Exam 21: A: Population Ecology on the Tracks of Wolves and Moose

Define carrying capacity.

An increase in the predator population that consumes herbivorous animals will cause

Which is NOT a result of climate change affecting the predator prey relationships of Isle Royale?

You are tasked with estimating the population size of three species of animals occurring in a national park.One occurs in a random distribution pattern,the second in a clumped pattern,and the third in a uniform pattern.Below,list the three,and for each one describe any problems you might encounter and how you would estimate population size given those problems and that pattern.Finally,comment on how accurate that estimate might be.

The term _______ describes all interacting species,such as moose,ticks,and wolves,as well as their surrounding environment of trees,vegetation,and climate.

The best example of exponential population growth would be an increase of _____ per generation.

A plant with wind-dispersed seeds is most likely to grow in a ____ distribution.

Which population distribution pattern is encountered most often by ecologists?

Which is NOT an abiotic factor that could affect a population?

Which of the following can be used to monitor the health of a wild animal?

Butterflies eat flower nectar and birds eat butterflies.The butterflies,flowers,and birds constitute a(n)

List at least 5 abiotic factors that shape an ecosystem.

All of the gray wolves found in Yellowstone Park constitute a _____.

Food abundance is an example of a(n)_________ factor that is also a density-__________ factor,and a hurricane is an example of a(n)________ factor that is density __________.

Which would NOT be examined in the study of a community?

The total number of wolves inhabiting Isle Royale is defined as a _____.

A few years after a predator species population increases,the ____.

The rate of natural increase approximates zero when carrying capacity is reached and

Which is a density-independent factor?

The term _______ describes the interacting populations (e.g.,moose and ticks)within an ecosystem.
