Adults that run after touching a snake tongue also run faster than other adults in the absence of a predator. In some populations, densities are as low as 0.02-0.04 animals/m2. Comparative studies of macroscopic and microscopic features of spermatophores of some plethodontid salamanders. Mercury (Hg) causes a range of deleterious effects in wildlife, but little is known about its effects on amphibians. • CONTENT. If fish are present, larvae seek shelter and may hide for days even after the fish are no longer present. [3] This salamander is yellow or yellowish-brown, with two black stripes running down the back which tends to break up after the base of the tail. (2012). 1997. The pair may remain in this position for an hour or more. Our objective was to determine whether Hg affects performance and behavior in two-lined salamanders (Eurycea bislineata). 1984. Help us improve the site by taking our survey. having the capacity to move from one place to another. In the late 1980's significant genetic divergence was recognized among these groups, and the subspecies were elevated to species status (Jacobs 1987). [22] Tail autotomy is common in E. bislineata , as a result of a struggle with a predator. The northern two-lined salamander is a small salamander, with adults ranging from 65–120 mm in total length. Prior to 1987, the Eurycea bislineata complex was thought to encompass several subspecies distributed farther south and west of the current accepted range. Synchronous foraging and dietary overalp of three species of Plethodontid salamanders. Northern Two-lined Salamander - Eurycea bislineata. The aptly named Carolina Sandhills Salamander (Eurycea arenicola) is found in association with springs, seepages and small blackwater streams of the Sandhills region of North Carolina. Antipredator strategies of salamanders: individual and geographic variation in responses of Eurycea bislineata to snakes. Eurycea bislineata. and J.R. Bider. This dataset represents a species known range extent for Northern Two-lined Salamander (Eurycea bislineata) within the conterminous United States (CONUS) based on 2001 ground conditions. Jacobs, J. Research done in Quebec suggests a postbreeding migration into the forest occurs in June. They are found in the eastern part of Southern Canada and the U.S. Habitat. "Eurycea bislineata" (On-line), Animal Diversity Web. A high dietary overlap exists among the different sizes of larvae which feed continuously throughout the night and day. They have a yellow-brown stripe down the middle of their backs. [11] Communal nesting in northern two-lined salamanders has been documented on several occasions and localities; New York,[12][13] in Ontario,[14] and likely in Ohio. This may indicate an evolutionary trade-off (Petranka et al 1987). Body Traits. Harding, J.H. [16] The larvae over-winter in deeper pools not prone to freezing. SECONDARY SEXUAL CHARACTERS OF EURYCEA Anatomy of the temporal musculature and number of costal grooves between toes of the adpressed limbs were examined in all females collected with either male E. b. wilderae or morph A from the 16 localities. Adults may remain active in springs, streams, or water laden soil where temperatures are above freezing in winter months. The subspecies were Eurycea bislineata bislineata, E.b.

Adult and larval Northern two-lined salamanders also exhibit antipredation behavior. (1983). Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Upon finding the female, he will lift her by pushing his snout under her cloacal region or chest. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Here, we combine traditional molecular‐phylogenetic, multiple‐regression, nested clade, and molecular‐demographic analyses to investigate the relationship between phylogeographic variation and the hydrogeological history of eastern North American drainage basins in semiaquatic plethodontid salamanders of the Eurycea bislineata species complex. During this time period, males possess whitish lower eyelid glands, a distinictive mental gland on the chin, and cirri (protruding extensions of the naso-labial gooves). Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis. They reach less than 4 inches long and are a yellowish-brown color with many tiny black dots. Eurycea bislineata: Stejneger & Barbour, 1917:18. Jung Brown (2007). The races of Eurycea bislineata. Eurycea bislineata, Plethodontidae, Caudata. The Eurycea bislineata complex (“two-lined salamanders”) of eastern North America contains six described species, of which three have very similar morphologies and relatively broad geographic distributions, and three have more divergent morphologies with narrow geographic distributions. The species name bislineata means “two lines,” and refers to the paired dark stripes that run from each eye down the back to the tip of the tail They may also have black speckles. Sexual maturity is reached in this species at three to four years old. The Animal Diversity Web is an educational resource written largely by and for college students. Ducey, P.K. pp.168. Range. Petranka, J. [8], This species exhibits sexual dimorphism in the shape of the premaxillary teeth. Taxonomic History of