The Mystery Mousie Sciurus Gatsbyius – Jay’s Squirrel Sciurus Daisyius – Fay’s Squirrel

Cute mouse was found on St. Kitts island, did not know what it was but it was endangered bc of their habitats being threatened by commercialism starting in the 1920’s Jay Gatsby turned Kitts island into a popular vacation desintation during the 1920s adorned with art deco towers entangled into a tropical paradise. He brought in many new plants to kitts and began to change its environment. He brought in taller trees to shade guests. The Kitss rats needed to be faster overall to avoid encounter with humans and industrial projects. They mated faster, jumped further, ran further. Etc.  directional selectrion IN kitts, they were often hunted for their fur, had to mate ritual faster  behavioral isolation Since Kitts is filled with nightlife, the circadian rhythms of the Kitts rats changed and they now prefer to mate during the night since the island remains illuminated and the tourists are usually not everywhere.  temporal isolation The island of nevis and kitts were once connected by a small passage. But Gatsby wanted to create a snorkeling envlcave with room for a ferry ride so he created an artificial straight that isolated the two species  allopatric. The new island, Navis housed west indie locals and was kept alone. No new plant species were there.

How Gatsby lost Daisy: A Theory Dr. Fitzgerald for Nature August 5th 2017 3:00PM We have arrived at St. Kitts island, known as “Vegas of the Sea.” Despite the islands meager size, the island is filled with casinos and resorts. There appears to be little native Caribbean vegetation, instead grand tropical trees. The small rodents appear occasionally, picking scraps of the tourists food before scurrying away. Note: A local claims that these rodents used to be part of the fur trade on St. Kitts island. This trade is now illegal. August 6th 2017 We have traveled to a neighboring island, Nevis, which appears to teem with these rodents. The vegetation here is unlike St. Kitt’s highly decorative. Nevis is home to Cuban and Native Islanders, who are protected by law. There are some commercial facilities here, but not nearly as industrialized. We are planning to introduce the rat population from Nevis to St. Kitts in an attempt to restore the population September 10th 2017 The rodents will not mate, the appear to have no attraction to one another. We are lead to believe that the St. Kitts and Nevis rodents are not the same species. Morphological differences: September 12th 2017 A brief history of the islands, and our theories: The two islands, Nevis and St. Kitts had been connected by a land bridge before 1924. During the yeat 1924, an entrpenuer named Jay Gatsby transformed St. Kitts into a luxury destination for the roaring twenties. (Apparently he was trying to attract a woman?) He introduced many foreign plants, such as taller tropical trees to provide shade and exoticism for guests. This process gentrified the area, and locals were forced to relocate to the other side of the island, now Nevis. Gatsby then wanted to hide the locals and provide space for a ferry ride and snorkeling, in 1926 he arranged a straight to be made b/w that sepeated the islands. After all these renovations, the rodent populations began to evolve differently via these proposed mechanisms. Many of the locals that were stuck on St. Kitts could not interact with their tribes and were forced into the fur trade selling to foreign tourists, claiming that the fur was mink.
