Population Dynamics Quiz

What method of measuring populations involves defining a specific area and then counting all individuals in that area?

• Transect sampling

• Plot sampling

• Mark-recapture

• Aerial survey

Dandelions produce large amounts of seeds that are spread by the wind. What is the most likely population distribution of dandelions?

• Uniform distribution

• Clumped distribution

• Random distribution

• Even distribution

How does the scale affect the observed distribution of dandelions?

• At a larger scale, they appear uniformly distributed.

• At a larger scale, they appear randomly distributed.

• At a larger scale, they appear clumped.

• At a larger scale, they appear evenly distributed.