the Eurycea bislineata Complex Until recently, the salamander commonly known as the two-lined salamander, Eurycea bislineata, held the distinc- tion of being the most widely distributed species of lungless salamander (Plethodontidae). First described by Jacob Green in 1818, the nominate species had a range extending Altogether 126 male specimens of E. bislineata were examined from other parts of its range Females may attach as few as fifteen or greater than one hundred eggs to the underside of firm substrate, usually rock, in flowing streams or spring water (Harding 1997). It is one of the most common salamanders of the Great Smokey Mountains. Already possessing more salamander species than any other state in the country with 63, North Carolina has just added one more to make it 64. Influence of observers and stream flow on northern two-lined salamander (, MacCulloch, R.D. Range of Eurycea bislineata. For a key to these forms see Mittleman (1949). Sexual isolation and courtship behavior in salamanders of the, Guy,C.J., R.E. Topics Geographic Range. The second migration is that of the newly metamorphosed juveniles leaving the stream, but they tend to remain closer to it. Background: The northern two-lined salamander is Connecticut's most common stream salamander. Adult Northern two-lined salamanders, 6.4 to 12.1 cm in length, are characterized by a broad stripe stretching from head to tail along their slender bodies. Burton, T.M. Animal Behavior, 38: 707-711. We measured the circulating T4 and T3 levels in the plethodontid salamander Eurycea bislineata at various stages of metamosprhosis using radioimmunoas… The underside of their tail is abright yellowish-orange. The larvae of, Crocker,J.B., M.S. Amphibians and reptiles of the great lakes region. Alternatively, adults may burrow deep into leaf litter, becoming inactive during cold seasons. Brodie. Recent evidence suggests Northern two-lined salamanders, in some areas of their range, attach eggs to vegetational carpets in fish free, acidic lakes (Bahret 1996). Some individuals, when confronted with a garter snake, will remain motionless when contacted by the head of the snake, but would engage in a protean flip, where the tail is held over the body when contacted by the snake's tongue. A second set varies both the period and concentration of T 4 treatment to evaluate the effect of different TH profiles on adult tissue shape. The male then releases a spermatophore which is picked up by the female(Harding 1997). EURYC'EA BISLINEATA 200 400 600km MAP. [3][4] Compared to many other species in the genus Eurycea, E. bislineata has a large geographic distribution. The water should also be flowing, and this is easily accomplished with an internal filter (the Duetto DJ50 is ideal) or vigorous aeration. They have a yellow-brown stripe down the middle of their backs. Classification, To cite this page: Both bislineata and cirrigera seem very tolerant of a wide range of temperatures and so a range of 15-22°C (1968). and L.A. Lowenthal. The ROM field guide to amphibians and reptiles of Ontario. (1963). Continued exploitation of Northern two-lined salamanders by humans, for fish bait, or destruction of salamander habitat could lead to reduction or extinction of local populations (Harding 1997). Salamandra bislineata Green, 1818 The northern two-lined salamander ( Eurycea bislineata ) is a species of salamander in the family Plethodontidae found in Canada and the United States. Adults range from 3 - 5 inches long. 587. The distribution of this species in Connecticut is quite extensive, with many known populations in every county. Ontogeny of diet and feeding behavior of Eurycea bislineata larvae. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. [2] Its natural habitats are temperate forests , temperate shrubland , rivers , intermittent rivers, freshwater marshes , freshwater springs , arable land , and urban areas . Salamanders of the United States and Canada. This species occurs from southern New York to Missouri, south to Arkansas, Tennessee, extreme northeastern Mississippi, northern Alabama, ... Northern Two-lined Salamander (Eurycea bislineata) Typical prey items for northern two-lined salamander larvae include chironomid larvae and other dipteran larvae, stonefly larvae, cladocera, and copepods. Organ, J.A. Journal of Herpetology, 30: 399-401. (2002). [5] The larval period of E. bislineata is variable depending on latitude. The northern two-lined salamander (Eurycea bislineata) is a species of salamander in the family Plethodontidae found in Canada and the United States. The ADW Team gratefully acknowledges their support. DOI: 10.1655/0018-0831-76.4.423 Most small streams in the wooded, mountainous areas of the range are rocky, which provides a good substrate for nesting, and lack large predatory fish. pp. