Morelia, Michoacán, México 3Instituto de Investigaciones sobre los Recursos Naturales, Universidad Michoacana de San Nicolás de Hidalgo. Morelia, Michoacán, México Global climate change represents one of the most important threats to wildlife populations. Amphibians, specifically salamanders, are particularly susceptible to the effects of a changing climate due to their restrictive physiological requirements and low vagility; however, little is known about which amphibian species are more vulnerable to climate change. Therefore, we aimed to forecast changes in the distribution of the mountain stream salamander, Ambystoma ordinarium, using different climate scenarios. Approximately 70 representative presence records were selected to model the current potential distribution and two scenarios based on 2070 climate projections (RCP 2.6 and RCP 8.5) using the MaxEnt algorithm and three global climate models (BCC-CSM1-1, CCSM4 and HadGEM2-ES). A total of three scenarios were simulated using the 10-percentile training presence as the threshold rule. For all scenarios, the average of the area under the receiver operating characteristic curve for the replicated runs was greater than 0.95 ± 0.005, representing good performance for the current and projected geographical distributions of A. -

The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom
lopmen ve ta e l B Williamson, Cell Dev Biol 2012, 1:1 D io & l l o l g DOI: 10.4172/2168-9296.1000101 e y C Cell & Developmental Biology ISSN: 2168-9296 Research Article Open Access The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom Abstract The larval transfer hypothesis states that larvae originated as adults in other taxa and their genomes were transferred by hybridization. It contests the view that larvae and corresponding adults evolved from common ancestors. The present paper reviews the life histories of chordates, and it interprets them in terms of the larval transfer hypothesis. It is the first paper to apply the hypothesis to craniates. I claim that the larvae of tunicates were acquired from adult larvaceans, the larvae of lampreys from adult cephalochordates, the larvae of lungfishes from adult craniate tadpoles, and the larvae of ray-finned fishes from other ray-finned fishes in different families. The occurrence of larvae in some fishes and their absence in others is correlated with reproductive behavior. Adult amphibians evolved from adult fishes, but larval amphibians did not evolve from either adult or larval fishes. I submit that [1] early amphibians had no larvae and that several families of urodeles and one subfamily of anurans have retained direct development, [2] the tadpole larvae of anurans and urodeles were acquired separately from different Mesozoic adult tadpoles, and [3] the post-tadpole larvae of salamanders were acquired from adults of other urodeles. Reptiles, birds and mammals probably evolved from amphibians that never acquired larvae. -

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. -
Dusky Salamander Desmognathus Fuscus
WILDLIFE IN CONNECTICUT WILDLIFE FACT SHEET PAUL J. FUSCO PAUL Dusky Salamander Desmognathus fuscus Background and Range The northern dusky salamander is in the lungless salamander family (Plethodontidae). This species was historically distributed widely in streams, springs, and seepage areas throughout Connecticut. However, it has become scarce in more developed areas of the state, especially in Fairfield, New Haven, and Hartford Counties. The northern dusky salamander ranges from south Quebec and southern New Brunswick, down the Appalachians to its southernmost point in mid-South Carolina. Its western extent reaches east Indiana and the eastern half of Kentucky. In Connecticut, it is found statewide but only sparsely in New London and Fairfield counties. Description This stout, medium-sized salamander exhibits variable brown coloration with mottling, and a translucent belly that has “salt and pepper” patterning. The tail is flattened laterally, with a knife-like top edge. A small white line runs from the jaw to the eye, and a groove goes from each nostril to the jaw edge. Hind legs are noticeably larger than forelimbs. Younger individuals have a greater range in color from olive to chestnut to dark tan. Larvae possess a few pairs of yellowish spots bordered with a dark, wavy lateral line that goes along the back. Larvae can be confused with the larger two-lined salamander; however, the two-lined has less pronounced rear limbs. Habitat and Diet The northern dusky is usually found in or near freshwater, such as streams, springs, and/or areas with seepage.

However, few reports have appeared in herein may be novel for D. fuscus and potentially the literature regarding tail bifurcations in natural for the genus Desmognathus.

Nonforested habitats such as open fields and pastures have been considered unsuitable for desiccation-prone woodland salamanders such as the Eastern Red-backed Salamander (Plethodon cinereus). Recent research has suggested that Plethodon cinereus may not only disperse across but also reside within open habitats including fields, meadows, and pastures. However, presence and high densities of P. cinereus within agriculturally disturbed habitats may be misleading if these populations exhibit atypical demographic characteristics or decreased physical condition relative to forest populations. We surveyed artificial cover boards from 2004-2005 to compare physical condition, sex ratios, and age-class structure of P. -
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. These data may assist in improving breeding these ince the 1980s, the current global amphibian extinction salamanders under artificial conditions. crisis has been discussed and acknowledged (Wake, A. -
