The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N.

Pseudoeurycea Naucampatepetl. the Cofre De Perote Salamander Is Endemic to the Sierra Madre Oriental of Eastern Mexico. This
Pseudoeurycea naucampatepetl. The Cofre de Perote salamander is endemic to the Sierra Madre Oriental of eastern Mexico. This relatively large salamander (reported to attain a total length of 150 mm) is recorded only from, “a narrow ridge extending east from Cofre de Perote and terminating [on] a small peak (Cerro Volcancillo) at the type locality,” in central Veracruz, at elevations from 2,500 to 3,000 m (Amphibian Species of the World website). Pseudoeurycea naucampatepetl has been assigned to the P. bellii complex of the P. bellii group (Raffaëlli 2007) and is considered most closely related to P. gigantea, a species endemic to the La specimens and has not been seen for 20 years, despite thorough surveys in 2003 and 2004 (EDGE; www.edgeofexistence.org), and thus it might be extinct. The habitat at the type locality (pine-oak forest with abundant bunch grass) lies within Lower Montane Wet Forest (Wilson and Johnson 2010; IUCN Red List website [accessed 21 April 2013]). The known specimens were “found beneath the surface of roadside banks” (www.edgeofexistence.org) along the road to Las Lajas Microwave Station, 15 kilometers (by road) south of Highway 140 from Las Vigas, Veracruz (Amphibian Species of the World website). This species is terrestrial and presumed to reproduce by direct development. Pseudoeurycea naucampatepetl is placed as number 89 in the top 100 Evolutionarily Distinct and Globally Endangered amphib- ians (EDGE; www.edgeofexistence.org). We calculated this animal’s EVS as 17, which is in the middle of the high vulnerability category (see text for explanation), and its IUCN status has been assessed as Critically Endangered. -

Ctenosaura Defensor (Cope, 1866)
Ctenosaura defensor (Cope, 1866). The Yucatecan Spiny-tailed Iguana, a regional endemic in the Mexican Yucatan Peninsula, is distributed in the Tabascan Plains and Marshes, Karstic Hills and Plains of Campeche, and Yucatecan Karstic Plains regions in the states of Campeche, Quintana Roo, and Yucatán (Lee, 1996; Calderón-Mandujano and Mora-Tembre, 2004), at elevations from near “sea level to 100 m” (Köhler, 2008). In the original description by Cope (1866), the type locality was given as “Yucatán,” but Smith and Taylor (1950: 352) restricted it to “Chichén Itzá, Yucatán, Mexico.” This lizard has been reported to live on trees with hollow limbs, into which they retreat when approached (Lee, 1996), and individuals also can be found in holes in limestone rocks (Köhler, 2002). Lee (1996: 204) indicated that this species lives “mainly in the xeric thorn forests of the northwestern portion of the Yucatán Peninsula, although they are also found in the tropical evergreen forests of northern Campeche.” This colorful individual was found in low thorn forest 5 km N of Sinanché, in the municipality of Sinanché, in northern coastal Yucatán. Wilson et al. (2013a) determined its EVS as 15, placing it in the lower portion of the high vulnerability category. Its conservation status has been assessed as Vulnerable by the IUCN, and as endangered (P) by SEMARNAT. ' © Javier A.

Joshua McCausland Molecular systematics of Characodon: Phylogeny based on a nuclear locus A Thesis Presented to the Honors Faculty of the University of North Georgia by Joshua McCausland Dahlonega, GA January 2014 Characodon Systematics Accepted by the Honors Faculty of the University of North Georgia in partial fulfillment of the requirements for the title of Honors Program Graduate Thesis Committee: Characodon Systematics Abstract Characodon is a genus of livebearing fishes whose two extant species (C. lateralis and C. audax) inhabit localities along the Río Mezquital of Durango, Mexico. This lineage of Goodeidae (Cyprinodontiformes) is critical to study because of its biogeographic and phylogenetic positions within the group, and both species are of conservation concern. A recent mitochondrial DNA analysis contradicts the published taxonomy, and suggests that Characodon has diverged into northern and southern populations. This, coupled with the observation that the morphological characteristics used in the original species descriptions might be flawed, has led me to study the phylogenetic relationships among populations using a third kind of evidence, nuclear DNA. -
