Aquiloeurycea Scandens (Walker, 1955). the Tamaulipan False Brook Salamander Is Endemic to Mexico
Aquiloeurycea scandens (Walker, 1955). The Tamaulipan False Brook Salamander is endemic to Mexico. Originally described from caves in the Reserva de la Biósfera El Cielo in southwestern Tamaulipas, this species later was reported from a locality in San Luis Potosí (Johnson et al., 1978) and another in Coahuila (Lemos-Espinal and Smith, 2007). Frost (2015) noted, however, that specimens from areas remote from the type locality might be unnamed species. This individual was found in an ecotone of cloud forest and pine-oak forest near Ejido La Gloria, in the municipality of Gómez Farías. Wilson et al. (2013b) determined its EVS as 17, placing it in the middle portion of the high vulnerability category. Its conservation status has been assessed as Vulnerable by IUCN, and as a species of special protection by SEMARNAT.

Additionally, valuable peer reviews of a draft of this document were provided by Lora Smith (Jones Ecological Research Center) , Dirk Stevenson (Altamaha Consulting), Dr. Eric Hoffman (University of Central Florida), Dr. Susan Walls (USGS), and other partners, including members of the Striped Newt Working Group. We appreciate their comments, which resulted in a more robust status assessment and final report. EXECUTIVE SUMMARY This Species Status Assessment (SSA) is an in-depth review of the striped newt's (Notophthalmus perstriatus) biology and threats, an evaluation of its biological status, and an assessment of the resources and conditions needed to maintain species viability. We begin the SSA with an understanding of the species’ unique life history, and from that we evaluate the biological requirements of individuals, populations, and species using the principles of population resiliency, species redundancy, and species representation. All three concepts (or analogous ones) apply at both the population and species levels, and are explained that way below for simplicity and clarity as we introduce them. The striped newt is a small salamander that uses ephemeral wetlands and the upland habitat (scrub, mesic flatwoods, and sandhills) that surrounds those wetlands. -
Scientific Publication of Georeferenced Molecular Data As an Adequate Guide to Delimit the Range of Korean Hynobius Salamanders Through Citizen Science

Despite the importance of clearly assessing the distribution boundaries of species, it is not possible for sci- entists to acquire genetic information and conduct molecular analysis for all populations. Consequently, citizen sci- ence is of increasing importance for large scale data collection. In this study, we described the range boundaries of the four Hynobius species occurring in Korea based on genetic identification and refined their distribution through citizen science data. The genetic identification of individuals was extracted from the literature, while the citizen science data were extracted from iNaturalist through GBIF. Distribution boundary lines were drawn from the genetic data and consistency with citizen science datapoints was assessed through a comparative analysis with the points found beyond the established boundary lines. -

Published online at www.senckenberg.de / vertebrate-zoology on 4.v.2015. Abstract The development of the bony skeleton in a partially embryonized lotic-breeding salamander Hynobius formosanus is studied using the ontogenetic series from late embryos to postmetamorphic juveniles and adult specimen. Early stages of skull development in this spe- cies are compared with the early cranial ontogeny in two non-embryonized lentic-breeding species H. lichenatus and H. nigrescens. The obtained results show that skeletal development distinguishes H. formosanus from other hynobiids by a set of important features: 1) the reduction of provisory ossifications (complete absence of palatine and reduced state of coronoid), 2) alteration of a typical sequence of ossification appearance, namely, the delayed formation of vomer and coronoid, and 3) the absence of a separate ossification center of a lacrimal and formation of a single prefrontolacrimal. These unique osteological characters in H. formosanus are admittedly connected with specific traits of its life history, including partial embryonization, endogenous feeding until the end of metamorphosis and relatively short larval period. -
Comparative Osteology and Evolution of the Lungless Salamanders, Family Plethodontidae David B
COMPARATIVE OSTEOLOGY AND EVOLUTION OF THE LUNGLESS SALAMANDERS, FAMILY PLETHODONTIDAE DAVID B. WAKE1 ABSTRACT: Lungless salamanders of the family Plethodontidae comprise the largest and most diverse group of tailed amphibians. An evolutionary morphological approach has been employed to elucidate evolutionary rela tionships, patterns and trends within the family. Comparative osteology has been emphasized and skeletons of all twenty-three genera and three-fourths of the one hundred eighty-three species have been studied. A detailed osteological analysis includes consideration of the evolution of each element as well as the functional unit of which it is a part. Functional and developmental aspects are stressed. A new classification is suggested, based on osteological and other char acters. The subfamily Desmognathinae includes the genera Desmognathus, Leurognathus, and Phaeognathus. Members of the subfamily Plethodontinae are placed in three tribes. The tribe Hemidactyliini includes the genera Gyri nophilus, Pseudotriton, Stereochilus, Eurycea, Typhlomolge, and Hemidac tylium. The genera Plethodon, Aneides, and Ensatina comprise the tribe Pleth odontini. The highly diversified tribe Bolitoglossini includes three super genera. The supergenera Hydromantes and Batrachoseps include the nominal genera only. The supergenus Bolitoglossa includes Bolitoglossa, Oedipina, Pseudoeurycea, Chiropterotriton, Parvimolge, Lineatriton, and Thorius. Manculus is considered to be congeneric with Eurycea, and Magnadig ita is congeneric with Bolitoglossa. Two species are assigned to Typhlomolge, which is recognized as a genus distinct from Eurycea. No. new information is available concerning Haptoglossa. Recognition of a family Desmognathidae is rejected. All genera are defined and suprageneric groupings are defined and char acterized. Range maps are presented for all genera. Relationships of all genera are discussed. -

