Amphibian Identification Guide
Amphibian Migrations & Road Crossings Amphibian Identification Guide The NYSDEC Hudson River Estuary Program and Cornell University are working with communities to conserve forests, woodland pools, and the wildlife that depend on these critical habitats. This guide is designed to help volunteers of the Amphibian Migrations & Road Crossings Project identify species they observe during spring migrations, when many salamanders and frogs move from forest habitat to woodland pools for breeding. For more information about the project, visit http://www.dec.ny.gov/lands/51925.html. spotted salamander* (Ambystoma maculatum) Black to dark gray body with two rows of yellow spots. Widespread distribution in the Hudson Valley. Total length 5.0-8.0 in. Jefferson/blue-spotted salamander complex* (Ambystoma jeffersonianum x laterale) Brown to grayish black with blue-silver flecking. Less common. Note: Hybridization between Jefferson and blue-spotted salamander has created very variable appearances and individuals may have features of both species. Because even experts have difficulty distinguishing these two species in the field, we consider any sightings to be the ‘complex.’ Total length 3.0-7.5 in. marbled salamander* (Ambystoma opacum) Black or grayish-black body with white or gray crossbars along length of body.

Red-Spotted Newt Fact Sheet
WILDLIFE IN CONNECTICUT WILDLIFE FACT SHEET DENNIS QUINN Eastern Red-spotted Newt Notophthalmus v. viridescens Background and Range The red-spotted newt (also commonly referred to as the eastern newt) is widespread and familiar in many areas of Connecticut. Newts have four distinct life stages: egg, aquatic larvae, terrestrial juvenial (or “eft”), and aquatic adult. Their life cycle is one of the most complex of all the salamanders; starting as an egg, hatching into a larvae with external gills, then migrating to terrestrial habitats as juveniles where gills are replaced with lungs, and returning a few years later to their aquatic habitats as adults which retain their lungs. In Connecticut, the newt is found statewide, but more prominently west of the Connecticut River. The red-spotted newt has many subspecies and an extensive range throughout the United States. Description The adult red-spotted newt has smooth skin that is overall greenish in color, with small black dots scattered on the back and a row of several black-bordered reddish-orange spots on each side of the back. Male newts have black rough patches on the inside of their thighs and on the bottom tip of their hind toes during the breeding season. Adult newts are usually 3 to 5 inches in length. The juvenile, or eft, stage of the red-spotted newt is bright orange in color with small black dots scattered on the back and a row of larger, black-bordered orange spots on each side of the back. The skin is rough and dry compared to the moist and smooth skin of adults and larvae. -
Chemical Defense of the Eastern Newt (Notophthalmus Viridescens): Variation in Efficiency Against Different Consumers and in Different Habitats
Chemical Defense of the Eastern Newt (Notophthalmus viridescens): Variation in Efficiency against Different Consumers and in Different Habitats Zachary H. Marion1,2, Mark E. Hay1* 1 School of Biology, Georgia Institute of Technology, Atlanta, Georgia, United States of America, 2 Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville, Tennessee, United States of America Abstract Amphibian secondary metabolites are well known chemically, but their ecological functions are poorly understood—even for well-studied species. For example, the eastern newt (Notophthalmus viridescens) is a well known secretor of tetrodotoxin (TTX), with this compound hypothesized to facilitate this salamander’s coexistence with a variety of aquatic consumers across the eastern United States. However, this assumption of chemical defense is primarily based on observational data with low replication against only a few predator types. Therefore, we tested the hypothesis that N. viridescens is chemically defended against co-occurring fishes, invertebrates, and amphibian generalist predators and that this defense confers high survivorship when newts are transplanted into both fish-containing and fishless habitats. We found that adult eastern newts were unpalatable to predatory fishes (Micropterus salmoides, Lepomis macrochirus) and a crayfish (Procambarus clarkii), but were readily consumed by bullfrogs (Lithobates catesbeianus). The eggs and neonate larvae were also unpalatable to fish (L. macrochirus). Bioassay-guided fractionation confirmed that deterrence is chemical and that ecologically relevant concentrations of TTX would deter feeding. Despite predatory fishes rejecting eastern newts in laboratory assays, field experiments demonstrated that tethered newts suffered high rates of predation in fish-containing ponds. We suggest that this may be due to predation by amphibians (frogs) and reptiles (turtles) that co-occur with fishes rather than from fishes directly. -

This program allows students to learn about the rich diversity of plants and animals in the southern Appalachians. The field site is located on the Highlands Plateau, North Carolina, near the junction of North Carolina, South Carolina and Georgia. The plateau is surrounded by diverse natural areas which create an ideal setting to study different aspects of land use change and threats to biodiversity. The Highlands Plateau is a temperate rainforest of great biodiversity, a patchwork of rich forests, granite outcrops, and wet bogs. Many rare or interesting species can be found in the area, with some being endemic to a specific stream or mountaintop. Some of these are remnants of northern species that migrated south during the last ice age; others evolved to suit a particular habitat, with a slightly different species in each stream. -
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.

Ozier, and Alan Cressler. Biodiversity from caves and other subterranean habitats of Georgia, USA. Journal of Cave and Karst Studies, v. 82, no. 2, p. 125-167. DOI:10.4311/2019LSC0125 BIODIVERSITY FROM CAVES AND OTHER SUBTERRANEAN HABITATS OF GEORGIA, USA Kirk S. Zigler1C, Matthew L. Niemiller2, Charles D.R. Stephen3, Breanne N. Ayala1, Marc A. Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state. -

We investigated the concentration of tetrodotoxin (TTX) in sections of skin containing and lacking red dorsal spots in both Eastern newt (Notophthalmus viridescens) efs and adults. Several other species, such as Pleurodeles waltl and Echinotriton andersoni, have granular glands concentrated in brightly pigmented regions on the dorsum, and thus we hypothesized that the red dorsal spots of Eastern newts may also possess higher levels of TTX than the surrounding skin. -

Have Salamanders Declined in Ontario?
Have salamanders declined in Ontario? David C Seburn1 Erin Mallon2 1Seburn Ecological Services 2710 Clarenda St, Ottawa, Ontario, K2B 7S5 2Ontario Nature 214 King Street West, Suite 612, Toronto, ON M5H 3S6 Prepared for Ontario Wildlife Foundation Ottawa Field-Naturalists’ Club October 2015 Abstract Amphibians are known to be declining around the world. Although most affected species are frogs, salamanders are declining as well. The Ontario Reptile and Amphibian Atlas (ORAA) is a citizen science project that tracks reptiles and amphibians across the province over time. Data from the ORAA indicate that salamanders are absent from many historical areas of Ontario. This result could be from a true decline or a lack of recent observations from many areas. To test this we conducted surveys for salamanders in 25 historical 10x10 km grid squares across eastern Ontario. Result highlights: Checked 3876 cover objects in 25 grid squares Confirmed Red-backed Salamanders present in 21 of 25 (84%) squares surveyed Found 202 individual salamanders of 6 different species 90% of salamanders found were Red-backed Salamanders The median number of cover objects checked to detect a species varied from 34 for Red-backed Salamanders to >100 for Blue-spotted and Spotted Salamanders Found up to 3 species of salamanders per square Provided the first recent records for Spotted Salamanders in 4 squares, and for Blue-spotted and Two-lined Salamanders in 1 square Provided the first records ever for 4 species of salamander in 5 squares Our results strongly suggest that lack of survey effort explains much of the apparent decline of salamanders in eastern Ontario.
