Comparative Morphometrics of the Sacral Vertebra in <em>Aneides</em> (Caudata: Plethodontidae).
<p>The genus <em>Aneides</em> (Caudata: Plethodontidae) is an arboreal salamander with a prehensile tail and a distribution that spans North America. It is hypothesized that adaptations for arboreality will be visible in the osteology of the sacral vertebra either by qualitative analysis or linear …

Postglacial ostracod distribution and paleoecology, Devils Lake basin, northeastern North Dakota
… consists of Candona acutula, C. candida, C. caudata, C. decora, C, ohioensis, C. lactea, C. pronopa, C. rawsoni, Cypridopsis vidua, Cyclocypris ampla, and Limnocythere (Limnocytherina) itasca. Only two species are in common in the two faunas. Variations of diversity, similarity, and …

Novel approaches for large-scale phylogenetics and applications in the context of the amphibian tree of life
… three lineages of the extant amphibians (Anura, Caudata and Gymnophiona) using an independent source of evidence: miRNAs, recently used to help resolve difficult phylogenetic problems. The analyses yielded a high number of shared miRNAs using the Xenopus tropicalis genome, contrasting with a …

Rise of present-day tetrapods in the paleotropics of Late Triassic equatorial Pangaea: new insights from microvertebrate data
… to Recent] Fauna', =LTF; i.e. Salientia, Caudata, Gymnophiona, Mammaliaformes, Squamata, Rhynchocephalia, Testudinata, Crocodylomorpha, and Dinosauria). With few exceptions, only the LTF assemblage survives the end-Triassic Extinction (~201.5 Ma), highlighting the Late Triassic (~227–201.5 …

Survivorship of ploidy-variable unisexual <i>ambystoma</i> aalamanders across developmental stages
<p>Unisexual <em>Ambystoma</em> produce ploidy-variable offspring that differ in survivorship to adulthood. These populations reproduce through kleptogenesis, persisting by stealing genetic material from males of compatible bisexual <em>Ambystoma</em> species (e.g., Jefferson's Salamander <em>A. …

Proximate Causes of Alternative Reproductive Tactics in Blue Ridge Two-Lined Salamanders (Eurycea cf. wilderae)
<p>Alternative reproductive tactics (ARTs) refer to discrete variation in reproductive behavior between members of a sex and within a species. ARTs are present in Blue Ridge two-lined salamanders (<em>Eurcyea</em> cf. <em>wilderae</em>) in the form of male polymorphism. Two male morphs exist: …

Genetic, Morphological, and Behavioral Analysis of the Oklahoma Salamander (Eurycea Tynerensis) in Southwestern Missouri
I investigated populations of Eurycea tynerensis which differed in coloration and life history mode. Using morphometrics and behavioral trials, I tested two sympatric color morphs for the presence of a cryptic species. I also obtained sequence data from the mitochondrial cytochrome-b gene of 21 …

Salamanders of the Mio-Pliocene Gray Fossil Site, Washington County, Tennessee.
<p>Screening efforts at the Gray Fossil Site, Washington County, Tennessee, have yielded a unique and diverse salamander fauna for the southern Appalachian Mio-Pliocene; including at least five taxa from three modern families (Ambystomatidae, Plethodontidae, and Salamandridae) supporting the …
