In the following figure, the isthmus separates the Pacific Ocean on the left (side A) from the Caribbean (Atlantic Ocean) on the right (side B). The seawater on either side of the isthmus is separated into five depth habitats (15), with 1 being the shallowest.Why should deepwater shrimp on different sides of the isthmus have diverged from each other earlier than shallow-water shrimp?

Figure 23.5Which period had the greatest rate of extinction?

In Biogeography, the term secular migration refers to…

Why is the slope of the species area curve (from the equation S = cAz) different when looking at increasing island size vs. increasing sample area on a mainland? What causes the difference?

It is estimated that there are about ____________ species on the planet.

Use the accompanying figure to answer this question: What two variables were manipulated?

We take for granted that the temperature in Wisconsin is generally lower than the temperature at the equator. Briefly, give one reason for this temperature pattern.

Based on the speciesarea plot in the accompanying figure, if habitable area on an island were reduced from 10,000 km2 (square kilometers) to 1 km2, roughly what percentage of the species would disappear?

According to the Equilibrium Theory of Island Biogeography, what determines species richness on an island?

Species often arrive at an area by catching a ride on other species—including hosts. For example, a strain of cholera common in Nepal was introduced to Haiti in 2010 by infected UN workers who traveled from Nepal to Haiti. With respect to the cholera pathogen, what type of dispersal is this an example of?