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Larvae typically inhabit the flowing waters of springs or streams (Harding 1997). [7] The spermatophore of this species is described as conical, 2.5 mm in height and with a colorless stalk that tapers towards the tip. Fertilization occurs internally after the female collects a spermatophore in her cloaca. [3] The adults and juveniles tend to be restricted to the stream edges, hiding under rocks and other debris during the day. Larvae also evade predators by altering their behavior. [3] Observations of courtship in the species were made based on individuals held in captivity by Noble (1929), and a summary of these observations are: the male becomes restless, as if searching for a female. Holomuzki, J.R. (1980). Sexual dimorphism exists among males and females, but is more pronounced in the breeding season. A male uses his head to nudge or poke a potential mate, and encircles the female's head with the front of his body. Disclaimer: This tail-straddling walk may last for over an hour, at which point the male deposits a spermatophore, leading the female to walk over it, at which time she may either accept or reject the male's sperm. [20] In other areas, localized densities can be as high as 11 individuals /m2. The teeth of breeding males are unicuspid and elongated when compared to the shorter bicuspid teeth of the females. The Animal Diversity Web team is excited to announce ADW Pocket Guides! The circle marks the designated type locality. Wood, J. T., and N. H. McCutcheon (1954). the area in which the animal is naturally found, the region in which it is endemic. Adults may also consume other small invertebrates including earthworms and snails. Within this range, it appears to be fairly localized. Distinctive short, reddish brown gills are also characteristic of the larvae (Harding 1997). [21] Adults overwinter up to 80 cm deep into the soil of the stream bank in cold climates, but may remain somewhat active in southern regions, and may continue feeding during this period. The larvae act as opportunistic generalists as they mature, continuing to ingest large amounts of small prey after the developmental point when their jaw size can accomodate larger prey items (Petranka 1984). (1998). University of Michigan Press. Eurycea bislineata. Vanwormer, E. 2000. Nest-site selection by southern two-lined salamanders (. The male scratches the female's skin with his teeth, possibly allowing secretions from his mental gland to enter the female's bloodstream.

Four sub-species were recognized by the last revisor (Mittleman, 1949, 1966): E. b. bislineata (Green, 1818) in northeastern United States and southeastern Canada; E. b. cirrigera Male Secondary Sexual Characters of the Eurycea bislineata (Amphibia, Urodela, Plethodontidae) Complex in the Sourthern Appalachian Mountains July 1979 Journal of Herpetology 13(3):245 [3] Research done in the Georgia Piedmont on the closely related E. cirrigera, indicate that 65% of nests found were under cobbles (2.5 to 30 cm), 16% were under boulders (greater that 30 cm), and 19% were under slate tiles (30x30x1 cm), which were added to the stream experimentally. [10] To deposit eggs on the under surface of a rock, the female must flip on her back to make cloacal contact with the substrate. Its natural habitats are temperate forests, temperate shrubland, rivers, intermittent rivers, freshwater marshes, … animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature. The larvae measure 1.2 to 1.4 cm snout to vent length (svl) when hatched, and usually transform into semiterrestrial juveniles after two to three years as aquatic larvae. They are found in or near flowing streams with rocky bottoms. Eurycea bilineata is primarily insectivorous. It is hypothesized that these secretions may stimulate courtship behavior in the female. Harding, J. The breeding season lasts from October through May with females typically laying their eggs in April or May. The female eventually presses her chin to the male's glandular area at the tail base and the two engage in a "tail straddling" walk. Communal Oviposition in the Northern Two-lined Salamander (, Barr, G.E. The female eventually slips out of this posture and begins to straddle the male's tail with her fore limbs, while pressing her chin against the base of the male's tail. and K.J. Effects of biotic and abiotic factors of the distribution and abundance of larval two-lined salamanders (, Trapido, H. and R.T. Clausen (1940). placed in the synonymy of E. b. bislineata. Adults are also territorial, so if resources are scarce, the population is less dense. Parental care ceases after eggs hatch (Harding 1997). Global Distribution. THE two-lined salamander, Eurycea bis-lineata (Green, 1818), has an extensive range in eastern North America. Stewart, M.M. Summary Introduction Effects of metamorphosis on the aquatic escape response of the two-lined salamander (Eurycea bislineata) Emanuel Azizi1,* and Tobias Landberg2 1Graduate Program in Organismic and Evolutionary Biology and 2Biology Department, University of Massachusetts, Amherst, MA 01003-9297, USA Northern two-lined salamanders are often collected and used as fish bait by humans (Harding 1997). Within the ingroup, 270 … and E.D. Salamanders of New York. Abstract: Eurycea bislineata (Two-lined Salamander), is one of the cases where Ontario has one species from what is a whole guild of species farther south, and the map of the species occurrence in Ontario is mostly made up of holes between central southern Ontario and isolated records on the Moose River, Manitoulin, Moose Creek, and north of Sudbury. [11], Upon hatching, the gilled larva are about 10 mm long, and remain in slow-moving pools, or less frequently, hiding in crevices between rocks and boulders in swift-flowing streams. The range of Eurycea bislineata, the Northern two-lined salamander, extends south from southern Quebec and New Brunswick to northern Virginia, and west from New England to northeastern Ohio (Harding 1997). Adults touched by the body or head of a snake typically remain immobile. Bahret, R. 1996. In this study we attempted to examine the phylogenetic relationship of Eurycea bislineata, an east coast salamander by examining the Cytochrome b, and ND4 gene regions of the mitochondrial DNA genome. