The Figure on the Left Illustrates Species Boundaries as Assigned

question 2

Multiple Choice

The figure on the left illustrates species boundaries as assigned by the application of the biological species concept, while the figure on the right illustrates species boundaries as the result of the ecological species concept. What is the difference in how these boundaries are delineated when applying these concepts?

• A) The biological species concept uses the pattern of gene flow to assign boundaries, while the ecological species concept uses competition.
• B) The biological species concept uses shared, derived characters to assign boundaries, while the ecological species concept uses competition.
• C) The biological species concept uses competition to assign boundaries, while the ecological species concept uses gene flow.
• D) The biological species concept uses polymorphic characters to assign boundaries, while the ecological species concept uses shared, derived characters.

Definitions:

Poisson Model

A statistical model used to predict the count of events that happen independently and with a known constant mean rate.

Exponential Distribution

A probability distribution used to model time until an event occurs, assuming events happen independently at a constant average rate.

Probability

The measure of the likelihood that an event will occur, represented as a number between 0 and 1.

Exponentially Distributed

Pertains to a type of statistical distribution that describes the time between events in a process where events occur continuously and independently at a constant average rate.
