This is the length (in years) of the snowshoe hare population cycle, which is driven by predator/prey relationships.
What is 10 years?
100
This describes the link between the snowshoe hare and the Canadian lynx?
What is a predator/prey relationship?
100
Researchers observed the survival of Chtamalus
Just in areas with only their species
or
In areas with only their species and in areas with both Chthamalas stellatus and Balanus.
What is in areas with only their species and in areas with both Chthamalas stellatus and Balanus?
They observed how Balanus affected their survival over the course of a year.

This is the article that this graph relates to.
What is "Impact of Food and Predation on the Snowshoe Hare Cycle"?
(points for describing the right article, title does not need to be correct)
200
These factors were manipulated to determine to investigate the causes of the snowshoe hare population cycle.
What are food and predation?
Bonus: Plant nutrients were also added to increase plant growth, but did not affect hare population.

Regarding the results of the Population Regulation in Snowshoe hare and Canadian lynx, this answer is correct... (choose the correct answer below)
snowshoe hares are regulated from the top and bottom, while the lynx are regulated from below solely by the snowshoe hare
or
snowshoe hares are regulated from the middle, while the lynx are regulated from above solely by the snowshoe hare
What is snowshoe hares are regulated from the top and bottom, while the lynx are regulated from below solely by the snowshoe hare?
200
In these conditions were higher mortality rates observed for Chthamalus stellatus.
When Chthamalus stellatus were independent in an area
or
When Chthamalus stellatus and Balanus were present
What are conditions where Chthamalus stellatus and Balanus were present?
Because Balanus wouth smother and crush the Chthamalus.
200
These are the two species depicted on this graph.
Bonus if you name which is A and which is B.
Snowshoe hares and Canadian lynx.
A. Snowshoe hares
B. Canadian lynx

This is how long researchers tracked the number of hares living in the treated areas compared to control areas.
What are 8 years?
300
This is the meaning of a two-dimensional or three-dimensional cycle.
What is two-dimensional cycle means the population is affected by just one factor, and three-dimensional cycle means the population is affected by two variables?
300
This is one of the variables analyzed in the Chtamalus stellatus experiment.
4 possible answers
What are survival rates?
What is population density?
What is predation?
What are size and reproductive efficiency?
300
This is an important reason for predator/prey relationships supported by all three articles.
What is maintaining the balance of communities and ecosystems?
(variety of answers will be accepted)
400
This is how long researchers tracked the number of hares living in the treated areas compared to control areas.
What are 8 years?
400
These were the conclusions made regarding the main influences on snowshoe hare population and on Canadian lynx population.
(hint: snowshoe hare influences are talked about in the other snowshoe article, and Canadian lynx population is mainly linked to one factor)
What is the population cycles of snowshoe hares are influenced by multiple predators and food sources, while the lynx population depends primarily on the availability of hares?
400
In these conditions were surviving Chthamalus were smaller, resulting in lower reproductive efficiency
What are crowded conditions?
400
This species from the articles is considered a keystone species.
What is a snowshoe hare?
500
This was one take away from the snowshoe hare cycle article.
Possible answers
What is predator exclusion doubled hare population density?
What is supplemental food tripled hare population density?
What is combined predator exclusion and food addition increased hare populations 11-fold?
What is adding nutrients boosted plant growth but did not directly affect hare population?
What is food and predator control together had a stronger impact than either alone?
500
This is the name of one of the statistical models used to represent the relationship and interdependencies between snowshoe hares and Canadian lynx.
(half points for describing one of them without the name)
Two possible answers
What is the Vegetation-Hare Predator Model?
What is the Hare-Lynx Model?
500
This was one result from the experiment on the barnacle Chthamalus stellatus.
Accepted answers:
What is Chthamalus stellatus thrived in isolation from Balanus at all intertidal levels, indicating competition was the main issue in the lower zone.
What is high mortality rates for Chthamalus occurred when both species were present due to Balanus smothering and crushing them.
What is predation by Thais lapilius did not significantly affect Chthamalus survival?
What is surviving Chthamalus were smaller in crowded conditions, resulting in lower reproductive efficiency?

Name any potential future research relating to these articles. Could be one we mentioned or that you come up with.
Answers vary.
