Lemurs on St. Kitts and Nevis
By: Austin Jordan and Robert Zullo
We noticed that the population of a rodent on St. Kitts was going down. We noticed that there was a similar rodent on the bordering island of Nevis. In order to try and save the rodent on St. Kitts were attempting to bring some of the rodents that were similar over to see if we could see successful reproduction. We brought over the rodents from Nevis, and we noticed that not much was going on. After 240 attempts we realized that no reproductive activity occurred. We noticed in the attempts that the two rodents did not really attempt to mate. We did see very few attempt to mate but saw no reproductive results. After noticing this we have now made the assumption that the rodents are now of different species. We believe that the rodents experienced allopatric speciation. We believe that the two rodents were once of the same species but because of the separation they experienced changes in order to better fit there environment. The rodent from St. Kitts has a longer hind leg and higher leap than the rodent from Nevis. This could have been caused by a need to jump on tree limbs. This is caused by natural selection because the St. Kitts rodent needs a longer hind leg to live in an environment that is tree infested. The two rodents have developed into new species meaning that these rodents are not able to mate. We will now just have to protect the rodent St. Kitts because we can’t really get them to reproduce.