Given the lack of reports since 1976, the minute plethodontid salamander Thorius narismagnus is widely considered as missing. However, this report describes the rediscovery of this minute salamander at the type locality (Volcán San Martín), as well as a new locality on Volcán Santa Marta, 28 km southeast of its previously known distribution, both in the Los Tuxtlas region of Veracruz, Mexico. The localities where T. narismagnus has been found are mature forests in a community reserve on Volcán San Martín and a private reserve on Volcán Santa Marta. The presence of maxillary teeth, generally absent in Thorius, are reported here in some T. narismagnus females. Two efforts which may contribute to the conservation of Thorius narismagnus are the preservation of the cloud forests where this species persists, as well as the determination of the presence and possible effect of chytrid fungus in these populations. -

Vernacular Name AMPHIUMA, ONE-TOED (Aka: Congo Eel, Congo Snake, Ditch Eel, Fish Eel and Lamprey Eel)
1/6 Vernacular Name AMPHIUMA, ONE-TOED (aka: Congo Eel, Congo Snake, Ditch Eel, Fish Eel and Lamprey Eel) GEOGRAPHIC RANGE Eastern Gulf coast. HABITAT Wetlands: slow moving or stagnant freshwater rivers/streams/creeks and bogs, marshes, swamps, fens and peat lands. CONSERVATION STATUS IUCN: Near Threatened (2016). Population Trend: Decreasing. Because of the limited extent of its occurrence and because of the declining extent and quality of its habitat, this species is close to qualifying for Vulnerable. COOL FACTS Amphiumas are commonly known as "Congo eels," a misnomer. First of all, amphiumas are amphibians, rather than fish (which eels are). This notwithstanding, amphiumas bear resemblance to the elongate fishes. It is easy to overlook the diminutive legs, and the lack of any external gills adds to the similarity between the amphiumas and eels. Amphiumas are adapted for digging and tunneling. They seem to spend most of the time in muddy burrows and are rarely observed in the wild. They never fully metamorphose and retain larval characteristics in varying degrees into adulthood: one pair of the larval gill slits is retained and never disappears, no eyelids, no tongue and the presence of 4 gill arches with a single respiratory opening between the 3 rd--4th arches. Amphiumas have two pairs of limbs, and the three species, all of which occur in the S.E. U.S, differ in regard to the number of toes at the ends of these limbs: one, two or three. These amphiumas possess tiny, single-toed limbs, one pair just behind the small gill opening at each side of the neck and another pair just ahead of the longitudinal anal slit . -
Successful Reproduction of the Mole Salamander Ambystoma Talpoideum in Captivity, with an Emphasis on Stimuli Environmental Determinants
SHORT NOTE The Herpetological Bulletin 141, 2017: 28-31 Successful reproduction of the mole salamander Ambystoma talpoideum in captivity, with an emphasis on stimuli environmental determinants AXEL HERNANDEZ Department of Environmental Sciences, Faculty of Sciences and Technics, University Pasquale Paoli of Corsica, Corte, 20250, France Author Email: [email protected] ABSTRACT - Generating and promoting evidence-based husbandry protocols for urodeles, commonly known as newts and salamanders, is urgently needed because most of the up-to-date ex situ programs are focused on frogs and toads than Urodela. Data on biology, life history, ecology and environmental parameters are lacking for many species and are needed to establish suitable husbandry and breeding conditions in captive environments. Two adult females and two adult males, of the mole salamander Ambystoma talpoideum successfully reproduced in captivity. It was found that reproduction of this species depends on various complex stimuli: including natural photoperiod 12:12, rainwater (acidic to neutral pH) and an aquarium full of various debris. Additionally high temperature variations ranging from 2 °C to 17 °C (a decrease followed by an increase) between November and February showed that it is possible to breed adults in aquariums provided the right stimuli are applied at the right moment of time in winter. A. talpoideum shows an explosive breeding mode as previously reported for the whole genus Ambystoma. INTRODUCTION with an emphasis on the environmental determinant stimuli involved.
