The Pearl Map Turtle, (Graptemys pearlensis<\/em>) is found in the Pearl River in Louisiana and Mississippi. Graptemys means \u201cmap turtle\u201d in Greek, and are so named for the map-like pattern of light colored lines often seen on their shells. Pearlensis means \u201cfrom the pearl\u201d in Latin, referencing the river this turtle calls home.<\/figcaption><\/figure>\n

After 30 years of research and authoring two\u00a0books<\/a>\u00a0on turtles and tortoises,\u00a0Jeff Lovich<\/strong>\u00a0still talks about the subjects of his research with infectious enthusiasm.<\/p>\n

In his office in the ARD building on the NAU campus, he animatedly describes the differences between turtles and tortoises.<\/p>\n

\u201cTurtles, tortoises and terrapins are all turtles because they have a shell and a backbone,\u201d Lovich says. \u201cTortoises and turtles can be distinguished from each other by the shape of their hind limbs. A turtle has distinct toes on the hind feet whereas a tortoise,\u201d he says, as he curls under his fingers, \u201chas short toes like an elephant.\u201d<\/p>\n

Upon speaking with Josh Ennen<\/strong>, one begins to wonder if enthusiasm for turtles is, in fact, contagious.<\/p>\n

As the lead author in the classification of the Pearl River Map Turtle, Ennen not only named the new species but also made a name for himself.<\/p>\n

Having access to research facilities, faculty and students at NAU has created a community partnership that Lovich and Ennen value. And with access to geologic, geographic, hydrological and biological data at the USGS, putting a new turtle on the map has gotten even simpler.<\/span>A wildlife biologist position at NAU with the USGS\u2019s Colorado Plateau Research Station brought Ennen to Flagstaff in March, giving him the opportunity to work with coauthor Lovich.<\/p>\n

\u201cThe collaborative relationship between NAU and the USGS has lead to very good research,\u201d Lovich said. \u201cNAU is a great place to be an ecologist.\u201d<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

When scientists announce the discovery of a new animal species, we often imagine exotic, difficult to reach locations\u2014the untouched shore of a distant island, the forests of the rain-drenched Amazon or the darkest depths of the Arctic Ocean.<\/p>\n

But the recent announcement of a new species of turtle in the southeastern United States proves that even in a country considered to be well-explored, perhaps more awaits discovery.<\/p>\n

In June,\u00a0Jeff Lovich<\/strong>, NAU adjunct faculty member in biology, and\u00a0Josh Ennen<\/strong>, NAU affiliate, published the discovery of a new species of turtle in\u00a0Chelonian Conservation and Biology International Journal of Turtle and Tortoise Research<\/em>.<\/p>\n

Found in the Pearl River, which flows through Mississippi and Louisiana before it meets the Gulf of Mexico, the newly named Pearl Map Turtle, or\u00a0Graptemys pearlensis<\/em>, had been mistaken for a turtle native to the neighboring Pascagoula River. Ennen found it odd that the Pascagoula Map Turtle was found in both rivers and wanted to further investigate.<\/p>\n

Ennen was completing his dissertation at University of Southern Mississippi when he decided to take a closer look at the inhabitants of the two rivers. His research led him to Lovich, who had found, described and named the last turtle species in the same region in 1992.<\/p>\n

\u201cI was familiar with Jeff\u2019s work when questions started coming up,\u201d Ennen said. \u201cBased on the genetics, morphology and geographic isolation, I was considering classifying the turtles as distinct population segments when I decided to contact Jeff.\u201d<\/p>\n

Lovich, a research ecologist with U.S. Geological Survey\u2019s Colorado Plateau Station at NAU, shared his findings and insight as the scientists built their case for classification of the new turtle species. His access to geologic and geographic data with the USGS assisted in their developing theory that the turtles had evolved into a separate species.<\/p>\n

\u201cYou\u2019d expect to see similar aquatic species in these rivers due to their proximity,\u201d Lovich said. \u201cHowever, with sea level changes associated with glacial and interglacial periods in the past, animals in these rivers were periodically separated for tens of thousands to millions of years.\u201d<\/p>\n

Ennen and Lovich observed pattern variations between turtles in two rivers, and examining their DNA verified that the turtle endemic to each river was a different species.<\/p>\n

The announcement of the Pearl Map Turtle, \u201cGenetic and morphological variation between populations of the Pascagoula Map Turtle (Graptemys gibbonsi<\/em>) in the Pearl and Pascagoula Rivers with description of a new species,\u201d brings the number of native turtle species in the United States to 57, including six in Arizona, with approximately 320 species documented worldwide.<\/p>\n","protected":false},"excerpt":{"rendered":"
