BIO 322 Exam 1 Questions With Complete Solutions
Agencies in charge of enforcing the ESA Correct Answers
USFWS
Army Corps of Engineers Correct Answers management of
nation's waterways, including wetland and costal restoration
Calculate a population doubling time using the rule of 70.
Correct Answers divide 70 by the population growth rate, result
is the number of years required to double to population
Canada's Species at Risk Act Correct Answers allows the final
decision regarding species listing to be based on both scientific
and socioeconomic considerations
CITES Correct Answers international treaty that regulates the
global trade of selected species, bans trade of endangered
species and their products/body parts
Compare the IPAT equation and the Environmental Footprint as
measures of environmental impact. Correct Answers IPAT:
measures human footprint based on 3 factors (population,
affluence, technology), environmental footprint: the land area
needed for an individual or population to provide resources and
assimilate wastes
Compare the strengths and weaknesses of the biological,
morphological, and phylogenetic species concepts in relation to
species conservation. Correct Answers biological SC: no
viable/fertile offspring = not same species. (can't be applied to
, fossils, asexual reproducers, and gene flow between species
occuring in nature). morphological SC: look the same = same
species (can't identify cryptic species, morphological features
are subjective, ignores phenotypic variation). phylogenetic SC:
smallest group that shares a common ancestor (degree of
difference is subjective, phylogenetic relations are not
determined for all organisms).
concerns about protected areas Correct Answers 1. protected
areas vary significantly across nations
2. the reasons why protected areas are created are not always
focused on conservation value or biodiversity objectives
conservation easement Correct Answers a legal agreement that
financially rewards landowners in exchange for restrictions on
current and future land uses
conservation easements and conservation covenants are different
how? Correct Answers easements tend to be in perpetuity and
remain with the land when it changes hands, but covenants tend
to have a limited lifetime and often do not transfer to the new
owners when the land changes hands
Convention on Biological Diversity Correct Answers 1.
conservation of biodiversity
2. sustainable use of the components of biodiversity
3. fair and equitable sharing of the benefits arising from the
commercial and other uses of genetic resources
Date the US ESA was passed Correct Answers December 28th,
1973, Richard Nixon
