ECOL 111 Section B Questions and
Answers Graded A+
what is a r reproductive strategy and its purpose - Correct answer-"r" selected
species produce a large number of offspring in order to disperse widely in
unpredictable environments
what is a k reproductive strategy - Correct answer-"K" selected species invest all of
there resources in a small number of offspring that are more likely to survive in
predictable environments
What is allelopatric species - Correct answer-when a species is separated and
isolated from one another into two different groups
Benefits of tag recapture - Correct answer-Whole population estimate is possible
Can be used on open or closed populations
Difference between natural and artificial tagging - Correct answer-Natural tagging
is recognising animals by their patterns
Artificial tags are physically attached to animal

, Examples of remote sensing and tracking - Correct answer-Planes, satellite and
drones
what are the primary drivers of population change - Correct answer-Vital rates:
birth, death and movement
Malthusian growth model v Exponential model - Correct answer-Malthusian -
based on mechanism for change
Exponential - describe population growth in an unlimited environment
emigration and immigration - Correct answer-movement of individuals among
subpopulations
what determines a simple v complex life story - Correct answer-simple - migration
complex - dispersal stages
different types of age structures and how to draw them - Correct answer-rapid,
slow and zero growth
Three contrasting fertility curves - Correct answer-Fish - increase, large fish
produce more eggs
Songbirds - reach age and maturity then level off
Humans - not typical fecundity curve, go through menopause
