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. -

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. -

Evaluation of differential white blood cell (leukocyte) counts from thin blood smears is one way to gain this information, and this approach is increasingly being used by herpetologists to gauge the integrity of amphibian populations. This approach is especially useful in natural settings because amphibian leucocyte profiles can vary depending on biological and physiological processes, including those caused by environmental factors. -

Ambystoma altamirani (Mountain Stream Siredon) is listed as Endangered by the International Union for Conservation of Nature (IUCN) Red List and as Threatened by the Mexican government. We report on the distribution, abundance, occupancy, population structure, and substrate use of A. altamirani, a stream dwelling salamander, along the Arroyo los Axolotes, Sierra de las Cruces, Mexico. We observed A. altamirani at least once during repeated surveys between February 2018 to December 2018 in 24 of 25 permanent 5-m long reaches separated by 40 m. The best model for occupancy had constant occupancy, detection, extinction, and colonization probabilities. Sites that dried at some time during the study had fewer observed individuals than those that did not dry. Size structure was relatively constant throughout the year, except for the appearance of small larvae in May, June, and July. -
The Salamanders of Tennessee
Salamanders of Tennessee: modified from Lisa Powers tnwildlife.org Follow links to Nongame The Salamanders of Tennessee Photo by John White Salamanders are the group of tailed, vertebrate animals that along with frogs and caecilians make up the class Amphibia. Salamanders are ectothermic (cold-blooded), have smooth glandular skin, lack claws and must have a moist environment in which to live. 1 Amphibian Declines Worldwide, over 200 amphibian species have experienced recent population declines. Scientists have reports of 32 species First discovered in 1967, the golden extinctions, toad, Bufo periglenes, was last seen mainly species of in 1987. frogs. Much attention has been given to the Anurans (frogs) in recent years, however salamander populations have been poorly monitored. Photo by Henk Wallays Fire Salamander - Salamandra salamandra terrestris 2 Why The Concern For Salamanders in Tennessee? Their key role and high densities in many forests The stability in their counts and populations Their vulnerability to air and water pollution Their sensitivity as a measure of change The threatened and endangered status of several species Their inherent beauty and appeal as a creature to study and conserve. *Possible Factors Influencing Declines Around the World Climate Change Habitat Modification Habitat Fragmentation Introduced Species UV-B Radiation Chemical Contaminants Disease Trade in Amphibians as Pets *Often declines are caused by a combination of factors and do not have a single cause. Major Causes for Declines in Tennessee Habitat Modification -The destruction of natural habitats is undoubtedly the biggest threat facing amphibians in Tennessee. Housing, shopping center, industrial and highway construction are all increasing throughout the state and consequently decreasing the amount of available habitat for amphibians. -
A Survey of Leukocyte Profiles of Red-Backed Salamanders from Mountain Lake, Virginia, and Associations with Host Parasite Types
Comparative Clinical Pathology (2019) 28:1743–1750 https://doi.org/10.1007/s00580-019-03015-9 ORIGINAL ARTICLE A survey of leukocyte profiles of red-backed salamanders from Mountain Lake, Virginia, and associations with host parasite types Andrew K. Davis1 & Claire Golladay2 Received: 7 March 2019 /Accepted: 9 July 2019 /Published online: 19 July2019 # Springer-Verlag London Ltd., part of Springer Nature 2019 Abstract In this project, red-backed salamanders, Plethodon cinereus, were collected from the heart of their range (Mountain Lake, Virginia, USA), in an effort to document the typical, or baseline, leukocyte profile of this species in its natural state. From microscopic examination of thin blood films, we determined relative proportions of all leukocyte types and determined the ratio of neutrophils to lymphocytes, which is a useful index of stress levels. In addition, individuals were examined for three naturally occurring endoparasites: two gastro-intestinal (trematodes and a ciliated protozoan in the genus Cepedietta) and one in the blood (a Rickettsial bacteria). This allowed us to conduct statistical comparisons of leukocyte data across parasite infection groups. Of 36 salamanders, 11 (31%) had trematode parasites, 7 (19%) contained Cepedietta parasites, 6 (17%) were parasitized by Rickettsia, and 12 had no parasites. The most common leukocytes were lymphocytes (87.4%), followed by neutrophils (4.2%), monocytes (3.3%), eosinophils (2.6%), and basophils (2.5%). The average neutrophil/lymphocyte ratio for these sala- manders was remarkably low (0.05) for an amphibian population. Statistical comparisons of leukocyte profiles among parasite infection groups indicated parasitized salamanders had twice as many circulating leukocytes as nonparasitized individuals, which could be considered an “inflammation response”. -