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Adult Northern two-lined salamanders prefer woodland or open habitats with sufficient cover provided by layers of fallen leaves, logs, or rocks. This material is based upon work supported by the Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Description. 2006 IUCN Red List of Threatened Species. pp. Four annectant subspecies are recognized­ bislineata, cirrigera, rivicola, and wilderae. In at least one region of their range, larvae may also live in lakes (Bahret 1996). The chosen response may be correlated with physical ability (Dowdey and Brodie 1989). In the southern portion of their range, such as New York, metamorphosis occurs at 50 mm total length or two years old, while further north, such as in Quebec and likely Ontario, metamorphosis takes place at nearly 70 mm total length, or three years old. Predators include birds, such as the eastern screech owl (Otus asio), snakes such as the eastern garter snakes (Thamnophis sirtalis) and ringneck snakes (Diadophis punctatus). [3], Because of its small size and localized distribution around streams, the northern two-lined salamander is preyed upon by a variety of animals. Northern two-lined salamanders exhibit complex courtship behavior. … [3], Once the larvae reach their maximum size, metamorphosis occurs. wilderae, and E.b. (Eurycea bislineata) Description These small, slender salamanders are usually yellow (although the color can range from greenish-yellow to yellow-orange). Historical versus Current Distribution - Northern two-lined salamanders (Eurycea bislineata) are the well-known “yellow salamanders” of the northeastern United States and eastern Canada. Population dynamics of. [3], This species prefers small rocky streams or seeps in forests, but may occur in moist areas far from running water. It may take place from September (in the southern parts of its range) to May (in the north). On either side of the stripe there are two thin black stripes that start at the eye and extend the length of their bodies. Ecology of the lake dwelling Eurycea bislineata in the Shawangunk Mountains, New York. More information: Bryan L. Stuart et al, A New Two-Lined Salamander (Eurycea bislineata Complex) from the Sandhills of North Carolina, Herpetologica (2020). Predator-prey interactions among fish and larval amphibians; use of chemical cues to detect predatory fish.. Taxon Information These adult salamanders may move over 100 m from the stream. These salamanders feed on a wide array of aquatic invertebrates. [3] Predators of the larvae are many, such as fish, crayfish, and other salamander larvae, such as the larger northern spring salamander (Gyrinophilus porphyriticus). [6] Northern two-lined salamanders are found throughout northeastern North America, ranging from central and southern Quebec, New Brunswick, northeastern Ontario, and the northeastern United States, from central Virginia and Ohio northwards to the Great Lakes. (1997). Four hundred forty-two sequences representing 1108 aligned bases from the mitochondrial genome are reported for the five formally recognized species of the E. bislineata complex and three outgroup taxa. • DEFINITION. and G.E. https://en.wikipedia.org/w/index.php?title=Northern_two-lined_salamander&oldid=974965944, Fauna of the Great Lakes region (North America), Creative Commons Attribution-ShareAlike License, This page was last edited on 26 August 2020, at 00:25. [5] On the side of the body are 14–16 costal grooves. Royal Ontario Museum, McClelland and Stewart, Toronto, Ontario. Although occasionally found several meters from a water source, adult salamanders commonly occur along stream banks. [19] Adult population densities are variable by habitat quality. The northern two-lined salamander ( Eurycea bislineata) is a species of salamander in the family Plethodontidae found in Canada and the United States. It is more water-oriented than the related northern redback salamander, and can often be found in and around water such as rain puddles, streams, swamps, and damp stream beds, whereas the northern redback tends to be found in damp ground, but usually not near open water. [18] The diets of the adults are more wide-ranging than the larvae because of the amount of habitat that can be exploited, both terrestrial and aquatic. Kozak, K.H. MacCulloch, R.D. Young and older Eurycea bislineata larvae differ from adults in coloration