Imagine that you are trying to determine breeding dispersal patterns in four populations of kangaroo rats in Arizona.  You collect tissue samples for genetic information from the four populations of kangaroo rats designated (A, B, C, D).  Populations A and B are 2 miles apart.  Populations C and D are 1.5 miles apart.  However, populations A and B are approximately 20 miles apart from either population C or D.  Using microsatellite DNA techniques, you determine the following information from an assignment test.                                                              Population “Assigned” to   A B C D Population in which organism was trapped         A 15 0 10 2 B 12 20 1 1 C 10 4 25 0 D 2 3 19 23 Which of the following statements is NOT true?

(A) Nycteris is a carnivorous bat that ‘gleans’ prey such as frogs and lizards from the ground.  (B) Plecotus, the long-eared bat specializes on non-flying prey from leaves on trees.   (C) The Mexican free-tailed bat, Tararida forages insects high above the canopy. (D) Some species of Eptesicus, the big brown bat, forage for insects in small open clearings. For the four bat genera described above, describe a “typical” echolocation pattern for each bat in terms of where they forage and explain why they use the particular echolocation pattern for their foraging bouts.
