arrival of humans
was the same before and after the arrival of humans
was higher after the arrival of humans
The extinction rate of mammals during the course of the last 500 years is
the same as extinction rate of mammals over any other 500 year interval in the historical past
unable to be compared to the historical past, which causes grave concern for conservation biologists because they fear a sixth mass extinction
greater than the extinction rate of mammals over any other 500 year interval in the historical past
less than the extinction rate of mammals over any other 500 year interval in the historical past
Why is it important to preserve genetic diversity as well as species diversity?
high genetic diversity increases survival in changing environmental conditions
increased genetic diversity reduces the need for other related species in an ecosystem
lower genetic diversity decreases ecosystem functions
low genetic diversity can increase ecosystem stability
What rate of extinction will determine if the current rate of extinction is equivalent to a mass extinction?
45%
35%
65%
75%
Evidence exists that global climate change has caused all of the following EXCEPT
changes in breeding times for some species of birds and amphibians
a decline in ice mass in Greenland and Antartica
an increase in the average temperature of the planet
widespread extinction of species
In terms of potential loss of biodiversity, biomagnifiable chemicals tend to impact
all trophic levels equally
only those species found at multiple trophic levels
lower trophic levels more than higher trophic levels
higher trophic levels more than lower trophic levels
The observation that many of the same plant species are found in more places around the globe than they were in the past, changing the historic species composition, is testament to the idea that ______ is occurring
introduction equilibration
compositional balance
species moderation
biotic homogenization
The collapse of the Atlantic cod fishery can be attributed to some extent to
new technologies employed by the fishing industry
global climate change altering ocean water temperature and acidity
changes in the Grand Banks food web due to introduced species
increased demand of Atlantic cod by the public, particularly in Asian markets
In the lower 48 states of the US, wetlands once covered more that twice the area that they do today. One of the primary reasons for this decline in wetland coverage has been
redirection of river flows for navigational purposes
changes in precipitation patterns
climate change
drainage for agricultural reasons
Why do we need to consider the process of biomagnification when assessing the risk of a pesticide to wildlife?
It increases risk for producer species
It increases risk in scavenger species
It increases risk in species at the top of the food chain
it increases risk in aquatic species
What is NOT a way introduced species contribute to the extinction of native species?
competing better than native species
increasing the fitness of a competing native species
acting as a predator
acting as a pathogen on native species
What is NOT evidence that humans have historically contributed to extinction through overharvesting?
changes in species composition of forests after logging
the collapse of many ocean fisheries after extended fishing
the extinction of flightless bird species after encountering humans
bones of consumed animals changing over time from easy-to-catch species to hard-to-catch species
The reintroduction of wolves into the Greater Yellowstone Ecosystem has shown that
reintroductions of large carnivores do not work
a single species can have a dramatic effect on an entire ecosystem
reintroductions of upper trophic level species are only marginally successful, and the reintroduced species will remain endangered, due largely to lost ecosystem services unable to be restored
the instrumental values of such a species introduction are unable to be quantified
Globally, over the last 40 to 50 years, the amount of habitat protected has
increased in marine areas, but decreased in terrestrial areas
increased in terrestrial areas, but decreased in marine areas
increased in both terrestrial and marine areas
decreased in both terrestrial and marine areas
The habitat preserved for a minimum viable population of a species must be large enough so that population can persist, and should also be divided or distributed for what reason?
to allow for future speciation
to prevent the potential spread of disease from one subpopulation to another
to decrease intraspecific competition
to provide for greater variety of resource acquisition
Ecotourism is a value of biodiversity in which instrumental value category?
regulating
provisioning
supporting
cultural
When considering a species reintroduction, what is NOT a challenge that might arise?
high monetary cost
local opposition to the species
captive breeding programs' lack of success
changes in land use
What challenges can arise when considering a species reintroduction?
local opposition to the species and changes in land use only
high monetary cost, local opposition to the species, and changes in land use
high monetary cost and changes in land use only
high monetary cost and local opposition to the species only
