Exam Questions and CORRECT Answers
Wildlife and Fisheries - CORRECT ANSWER - Species or systems that involve
consumptive and non-consumptive use by humans
Wildlife - CORRECT ANSWER - All free living animals
Fisheries - CORRECT ANSWER - system that includes the fish, habitat and human users
Fish:single species
Fishes: multiple species
Management - CORRECT ANSWER - Manipulation of pop. or habits to achieve specific
goals or endpoint
Manipulative management - CORRECT ANSWER - Acting on a pop., changing numbers
by direct means or influencing numbers by indirect means
ex. altering food supply, habitat
Custodial management - CORRECT ANSWER - Preventative or protective, minimize
external influence on pop. and habitat
Life-history - CORRECT ANSWER - Traits that describe the life cycle of an organism
ex. birth, death, reproduction., # of offspring
Conservation - CORRECT ANSWER - sustainable management and use of natural
resources
Preservation - CORRECT ANSWER - leaving natural systems or resources as they are
,basic unit of management - CORRECT ANSWER - the population, NOT the individual
Dynamic management - CORRECT ANSWER - art of making land or aquatic habitat
produce a sustained harvest of wildlife or fish
Ecosystem management goals - CORRECT ANSWER - - new more
holistic/comprehensive approach to conservation of biodiversity
- keep everyone on the same page
- designed to integrate ecology, socioeconomic and institutional perspective
Adaptive resources management - CORRECT ANSWER - flexible to unanticipated and
complex outcomes, continual reassessment and innovation
Adaptive management - CORRECT ANSWER - Type of natural resources management
that implies making decisions as part of an ongoing process
Communities - CORRECT ANSWER - Interacting assemblage of living organisms in an
area; often divided by plant and animal
origin of community ecology - CORRECT ANSWER - Stephen Forbes (1844-1930)
Community ecology - CORRECT ANSWER - oldest discipline in ecology, importance of
interspecific interactions in descriptive natural history
intraspecific competition - CORRECT ANSWER - competition between members of the
same species
interspecific competition - CORRECT ANSWER - competition between members of
different species
, Indirect Competition - CORRECT ANSWER - consumption of a shared resource
Direct Competition - CORRECT ANSWER - interference or contest competition;
organisms prevent access or harm one another while seeking a resource
Population - CORRECT ANSWER - group of org. of the same species that occupy a
space, close enough to find and reproduce
Importance of population - CORRECT ANSWER - - how much can be harvested
- env. changes affect pop.
- predict when and why pop. goes extinct/endangered
- how pop affect eachother
- env. quality indicator
Population ecology issues - CORRECT ANSWER - - small/declining pop.

Exponential growth - CORRECT ANSWER - dN/dT=rN
dN: Change in #
dT: change in time
r: exp. growth rate or pop. determined by # of young and survival rate
N: pop. size @ any moment
Exponential growth: non-overlapping generations - CORRECT ANSWER - N=Ro^+ No