and markings. [9] Prior to egg laying, the female searches for a suitable oviposition site in the stream. Smithsonian Institution Press. Ratajczak, G.D. Grossman. Transfer of S. bislineata to Eurycea. Medially, the stripe may be marked with a row of dark spots. [15] The larvae do not begin feeding until their yolk sacs are reabsorbed, at which point they begin to feed on benthic invertebrates by prowling the bottom of the stream. Eurycea bislineata species complex. [3] Also, some data suggest this species may be found on stony shores of small lakes and rivers. Petranka, J., L. Kats, A. Sih.. 1987. The stripe, bordered on both sides by narrow black lines that may separate into dashes along caudal regions, ranges in color from yellow to greenish yellow or tan. A secondary row of spots may develop as the larvae age. The flanks are mottled grayish or brown. ... A wide range throughout the eastern United States. Babbitt (2002). Eurycea bislineata Two-lined Salamanders are slender yellow salamanders found statewide, often in or around streams. Its range includes the Blue Ridge mountains, Cumberland mountains, and the Cumberland Plateau. Salamander populations and biomass in the Hubbard Brook Experimental Forest, New Hampshire. Eurycea wilderae is predominantly found in the Nearctic region. Adults can also drop their tails (autotomy) which continue to move as the salamander escapes from a snake or other common predators including various mammmals, birds, and larger salamanders (Harding 1997).

(1975). Nest sites are frequently under rocks, sometimes logs, and perhaps vegetation. Yellow or mottled pigmentation extends down the sides, each with fifteen to sixteen costal grooves, and small legs to the yellow belly. [2] Its natural habitats are temperate forests, temperate shrubland, rivers, intermittent rivers, freshwater marshes, freshwater springs, arable land, and urban areas. Herpetologica, 43: 423-446. The tissues surveyed in this … The male adopts a distinct posture, bending his body laterally around her snout. The two-lined salamander Eurycea bislineata (Green 1818) has a wide geographic range. Females tend to guard nests for at least part of the incubation period lasting thirty to sixty days. Salamanders respond selectively to contacts with snakes: survival advantages of alternative antipredator strategies. cirrigera. It inhabits a wider range of habitats than the dusky salamander (another stream dweller), including streams that are scoured on a regular basis. A small (4 inches; 10 cm), slender salamander with a long tail. Bishop, S. C. 1941. Losing part of the tail increases the likelihood of surviving the encounter with a predator. About 75% of individuals dispersing over 100 m into the forest did not return, and they were believed to have been consumed by predators. Occasionally, specimens are found along larger streams and rivers, but nesting has not been reported in such habitats. Likens (1975). [4] The belly is pale yellowish, nearly transparent. Amphibians and Reptiles of the Great Lakes Region. Phenology, migrations, circadian rhythm and the effect of precipitation on the activity of (. However, if touched by the snake's tongue, adults may demonstrate running or jumping behavior as an alternative to an immobile response. Northern two-lined salamanders reach sexual maturity the first fall, or occassionally, one year after metamorphosis. The male may undulate his tail from side to side in a slow and exaggerated manner, and the female moves her head from side to side, alternately from the male's tail. Young larvae also possess one dark irregular stripe containing six to nine light spots along upper regions of each side. The majority of above-ground movements are made after dark and in wet weather. Additional synonymic details are present in Dunn, 1926. (2003). [3], The reproductive strategy of the northern two-lined salamander begins with an elaborate courtship. Three minutes is required to lay each egg in this manner, and up to several hours to lay an entire clutch. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. National Science Foundation The Northern Two-lined Salamander is one of our three small, slender salamanders in Vermont, along with the Eastern Red-backed and the Four-toed Salamanders. Adults range from 3 – 5 inches long. Ovarian egg complements and the nests of the Two-lined Salamander, LeGros, D.L. Larvae eat crustaceans and copepods in addition to aquatic larvae of midges, mosquitos, caddisflys, stoneflys,and beetles (Harding 1997). Noble, G.K. (1929). [17] Seasonal migration does occur, but not all individuals undertake them. There are four toes on the fore feet and five toes on the hind feet. Only one female typically guards a nest in cases where multiple females deposit eggs at the same site. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. 327. Dunn (1920) stated that the range of his new taxon is the “southern division of the Blue Ridge,” and Dunn (1926) reported that the distribution is “from White Top Mountain, Virginia; south in mountains to Clayton, Rabun … Different populations and individual adults within a population display unique behavioral patterns to snake contact.
