BACKGROUND As an expert in the field of mammalian reproductive strategies, you have been hired by the Caribbean Department of Nature and Island Resources. This organization is a cooperative of several Caribbean islands concerned with the loss of biological diversity on their island nations as tourism and development continue to grow. Scientists working on the island of St. Kitts and its sister island Nevis have uncovered what appears to be a previously undiscovered species of rodent. Based on the original description of this animal, it was placed in a genus within the squirrel family. What you have been hired to do is to help save the population on St. Kitts, which is small and threatened by development. The population is so small that individuals are having difficulty finding mates, with many members of the population failing to mate at all during the annual mating season. When you arrive in the region and begin your observations, you notice that the Nevis population is very healthy and could be used as stock for the recovery operation that you plan on the island of St. Kitts. In your recovery plan, you bring animals from Nevis into the population on St. Kitts to bolster the population numbers, ensure the availability of mates, and increase genetic diversity within the shrinking population. As a good scientist, you observe the reproductive behaviors of these animals in the field to ensure the success of your program. Within a very short time, you realize that your plan is failing. After the introduction of 240 Nevis rodents into the St. Kitts population, you are unable to observe a single successful reproductive event. Although these animals look very similar, you are concerned that they are two distinct species. Your focus now becomes identifying the differences between the two populations. What follows is a brief review of the data you collected from your study. ST. KITTS RODENT NEVIS RODENT Average weight: 83 g Average weight: 86 g Average length: 21.8 cm Average length: 23.3 cm Average hind limb: 4.2 cm Average hind limb: 8.8 cm Average forelimb: 3.9 cm Average forelimb: 6.1 cm Primary food source: Ground berries Primary food source: Tree nuts Average number of offspring per litter: 2 Average number of offspring per litter: 6 Average time spent in courtship display: 12.6 seconds Average time spent in courtship display: 41.3 seconds Mating season: July-August Mating season: July - August (a) (4 points) Based on the data above, describe 2 possible pre-zygotic barriers that might be preventing interbreeding between the St. Kitts rodents and those introduced from Nevis. (b) (4 points) Describe an experiment you might want to conduct to determine whether or not speciation has occurred. Don’t forget controls! (c) (4 points) Outline a scientifically plausible sequence of events that could have produced the two rodent populations via allopatric speciation. Be sure to include a description of the evolutionary forces that created these two distinct populations.
