Below is a graphical representation of a survey plot from each island, where icons represents different species and the abundance of each species is tallied in the table below. (note: these surveys may not represent the entire island patterns, so don't use these to try to answer the first question!)

A researcher is interested in the geographic ranges of two types of mountain ground squirrels that both use similar resources and occupy a similar amount of space on the mountain. Species A lives on the upper slopes, while species B lives a bit further down. The researcher is able to find a few areas where only one type of squirrel lives. In the location where only species A is found, populations live at approximately the same altitude as they do when both species are present. However, in locations where only species B is found, its population extends much higher on the mountain than they do when species A is also present. What can the researcher infer from this information? Species B has a larger realized niche than species A Species A has a larger fundamental niche than species B. Species A has a larger realized niche than species B. Species B has a larger fundamental niche than species A.
