We conducted a phylogenetic analysis of DNA sequences from 3 adjacent genes (12S rRNA, tRNAVal, and 16S rRNA) in the mitochondrial genome from representatives of 14 phyllostomid genera including 7 species of Tonatia. Previous studies of the systematic relationships within Tonatia document that some members of this group are extremely divergent from others.(More)
In 2010 a mammal survey was conducted in an ecotone region (including páramo and temperate forest) on the eastern slope of the Andes in Sangay National Park, Ecuador. Sherman traps, Tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (3,400 m elevation and 2,962 m elevation). A total of 169 specimens representing(More)

OBJECTIVE This study involves investigation of the use of video-imaging for measurement of volumetric shrinkage of composites. METHODS Six composites were tested for volumetric shrinkage using video-imaging. The volumetric shrinkage was measured using the single- and multi-view volumetric reconstruction modes. All composites were cured using a VIP(TM)(More)
A mammal survey was conducted at 2500 m on the eastern slope of Volcán Sumaco, Napo Province, Ecuador. Volcán Sumaco is located east of the eastern slope of the Andes. The mountain is isolated from the eastern cordillera of the Andes by the Río Cosanga and Río Quijos River Valleys. The ecosystem of the survey area is Temperate Mountain Forest (Sierra 1999).(More)
In 2008 a mammal survey was conducted in humid tropical forest on the western slope of the Andes near the town of Santa Rosa. Sherman traps, tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (450 m elevation and 702 m elevation). A total of 113 specimens of 32 species were collected from the survey area.(More)
Using small-angle x-ray diffraction from centrifugally oriented acetylcholine receptor (AChR) enriched membranes coupled with anomalous scattering from terbium ions (Tb3+) titrated into presumed Ca2+ binding sites, we have mapped the distribution of Tb3+ perpendicular to the membrane plane using a heavy atom refinement algorithm. We have compared the(More)
The rapid diversification of Myotis bats into more than 100 species is one of the most extensive mammalian radiations available for study. Efforts to understand relationships within Myotis have primarily utilized mitochondrial markers and trees inferred from nuclear markers lacked resolution. Our current understanding of relationships within Myotis is(More)
The cytochrome-b gene was sequenced and data were analyzed for 104 Perognathus from localities in Mexico, Arizona, California, New Mexico, Oklahoma, and Texas to evaluate the validity of P. flavus and P. merriami and to assess the occurrence of species of Perognathus in Oklahoma. Unweightedparsimony, minimum-evolution, maximum-likelihood (TrN+I+G), and(More)
In 2014, a mammal survey was conducted in an ecotone region (including páramo and temperate forest) on the Eastern Versant of the Andes in Carchi province, Ecuador. Sherman traps, Tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (3,340 m elevation and 3,650 m elevation). A total of 142 specimens representing 14(More)
